To me, what is design? I strongly believe that design is not only about problem-solving, but it must also create some value or social impact that can help shape the future lifestyle. In my latest projects, I have tried some topics with social concerns and focus on design research process for human-centered design. I always put a lot of effort into user research to discover not only pain points but also potential needs, and try to find out integrated solutions from various viewpoints.

â€œHow to offer incentive for stroke patients to keep doing rehabilitation?
Demo film on Vimeo: vimeo.com/312531413
Providing a optimised rehabilitation journey for stroke patients. The journey of rehabilitation is often long, slow and exhausting for patients, therapists and caretakers. It is always hard for patients to keep doing rehabilitation after a stroke although it is the only way for them to maximize their recovery. RE+ is an innovative hand rehabilitation device for stroke patients which applies the concept of gamification and group therapy to eliminate the exhaustion of the rehabilitation journey and enhance the incentive of rehabilitation.
Rehabilitation System RE+ is a two-fold design concept: a wearable hand movement sensor device and a game software that syncs to the device, which allows stroke patients to use the device to control the game. The games in the software are all designed for the specific movement for rehabilitation, guiding patients to conduct the rehabilitation exercise in a gamified method.
controller Belt Fixing userâ€™s hand
Sense finger strength
Supporting userâ€™s hand
Foundation Arduino board inserted
Releasing muscle tightness aftera stroke The wearable sensor device can sense the position and strength of patientâ€™s hand by several sensors inserted inside the device under the silicone supporter. By conducting the hand movements guided by the game software, patients can train their muscles of fingers, carpal and arm, which helps them release the muscle tightness following a stroke. The soft silicone rubber supporter with an ergonomic shape makes it more comfortable for patients to use for a long time since a rehabilitation process might takes up to several hours.
software The RE+ system is accompanied by a collocated game software with a variety of games designed for the particular hand movement of stroke patients. We have selected several games that is fit for the hand rehabilitation and also easy to learned by elderly. The games includes drawing game, mirror game, tic tac toe, gomoku and denryu iraira bo, which are devided into different difficulty level. The creative or competitive game gives patients the empowerment of creativity and sense of accomplishment, improving the feedback of rehabilitation.

Personal record: log in by account The software requires patients to log into his/her own account before starting the game. The performance history can be recorded in the account of each patient, which is easier for therapists to measure the recovery level of each patient, and group patients with homogeneity to conduct the group therapy function, a function that will be introduced in the next page.
Group therapy: mutiplayer mode In physical therapy, the physiotherapist will select patients with homogeneity to do rehabilitation together, aiming to reach the social facilitation effect which can make patients perform better. Thus, the game software applies the group therapy concept, providing a multiplayer mode that allows several patients or even caretakers to join the rehabilitation together. For patients, the social facilitation effect would not only make the rehabilitation journey more interesting and interactive, but also stimulate their performance on rehabilitation. Moreover, when the caretakers also join the rehabilitation, it would increase caretakersâ€™ engagement in the patientsâ€™ rehabilitation journey, which would also improve the relationship between them.
BACKGROUND RESEARCH STROKE - Brain hypoxia Stroke is a medical condition in which poor blood flow to the brain results in cell death. A common cause of stroke is a blood clot that forms in a brain blood vessel. A stroke causes damage to the brain, and the symptoms depend on the area of the brain affected. The more extensive the area of the brain affected, the more functions that are likely to be lost.
COMMON SYMPTOMS OF STROKE PATIENTS
- One-side body weakness - Balance & co-ordination problems - Numbness
- Swallowing problem - Speech and communication - Vision difficulty
- Mental processes difficulties - Inappropriate emotions - Tiredness and despair

DEFINING PROBLEM â€œWhy it is hard for stroke patients to keep doing rehabilitation?â€? Rehabilitaion is the most important part in the stroke treatment. It is almost the only way for patients to recover and maximize their quality of life after a stroke. However, many patients cannot keep doing rehabilitaion in the chronic period.
REASON 1: Diminishing utility of rehabilitation Most return of function is seen in the first few months, and then improvement falls off with the 6-month "golden window" considered officially by U.S. state rehabilitation units and others to be closed after six months, with little chance of further improvement.
However, complete recovery is unusual but not impossible that daily rehabilitation exercises should still continue. recovery level (%) ristriction of recovery level (depends on how serious the brain was damaged)

JOURNEY MAP of stroke rehabilitation
Can‘t decide for myself and is taken by my family to rehabilitate. Can‘t do any motion with my site of onset so the therapist helps me.
For few days, with frequent rehabilitation, partially recovering. Obvious progress makes me conﬁdent. :|
Gradually, I can move on my own. I believe that rehabilitation will help me recover. My family and I look forward to taking care of myself in the future. Discharge from hospital. :)
In order to recover quickly, I actively rehabilitate. For some months, I don’t noticeably strengthen.
Repetition makes me feel tired and bored. Begin to doubt the eﬀectiveness of the rehabilitation. :|
I don’t want to spent much time in which is invalid. My family and I tried to catch the last hope. However, we feel more and more depressed. I become lazy.
I lost my motivation and even start to regress.
- Too anticipative to achieve immediately - Too boring and tired to do for long time - Too depressed so that lost motivation
Patients (in the chronic period) do not want to keep rehabilitation.
Solution: To oďŹ€er incentive!
Stroke patients who are able to move his/her site of onset in the chronic period
Keep doing the rehabilitation exercises
They can do these motion and not feel really tired, but repeating same thing makes them boring and gives no accomplishment
DEVELOPING IDEAS “How to offer incentive to do the rehabilitation?” What if... Traditional rehabilitation (boring / Frustrating)
GAMIFICATION - Improving user engagement Gamification is the application of game-design elements and game principles in non-game contexts. Gamification commonly employs game design elements to improve user engagement, organizational productivity, flow, learning, and more. A collection of research on gamification shows that a majority of studies on gamification find it has positive effects on individuals.

Social Influence & Relatedness (friending)
GROUP THERAPY - Increasing interactivity by social facilitation In psychology, social facilitation can be defined as the tendency for people to perform better on simple or well-rehearsed tasks when in the presence of others than when alone. This effect is applied in physical therapy. The physiotherapist will select patients with homogeneity to do rehabilitation together. For each patient, the presence of other patients serves as a source of arousal, and heightened arousal increases the likelihood of the patients to do better on the tasks.

Motivate patients to do rehabilitation exercises
Our idea: Gamified hand rehabilitation device Flat hand-rehabilitation combines with games to increases the challenges and interest. Also, it can enhance the interaction with other patients, so it will increase the motivation to rehabilitate.

SHAIR Transformable stadium seats
Natural disasters has been a nightmare for Taiwanese people for long. Through this project, my teammates and I tryed to find out a solution to decrease the impact or harm caused by natural disasters for Taiwan from different aspects. During the design process, we have put a lot of efforts to make the design more simple. We wanted to create a little simple change to existing products and enable them to exist normally but come in handy when natural disaster happens.

â€œCan we give consideration to QoL in disaster shelters?
Providing a better environment inside evacuation shelters.
SHAIR is a stadium auditorium seat which can be transformed into a modularized living space for refugees when the stadium becomes an emergency shelter for disasters. It is composed of modular units and simple tenons that can be easily collapsed and assembled. SHAIR can create a private living space which provides refugees a higher living quality and larger personal space during the hard times inside the shelter.
SHAIR Transformable stadium seats
Modularized components The chair is composed of modularized components: two connected pads fixed on the bleacher and a shell fixed on the pads. When the stadium becomes a shelter, the shell can be simply taken down from the pad, and it can have some assemble type with the latch on the pad.
插孔 jack 45cm
latch on each side
Assembly There are special tenons, latches and jacks on the side of the pads and the shell. The tenons allow the shell to be fixed on the pads when the stadium is for normal use, and to be assembled with the pads after it is taken off from them when the stadium becomes a shelter. The several assembly types allow us to create a modularized living space for refugees.
WHEN A STADIUM BECOMES A SHELTER
Demo film online: vimeo.com/335621490
Dismantling procedure: easy to conduct but not easy to discover We have designed a special dismantling procedure by the tenons, which is for staffs in the shelter, who know about the procedure, to take off the shell easily, but hard for normal people to find out the procedure. This is to prevent the shell from being easily taken off by crazy audiences when the stadium is as its normal use (having a ball game).
Assembly I: Cubicle Wall
Assembly II: Visor / Table
Match the hole on the side of the shell and the red latch on one of the pad, and it can be used as a cubicle wall for the refugees in order to separate their living space.
Clutch the trench on the shell to the edge of one of the pads and we can get a barrier above used as a visor for the bunk. Whatâ€™s more, the flat area on top can be served as a table for dining or other uses.
And the bleacher will be transformed into modularized living spaces.
Modularized Living Space For Refugees A single bunk is constructed by 8 chairs in total, including 4 on the upper row and another 4 below. The cubicle walls can also be re-assembled and turn into simple tables. This makes the life in the shelter become more convenient and improves privacy for the refugees.

pads Protecting refugees from moisture of concrete floor.
Easier To Set Up / Clean Up With SHAIR applicated in the stadium, it would be easier to set up for a shelter by simply transforming the auditorium seats into living spaces, instead of preparing great amount of material resources. After the emergency evacuation, the environment can be easily cleaned up by putting the seats back to their original position.
Better QoL Inside The Shelter The modularized living space created by SHAIR not only gives consideration to space, privacy and flexibility, but also protects refugees from moisture of concrete floor by the pads below since the weather in Taiwan is usually moist. It can create better QoL inside the shelter for the refugees.
More Efficient Space Usage If the resting area of refugees is moved onto the bleacher (auditorium seats area) from the ground, the space would become larger. Moreover, since the ground space is cleared, it can be used to store relief goods or be used as medical center, special care area, activity area, etc. In this situation, the staffs working on 1st floor would not disturb the refugees resting on 2nd floor (bleacher).

DESIGN BACKGROUND Taiwan: one of the most fragile country Under threat of multiple natural disasters, Taiwan has been appraised as top 10 most vulnerable country in the world by S&P. Once a natural disaster occurs in Taiwan, it will not only result in gigantic financial losses and human injuries, but also lead to great amount of victims being homeless. The victims must be evacuated from dangerous area, and then be assigned to shelters nearby.
Nightmare inside emergency shelters Shelters are overloaded due to great amount of people that flock into the spaces. The average living space per refugee will be gravely compressed. It ends up with refugees losing their most primary right of privacy. Under this extreme environment, the refugees could not get enough rest, and their stress will also increase by the time they’ve gone through in the shelter. On top of those, the process of setting up the shelter is pretty exhausting. It also consumes a lot of man power and material resources.
“crowd, chaotic, lack of privacy and security”
BACKGROUND RESEARCH Professional consultation: NCDR In order to get deeper understanding of the emergency evacuation system in Taiwan and know about problems that would happen inside emergency shelters, we have cunsulted with specialist Prof. Chuang Ming-Ren from National Science and Technology Center for Disaster Reduction (NCDR).
Insight: SOP varies from different disasters According to the emergency evacuation SOP in Taiwan, there are specific responses to different kinds of disasters. Typhoons or flood usually cause less refugees, and the evacuation duration is shorter. As a result, local hotels have the capacity to accept the refugees and there is no need to launch a shelter. However, earthquakes often cause more refugees, and the evacuation duration can usually be longer than two weeks. To settle the refugees and also take square footage and seismic coefficient into account, it would usually launch a shelter in local stadium.
Duration of evacuation
Amount of Refugees
short (3~5 days)
short (<2 weeks)
long (>2 weeks)
(dozens / hundreds)
(dozens / hundreds)
(hundreds / thousands)
DEFINING PROBLEM From the consultation, we realized that only when earthquake happens will it need to launch an emergency shelter in a stadium. To find out what problem would happen inside the shelter, we have make a journey map of emergency evacuation to search for pain points and design opportunity points.

In fact, the capacity of temporary sheltering in Taiwan does not meet the needs. If a great earthquake hits Taiwan, shelters will be overloaded and the space per refugee in the shelter will be against regulation. Under this orderless circumstances, refugees surely will gone through more stress and anxieties.
Despite the problems such as orderless and crowded space, another one is that refugees have no privacy in the shelter. Moreover, while the volunteers and staffs are walking around, they will also disturb the refugees. In this situation, refugees cannot get enough rest and will be totally stressed out.
Great amount of resources, such as bed frame, will be needed when a stadium is running as a shelter that can accommodate dozens of refugees. It may takes up to 24 hours to settle everything up. In this situation, refugees can not move into shelters immediately. It is also a big trouble to set up or clean up the shelter.
DESIGN GOAL According to previous studies, we can know that the biggest problems are: space insufficiency, privacy issue, and the trouble with setting up the shelter. That is when a thought came through our mind—what if we can come up with a solution to help speed up the process when opening a shelter, meanwhile make sure that each refugees can get enough living space, and improve quality of live and privacy at the same time?
“local material + easy setting up + QoL”
WHY NOT MAKE USE OF BLEACHERS?
The bleacher (seating area) accounts for much space in the stadium. The sheltering capacity will be highly increased if we bring the space to use. As a result, we came up with an idea to move refugees from the floor onto the bleacher, and redesign the chairs on the bleachers that can be easily and quickly transformed into living spaces for refugees when the stadium becomes a shelter. With the wide area on the bleacher and great amount of seats, it can provide a lot of modularized living spaces for refugees. Also, the shape of the stairs may be used as barriers to block visual cues.
FIELD STUDY To ensure design feasibility, we did some research about the building act of stadiums, and went to some stadiums to conduct bodystorming. Based on our research, we found out that there are specific regulations about the spacification of bleachers or auditorium areas in a stadium. Therefore, we can make sure that our design on the stadium seats can reach to the expected functions under restrictions and can be compatible to different kind of stadiums.

Convex Hair dryer with large air volume
This is a project applied lean product development (LPD) method to improve the customer satisfaction of a budget hair dryer product. Different from my other works, my teammate and I focused more on the R&D process and market evaluation in this project. In the research process, we have applied some knowledges about both engineering and management, and we have tried to think in a more pratical way to make this project closer to the real commercial world.
This project was exhibited at 2018 Lean Enterprise China annual global summit as a demonstration project.

Our hair dryer is now in a mass production schedule by Keyarrow (Taiwan) Co., Ltd.
The purpose of product development is to design new products that improve the lives of customers. As a result, how to identify customer value precisely and create solutions in a short period development cycle is the main challenge for companies in a competitive market. Lean product development (LPD) is a pratical method for companies to face the challenge, helping them to satisfy their customer value, reduce development cost and shorten the development cycle time. It has been claimed to increase innovation ten-fold and increase introduction of new products 400%-500%
Knowing the customer values, putting what they want into their hands.
LEAN PRODUCT DEVELOPMENT Lean product development (LPD) is a lean approach to meet the challenges of product development, aiming to reduce long development cycle times and costs. The concept of LPD was first developed by Toyota, which started its lean product development journey at Toyota Loom Works. Maximizing customer value is a core principle in LPD, but the value definitions used tend to be based on logical reasoning rather than real life observations. Feedback on the decision to design a certain feature will not be received until the product is in the hands of the customer. This means that decisions are made on short-cycle experimentation, prototyping, set-based design, and emergent practice. In this project, we have applied a LPD progress presented by Inagaki Kimio, a Japanese LPD leading expert, to develop a more efficient budget hair dryer.

IDENTIFYING CUSTOMER VALUE OF A BUDGET HAIR DRYER
APPROACH We conducted two progress to identify the customer value of a budget hair dryer: thinking aloud test and interview.
Proton PDR-01 NT$299 (about USD$10)
10 participants that “usually use hair dryer after showering”
-2 heat/speed settings -Warm shot
51 Age range
THINKING ALOUD TEST & INTERVIEW We asked test participants to use the product while continuously verbalizing their thoughts as they move through the interface.
INTERVIEW PROCESS Like? Expectation?
Conducting thinking alould test
Inconvenience? Unsatisfaction? How to improve?
We devided the outcomes of thinking aloud test and interview into several categories.
Form and aesthetic
Adjustable ar temperature Enough air volume
Appropriate air temperature
No smelly airflow Different air outlet choices
FORM AND FETURES
Simpler switch icon Easily-taking-up cable Comfortable handle Smaller size Lighter in weight Prettier
Less noise Fast drying Hair care and styling
OUTCOMES RANKING For every expected outcome, we conduct a survey, asking our test participants to give a satisfaction score and an importance score. Then we drew a figure showing the scores of each outcomes. Survey Outcome
A No smelly air B Form aethetic
C Air volume
D Hair care and styling
F Easily-taking-up cable G Comfortable handle
H Less noise
J Fast drying
Important but not satisﬁed (I>6／S<6)
E Adjustable air temp.
I Simpler switch icon
K I J C
K Appropriate air temp. L Lighter weight M Undisturbing cable
N Smaller size O Outlet shape
Those outcomes marked as “important but not satisfied” are obviously the point we need to improve (arranged in priority order): 1. air smell 2. form aethetic 3. air volume 4. hair care and styling
5. air temp. adjustment 6. easily-taking-up cable 7. comfortable handle 8. noise
DEFINE OUR COMPETITORS We choosed several product of similar prices and wattage as our competitors. Comparing their features below: Brand
Wind Form Wind Styling cable smell aethetic volume & caring take-up
Size／Air volume／Temp. adjust
Low ES／Airflow concentrating
We can see that most of the firms generally claim that their products have large wind volume and adjustable temperature. Those two features are the main competitive strategy on the market. On the other hand, we can also mark the customer values that most products on the market cannot satisfiy. Notably: wind smell, wind volume, taking-up cable, form aethetic, and noise.
OUR STRATEGY PRODUCT POSITION Budget price and lower performance requirement relatively
Comparing the customer values and the competitor analysis, we can define the values which customers think important but not satisfied by most products on the market, including wind smell, wind volume, taking-up cable, form aethetic and noise.
MARKET POSITION Medium to low income Lower requirements (Students / housewives / elderly)
Our goal is to improve these parts to make our product become more competitive on the market.
FINDING TRADE-OFF POINT & FINALIZING ON DESIGN STRATEGY
CAUSAL MAPPING We made a causal map to visualize the links between different design parameters of a hair dryer. By the causal map, we can clearly understand the trade-off reletionship between parameters and what obstacle we are facing.
Fan shape Inlet shape
+ Inlet size
TRADE-OFF POINT The obstacles we face are the parameters which are bounded by each other. That is the trade-off point of the design parameters. We have two choice to deal with the problem: to choose which side we should be or to try to break the trade-off relationship. Priority

FINDING TECHNICAL SOLUTION ANALOGICAL THINKING According to the opportunity value analysis, the point we need to improve first is the wind volume. As a result, we tried to use analogical thinking method to develop technical solutions. After we did some research in fluid mechanics and consulted with some expert for the airflow problem, we learned a simple effect that can influence the flow of fluid Coanda effect.
COANDA EFFECT The Coanda effect is the tendency of a fluid jet to stay attached to a convex surface. As described by the eponymous Henri Coand in different patents: "the tendency of a jet of fluid emerging from an orifice to follow an adjacent flat or curved surface and to entrain fluid from the surroundings so that a region of lower pressure develops." The pressure effect, which is usually not indicated, is fundamental for the comprehension of the Coand effect. ďź?Wikipedia The Coanda effect has many kinds of applications, and the most common one is the wing of aircraft that extra lift coefficient can be caused by the Coanda effect.
Diagrams illustrating Coanda effect
SHORT-CYCLE EXPERIMENTATION In LPD, a core principle is that decisions are always made on short-cycle experimentation, prototyping, set-based design, and emergent practice. It is to ensure that designers can verify their hypothesis before the product is in the hands of the customer. As a result, we have conducted a simple and low-cost experimentation to verify that Coanda surface can work on a hair dryer to enlarge wind volume.
COANDA SURFACE TEST As we have known that applying a Coanda surface to the wind outlet may suck the surrounding air to the flow and make the wind volume larger, we conducted an easy experiment to test if the idea can surely work and which kind of coanda surface we should apply.
Use a hair dryer applied with each simulated wind outlet (5 types: A-D and none) to dry a piece of tissue and calculate the time spent each time.

Because only the lower half of tissue is wet, we stop timing when the color of the lower half is the same as the dry upper half.

Balance Acrylic light design
This is a lighting design concept proposed during my 2017 internship in Xcellent Design, Taipei. Xcellent Design is a Taipei-based lighting and furniture company. Acrylic light is the main product of Xcellent. The core technic of Xcellent is the triac dimming technology which can make light refract softly through the acrylic, creating a comfortable lighting atmosphere.
I tried to make use of the material characteristic of acrylic and the variation of LED lights to create a light with a unique form.
XCELLENTâ€™S LIGHT GUIDE TECHNOLOGY The light guide technology is to apply the triac dimming technology to the acrylic light guide boards that refracts the light softly through the acrylic, creating a comfortable lighting atmosphere.
BENDABLE ACRYLIC BOARD This time, I tried to make use of the bendable characteristic of the acrylic light guide, making a silk-like lamp that intergrates with fluent shape.
INSPIRATION: BALANCE When the masses on the two sides of a balance are equal, they will achieve static equilibrium. At the same time, it gives a feeling of calm, harmony and relaxation. I want to apply the concept of a balance to create a lamp that can also achieve the feeling of static equilibrium by its special weight configuration.
Balance Lighting design
Streamline form and fluent shape Integrate perfectly into modern interior Add a sense of elegance to environment Create exquisite lighting experience
equal weight on both side
Searching for more inspiration In order to discover more inspiration for design, I have tried to conduct some side projects about digital art that are different from traditional 2D and 3D design. I believe that inspiration and creativity come from continuously discovering knowledges in various field. Combining wide range of knowledges into design projects is the future goal and challenge for me.

This is a data visualization project using Processing. This is my first try about programming and media art that I want to search for some inspiration for design in the future. In this project, I tried to process a great amount of flight on-time performance data into a graphic outcome that can show the relationships between parameters and reveal some fun facts about the data.
VISUALIZING FLIGHT DELAY PROBLEM IN CHINA
â€œIs the distance between two cities really as we think?â€? If we consider the delay factor during the journey, the distance between two cities may become farther than expected. In fact, the flight on-time performance in China is relatively worse than in the world. The flight delay problem is even more serious in big airports including Beijing, Shanghai, etc. Take a flight from Beijing to Shanghai for example, the flight duration could usually be delayed to 3 or 4 hours although the estimated travelling time was only 2 hours. Since then, can we still say that the distance between Beijing to Shanghai is still only 2 hours long? This project is to visualize the flight delay problem in China. I have collected the on-time performance data of flights from Beijing to Shanghai within 1 week, and visualize the data on a graph to show the difference between ideal travelling time and the real situation. This project also provides some different kinds of data analysis including the relationship between the delay situation and airline or departure time, which can be a reference for traveler before planning a trip.
COLLECTING FLIGHT DATA I collected the flight data from flightradar24.com, an internet-based service showing real-time commercial flight information. I recorded information including STD, STA, ATD, ATA and airline for the 400+ flights from Beijing to Shanghai within 3/25~31 2018. After collecting the data, I used excel to convert the data into a form that can be read by my Processing code.
PROCESSING THE DATA I created a Processing program to process the data. The code can read the excel file and use the data in the file as parameters to draw a special graph.
PRESENTING THE DATA To present the delay time by distance? We know that the distance between Beijing and Shanghai is about 600 miles with a flight time of 2 hours. However, if a flight is delayed to 4 hours, can we say that it seems like the distance between the two cities has become twice since the flight has travelled twice the time?
Example: Air China 1501 from PEK to SHA with 31 mins delay Date
25 MAR 2019
Beijing An on-time flight
distace travelled more?? Beijing
A delayed flight
original departure time
actual departure time
I tried to present the delay time by the simulated distance travelled more caused by the delay, and draw the data of each flight into a bar. By the length of the bar that is out of the actual distance, we can know that how long the flight was delayed.
If we arrange each bar, or each flight data, by time, we can clearly see the on-time performance on different time point.

GRAPHIC OUTCOME I changed the arrage of time into a round shape that is easier for audiences to compare different time point in a day. The graphic shows the on-time performance in a day that it is an overlay of 7-day data. From the graphic , we can see that the on-time performance in the morning and afternnon is reletively good while the performance become worse in the evening and at night. As a result, the distance between Beijing and Shanghai seems to become longer in the evening and at night. For audiences to check out different layers of this graphic to see the relationship between on-time performance and different parameters including dates and airlines, I have created an interface for audiences to check out by different layers of this data graphic that would be introduced in the following pages.

ANIMATE THE DATA To let audiences know how the graphic outcome was generated by the data and the code, I created a special function that if we click the start button, it will start an animation showing the animated data that help explain how each flight data is drawn as a curved trajectory and what time point the points would change color.
Check by airline (Air China)
INFORMATION REVEALING The interface also allows audiences to chenk the data by different parameters. Audiences can see the on-time performance on each day and the difference between airlines. It can be a reference for travelers before planning a trip.
Check by date (3/27)
The next step Although my definition of design is continuously changing, the one thing never changes is that I believe design must create some value and social impact to make a positive difference in the world. Although we have repeatedly taught that design is a kind of science and a logical reasoning process, I still believe that emotion is the key ingredient to build up connections between objects and people. Therefore, my future plan about design is to focus on the research of peopleâ€™s emotional feelings and intuition toward an object. I have joined my professorâ€™s lab which focuses on cognitive and Kansei (emotional) experience design. I will try to discover design in a psychology viewpoint to see how peopleâ€™s emotion works in the building up process of their cognition about objects, and implement the idea to create products that can truly touch people.
