The Effect of Visually-Induced Pseudo-Haptic on Softness

Abstract

The visually-induced pseudo-haptic is a type of haptic illusion induced by a visual stimulus. This phenomenon is con-sidered to be helpful in formation of a haptic (force) display without using actuators. It is believed that this will con-tribute to the future popularization of such displays. However, most methods used to induce this phenomenon use a desktop size monitor and a mouse, which is a relatively large setup. In contrast, our previous work in the effects of pseudo-haptic on softness showed that a sensor-integrated smartphone is capable of inducing this phenomenon with-out using a mouse. In this paper, we will describe the smartphone-based system in detail, along with the results of ex-periments that we conducted to evaluate the effects of this phenomenon.
