Generation of cutaneous rabbit illusion using an array of solenoid actuators

Abstract

In this study, since we aimed to develop a device to evaluate dexterity by using illusions, we firstly developed and tested a device to generate cutaneous rabbit illusions. Then, we conducted a series of psychological experiments to investigate the relationship between the cutaneous rabbit illusion and the stimulus position, and one and the stimulus time difference. The results of the performance test showed that the system had sufficient time difference resolution. Furthermore, it was found that the distance between 75 mm and 125 mm, which was the distance between the second and third stimuli, was sufficient to produce the illusion, and that the longer the time difference between the second and third stimuli, the harder it was to produce the illusion.
