Brief
A biofeedback app designed to help those adjust to their new prosthetics
As the only designer, my task was to individually redesign the UI of the prototype of the app. The app was designed as it recognizes the difficulty of navigating the transition to a prosthetic limb can cause significant challenges. Many individuals experience a period of adjustment, during which trust in their new prosthetic may be limited, leading to uneven weight distribution. This app includes various trainings that will help guide the user to place equal pressure on their legs and keep track of their recovery progress
Those with new prosthetics are not necessarily experts in the field of biofeedback, thus navigating a corrective feedback application could be overwhelming and challenging for them
To redesign the application to be accessible to individuals with little to no experience in the biofeedback field
Due to the limitations, I gathered feedback from 3 main sources:
Myself: Looking around the lab, I noticed I was the only one with no experience in the biofeedback field and has never encountered the app before. So decided to put myself into the users’ shoes and see what aspects of the app
Lab Member 1: They have no experience with the app: I conducted a master-apprentice interview with one our recent lab members who was not involved in the development of this application at all
Lab Member 2: They are a core developer of the app and have already gone through multiple walkthroughs of the app. They went through a simple walkthrough of the app again, recalling any troubles they faced
Analyzed the user flow diagram with the collected user feedback on where improvements could be implanted. Organized the feedback gathered by Identified pain points that would possibly needed to be addressed
To understand current UI/UX standards and common uses in health applications, exploratory research was done on mainstream fitness applications and how users would operate through that. Some concept sketches for certain interfaces were created, as well as low fidelity wireframes
Not all designs went smoothly, when I ran into conflict between certain designs I liked to run around the lab asking for my lab members to rank the designs by preference. For example below were a few designs for the past trial summaries
Utilizing Fitt's Law, targets are made big and clear for easy to click buttons. The vertical design also allows for flexibility in adding other user types in the future, just make it scrollable!

The user is forced to start the connection from the left foot, ensuring the sensors attached are in the correct orientation. Additionally, the bluetooth permission is only asked when absolutely necessary, so when the user starts their sensor connection

Slidable bars to allow for efficiency in space and possible additions in the future
Folding of the selections is a way of simplifying complex tasks into steps, this will help reduce the time the user requires to make a decision. Automated quick notes were also added to save the user from typing in their feedback

Scrollable home screen where all features can be found, and a side navigation bar allowing for flexibility of adding in additional features in the future
An expandable calendar that allows for easy access of all past trials by date
