HACHIStack : 2層の光センサを用いた高速タッチパネルの開発(<特集>ハプティックコンテンツ)

抄録

This paper describes a novel photo touch sensing architecture, HACHIStack. It can measure the approaching velocity of an object and predict its contact time with the surface with low latency using two optical sensing layers above the surface. We conducted two laboratory experiments to confirm that the capabilities of HACHIStack are sufficient for haptic and auditory tapping interaction. We present three applications with HACHIStack: 1) chromatic percussions (xylophone and glockenspiel) with haptic feedback; 2) no-delay haptic feedback with the sensation of tapping on various simulated materials (e.g., rubber, wood and metal); and 3) a virtual piano instrument that allows players to perform weak and strong strokes by changing the tapping velocity.
