概要 In this work we present a multi-touch wall display system that equips easily and considers occlusions problem using multiple range scanners. Our system is implemented on an existing large display embedded in a wall with two laser range scanners. Each scanner detects touches events including positions and/or areas. Some touch positions causes relative occlusions due to a range scanner. We reduce the problem by using multiple scanners. If the touch events from different scanners are the same, these are combined into one touch event. Detected multi-touch events are sent to the network as TUIO events. This system is simple and adaptable to various existing displays including front projection screens, and to various TUIO applications.
