Abstract
In this paper, we proposed a multi-resolution display system that 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 multi-resolution display system projects a large low-resolution area and a high-resolution sub-view by a fixed projector system and a steerable projector system. 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 have shown in this paper that the technologies for calibrating and interacting with this system. We design an user interface for a user to interact with the multi-resolution display by using a laser pointer to direct the projection of the steerable projector. Three experiments are introduced to demonstrate the system. A user study is done to evaluate the performance of our system. The system has great potential to be combined with various techniques to develop practical or interesting applications.
