A brain-controlled wheelchair based on P300 and path guidance

Abstract

This paper presents the first working prototype of a brain controlled wheelchair able to navigate inside a typical office or hospital environment. This Brain Controlled Wheelchair (BCW) is based on a slow but safe P300 interface. To circumvent the problem caused by the low information rate of the EEG signal, we propose a motion guidance strategy providing safe and efficient control without complex sensors or sensor processing. Experiments demonstrated that healthy subjects could safely control the wheelchair in an office like environment, without any training.
