InteractiveDESK: a computer-augmented desk which responds to operations on real objects

Office and engineering workers’ workloads are reduced with a computer-augmented desk named InteractiveDESK. The desk has a large desktop display with a pen-input facility and an ordinary upright display with a keyboard, thus integrating features of conventional systems and pen-based systems. The desk detects the operations on real objects on its real desk top, and responds to the operations to reduce users’ workloads. The prototype of the desk assists users in switching input methods and retrieving electronic files.

Development of image processing LSI SuperVchip for real-time vision systems

A new image processing LSI SuperVchip with high-performance computing power has been developed. The SuperVchip has powerful capability for vision systems as follows: 1. General image processing by 3x3, 5x5, 7x7 kernel for high speed filtering function. 2. 16-parallel gray search engine units for robust template matching. 3. 49 block matching Pes to calculate the summation of the absolution difference in parallel for stereo vision function. 4. A color extraction unit for color object recognition. The SuperVchip also has peripheral function of vision systems, such as video interface, PCI extended interface, RISC engine interface and image memory controller on a chip. Therefore, small and high performance vision systems are realized via SuperVchip. In this paper, the above specific circuits are presented, and an architecture of a vision device equipped with SuperVchip and its performance are also described.
