System modeling based Anti-Shake mechanism for mobile display

Mobile computing devices facilitate our daily lives; however, mobile display also has adverse impacts on our vision and may even injure our eyes. Mobile devices cause visual discomfort mainly due to handheld shake and vibration, especially when they are used in moving environments. In this paper, we propose an anti-shake mechanism for mobile display. This mechanism is aimed to provide users with a comfortable interaction experience and minimize negative side effects of screen vibrations. The overall process of the anti-shake mechanism includes analyzing the accelerometer data, predicting the magnitude of device displacement, and adjusting the position of the display area to compensate for vibrations. A system modeling based technique was developed as the kernel for motion prediction and display stabilization. We then verified this technique with prediction accuracy test and user evaluation test. The experimental results reveal that our anti-shake mechanism can precisely simulate ground-truth displacement and successfully decrease sight fatigue when applied to mobile devices used in dynamically changing environments.
