The object of this paper is to clarify the effect of temperature on the tactile response of building materials. The tactile (warmth, hardness, roughness, dryness, comfort) values of sixty materials were experimentally determined at the temperature of 10, 20 and 30℃. Within the room temperature of 10℃ to 30℃, psychological values of hardness, roughness and dryness are constant. Warmth values can be obtamned by the following equation. W_T=W_<20>+0.030(T-20) Where WT is tactile warmth value at T℃, W_<20> is tactile warmth value at 20℃, and T is the room temperature ℃. The tactile comfort values can be expressed by the following equation. Ar=(-0.10T+2.0)W_r+ (0.063 T-0.63)H_r+(-0.096T+0.96)R_T Where A_r is tactile comfort value at T℃, H_r is tactile warmth value at T℃, R_r is tactile hardness value at T℃, T is tactile roughness value at T℃ and T is the room temperature ℃. The tactile dryness values can be expressed by the following equation D_r=0.40R_<20>+0.60W_<20> Where D_r is tactile dryness value at T℃, R_<20> is tactile roughness value at 20℃, and W_<20> is tactile warmth value at 20℃.
