Exhaustion stage

Stress toys mainly play a role of adjusting users' attention in a small range. Users can diver t their attention and then relieve their emotional stress during the operation.

Users shift their attention while playing, and also change their cognitive assessment of stressors and trigger positive emotions to offset the negative emotions.

Doctors and counselors play an important role in t h i s s t a g e. S t r e s s toy s serve as an avenue or aid to psychological and physical therapy to help users return to the original state.

Chart: An overview of symposium participants

Picture: Before the symposium (photographed by Geng Ruihong)

Defects in one-handed operation Altough the elongated shape makes it easier for fingers to slip through the gaps between the rotating bodies, and therefore easier to grip with one hand. But the elongated shape is less space-efficient, reducing the volume of the flat rotating body to make it easier to operate with one hand.

Longer rotation The current prototype rotates with a lot of vibration, so the rotation time is not very long compared to similar fidget spinner. The persistent rotation may have something to do with the craft.

Test

Quantitative Test Experimental objective Test the effect of operating the prototype on the stress level of the subjects (psychological significance). By comparing the time consumption of the experimental group and the control group, the influence of the stress toy on the stress state can be obtained.

Control group While the researcher was delivering 32 questions of 2-digit additional and subtraction to all the subjects, they were required to calculate the number as quick as possible and try to keep the accuracy at the same time.

Experimental group While the researcher was delivering 32 questions of 2-digit additional and subtraction to all the subjects, they were required to calculate the number while playing the prototype with the normal rate.

Results analysis Since mindfulness is also a stressful state, it makes sense that the control group would take slightly less time than the experimental group. Out of the 30 sample results, only one sample showed that the control group took longer time than the experimental group, which might be caused by the subjects being too nervous. Although the time spent by different subjects fluctuated greatly, the change rate was relatively constant at about 20%, with an average change rate of 19.25%. This means that operating the prototype reduced stress levels, but only up to a point. This slight effect is also one of the expectations of stress toys, toys with too much fun may have a negative effect on the user's daily life.

Com-compost Community waste reuse plan Service Design

1st Prize of ‘2020 National College Students Industrial Design Competition, Tianjin division’

INTRO A large amount of garbage is produced in urban communities every day. It is not only produced, but also needs to be sorted, transported and disposed of. In these processes, many resources are consumed and wasted, making it difficult for resources to flow effectively within the community.

GOAL To create a way of life that makes use of residents' free time resources and reduces the waste of human and material resources in the recycling process.

Background City as Context

235602

thousand tons

In China, the year household waste in cities is about 235,602 tons of household Although 99.7 % of this waste is treated, most of it is through low-recovery methods such as landfills.

Zero-waste city

program

In some areas, the utilization and disposal of solid waste are not considered seriously, which affects the sustainable development of urban economy and society. Therefore, the Chinese government has launched a zero-waste city program aimed at improving the efficiency of the current waste-disposal systems.

Social needs

of residence

The tendency of urbanization and the quick flow of population in cities has made people concern about personal communication among city residents. But some of the residents' autonomous organizations do not provide targeted support for residents' social activities.

Problems Kitchen waste and fallen leaves are not effectively recycled

The relationship between the residents lacks stability

Graph: The generation and disposal of waste

Picture: Relationships change in the city

Plants that are maintained in the community often use inorganic fertilizers, and the falling leaves, treated as a kind of garbage, are totally burned. This kind of waste disposal method of mass incineration or landfill is difficult to improve from the upstream industry in a short time.

The change of population structure not only changes the existing living and social pattern of urban community residents, but also exer ts a subtle influence on the psychological state of urban population.

The Underlying Concerns City

A better livable urban environment

Uncertain effectiveness.

• There is a higher green coverage in the city. • These green areas are expanded for the leisure life of the citizens.

• It may not be suitable for the government to promote the act of antonomy, for it may cause some unintended knock-on effects.

More efficient recycling of waste • Waste generated in communities can be collected more efficiently. • Reduce the resource consumption in transport by distributed solutions. • Promote more sustainable waste recycling alternatives.

Communities with closer relationships • Doing meaninful things together promotes interpersonal communication. • Fun activities bring communities together.

Community More efficient waste sorting, storage and disposal. • Voluntary sorting and recycling by residents. • More effective recycling programs within communities.

Stronger interpersonal connections. • Residents can increase communication with each other. • There can be greater solidarity among residents.

Family

Community Difficulties in management. • It has always been difficult for different families to have good coordination and ef fectively motivate community members.

Financial problems. • Lack of funds restricts the enthusiasm of many residents' self-governing organizations to carry out management activities.

Family A positive participation mindset. • It can be a bit nerve-wracking for newcomers to get involved in some group activities.

Better integrate into the community culture.

New social connections with others.

• Older people can bond with other members of the community. • Children can participate in community activities with other children. • Workers can participate in community maintenance and improvement.

• Starting a new social relationship can be difficult, especially when people don't know other's personal traits and preferences.

Problems and Solutions: through sticky notes.

The brown cards represent pain points related to the environment, while the green cards are more interpersonal traits. New concerns and issues may arise in addressing these environmental and human-computer relationship issues, and these emerging issues are presented with white letters.

Children lack opportunities for playing with others. A lot of garbage is produced in the community.

Families are more likely to play with their own family members. The number of plants is not enough in communities.

The leaves inside the community need to be cleared. Reduce the burden of garbage disposal in the community and promote communication among children by designing games and small competitions to get children interested in collecting leaves and sorting household and kitchen waste.

Not all games and competitions are suitable for children. Children's role in garbage sorting can be really limited.

Old people who live alone find it difficult to fit in community.

Parents have less free time.

Residens can plant vegetables in family units, with parents doing most of hard work, while the elderly can provide guidance. The elderly can also perform maintenance work such as watering.

Not all families have a lot of free time, and keeping everyone motivated can be a challenge.

Community plants maintenance.

Elderly people from different families can take care of community plants by working together to maintain the functions and services of community.

The health status of the elderly varies greatly in different ages, and not all the elderly have the ability to take care of plants

Neighborhood committees are usually reluctant to get involved in the organization of activities. Low waste utilization. There is a need to introduce new products and systems to help reuse resources within the community. Composting of fallen leaves and kitchen waste is a good way to reduce the cost of community sanitation.

After the compostable material is collected, it needs to go through a second screening and treatment to produce the material for composting. 19


Ecology Map Possibility

Residents' strong social needs The expansion of cities and the strengthening of community population mobility have restricted the communication of residents. Residents need a way to socialize offline, such as having parties, collaborative community services, salons, and so on.

Sustainable communities Due to China's carbon peaking and carbon emission reduction goals, communities also need to save energy and reduce emissions. Obviously, community managers need to fully mobilize the power of residents.

Distributive solutions The distributed solution within the community should be based on the grouping and division of labor. Different groups support each other to achieve a common goal of energy conservation and emission reduction.

From garbage to compost material A lot of organic waste is produced within the community every day. In addition to centralized incineration or landfill treatment, the waste can also be used as compost materials. And the composting process can be dealt with the residents themselves.

Synaesthesia is a sensation experienced in a part of the body other than the part stimulated. Although synaesthesia is mostly applied in literature, it is also a psychological phenomenon.

Application in design

Literary application

The growing music market

Engaging with music (2021)

Designers help users intuitively feel synesthesia through some technical means. In other words, synesthesia in design is a representation of psychological phenomena in the objective world, such as the conversion of audio signals into recognizable images and so on.

Synesthesia often appears in the form of a figure of speech, such as the phrase "a passing breeze carries a scent like a faint song from a distant tower", which links hearing and smell together.

Analysis SWOT Analysis Strength • Some music speakers use static electricity and other ways to create a connection with the music source itself, in the process of using this type of sound users will get some new experience. • With the rapaid development of technology, the structure size of speakers can be made very small. Therefore, the modeling of sound can get rid of some structural constraints.

Opportunity • There is currently a lack of mature visualizations in the market. • Social media platforms do convert aduio signals to visual signals, but this does not easily trigger synesthesia. • As an accessory of mobile phones, smart music speakers have obvious advantages in some fixed scenes such as in yoga rooms.

Weakness

Threat

• For most ordinary users, music visualization does not refer to an experience that goes beyond hearing.

• The market of acoustics equipment is not big, and the market share of big manufacturer is more stable.

• Music visualizations are seen everywhere, but the way of its presentation is important. Some visualization cases that relying on graphic method are not particularly appealing.

• People may have doubts about the new speakers. And the price of products in small quantities will be relatively high, so the price sensitivity of the public to such music speakers could be a potential risk.

WO Strategy

Visualization Emotion

Not only should music be visualized, but it should be visualized in a three-dimensional space, not confined to one dimension.

30

Speaker for music visiualization is supposed to show the emotion of the music rather than reproducing the audio signal in visual way.

Data source: anonymous questionnaire on D1 and C1 proposal, sample size n = 34. A full score of 10 is given for each item.

Improvement strategies After making the prototype, we found that the D1 prototype had the same frame diameter as the C1 and a smaller thickness, but it was visually bloated due to the square design of the base. Therefore, we summarized the advantages and disadvantages of D1 and C1 prototype through the form of the questionnaire, and made a further exploration of C1 scheme.

Apsaras A sustainable worship method Product Design

INTRO In many temples of China, people buy and burn a large amount of incense stickes to worship gods and Buddhas. Everyday, the burning of these sticks brings a lot of solid waste. What's more, the process of producing these sticks often causes health damage to workers.

GOAL To design a method that burning incense can be environmental protection and can also help the people achieve the ritual sense.

Background

One Day Near the Temple...

The incense drying workers waited for several days, but there was no sunny day, so the construction was delayed.

The workers evenly applied the powder to the sticks, but the powder also got into their noses and eyes, which made the workers feel very uncomfortable.

A tourist was holding incense to worship Buddha, but the incense was burned her clothes.

A doctor today saw workers suffering from pneumoconiosis caused by exposure to dust.

The suburban fire department received a fire alarm from the temple, and firefighters rushed to the temple to put out the fire.

Cleaners not only need to clean the incense ash, but also need to sort out the incense that is not fully burned out, so as not to cause a fire.

We need to improve these environmentally unfriendly sacrificial methods and make the production process safer!

Problems: health, waste and worship experience

Air pollution caused by incense burning The burning process inevitably produces a large amount of PM2.5 and PM10. This process also produce more hazardous waste, including various benzene and formaldehyde.

User Journey Map User: Temple visitors

Health issues caused by incense production Workers working in dust-filled environments with little protection and manually shaking the sticks to get the powder evenly applied. All of these behaviors can lead to lung-related health problems.

Deep-rooted culture of worship

Chinese have a strong custom of worshiping and burning incense. The need to obtain psychological comfort through some rituals cannot be realized if the ritual just lasts for a short period of time.

User goal: Incense for gods and Buddhas, get psychological comfort.

Mind Map: create a more sustainable way for worship

System Map

A new form of worship requires both software and hardware. Atomizer is the core component to solve the hidden danger of traditional incense. And social applications are the main way to enhance the sense of ritual.

Compare

The improved system can operate smoothly with minimal resource input and does not pose health risks to stakeholders such as visitors, monks and incense makers. In addition, the new system adds the function of recording wishes and sharing. Regional administrators, such as firemen, can effectively analyse data through an intelligent system behind the scenes and plan future tours based on the data.

Hardware Description

Apsaras produces water vapor through a nebulizer to simulate the effect of traditional incense smoke. The 'incense' is a trigger switch that only works when it is inserted into the 'burner' and generates water vapor. LED beads on the top also simulate the effect of fire.

Cleaner-o A small household sterilizer Product Design

INTRO The COVID-19 pandemic has made ever yone pay attention to hygiene in our daily lives. Disinfecting small household items, such as watches and headphones, has become a new requirement for many spaces.

GOAL Design a sanitary and suitable for everyone to operate disinfection machine.

Scenario Flexible placement Sterilizers can also be hung on walls to save space, but not all Spaces have vertical planes to use.

Prompt Not everyone is interested in disinfection, so the sterilizer must have some prompt functions, such as voice prompt or sound and light prompt.

Control of ozone Disinfectors are designed to disinfect objects that are difficult to clean, so high temperatures and ultraviolet light are reasonable.

Small size Desktop space is often limited, so sterilizers should be as compact as possible to reduce volume.

By studying the scenario we can identify some design elements of the sterilizer.

Grey as the main color. In order to adapt to the desktop space, the color of the sterilizer is best gray, and there are some eye-catching colors as an ornament to remind users to use.
