This paper presents the development of an augmented reality (AR) thermal display. This device is proposed to augment the thermal sense as the user's palm touches a real object. The concept used for AR thermal display is the phenomenon of spatial summation which related to skin's area of stimulation. The critical aspects of this display are the thermal display is placed on the back of hand and the palm can touch object directly. An experiment is conducted to identify whether spatial summation can occur between the back of hand and the palm. From this experiment, spatial summation is confirmed to take place when the same type of receptor is triggered on the back of hand and the palm. Moreover, the experiment proved that the AR thermal display is effective for augmentation of thermal sense; a cool and warm object was perceived colder and warmer respectively, than the actual temperature.
