Interactive projection system for dual mobile projector devices

As the hardware technology grows rapidly, it leads to widespread use of mobile devices. The developers tend to build devices with higher performance and expand the unit with better functions to satisfy the increasing user demands. This paper discusses on how to achieve the interaction with projector between two mobile devices as well as its applications. When both devices' projection screens overlap, it is considered as one projection screen. Therefore, the object data on the screen are able to pass smoothly between both mobile devices in a real-time manner.
