Abstract

In this study, we propose and evaluate a warmth display, which is designed to heat a part of user’s hand when the part of the hand get warmth in virtual world displayed by Head Mounted Display. For the heat source, we use visible light LED because it is easily available and controllable. Arranging several LEDs around the hand, the display can warm some part of the hand. As it warms hands without contact, the heat from the display can be cut off immediately and interactive warmth presentation is possible. Moreover, we evaluated the safety, reaction time, sensation of warmth and temperature change caused by the display.
