WeWatch:An Application for Watching Video Across Two Mobile Devices

摘要

In recent years, high⁃resolution video has developed rapidly and widescreen smart devices have become popular. We present an Android application called WeWatch that enables high⁃resolution video to be shared across two mobile devices when they are close to each other. This concept has its inspiration in machine⁃to⁃machine connections in the Internet of Things (loT). We ensure that the two parts of the video are the same size over both screens and are synchronous. Further, a user can play, pause, or stop the video by moving one device a certain distance from the other. We decide on appropriate distances through experimentation. We implemented WeWatch on Android operating system and then optimize Watch so battery consumption is reduced. The user ex⁃perience provided by WeWatch was evaluated by students through a questionnaire, and the reviews indicated that WeWatch does improve the viewing experience.
