Quantification of Tactile Sensation Using a Pseudo-Weight Sensation Induced by Visual Stimuli

As a means of providing tactile sensation, it is possible to induce pseudo-haptic sensation by providing visual stimulation as well as tactile stimulation to the fingers. For example, when moving the cursor displayed on the display of a tablet device, if a time lag (response time) is created in the cursor movement, a pseudo-sensation of “heaviness” is induced, and it is predicted that a mechanical response will be shown, such as an increase in the force to move or push the cursor. By applying this phenomenon, it is possible to quantitatively express the tactile sensation of “heaviness” induced by visual stimuli using the visual stimuli that are input and the mechanical response that is output. In this study, the aim is to control visual stimuli such as display response time delays to give arbitrary tactile sensations, and to quantify the tactile sensations from the mechanical feedback.
