Thermal-radiation-based haptic display—calibration and shape display

Abstract

When a human places his hands over a source of heat, his hands become warm owing to thermal radiation. In this research, we employ spatially controlled thermal radiation to display a virtual shape. At a temperature near the nociceptive temperature, a person will tend to avoid a heated region. Using this space, our proposed system displays the virtual shape-like region. In this paper, we describe the proposed radiation system and calibration method.
