BACKGROUND

We no�ce a piece of news talking about the difficulty of blind people ordering their meals in a restaurant by chance. The emo�on on their face reflected the lack of accessibility service in the restaurants around them.

Therefore, we decided to design a service that can bring them a kindly experience in ordering food.

RESEARCH PLAN

-What happens to the blind people’s ordering enviroment? We shadowed and interviewed blinds to understand the pain points and opportuni�es. According to the research, the most influen�al problem is not physical embarrassment, but the common psychological worry of "not wan�ng to bother others". This is due to their nega�ve help-seeking experiences before.

Desktop Research ON-SITE Observation

Find the problems of the blind people when ordering Find certain direc�n for further research

We play as blind for a week to put ourselves in their life and try to order food in this period. We found that there are a lot of disobliging services when a blind want to order food.

For example, when blind people are wai�ng for their meals, there is no place for them to await. In that situa�on, they are afraid to block others from ordering or picking up food. There are s�ll other ordering problems that show up in this process.

All in all, we found many ordering problems that plagued users during the as-is journey process. This led us to further interview users to clarify their true feelings.

INTERVIEW

We interviewed two people. One of them is a 20-year-old college student who broke her eye when exercising and living in blind life. Another 43-year-old man who is a na�ve visually impaired person that working in massage store.

College student(20)

Frequently using Uber eat or Foodpanda to order food. Some�me I will cooking by myself if I am free.

2.The most impressive dining experience you have.

Inappropriate alt text

For example, There are 3 icon with different means on the ordering page. But it always call”bo�om” when describing them by the voice mode. That’s why I feel frustrated every�me when making an order.

Service of the Restaurant

Some restaurant didn’t know how to offer the service to blind people.

I o�en feel nervous that I’m not sure if I bothering the restaurant or other customers.

Because of the uncertainty of the service that the restaurant offer, now I prefer to dealing meals with delivery apps.

1.How do you dealing with meals everyday?

Asked employees who are familiar with the surrounding environment in the workplace to help me buying meals.

I avoid going out for food unless someone takes me out to eat.

I would pre-call the restaurant or use uber eat to order food. Some volunteers have willing to bring a meal for us.

2.The most impressive dining experience you have.

Call to

restaurant

Calling speedy and say the point of order to save restaurant’s �me on serving them.

Frequently visited res taurants will more or less remember our needs.

Uber eat

I'm scared that I can't change my order a�er it's been sent.

I won't receive voice no�fica�ons when my meal is delivered.

I will ask my friends to order the food first, and then deliver the food through them a�er the meal is finished.

Medium usability concerns that might frustrate users

Minor usability concerns for users

There are at least 74 ac�ons do not meet the requirments for the blinds .With the research above , We find out the main insight of the issue.

THE MAIN INSIGHT

“The visually impaired people are afraid to buy food outside by themself due to the unconfident environment and unfamiliar situa�on.”

PROBLEM

“How might we encourage the blind not to be afraid to ask for help when ordering food?”

GOALS

Not sure about the surrounding environment around them. Also, they don't know whether ordering food will affect others.

Let the blind not shy away from asking for assistance.

Provide blind people a specific way to ask for help.

T hey don't know what kinds of accessibility services the restaurant offers.

Volunteers can simply reach out to the blind and carry out their specific requests.

T he online ordering system is difficult for some visually impaired people to operate.

Clearly Alterna�ve text to support blind for ge�ng informa�on.

Priori�za�on Grid Big Idea

Like a psychological test, you can know what to eat a�er answering the ques�ons.

You can stay at home and get the food that is cooked.

You can fully understand the contents of the menu without the mind of bothering others.

To allow the blind to order food in a more comfortable environment, we believe that designing an online ordering pla�orm with volunteers to assist the blind will be an aimful solu�on for them.

This online ordering mode is mainly based on the psychological test-like answering mode that can make blind people more intui�vely rely on auditory ordering. Also, we have marked explicitly page content prompts on each page. We add appropriate and clear Alt text to the images that appear. In addi�on, blind people can share their needs with others for assistance in ordering meals.

We redesign the text’s bo�om and contents to meet the pain points. Also, we provided an online matching system to let the volunteer have a way of reaching out to the needy of blinds. Blind people can share their order requests with their friends, they can get the food without making an order by themself a�erward.

BACKGROUND

Rehabilita�on is an integral part of the recovery process for pa�ents with many condi�ons, certainly for those with Anterior Cruciate Ligament Injuries(ACL).

A study published in the Journal of Sports Medicine found that 81% of people who underwent Anterior Cruciate Ligament (ACL) surgery were able to return to sports; however, only 55% returned to their pre-injury level of ac�vity.

Because of this study, we decided to figure out what was causing pa�ents to not recover as expected and look for design solu�ons.

RESEARCH PLAN

-Why many ACL pa�ents can't recover their injuries back to normal?

A�er finding out the issue, we decided to interview pa�ents and physiotherapists to define the concrete factor that influences the recovery process. According to this research, we no�ce that rehabilita�on is an integral part of recovering that the pa�ent has not willing to do on their own.

INTERVIEW

Mr.Liu (36)

We interviewed two people.

One of them is a 23-year-old College student that was got ACL by playing basketball.

Another 36-year-old man is a physiotherapist that working in the rehabilita�on center.

John Wang (23)

To face professional medical knowledge, we choose to seek the help of a physical therapist. We asked what ACL pa�ents have the most difficulty recovering from and what are the do and don'ts when it comes to trea�ng ACL pa�ents.

Mr. Liu said that the key for ACL pa�ents a�er surgery and during treatment is rehabilita�on. The efficiency and situa�on of rehabilita�ng will determine the recovery status of the pa�ent's injured part. And Mr. Liu also said that physical therapists usually judge the pa�ent's recovery status based on the pa�ent's muscle strength and walking posture to judge the pa�ent's current recovery status.

Mr.Liu then helped us find a pa�ent with ACL—John Wang. It also allowed us to understand the real feelings during the treatment of ACL.

SHADOWING

A�er interviewing the pa�ent and the physical therapist, we realized that shadowing is one of the best ways to understand the rehabilita�on process. We observed ACL pa�ents recovering in the hospital and interviewed them a�erward about how they felt.

We found that there are several common points in the rehabili ta�on postures, and the pa�ents' injuries can indeed be improved a�er con�nuous rehabilita�on. For this reason, we decided to incorporate this poten�al rehabilita�on law into our design to improve the convenience of pa�ents' rehabilita�on.

During the interview, we found it would be very inconvenient for the pa�ent to back for rehabilita�on because he was usually busy with work and schoolwork. Some�mes John postpones his rehabilita�ng due to his busy life, and the overall treatment effect is rela�vely poor.

" If I could recover at home, I would not choose to go to the hospital for rehabilita�on. " He said.

We also found that because the �me from injury to healing for ACL pa�ents is rela�vely short, medical equipment is a phased auxiliary product for them, and will hardly be used later. Therefore, the medical equipment they bought piled up at home without using it.

THE MAIN INSIGHT PAIN POINTS

“Pa�ents o�en think that returning to the hospital for rehabilita�on is a troublesome thing. Also, they are not willing to spend money on medical equipment for short-term treatment. Therefore, the efficiency of pa�ent rehabilita�on is affected.”

PROBLEM

“How to help pa�ents improve the efficiency and frequency of rehabilita�on?”

It is inconvenient for me to go back to the hospital for rehabilitation.

GOALS

Allow users to recover any�me, anywhere without going back to the hospital.

Use professional medical services to track the user's recovery status and visualize the pa�ent's recovery status

Use shared services to allow pa�ents to freely rent medical equipment and enjoy low-cost hardware facili�es during treatment.

We don't know how long it will take to rehabilitate to get back to our previous physical condition.

I don't want to wasting money to buy the medical equipment for short-term treatment.

IDEATING SKETCHES

A�er evalua�ng the pain points listed above, we believe that wheelchairs are the best way to achieve the above goals in terms of exis�ng assis�ve products. So we used the wheelchair as a prototype for extended design.

At this stage, we experimented with different styles and shapes.Also, we came up with the service of sharing wheelchairs.

ROUGH MOCKUP MODEL

At this stage, we made a sketch model and a 1:1 model to verify the ra�onality of the shape and the usability of the product. A�er determining the func�on of the product, we also determine the appearance of the product. The modeling at this stage is the main direc�on of subsequent 3D modeling and rendering.

Final Design

Our final design is a shared rehabilita�on wheelchair with a fixed rehabilita�on trajectory. This wheelchair allows pa�ents to do ACL rehabilita�on exercises on the wheelchair, and this wheelchair is equipped with a rehabilita�on detec�on belt to help pa�ents measure muscle recovery and detect the correctness of posture, sending the data back to the physical therapy teacher assessment.

RE-ANGLE

Detected Belt

Pa�ents only need to rent from the hospital to enjoy a complete set of rehabilita�on services, which can achieve the vision of environmental protec�on and money saving for pa�ents. It also makes rehabilita�on easier for them, allowing the recovery of the ACL to complete.

Easily rehabilitation X E ective recover

ACL injuries most commonly occur during sports that involve sudden stops or changes in direction, jumping, and landing. The most important thing after ACL injury happened is that focus on the treatment-rest and rehabilitation exercises. Both of the treatments can help regain strength and stability.

We decided to design a wheelchair named”RE-ANGLE”aimed at ACL injury treatment. RE-ANGLE can let patients do rehabilitation exercises without moving their bodies, and track their recovery status. These can help the patient rebuild their knee more effectively and get well soon.

The healthy detector is under the chair cushion.

In order to send your healthy data to RE-ANGLE, you need to take out the healthy detector, connect the detector and RE-ANGLE with BT.

Install healthy detector on the injury knee, than RE-ANGLE would adjust rehabilitation frequency on the basis of your situation.

Start to doing rehabilitation exercises.

The recovery status can be check on RE-ANGLE APP. User can conplete daliy rehabilitation goals to get well soon. They can also get connection with doctors on APP if they have any questions about rehabilitation.
