Three-dimensional hand guidance by midair haptic display
Guiding human movements using tactile information is one of the promising applications of haptics. Using midair ultrasonic haptic stimulation, it is possible to guide a hand without visual information.However, the information of movement shown by conventional methods was partial. It has not been shown a method to guide a hand to an arbitrary point in three dimensional space. In this study, we propose a method of guiding the hand to the top of a virtual cone presented haptically and evaluate the effectiveness of the method through experiments. As a result, the method guided the participant's hand to the goal in a 30 cm cube workspace with an error of 64.34 mm
