A System Modeling Based Anti-Shake Technique for Mobile Display

Abstract

Mobile devices may cause adverse impacts on our vision due to handheld shake and vibration. In this work, we implement an anti-shake mechanism for mobile display to provide users with a comfortable interaction experience and to minimize negative side effects of screen vibrations. The overall process includes analyzing the accelerometer data, predicting the magnitude of device displacement, and adjusting the position of the display area. The model we propose for motion prediction is based on system modeling. Through recursive least-squares estimation, we can trace the vibration at real time and thus compensate for the handheld shake. We verified this model with tumbling E eye exams and subjective 10-point scale questionnaires. The experimental results reveal that the anti-shake mechanism successfully decreases sight fatigue when applied to mobile devices used in moving environments.
