Evaluation of sensors for inputting data in exergames for the elderly.

We aim to solve which off-the-shelf motion sensor device is the most suitable for extensive usage in PC open-source exergames for the elderly. To solve this problem, we studied the specifications of the market-available sensors to reduce the initial, broad set of sensors to only two candidates: the Nintendo Wii controllers and the Microsoft© Kinect™ camera. The capabilities of these two are tested with a demo implementation. We take into account both the accuracy in the movement-detection of the sensors, and the software-related issues. Our outcome indicates that the Microsoft© Kinect™ camera is the option that currently provides the best solution for our purpose. This study can be helpful for researchers to choose the device that suits their project needs better, removing the sensor-choosing task time from their schedule.
