Development of Control Assistant System for Robotic Wheelchair

English / Japanese

Abstract:

We are developing a control assistant system for a robotic wheelchair. This system detects the head pose and gaze direction of the user and recognizes a self-position and surrounding environment using sensors and a map. Based on the detection of both the gaze direction and the position within the map, the robotic wheelchair can estimate the user's fixation from the position where the user is paying attention. We adopt an attention representation based on histogram. The frequency of fixation is represented by an "attention histogram". Experimental results indicate the validity of the control assistance using the estimation of user's attention.
