Space Race is a low-cost and easily accessible game that trains posture control and core strength. It is designed specifically for cerebral palsy patients, but can be used by anybody with access to a smartphone and computer. Rather than relying on complex mechatronic systems, SpaceRace uses the motion sensing capabilities in smartphones as a controller. The phone is attached to the player through a harness, which are available for around $20. The goal of the game is to collect collectables in different levels by steering a fox through tilt and lean movements.

Code Structure

• The Unity development directory was used for game development.
• The server directory was used to develop a local webserver that delivers sensor data to the Unity client and hosts a controler UI on the smartphone.

Documentation

Throughout our code we have endeavored to leave useful comments where suitable. In addition, the whole project is including background, aims and clinical relevance are discussed in the project report.

System Overview

The Unity and mobile phone are both clients to a locally hosted webserver, as shown in the figure below. Sensor data informs both a mobile UI on the phone controller as well as the actual game.
