Introduction Insomnia is a common sleep problem for adults. To solve this, I developed Divcap, a powerful wearable device that can track people's data throughout the day and then treat people with sleep disorders through auditory and olfactory dimensions based on that data. After learning thermophilic fabrics in the Center for Digital Innovation, Tongji University as an intern, I made the original olfactory feedback products into the form of fabrics.

LIGHT URGENT TASK
Adults suffer from insomnia for 208 days of the year.
Short Term
People's clothing, food, housing, and transportation will affect sleep quality.
Conclusion The most fascinating aspect of sleep is that it’s highly connected to almost every aspect of our waking lives are highly individualized.This matters because it means that the best way to better rest and recovery through sleep science is an awareness of how sleep impacts our moods and feelings and health and how our lives in return - impact the way we sleep. However, Insomnia is a common problem for adults.
30%
of the general population complains of sleep disruption.
10%
have associated symptoms of daytime functional impairment consistent with the diagnosis of insomnia.
The National Institutes of Health estimates.
5. It is better to take a nap for half an hour in the noon, do not go into deep sleep.
Sleep is an interesting area of science. While there is still no agreement on “why” we sleep - there is plenty of evidence that sleep, as incredibly complex as it is is important for proper function of the human body. So, the problem of sleep is worth exploring and solving. In the spirit of humanism, I want to design a program that can intervene and regulate sleep.
6. Use habitual breathing. There are two basic types of sleep: rapid eye movement (REM) sleep and non-REM sleep (which has three different stages: Falling Asleep Stage, light sleep stage and Deep sleep stage).
Conclusion After researching some academic knowledge about sleep, I understand that minutes of sleep. By this, it means Falling Asleep Stage and Light Sleep Stage are quite important for getting a good night's sleep.
Academic Project Review Three projects are from the Dream Lab which is from the Fluid Interfaces Group at the MIT Media Lab. DORMIO builded future dream interactions. From this, I learned some techniques for detecting sleep. However, I think sleeping with sensors on hands is not very comfortable, this system could be implemented in other interfaces.
COCOON aimed to see and shape the dream. From this, I have a deeper understanding of the relationship between dreams and sleep. But I think this device is not easy to use and cannot be commercialized.
The content of the ESSENCE project is to release the corresponding odor based on human data. From this, I know the importance of olfactory perception and this project sparks my interest in olfactory research.

User Understanding
Motivation & Interviews To better understand the specific characteristics of people with sleep problems and their own experiences as well as to understand their expectations for solving sleep problems, I chose a group aged from 15-47 to investigate their reasons for insomnia. There were 35 interviewees, 23 of whom suffered from insomnia for a long time. Here below are three typical cases.

After so much academic research and brainstorming, I try to explore a product that can be worn on people to intervene and regulate people's sleep. In sketch, I considered the human-computer relationship and I was trying to design a product that can help sleep.
Conclusion
Design Concept
Among the insomniac people interviewed, they have taken some measures to treat: taking sleeping pills, using sleep monitoring apps, microcurrent stimulation treatment devices, etc. However, these products have not been treated for the user's own condition, and the treatment effect is not very good, and it is not a proactive intervention product.
I want to design a product that can treat people with sleep disorders through auditory and olfactory dimensions, combined with expression recognition technology and brain wave detection technology.
Experiment 1: Promoting Sleep Factors Verification Purpose
After the experiment, I compared the four groups of data and found that music can help to enter shallow sleep early 450s and aroma can help to enter shallow sleep early 900s.
Validation researches indicate that smell and music can truly promote sleep.
Experimental plan description
Analyze whether music and smell can promote sleep by comparing the amplitude of brainwaves when people sleep in the ordinary state with the variation of brain waves when people are accompanied by music or smell.

The main symptoms of insomnia are the effects on daytime performance, such as feeling tired, irritable, emotional disorders and inattention. It is vital to know a person’s all day mood rather than just detect his/her brainwaves at night. I hope to collect a full day's data of people and analyze the data in two aspects to get a treatment plan.

Three Trends in Technology
The fourth iteration of the design was inspired by the knowledge I learned about smart fabrics from my internship at Center for Digital Innovation, Tongji University in June 2020. Olfactory feedback wearable devices are currently quite thick and the most common is to use atomizer plate including my preivous three prototypes, which requires liquids and is not easy to carry. To solve this, I develop DivcapTex, a smart fabric with a scented structure can release olfactory feedback through fabric deformation after being energized.
DivcapTex Structure
The above structure is the same as the ShapeTex.
Kapton: Shape change material

Verification of the ShapeTex Structure After studying the paper ShapeTex: Implementing Shape-Changing Structures in Fabric for Wearable Actuation, I bought corresponding materials myself and made a demo according to their structure. When the voltage reaches 9V and the current is 3A, the fabric can really deform!
Because of how thin and light DivcapTex is, it opens up a lot of possibilities in designing scenes. However, it still takes a long time for research and development. I believe it illustrates a entirely new form of olfactory interaction and it has the

For the sleep scenario, it no longer needs a complex and massive EEG sensor and it can be directly attached to the face. It can be heated and deformed after receiving certain EEG data to release sleep-promoting fragrances.
For the social interaction scenario, it can be attached to the clothes as a role of toy. When you see a charming person that you would like to communicate, you can activate the DivcapTex, allowing it to deform to create beautiful patterns and release fragrances to attract attention.

Sens Coffee: The Bean Tales
Research Question
Research on the Experience of Coffee Shops
Redefine the way coffee is consumed Enhance its sensory experience
Coffee is the second largest circulating commodity in the world. However, in coffee houses today consumers tend to only interacts with coffee through our sense of taste, which is not conducive to the spread of coffee culture. Can we extend a sensory experience and design a synesthetic interaction for coffee?
I visited three coffee shops to grab a cup of coffee because I wanted to study the olfactory experience of coffee beans and learn about how to enrich the existing coffee experience process.

1. There is little interaction between the baristas and customers. 2. The barista could have shared some knowledge about coffee beans to people because many people do not know the varieties of coffee beans. 3. People do not have the chance to blend different coffee beans to modify their favorite taste, despite the huge varieties of coffee on offer. 4. The multi-sensory experience of coffee drinking is not strong enough.

Music Notes For Beans
Before making coffee: I chose to use a French Press to make coffee, because the coffee extracted by a French Press is pure and mellow. I bought an electronic scale to measure the weight of the coffee beans, making the experiment rigorous. Furthermore, I used a grinder to ensure a medium grind throughout.
According to my preferences and the characteristics of coffee, I make a note for each type of coffee. My measurement is based on the mellowness (0-10), sourness (0-10). (Note selection range: within the seven tones starting from Middle C)
Tasting coffee process:
According to the addition of the two scores, the lower the score, the lower the pitch. Among them, I think the two tones of Re and Fa cannot represent coffee beans, so I skipped these two tones.
2. Gently stir the coffee, then "chew" the coffee, making a "squeaky" sound. Finally, look for the characteristics and taste of the coffee.

Experience Route There are two ways to experience the coffee. This route is a stimulating way to blindly choose coffee. No.1 is a gumball machine, where the customer can't determine which coffee beans are contained in the blend inside. When the customer pays, they can go directly to the bar counter (Zone 7), give the coffee to the barista, and then choose their coffee style. While customers are drinking their coffee, they can see a variety of sustainable products made from coffee grounds in Zone 8. The second route is through Zones 4, 5, 6, 7, 8. In this route, people have the ability to choose what kinds of coffee beans they want. The rest of the procedure is the same as described above. In conclusion, through this coffee experience process, not only can people choose the type of coffee bean, but they can also have the ability to choose the style of coffee they enjoy.

CONSEQUENCES FOR SURVIVAL
Introduction It is clear from the state of the world that humans have little respect for our natural environment, and wanton emissions of carbon dioxide are causing a phenomenon, I developed a special mask for the Post-Anthropocene times, using a“what if” scenario: what if we continue to release pollutants into the environment as we are doing now, then will we need to one day maintain the environment by limiting the gases emitted by human breathing?
Video: http://www.zhuyechen.com/algae-mask/
In the face of natural disasters, mankind appears very small. Humans have to design products that protect themselves, such as masks.
The Change in CO2 Concentration Humans think that they are the masters of the planet. They destroy the ecological balance, resulting in the destruction of the natural environment and leading to a variety of disasters on earth. Earth is again facing the stresses implicated in its past mass extinctions, including marine anoxia, , warming, ozone loss and increased UV-B radiation, hypercapnia, acid rain, atmospheric oxygen depletion, as well as unprecedented threats in habitat destruction and pollution.

Human recklessly emit polluting gases from factories; use cars as vehicles in large quantities; throw garbage into the ocean with abandon; cut down or burn trees. These actions raise the level of carbon dioxide on earth.
The world is running out of food but we still continue to over-populate the planet, use up resources and ignore all the warning signs. In this scenario, a group of people use synthetic biology to create microbial stomach bacteria, along with electronic and mechanical devices, to maximise the nutritional value of the urban environment, makingup for any shortcomings in the commercially available but increasingly limited diet. These people are the new urban foragers.

Sketch Ways to use the product
I explored the shape and function of this speculative product. This includes the structural design of how to keep chlorella alive in the mask.
Ways to show pollution
6CO2 + 12H2O = C6H12O6 + O2 + 6H2O In addition to reducing CO2 content by reducing factories, low-carbon travel, etc., plant photosynthesis can also reduce CO2 content because it can convert carbon dioxide to oxygen.
Masks are worn in front of people's mouths and noses to block bacteria. This inspired me, because people breathe through their mouth or nose. I want to design a mask to prevent people from releasing CO2 into the environment.
The human breath is almost silent, so people don't realize that the products of their breath are also contributing to the greenhouse effect. Automobile exhaust is a major cause of the greenhouse effect, and the emission is loud. So I want to compare the sound of human breathing to the sound of car exhaust emissions. The sound makes people feel the emission of CO2 through hearing.

Chlorella is a biological material, which conforms to the concept of sustainable development. The algae balls in the picture were used for photosynthesis experiments and proved that chlorella could still survive in this form. I'm going to grow chlorella, add sodium alginate and calcium chloride to it, and make algae balls like the pictures above.
A mask that seals the mouth and nose tightly. that can convert carbon dioxide into oxygen, thereby reducing human pollution in nature.
I want to put a carbon dioxide sensor and a speaker in the mask. The higher the concentration of carbon dioxide received by the sensor, the louder the sound of car exhaust played by the loudspeaker. In addition, LEDs can allow people to visually perceive CO2 emissions better.
My hypothesis In the post-Anthropocene era, our new relationship with the natural world and with sociotechnical systems are calling these previous understandings into question. What if humans continue to release pollutants into the environment, cut down plants arbitrarily and create population booms, then we may only be able to maintain the environment by limiting the gases emitted by human breathing.

The prototype warns that the human breathing is also a form of environmental pollution. Therefore, if human beings do not stop emitting CO2 recklessly into the air, then in the post-human era, human beings can only control their CO2 emissions to protect the environment.

Further Exploration Algae Mask makes audiences think: if we need to control human breath to protect the environment in the future, what kind of world will we live in? What can we do about it?
Sustainable Idea
For myself, I found the material "chlorella" in the production process
Clean chlorella treated with broken cell wall digestibility can be made into takeout boxes using the above experimental method.
For technical reasons, it may work not very well. But in the spirit of sustainable recycling, I tried more experiments with chlorella. Chlorella is a biological material, which conforms to the concept of sustainable development.

Experiment Process 1: The mixture liquid of chlorella with sodium alginate. (1:30)
Speaker The sound plays a critical role. The emission of industrial exhaust gas is currently the most harmful factor. By auditory process of human exhalation, everyone is aware that we are exhaling exhaust gas.

Rationality
Social Media Platform Analysis
Exploration of sensibility and reasonableness Promoting fairness on social media
Today, with the internet as ubiquitous as it is, information resources are growing rapidly. Although mass media has brought people a wealth of information resources, this often confuses people, affecting people's moods and falsely manipulating public opinion.
Humans never stop looking for rationality.
I studied the interface structure of six commonly used social media platforms.

Introduction With the prevalence of social media manipulation and
1.4 billion Internet users 0.7 billion active social media users
has rightly been questioned. To address this, I developed social media platforms to classify user comments according to their emotional sentiment. In this way, users will be able to identify which comments are positive and which are negative, which then allows us to 'sort by' according to the sentiment we wish to explore. My intention is to encourage users to explore public opinion outside of their echo
Video: http://www.zhuyechen.com/emofirefly/
The internet gives people the platform to express their opinions and become increasingly prominent. They obstruct, muddy and even manipulate "internet public opinion", greatly affecting the normal expression of public opinion online, and increasingly arousing the dissatisfaction and hatred of netizens.
The Crowd: A Study of the Popular Mind
Conclusion
“The masses have never thirsted after truth. They turn aside from evidence that is not to their taste, preferring to deify error, if error seduce them. Whoever can supply them with illusions is easily their master; whoever attempts to destroy their illusions is always their victim. An individual in a crowd is a grain of sand amid other grains of sand, which the wind stirs up at will.” - Gustave Le Bon
Over the years, the comment function on social media platforms including Twitter, Facebook, Instagram, TikTok, Weibo and Bilibili has developed a growing number of ways for people to express their comments and opinions, including text comments, liking, and reposting, as well as the ability to post emojis and images in the comment area. However, these mainstream platforms still lack the ability for people to truly convey their emotional expression. And in the comment area, opinions are negative trend.
Research on Twitter Reasons for choosing Twitter
Interaction Prototyping and Evaluation Tweet Structure Analysis
1. Twitter is a tool that users use to share with the world. 2. Twitter has helped bring the world closer together by giving everyone a microphone. 3. Twitter is now an old platform by social media standards and needs innovation to gain more younger users.
Content
Users' Feelings Introduce a Dislike button besides the Like button, or features similar to YouTube and Facebook. By the way, I love and enjoy Twitter.
General Feedback
Twitter desperately needs nuance in the convos here. When someone tweets about something sad, something that rightly causes anger, etc, we have to give it a like to acknowledge we read it & are with them. But sometimes, a Like seems so inappropriate, ppl reply w.”that’s a like of” Twitter has a harassment problem, and every woman on this site has seen it. A man can continuously antagonize survivors and shrug off mass reporting, but the moment a woman shows anger at him, or at the system enabling him, she is punished. We’ve seen it time and again. I ‘m beginning to feel like my voice doesn’t matter anymore. I tweet out my opinions and nothing but silence. Why? I’m struggling with this today.
Conclusion 1. Strengthen the distinction between positive and negative emotions 2. Strengthen post moderation and combat harassment 3. Fully meet people's needs for self expression
Comment
Conclusion The Tweet page consists of four parts: Content, General, Feedback, and Comment. Replies. Words + Pictures + Gif + Vote + Locations Retweet. Like Share. Share tweets within or outside the platform. I will redesign the Feedback and Comment sections.
I proposed three Assumptions and made a simple interactive prototype. I found three users to show them several new comment functions. In the process of communicating with them, many new ideas emerged.

Problem Definition
Design Aim
Schematic Diagram
manipulation by actors commenting in bad faith.
Design a plugin that can add people‘s emotions before they comment. Comments will be categorized into four kinds of emotions: Gloomy, Cheerful, Annoyed and Neutral.
After activating this plugin, comments on social media platform will be divided into these four categories, so that people can more intuitively check the emotional tendency of comments. In addition, users can conduct emotional evaluation when making comments, which can more directly express their own emotions.
2. People can't express their feelings through comments visually.
Design Inspiration Nature provides rich precedent for the ability for individuals to unite as groups. The sound of crickets chirping is the expression of both an individual’s voice, and a greater chorus of many insects, coordinated in a decentralized manner to the collective whole. The overall appearance is of an organism of much greater size and power than would be implied by a number of disconnected individuals. Reference: Berke, A., Sanchez Lengeling, T., Nawyn, J. and Larson, K., 2019. Bike Swarm. Conference Companion Publication of the 2019 on Computer Supported Cooperative Work and Social Computing,.
For comments, users take corresponding interactions: 1. Give monetary gifts to comments. The more positive gifts, the comment is highlighted, and the more negative gifts, part of the user’s ability to comment will be restricted. 2. Users can see comments similar to their own. Design a tangible interface that can dynamically showing the magnitude of the change in the mood of the commentator and strengthening the sense of belonging among people who share the same feelings about the same topic at that moment.
Design Concept of the comment is of the same position, it is considered a group. vibration frequency.

Product Usability Evaluation User 1 Overall Score: 65 User 2 Overall Score: 88 User 3 Overall Score: 76 The overall evaluation is good. Although one test user thought that it is not meaningful to do sentiment analysis on social media, he believes that this type of software is a place for people to express their opinions freely, and there is no need to classify comments. The combination of emotion analysis plugin and the tangible interface will be a new way of social interaction in the future.
GSR Sensor, Arduino Nano, LED Soft Board
Note Due to lack of time, I made the prototype into the shape of a wooden box. And the modeling behind the mobile phone case lacks more detailed exploration. The concept is actually a mobile phone case or smart mouse
When people express their emotional opinions on social software, the GSR sensor will detect the changes of people's emotions to verify whether the user's emotional comments are true. The intensity of emotional change is enhances people's sense of belonging.

With the rapid development of information today, young people have become "workaholics". No one cares much about their physical condition, and there is no time to get enough check. Some aging diseases are getting younger. Based on the principle of intelligent medical technology, I conceived four medical devices that can be skillfully combined with public places, so that people can take advantage of fragmented time to conduct physical examination and understand their physical conditions.

From the data, it can be seen that the number of people with Chronic Diseases in cities is higher than that in rural areas. It may be that people in the countryside live in healthier environments than those in the city and people in the city are under pressure from work and don't care enough about their health.
Expert Opinion Prevention is more important than cure. Individuals can assess their risk of disease based on 19 factors, including age, height, weight, previous illness and so on. In addition to reasonable exercise, it also needs to regularly go to the hospital to check.

Design Opportunity
Physical examination is very important. People's health status and potential diseases can be found through physical examination. But now fewer and fewer people go for physical examination, and their enthusiasm for physical examination is somewhat reduced. Why does this happen?
Most people think that the disease is far away from their own. However, when we suddenly fell ill, we find that the disease is in fact around us. So we should always pay attention to our own health. Only a healthy body can ensure that we go further and further in our career and life.
In order to find out about people lives and their attitudes on physical health and health centers,I interviewed several people.
Design Aims Aimed at people aged 25 to 50, who are busy at work. Promote people to keep in control of their physical conditions, prevent the occurrence of chronic diseases, and go to the hospital for treatment as soon as possible. To design four sets of devices that can detect people's physical conditions in public places where people often pass by. At the same time, there is a mobile app that can display and record people's physical conditions in detail. Name: Li Chen Age: 25 Occupation: HR Assistant

The reason why I choose the mirror is that everyone will look at their face in the mirror, and the bathroom is one of the places that people often go.
The reason why I choose the escalator is that it can be seen almost everywhere in public places, such as subway station, and people touch the handrail in the escalator directly.
I chose the urinal because everyone needs to go to the toilet. If you can check the composition of your urine after urinating, you can better understand your health.
Anyway, the device is in direct contact with people's face.The toilet mirror is just one of the more appropriate scenarios I can think of.

The reason why I choose the subway platform is that the subway is the most popular means of transportation. There are a lot of people in the subway and it takes a lot of time for people to wait in front of the platform. Therefore, I plan to use the time of waiting for the subway to let people do tests. So people can know their physical conditions while waiting.

Exploring the musical interface between humans and plants
Plant Communication
Project Human-plant interaction
Composition Tangible musical interface design Sound design
Date Oct. 2020 - Apr. 2021
Introduction To explore how to visualize plants inaudible sounds, I designed PlantMax, an interesting interactive interface for plant music. It combines a GSR sensor with capacitance sensors to capturer plant data, which can be processed by a computer and transformed into music that the human ear can perceive. Giving plants a voice, a possibility to respond and engage us would lead to new forms of entertainment, enhance our lifestyles and form a new environmental computational platform that can be used to make a “dialogue” between humans and plants. By reusing what nature has given us and designing an organic plant interaction, we can start a digital revolution back to nature.

Plant HCI
One of the striking differences between plants and animals is that they cannot move in response to changes in their surroundings. Plants are often thought of as lower creatures, lacking the typical means of communication with which we are familiar, such as sound and gesture. However, they have evolved a number of strategies to listen for and respond to harmful external conditions. Plants have no specialized organs for hearing, seeing, smelling and tasting, and their movements are usually too slow to be detected by the human eye, but they have advanced sensory systems - several receptors distributed horizontally throughout the plant. Plants also have special communication strategies that produce electrochemical reactions to the environment around them [1]. Recent advances in plant biology have shown that when plants are in a state of dangerous stress, the amount and properties of volatile organic compounds released into the atmosphere will change [2]. These molecules can be eavesdropped by nearby unstressed plants and enhance a rapid defense response to impending stress [3]. For example, plants not only release volatile compounds to attract pollinators and animals to ensure seed reproduction and diffusion, but these air signals have also been shown to be involved in plant-plant communication [4]. Runyon et al. [5] demonstrated the ability of parasitic plants (Cuscuta pentagona) to smell the presence of nearby tomato plants and grow towards them. In addition, Engelberth et al. [6] showed that when plants are attacked by herbivores, they can sense volatile organic compounds released by nearby plants and enhance timely defense responses to impending stress factors.

Cyborg Botany The Fluid Interfaces group of the MIT Media Lab uses plants as sensors to connect to the digital world, forming an interface that can perceive the environment and present feedback Growing a Green Future, 2012 Anna Garforth used moss in various designs and created green walls to give the building a more natural feel.
Florence People only need to input content on the terminal device to realize the “communication” between humans and plants. After the input information is processed by natural language, it will be mapped into certain emotions, and plants will respond to human emotions.
Das Verschlossene Paradies, 1995 Herman de Vries tells the story through the arrangement and combination of plants. It is a kind of creation to express emotion.
Pieces for Plants, 2013 This project is a work of plant and human interaction through the use of highly sensitive capacitive sensors. When people get close to plants, they can hear the plants reacting to their presence.
Bio-Box, 2013 This project establishes audio communication between different ecosystems (mosses and algae). These bio-communication systems generate tiny voltages as a human gesture in response to their physical stimuli, producing audible audio.
Design Concept Nature is filled with countless beautiful creatures, many of which have unique senses and expressive powers. They can sense the environment and other living things and regenerate, drive or grow. Unlike our interactions with traditional digital devices, our interaction mechanisms and channels of communication with creatures in nature are subtle. Plants, for example, know how to express themselves, synthesizing and transmitting large amounts of information through electrical impulses and chemical signals. If plants could talk to us, what would they say? Also, if we could talk to them, what would we say to them? Combining the knowledge of biology, art, design and engineering, I created a Plant Musical Interface (PMI) through the power of music, which enables people to express themselves together with plants through music. In the design process, I focused on plants, used a Galvanic Skin sensor to measure the bioconductivity of plants, and transformed it directly into sounds that representing plants. At the same time, I designed the plant as a capacitive touch interface, so that users can touch different leaves of the plant and generate mysterious music processed by different music synthesis technologies, so that users can interpret the beauty of life with the plant through electronic music.

Hardware Design
PlantMax generates sound all the time, visualizing the "physiological state" of the plant. PlantMax has two forms of interaction. When users engage in contactless interactions (such as approaching with fire, high-fiving, etc.), PlantMax responds to these stimuli in the form of sound changes. PlantMax is a music control interface when users engage in contact interactions (such as stroking or tapping). Users can change the area and duration of contact between the hand and the blade to produce different sensory sounds. The reason there are two modes of interaction is that PlantMax uses two kinds of sensors - a GSR sensor and a capacitance sensor. The non-contact interaction changes the plant's physiological values, which are obtained by the GSR sensor, and thus the plant's initial sound. Contact interaction mainly changes the capacitance value between people and plants, thus changing the parameters in each music synthesizer to change the sound. The sound changes produced by non-contact interaction are subtle, while the music produced by contact interaction is more obvious. I used Arduino Mega 2560 to collect all the data from the sensors. Then these data are fed into Max/ Msp, through a certain music synthesis technology to form a unique music. One electrode of the GSR sensor is connected to the leaf (stem) and the other electrode is connected to the soil (water). There are also nine capacitive sensors, each connected to nine different leaves. In the circuit of this capacitance sensor, I used a resistor of 1M. The resistance of this value can detect whether the finger is touching the sensing surface. By this, it means that the capacitance value changes only when the finger is touching the plant.
What is PlantMax? 1. A tangible music interface beyond a graphical interface. 2. Using sensor network breaks the traditional interaction experience between people and plants. 3. Expresses the plant signals that people can’t feel through music and enhances people’s cognition of the world.
Contact Interaction
Non-Contact Interaction
By connecting nine capacitive sensors to a single plant, the position of the plant leaves can be determined more accurately by observing the frequency affected by the user's touch signal. However, plants have complex and dynamic electrical structures. There will be some interference between these nine sensor. This means that the quality of the music generated each time is erratic, and more optimization needs to be done.
Sound Design
I tried a variety of music synthesis techniques, such as Texture Synthesis, AM, FM, Addition Synthesis, Reverb, etc. After a number of user experience tests, the Texture Synthesis technology was abandoned because its sound was not good enough to represent the characteristics of plants. The final music synthesis technique will be described in detail below. The overall logic of the program is as follows: 60000 bioimpedances of the plant are obtained by the GSR sensor in advance (1 data is collected in 1s.) and then these data are converted to Digital to Analog Converter. Serial number 1 is an audio signal with 60,000 data stored in the buffer~ (amplitude range: -1. ~ 1.). In addition, the GSR sensor captures the plant’s bioimpedance in real time at a rate of 10 data points per second, constantly updating the stored data. This is the sound produced by the plant - the purest sound. The other compositing technologies listed in the serial number all require the interaction between humans and plants to produce sound changes, that is, the compositing technologies required for the music made by humans based on the interface of plants. Their composition realizes the essence of PlantMax: human-plant interaction. Serial number 2 is used to change the playing speed of the original plant music. Serial number 3 and 8 are FM Modulation. One of the characteristics of FM is the ability of consolidation, which can realize the time-varying control of the spectrum content. It is more in line with the characteristics of natural sound as the spectrum content of sound in nature often has complex dynamic changes. Adjusting the part of serial number 3 can change the frequency of the carrier oscillator signal. When the frequency is low, the tremolo effect will be produced. With the gradual increase of the frequency, the tremolo effect will gradually disappear, and more sideband waves will be generated as well as the timbre will start to change. Changing Ratio can give the original plant music a metallic feel. Serial number 4 can make the music produce empty inspiration. Serial number 5 is to make the music reverb. Serial number 6 can make the music cloudy. Adjust the Lo, Mid and Hi parts of the serial number 7 to make the music more layered. Serial number 9 is an additive synthesis technology, whose principle is to superposition multiple harmonics of different frequencies and amplitudes to obtain harmonic-rich compound sounds. Based on this synthesis technique, the sound waveform generated by the plant can be superposed with the sound waveform generated by the human touching the leaves, and the resulting sound fully embodies the theme of the “dialogue” between the human and the plant.

Help children with autism understand the appropriate social distance
The prevalence of autism has risen from 5000 to 1 in 1975 to 54 to 1 in 2021, making it the most common and highly prevalent developmental disorder in the world. Autism spectrum disorder (ASD) is a broad developmental disorder characterized by varying degrees of communication difficulties, social impairments, behavioral abnormalities, and repetitive behaviors. In particular, deficits in face-to-face social communication are most common among autistic children, who are therefore more likely to be isolated and unable to integrate well into society.
On April 3, 2021, we asked for information about autistic children through an online communication with a teacher from Beijing Stars and Rain Education Institute for Autistic, an educational institution that provides services for autistic children and their families. In the interview, the teacher shared a video case: a basin of autistic children for water use, there are a red line. The purpose of this red line is not to worry that he can't see the water line clearly because of his vision problems, nor is he worried about his inability to concentrate and cause too much water, but to establish a norm for children with autism. Without norms, they don't know how much water to hold, and what is the "clean" standard for a "clean table".

Dr Ralph Adolphs, of the California Institute of Technology, used information collected from the Autism Research Project and the Autism Gene Resource Exchange (AGRE) on children's social behaviour. They compared the scores of 766 children with autism with 766 unaffected siblings on a standardized questionnaire on autistic social behavior.
79%
79% of children with autism were less aware of proximity and more likely to invade personal space than their normally developing siblings.
Social Distance Social distance is a very important factor in social interaction. It is one of the six basic non-verbal social factors (smile, nod, eye contact, gestures, social distance and physical contact). Having a good grasp of social distance is crucial to successful socializing. Conversely, inappropriate displays of social distance tend to cause the other party to feel their personal space is being invaded (resulting in strong discomfort) and lead to misunderstanding of social intentions (e.g., personal aggression, indifference, etc.).

Social space, 3.7m
Children with autism are often isolated due to social barriers. Without proper intervention, it is difficult for children with autism to carry out correct social activities, and social distance is an important factor in social skills. In response to this problem, in order to help children with autism to perceive and understand the social distance in social activities and make correct behaviors, we designed wearable smart Blooming Distance to help them perceive social distance.
In this model, private space is generally used for hugging, touching or whispering; Personal spaces for interaction with close friends or family; Social space is the scope of interaction with ordinary people; Public space is the distance kept from strangers in public. In addition, social distance includes not only the distance between others, but also the relative direction between others. For two people who are not very close, standing side by side in a crowded space is often more natural and comfortable than standing face to face.
Research on preferences of autistic children Color: Children with autism don't like yellow, they prefer brown; Overall preference for cool colors over warm colors. Its color order is: green, blue, red, purple, orange, yellow. Shape: Because autistic children have a defective understanding of things, their mental development is not mature, and they can only distinguish simple shapes. Children with autism use visual observation as their main learning method, and children with autism have a long-term interest in a particular shape. The overall appearance needs to adopt relatively simple lines, such as cylinder, cone, cube, cuboid, ball and other shapes, which can bring them different feelings.
Design Opportunity 1. Social distance is an abstract concept for children with autism, and it is difficult for children to understand what the appropriate range is in the interaction with people. Furthermore, it is difficult for them to have such self-awareness. So we can define a standard for children with autism: what is the appropriate social distance. 2. Many children with autism will show the high sensitivity on the sensory system, such as to sound, light, temperature, etc. Therefore, children can be presented with a rich variety of graphics (such as a kaleidoscope), through visual stimulation to attract the attention of children with autism.
Design Concept Children with autism are often isolated due to social barriers. Without proper intervention, it is difficult for children with autism to carry out correct social activities, and social distance is an important factor in social skills. In response to this problem, in order to help children with autism to perceive and understand the social distance in social activities and make correct behaviors, we designed wearable smart Blooming Distance to help them perceive social distance. When a person came to socialize with him face to face, when the distance from the autistic child was gradually reduced to 3m, the flower on the chest would slowly bloom; But when less than 0.4m, the flower will gradually close. - To encourage autistic children to get closer to others.
