iEat

-Help people with Parkinson's disease eat better

Tremor, as an important symptom of Parkinson's disease, can affect the daily behaviors of patients such as eating and reduce their self-care ability. To help people with Parkinson's eat better, a system called iEat is designed. iEat is a system which combines a self-balancing spoon & a bowl with a base that sinks and bulges with the sight. No matter how the user's hand trembles, the spoon head keeps still. Moreover, the indentation at the bottom of the bowl helps to gather food together. With the help of the system, users can eat better.

PROBLEMS

Background Information

Patients experience a loss of dignity and low self-esteem and pain.

Data Analysis

Tremor 84%

Tremor is the most common symptom of Parkinson's disease.

Diskinesia65% Dyskinesia is mainly reflected in starting difficulty,conversion difficulty and slow speed.

Tremor is an important manifestation of Parkinson's disease affecting the motor system, can affect the daily behaviors of patients such as eating and reduce their self-care ability.

Food dropped from shaking spoon will stain the table and cause problems with cleaning.

Disequilibrium75%

Patients often walk unsteadily or fall, especially when turning corners.

Amplitude & frequency of tremors

Low frequency, the specific frequency is between 4Hz and 6Hz. But the amplitude of tremor is high.

Literature Review

Pathological Basis

The main pathological feature of Parkinson's disease is the death of large numbers of DA neurons, which produce dopamine in the brain. Dopamine's job is to activate the motor system. Therefore, due to Parkinson's disease, a large number of DA neurons die, resulting in the loss of dopamine in parts of the brain associated with the motor system, which leads to abnormal behaviors such as tremors.

When tremors occur

Tremors most often occur at rest. In the motion position, the amplitude of tremor will increase, but the frequency is low.

Where tremors occur

Tremors are most often unilateral and gradually develops to include both sides of the body. they mostly occur in the upper limbs, lower limbs and jaw, generally do not affect the head and voice.

RESEARCH

In the field investigation stage, the research method combining user interview and observation method is adopted. In the food study, the method of internet search is adopted.

DESIGN

Concept Narrative

Concept 1

Special designed bowl to help gather food, push food and prevent the plate from being knocked over

Concept 2

Special designed bowl which can move like tumbler to make food gather together

Chosen Concept

Concept 3

Special designed bowl like gyroscope and chopstick with rings to prevent chopstick from falling off

Story Board

Concept 4

Special designed plate which has slope to help food gather together, and the angle of the spoon fits the angle of the corner to scoop up the food in the corner

The self-balancing structure of the spoon makes the spoon head always remain level even when shaking, which solves the core problem of food falling from the shaking spoon. The silicone part makes it easier to scoop up food from the corners of the bowl. Additionally, the indentation at the bottom of the bowl also helps to gather food.

Now it's dinner time. The old signs sadly because she thinks her shaking hands would make the food fall out of the spoon.

The caregiver brings new tableware and food.

The bottom of the bowl changes due to the old's eyesight. The area where the meat lies sinks and the place next to it lifts, which makes it easier for the old to get the meat.

The old's eyes lock a piece of meat in the bowl, and she tries to get it with the spoon.

When trying to transport the food into mouth, the old is surprised that although her hand is still shaking, the spoon's head keeps still so that the food will not be spilt.

The old enjoys her dinner successfully so she is very happy.

Combination of archetype line & holding gesture & contact area

Appearance Design

Use the basic principle of universal joint. The selfbalancing structure takes the middle cross shaft as the core, and two motors drive the spoon head along the X and Y axes respectively.

The offset compensation on the X-axis was not obvious. In Phase 2, a motor that drives the X-axis is placed in the middle of the axis.

Two motors in both directions successfully drive the self-balancing structure to compensate for the offset of the spoon head.

The appearance of the spoon was designed based on the architype line, finger contact area and working prototype.

Phase 1

Phase 2

There should be a clear boundary between the sides of the handle so that the user can feel the directivity of the handle by touching it.

Each side of the handle should be comfortable for the fingers and the form language of the spoon head should be consistent with the handle.

FINAL DESIGN

For self-balancing spoon, inner structure containing motor, control module, battery and the wireless charger module are finished. When shaking, the spoon head always remain level, and the silicon part of the spoon head can help scoop up the food in the corner of the bowl. For the bowl, the inner structure can make base sink and bulge with the sight in order to gather food together.

DIABETES ASSISTANT

In modern society, diabetes rates are skyrocketing. The improvement of household medical instrument can not only effectively help patients with diabetes, but also has an important significance for reducing the burden of the medical and health system.Diabetes Assistant is a system that combines continuous glucometer, insulin pump and diabetes management APP. The system not only effectively monitors blood glucose and predicts blood glucose trends, but also provides passive protection under extreme blood glucose conditions. Moreover, patients can also use APP to restrain and manage their daily behaviors.

Chronic diseases are increasing in modern society. As one of the most common chronic diseases, diabetes is one of the biggest public health problems in the world, bringing heavy global burden to public health and social and economic development.Specifically, about 422 million people worldwide live with diabetes, most of them in low - and middle-income countries, and 1.5 million people die from diabetes directly each year. The number of cases and prevalence of diabetes have steadily increased over the past few decades.

Behavior Pattern Study

Problems & Data Analysis

Physical Problems

Vision loss is the most common physical problem in people with diabetes. The more serious complications generally only occur in people with moderate to severe diabetes.

Psychological Problems

Diabetes distress is the most common psychological problem.

Diabetes disorders include the emotional burden associated with the disease, pressure to self-manage, stress related to social relationships, and fear on complications.

RESEARCH

In the aspect of user research, the research method of persona is adopted. In the study of the glucose meter, the competitor analysis and the study of the measurement position of the glucose meter are applied.

Persona

Competitor Analysis

" I'm terrified of being treated differently when people found out I had diabetes"

Painpoints

-Worry about abnormal fluctuations in blood sugar

-Fear of friends' excessive care or discrimination or even alienation

-Hard to stop eating desserts like cake

-Fear of losing potential jobs

Measurement Position

"I'm afraid of complications but I can't stop myself from eating sweets"

Painpoints

-Not strictly following medical advice on diet or exercise

-Complications such as cardiovascular disease

-Symptoms of excessive thirst and excessive urination

-Difficult to master the operation of the glucose meter

-Poor memory, unable to clearly remember blood sugar value

Measurement position of continuous glucometer and injection site of insulin are investigated in order to determine the position to wear the instrument. Upper arm is chosen to be the measurement position since it is the location for clinical studies, and abdomen is chosen to be the injection site because absorption rate at this place is 100% and absorption is super fast.

DESIGN

Concept - Glucose monitoring and prediction

Continuous Glucose Monitor

The dynamic glucose monitor's sensor probes need to be implanted into the body, but are almost painless. The probe is thin and mainly calculates glucose by collecting tissue fluid.

After the tissue fluid is collected by the sensor, the data is transmitted to the bracelet, which displays the data and sends it to the App and the insulin pump. The insulin pump adjusts the basic injection amount of insulin based on the blood glucose data.

Concept - APP for diabetes

Based on previous studies of patient healthy eating and regular exercise glucose control. Therefore, App is and control bad behaviors.

Psychological Basis

Insulin Pump

The insulin pump can autonomously adjust the amount of insulin injected according to the current measured blood glucose level to avoid the risk of extreme blood glucose.

AI Anomaly Prediction

The prediction of abnormal data can be obtained only by input of blood glucose values continuously monitored by the glucose meter.

Develop microhabits and break without consuming self-control. For habits, the concept uses four psychological models-- transforming unconscious behavior into conscious behavior, delaying gratification, and providing alternative behaviors -- to help slowly correct bad habits with little compulsion.

Wireflow Design

Core Flow

Based on the chosen concept, the wireflow of the app was designed. As for the core flow, there are three main parts in the app, dashboard, advice from doctor and habit forming. For habit forming, it consists of two different parts, good habits forming and bad habits breaking.

Interface Iteration

Phase 1

Interface Final Design

Dashboard

Dashboard shows current data and AI prediction data. AI prediction data is displayed in two modes, visual mode and chart mode.

Color use is not ideal, and information hierarchy is not clear.

The improved interaction mode is beneficial to the differentiation of information levels. However, color scheme is not suitable.

Blue and green are more suitable, but the proportion of key colors is too large.

Good Habits Behavior Control Bad Habits

Glucometer & Insulin Pump Iteration

Based on the concealment and aesthetic consideration, the continuous glucometer is designed as the shape of bracelet. In order not to affect normal life, the insulin pump adopts the thin film pump, and is attached to the skin by using the silicon patch. The shape is as flat and small as possible.

Continuous Glucometer

The bracelet will scratch the skin if the probemoved, so the sensor can be an independent patch or a movable bead.

Insulin Pump

The insulin pump is too thick. Therefore, wearing it is may have influence on daily life, and it is not invisible enough.

Some of the shapes are not simple enough and childish, so they are not suitable for patients of all ages and genders.

The shape is combined with jewelry shapes, so the glucometer has better concealment.

Some of the shapes are not simple enough and random. The last one is chosen because the form is clean and simple.

The form language of it is in consistent with that of the bracelet.

FINAL DESIGN

Tele-VIEW

In recent years, Suzhou museum often faced overcrowding as the number of visitors to museums has increased dramatically. More people with different educational backgrounds choose to visit museums, which makes it challenging for the museum to fulfil its educational function.In order to help visitors of all educational levels to easily see the exhibits and understand the content along with historical context in the crowded pavilion, a system called Tele-VIEW is designed. Tele-View is a system combining a tiny staircase with an AR telescope which helps users see the exhibit from a slightly overhead erspective away from the crowded onlookers, while the telescope's built-in AR system helps add a 3D historical context.

RESEARCH

In the aspect of research, the research method of field research is adopted in order to identify the key problems existing in the Suzhou Meseum West Branch.

Poor Link of Timeline & Statue

The historical axis on the wall and the statues are not at the same place. It is difficult for visitors to clearly recall it when visit statues.

Too Small Introduction Card

The introduction card of each statue is quite small so that it's difficult to read the contents. Moreover, simple text cannot help visitors, especially children, to understand the historical context in which the statue is set. Visitors will still be confused when viewing the statue.

Crowded

With the high volume of visitors and crowded conditions, it is difficult for visitors to see the collection clearly, as it is surrounded by layers of people.

DESIGN

Technology

Concept Narrative

Augmented reality (AR) is used to creat the digital ancient roman scene behind the real statue. In this way, people can see the real exhibit and historical background at the same time.

Chosen Concept

Lift the audience to help viewers to see the real exhibits from above in order to avoid the influence of crowd. And the AR telescope suspended from the ceiling can help users see the digital historical background.

AR Telescope Design

Tiny Stair Design

Evaluation

Shapes of first two concepts are two complex and not clean enough. The third concept is chosen because the form is simple and clean.

Transparent stair is more invisible so that it will not detract from the museum's original interior design. Round shape is safer for people around it and looks more elegant and simple.

Stair

0.1m < Hight of each step < 0.15m

Length of each step ≥ 0.3m

0.22m < Width of each step < 0.28m

Ergonomic & 1:1 Model Testing

Design principles of stair and guardrail were checked. Moreover, 1:1 cardboard prototypes were made for testing the size of the stair and the telescope and the relative position between the two. Through the test, it can be figured out that the hanging point of the telescope should be slightly away from the stair so as not to touch user’s head.

Guardrail

Hight ≥ 0.8m

Designed Stair

Hight of each step is 0.3m

Width of each step is 0.28m

Hight of guardrail is 0.8m

Hight of lifting up is 0.9m

User Journey

The crowd makes it difficult for users to get into the first row to view the statue.

Appearance Iteration

The user decides to use the stair and the AR telescope to view the statue slightly above the crowd.

The user adjusts the height and angle of the telescope to the right position by hand.

The digital background created by AR helps the user understand the history background of statue.

Stair

The details of the staircase, such as rounded corners and materials, are constantly adjusted in the iteration.

FINAL DESIGN

Preface

Nowadays, people are in an era of information explosion. Various social media try their best to deprive people of their attention and instill a large amount of information into people's brains. However, most information online are redundant and useless. As a result, there is a contradiction between people's limited attention and too much invalid information.

This design explores the negative impact of information overload on people and the hidden truth behind it -- MANIPULATION, and uses interactive devices and interfaces to help people reflect on the phenomenon of information overload, so as to alert people.

INFORMATION OVERLOAD

RESEARCH

Information Addiction

Information overload will lead to changes in the brain's frontal striatum circuit and dopaminergic system, and the formation of new neural circuit connections will desire to be activated all the time, leading to addiction to information.

Blind Confidence

The convenience of the Internet makes it hard for people to distinguish between the information stored online and the information stored in brain, which leads to blind confidence and the false belief that they possess a high level of knowledge.

Mental Problem

Reduced Concentration

Attention depends on working memory, and the influx of multimodal information can affect working memory and negatively affect brain regions involved in attention, making it difficult to concentrate for long periods of time.

Brain Damage

Prejudice

The mechanism of big data and personalized recommendation can cause users' bias towards certain events and echo chamber.

Lack of Deep Thinking

The visual, tactile and auditory cortices of the brain have all been strongly stimulated by the flood of information on the Internet, leading to a gradual weakening of neurons and connections associated with deep thinking.

Damage

Memory Loss

The Internet has become the latest interactive memory storage system. People who are used to searching on the Internet are more likely to remember the location of information rather than the content.

Information Processing

Mixed Information

Information on the Internet is mixed, including a lot of false and misleading information. People have difficulty distinguishing real information from fake information.

Manipulated by Information

Much information on the Internet is manipulative. For example, some advertisements induce consumption and some information to control public opinion.

DESIGN

Concept Narrative

In view of the harm of information overload, different concepts are came up with to make people understand the harm of information overload, so as to guard against and reflect on this phenomenon.

Concept 1

Tell the participant that the end of the aisle is the information he needs to get. As participants walked down the aisle, "hands" stretched out pull and block their progress, simulating the attention drawn by invalid information on the Internet.

Concept 4

Processing information is visualized. In the Internet era, people are trapped in a square box full of information in all directions, and the swivel chair keeps turning in all directions. People become slaves of endless information, which triggers people's reflection.

Evaluation

Chosen concept can help people get a strong sense of immersion by switching roles and perspectives, and deeply realize the dark truth behind information overload and its fearfulness, thus playing a role of warning. That is why it is chosen.

Concept 2

Two boxes represent the thinking ability of people in different times. Each box has an observation hole. People will see different scenes in two boxes, impliying that people's thoughts and vision in the Internet era have gradually become one-sided and superficial.

Concept

The concept likens the whole process of pulling down a screen to refresh and get new information to using a slot machine, which is addictive. It also suggests that the pleasure of acquiring new information comes at expense of focus, attention and time.

Concept 3

The car symbolizes attention. Roadside billboards attracts implying that irrelevant information will attract attention. The user feels a force coming from the steering wheel in the opposite direction and needs fight it to keep the on track.

Concept 6

Compare information delivery to the process of delivering food conveyor belt. The in printing age is like good steak, and the phone in Internet age like junk food. Although information intake bring cheap pleasure the quality cannot guaranteed.

Act 2

Manipulator pushes information to manipulate ordinary web surfer

Observer observes all these Act 3

The concept involves role-playing. The user first experience the identity of ordinary web surfer, browsing the web as usual. Then enter the role of the manipulator, using information to control the ordinary Internet users. Finally enter the identity of the observer, from the perspective of the observer to witness the manipulation of ordinary people. Experience the dark truth behind information overload and its horrors through the shift and contrast of perspective.

As the ordinary web surfer, the user searches for some information on the search engine. At the same time, the user who acquired the identity of the manipulator uses some psychological models to push information and manipulate ordinary web surfer. As the role of observer, the user understand the manipulation behind each information online.

Interfaces for the are designed and and users are invited can understand interface and feel manipulating and by using information.
