Convergence of mobile devices with external high-quality UI devices

This paper presents a technique for an Android mobile device to best utilize its surrounding external display device such as high-definition TV, in order to overcome the size and resolution limitation of the small LCD in the mobile device. Unlike current techniques that simply expand the LCD screen image to an external large display, our technique dynamically changes the resolution adapting to capability of the external display. For this, we first identify technical hurdles in the Android platform for dynamic resolution adaptation. Then, we propose novel mechanisms to effectively address the technical hurdles. Those mechanisms are actually implemented on an Android mobile device, called “Odroid”. We also validate the usefulness of our mechanisms through user study.
