An IMU-based Wearable System for Automatic Pointing during Presentations

Image Processing and Communications Journal, Vol. 21, Issue 2, 2017-04-04, pp. 7-18.

Abstract: Wearable motion capture systems based on MEMS IMUs are considered a promising low-cost technology that evolves rapidly over the last few years. In this paper we present a wearable pointing device developed with a pair of inertial measurement units that consist of acceleration and angular velocity sensors. Each IMU is equipped with Bluetooth connectivity and the pair is mounted on the user’s arm. Our system provides pointing on screen functionality by capturing the arm’s rotational movement. We present the system’s design and evaluation along with a training method for estimating the user-screen distance and relative position. Experimental results show promising pointing accuracy and precision in a variety of different display sizes and distances making our system an effective solution for on-screen pointing.
