Intuitive user interface for mobile devices based on visual motion detection

摘要

The small form factor and unergonomic keys of mobile phones call for new and more natural approaches in user interface (UI) design. In this paper, we propose intuitive motion-based UI controls for mobile devices with built-in cameras based on the visual detection of the device's self-motion. We developed a car-racing game to test our new interface, and we conducted a user study to evaluate the accuracy, sensitivity, responsiveness and usability of our proposed system. Results show that our motion-based interface is well received by the users and clearly preferred over traditional button-based controls.
