Abstract
In this paper, we proposed the e-Fovea, a multi-resolution projector-camera system. This system is designed in accordance with human visual perception system. Research on human visual perception system had conducted studies on the spatial variation in human visual resolution. Their studies had shown that only the fovea region of human eyes can afford sharp vision with acute visual details. In comparison, peripheral region of human eyes perceives rough percipience of the world with coarse visual details. Similarly, our system composed of a multi-resolution input channel and output display. The multi-resolution input channel consists of a wide-angle camera and a speed-dome camera. The multi-resolution output display consists of a fixed projector and a steerable projector. By the steerable projector, the high-resolution sub-view can move to various positions on the large display to “enhance” a certain local area. We want to create a cost-effective, attentive user interface that can help reduce human operator’s cognitive loads during their monitoring tasks. Two experiments are introduced to demonstrate the system. A user study is done to evaluate the performance of our system. We have shown in this thesis that the layout of the system and the technologies for the geometric calibrating input and output devices.
