In order to establish high-speed robot senses that are much faster than human senses, we are conducting research and development of information systems and devices that can achieve real-time image processing at 1000 frames/s or greater. As well as integrated algorithms to accelerate sensor information processing, we are also studying new sensing methodologies based on vibration and flow dynamics; they are too fast for humans to sense.

Real-time Finger Tapping Interface

In this study, we propose a finger-tapping interface called FINGERTAP, which can estimate the contact states and forces on human fingertips in real time using only the fingertip positions measured by high-speed vision cameras. In particular, we focus on the high-frequency component that develops at the moment when a fingertip contacts something. We introduce a real-time estimation algorithm for the fingertip contact state and force using frequency filtering to detect the high-frequency movement component of the fingertip positions.

We also introduce a clickable pointing interface and a virtual musical instrument as demonstration application examples using the FINGERTAP system, and we show the effectiveness of nonmountable type finger-tapping interfaces, which can estimate the fingertip positions and their contact forces simultaneously.
