Abstract: Measurement control part measures contact pressures and a contact speed of a hand of a contacting person. The contact pressures change over time at respective positions, as measured values respectively based on two sensors when the hand of the contacting person touches sequentially to the two sensors being capable of detecting contact pressure. A determination control part compares measured values with reference ranges respectively, the reference range being a predetermined for a contacted person feeling comfortable when touched by the contacting person, and determines whether or not the measured value is within the reference range for each of measured values. An evaluation control part evaluates that the touching of the contacting person is a comfortable touching when all the measured values are within corresponding reference ranges respectively, and evaluates that the touching of the contacting person is an uncomfortable touching when one measured value is outside the corresponding reference range.
