Introduction - Why did I chose the subject? -

- Stroke ↑

- Several rehabilitation game for paralysis of one side of the body

- Vogels! → Start to get interested in stroke patients

- 1/3 Visual disability in stroke patients

Stimulate the boarder between Visual luck area and Visible area

There is new rehabilitation method for Hemianopsia patients by using computer

Medical thesis by Kagoshima University . 2007

Communication Research - Lots of expert’s Help for my project -

Interviews @ Kagoshima university hospital

Play test#1 & Interviews@ Nagao hospital

Helping for finding the patients@ Silverfit

Play test#1 & Interviews@ Kyushu university hospital

Communication Research - Play test and Interviews -

- Play test#1 in Japan

- Idea*1 (Rhythm game) → Failed

- But I learned a lot from the play test and interviews

- The way of stimulation wasn’t correct×Line ○Points

- Too difficult rule for the patients

- Should be more familiar with elderly people

- Can’t handle multiple keyboard

What kind of Game Design is suitable for “Hemianopsia” patients?

1. Eye tracking by webcam

- The game will know where the patients are looking at

- They can play the game without watch by care persons (because patients has to keep their eyes fixed at center of computer)

- The patients can rehabilitate in their own house

What kind of Game Design is suitable for “Hemianopsia” patients?

2. Idea*2 (Fishing game)

- Simple art and Sound(If it is too much, the different parts of nerves will be stimulated )

- Simple rule and One button game

- Correct several kinds of fish and make own aquarium

- Art performance for only feedback screen

A float = stimulation

3. Interface design

Choose one of the 4 locations to place the interface

(Depends on where is the visual disability)
