FRC technology mainly uses the visual inertia of human eyes which can be regarded as persistence of vision phenomenon by sequential frames. It is especially important to make the 6 bit panel display abundant colors. The paper has deeply researched some possible stripes of the FRC algorithm caused by fixed pattern. A novel stripe removable algorithm has been brought up. It can effectively avoid the horizontal, vertical or diagonal stripe by displaying different temporal and spatial patterns. Various experiments show that the novel algorithm can display high resolution image in the lowly variety devices. © (2013) Trans Tech Publications, Switzerland.

Large touch screen systems (LTSS) have been widely used in scientific, industrial, educational and artistic domains. They are easy and natural for people to use. We present a novel touch screen interaction with finger pointing and operating. To track the high freedom of fingertips with quick changes and self-occlusion by using ordinary cameras is a complex and challenging task. We propose a series of computer vision (CV) algorithms to fix initial position, coordinates mapping, fingertip detection, fingertip tracking, fingertip pose recognition, and generate control instructions. Evaluation shows our system is simply implemented and has a great effect. © (2013) Trans Tech Publications, Switzerland.
