Overview
Atheria is an AR rehabilitation game solution for hospitals:
medical staff handle setup and in-session guidance, and patients just “play.” It turns tedious therapy into something fun and sustainable, boosting stroke rehab adherence and session completion.

The Problem
Stroke can cause different problems—like pain and functional issues—depending on its type and location. In ischemic stroke, common issues include movement problems, spatial neglect, and mood or thinking changes. Movement problems often show up as weakness, low endurance, and poor control in the affected arm or leg. These issues can make daily activities and independent living harder. The U.S. NINDS says the core of rehab is clear guidance, focused goals, and lots of repeated practice.
Patients generally reflect that traditional repetitive stroke rehabilitation treatment is dull and boring, and it is difficult to maintain interest. However, patients' enthusiasm is often a necessary condition for achieving good clinical efficacy

The Solution
Hospitals can purchase existing ar devices to enable patients to play virtual games for rehabilitation training under the accompaniment of medical staff, thereby enhancing patients' enthusiasm

Overview
The rehab team is well staffed and runs on a clear daily schedule. Spaces are roomy, equipment is modern, and staff guide people step by step. The stroke-related team works closely with rehab: from arrival, through the stay, to after going home, someone follows up so training doesn’t “drop off.” Family members can also learn how to help at home.

Pain Points
After a few sessions it feels dull, and progress isn’t obvious.

Affinity Mapping
By interviewing the daily lives, treatment methods and demands of four stroke patients, I summarized their responses into five major categories.

First Version Prototype
After the interview, I made a low-fidelity design drawing, which was the initial appearance of my project

Usability Testing
For the first version of the design, I made a paper prototype and invited three classmates to test it, recording their feedback

Final Design
After multiple rounds of testing and iteration, we arrived at a streamlined layout that supports fast, flexible, and focused design work.

Accessibility Test
Conducted in-depth development using tools such as Unity and reality composer. Through gesture language, I enabled my design to be draggable for display and used on ar glasses
Through user testing to study whether the current ar game therapy courses are suitable for middle-aged people, thereby further improving the visual effects of the games
What I learned
AI video generation software can quickly produce animations that require a lot of time to make, making it an excellent presentation method for interaction designers.
In the Atheria project, I trained Ai extensively. To ensure a consistent style for each game, I used the parameter “sref” and took a satisfactory image as a style reference.

Meanwhile, when creating the shuttle scene, I can first generate two pictures as the first and last frames, and then let the ai combine them to make the output result more controllable and reduce the randomness of the ai
