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

我们已经为配备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，通过该稳定投影将投影内容固定在平面屏幕上而不受移动设备的运动的影响，并且在将投影内容固定在屏幕上时利用移动设备的运动进行了用户界面开发。研究结果包括一个投影机固件，用于在1300帧/秒的速度下对投影内容进行任意的单应性变换；一个利用系统与平面屏幕之间的几何约束的移动投影机-摄像机系统的姿态和位置估计算法；以及利用移动设备的姿态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.
