The use of apps on hand-held devices has the potential to offer advancements in controlling many devices with an intuitive user interface, including power wheelchair control. Many powered wheelchair users require special adaptations to their control interface in order to drive the chair. This paper presents the development and testing of an Android based control system for a powered wheelchair. The control system utilizes the Android device’s sensors to control the wheelchair. The device can be attached to various parts of the user’s body which the user can move to control the wheelchair. The accelerometers in the device are used to drive the chair using Bluetooth technology connected to the wheelchair’s control system. Subject testing was performed with the user holding the Android device in their hand while they performed a variety of structured tasks. These series of tasks were duplicated while the Android device was attached to their hat and again when strapped to the upper left arm. The results from the collected data on specific metrics were compared against similar data when the wheelchair is controlled using a standard wheelchair joystick.
