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.

The present disclosure relates to automatically monitoring a subject's slow wave response to sensory stimuli during a sleep session. Upon detecting deep NREM sleep, sensory stimuli can be delivered to the subject. The sensory stimuli can be auditory, tactile, visual, or other stimuli. The system delivers stimuli to the subject in the form of blocks of stimuli separated from each other by an intra-block interval. The blocks are separated from each other by an inter-block stimulus. The system compares the subject's stimulated slow wave activity to the subject's unstimulated slow wave activity. The system can update the stimulation parameters based on the comparison and deliver a subsequent block of stimuli. Once the comparison indicates that the stimulated slow wave activity is significantly different from the unstimulated slow wave activity, the system can apply a continuous fixed sensory stimulus to the user according to the most recent stimulation parameters.
