| As mobile technology continues to increase its role in the world's day-to-day activity, hand-held devices such as smart phones and tablets are becoming increasingly commonplace within corporate offices and meetings. These devices contain sufficient storage capacity and operating units to handle presentation material, yet their mobile design leaves little space to incorporate projection. Pico projectors hold a promising role in the future of mobile display, allowing imaging projection from handheld devices to be accomplished on a level small enough to be integrated on the ever-minimizing mobile platform.;The Graphics ICS department at UC Irvine has made great strides in working with pico projectors, including the iCVideo project, which uses these projectors to achieve an interactive collaborative video through a distributed system [9]. Using four separate sets of BeagleBoard-xM development boards, pico projectors, and imaging cameras, a synchronized video playback is achieved on a tiled display. A distributed registration algorithm is used for spatial calibration of the system, while the video frames are synchronized through a visual feedback-based video synchronization.;The goal of this research effort is to improve mobile usability of this system by applying the system onto two Nvidia Tegra tablets. To achieve this goal, a detailed model was established to replicate this system on an Android platform, using Nvidia's Android Software Development Kit to accomplish the necessary steps in creating this distributed display. Design variables included camera sensitivity, projection input, and image blending. Improvements in power and frequency usage via the Tegra system were also analyzed. |
