N2 - In this paper, we aim to develop a new tactile feedback method for myoelectric prosthetic hands and model the relationship between delay time and sensation in vibration stimulation. For myoelectric prosthetic hands, the tactile sensation can be expressed by vibrating an oscillator attached to the socket based on information obtained from tactile sensors attached to the prosthesis's fingertips. In this case, if there is a time gap between the sensory input and the stimulus, there is a possibility of causing discomfort. Therefore, in the experiment performed, a delay time, Du [s], is set between the start of contact with an object and the start of vibration using a tactile sensor and conducted NRS evaluation. The results showed that the discomfort was generated up to Du = 0.4 [s] and then decreased according to the delay time. The results showed that the discomfort was induced by controlling the timing of the vibration stimulus.
