In order to reduce the discomfort caused by body chillness, we have developed a wearable individual heating device to be mounted on the wrist. This device provides a hot thermal sensation in the arm and the whole body by warming only the back of the wrist. However, it does not provide enough thermal sensation to affect fingertips chillness. We verified whether the thermal sensation of the body, including the extremities, is improved by changing the position where the wrist is warmed. Experiments were conducted under environment conditions of 20°C temperature, and 50% humidity, and we evaluated the thermal and comfort feeling of both fingertips and body at the time of warming the wrist at three different positions. |
