Controlling Robot Vehicle Using Hand-Gesture with Mid-Air Haptic Feedback

Abstract

In this paper, we improve the usability of hand-gesture control system of robot vehicle using mid-air haptic feedback. The system notifies a user of three states of the system with haptic feedback: (A) the user’s hands exists in a recognition range of the system, (B) the robot vehicle is controllable and (C) the user is controlling the robot vehicle. As a result, haptic feedback improved the usability and the variation of haptic feedback was not perceived completely.
