When presenting tactile sensations to 3D models, directly using high-resolution shape information increases the communication and computational load, and using pseudo-random numbers alone results in a monotonous sensation. Therefore, the challenge is to achieve natural and diverse tactile sensations with low load. [Solution] This invention is a method for achieving tactile feedback that combines smoothness and natural variation by generating a structured and smooth basic unevenness pattern using a pseudorandom number generator and adding a non-deterministic fluctuation component using a quantum random number generator. The contributions of both are controlled by a weighting function that varies over time depending on the user's operation speed, direction, contact duration, etc., and the tactile unevenness height corresponding to the coordinates on the 3D model is calculated to drive the tactile reproduction device. The tactile reproduction device can be either a device that outputs physical stimuli or an interface device that provides stimulating signals to the nerves and brain, enabling realistic and diverse tactile presentation with low load.
