Mobile User Interfaces using a High-Speed Projector-Camera System

我们已经为配备了视频投影仪的移动设备开发了用户界面。进行了用于稳定投影的系统开发，其中投影内容被固定在平面屏幕上而不受移动设备的运动的影响，并且在投影内容被固定在屏幕上的同时利用移动设备的运动的用户界面。其结果包括：将任意单应变换应用于1300帧/S的投影内容的投影仪固件；利用系统与平面屏幕之间的几何约束的移动投影仪-相机系统的姿势和位置估计算法；以及利用移动设备的姿势和动态运动的操作界面。

We have developed user interfaces for a mobile device equipped with a video projector. System development for stabilized projection by which the projected contents are fixed on a planar screen without being affected by the motion of the mobile device was carried out and user interfaces utilizing the motion of the mobile device while the projected contents are fixed on the screen. The results include namely a projector firmware to apply arbitrary homography transformations to the projected contents at 1300 frames/s, a pose and position estimation algorithm for a mobile projector-camera system exploiting geometric constraints between the system and the planar screen, and operation interfaces utilizing the pose and dynamic motion of a mobile device.
