What People Want to Touch in Daily Life

In this study, we tried to gain insights into targets people want to touch in their daily lives by conducting a Twitter survey wherein …

Impact Vibration Localization

This study investigated the localization ability of an impulse vibration source outside the body in two-dimensional space. We tested …

Inside Touch

This study attempts to provide a tactile feeling on the space inside a virtual object when fingers penetrate it. We attempt to present …

Survey of Pseudo Haptics

In this paper, findings from a series of individual prior studies were summarized from the design through to the application proposals. …

High Density Pin Arrays

This study proposes a novel design of a finger-mounted pin-array display that works around the constraint. We adopted a pneumatic drive …

Pseudo-haptic Roughness on Finger

Previously, we proposed a pseudo-haptic method of changing the perceived roughness of virtual textured surfaces represented by …

Vibrator Transparency

We define the ‘‘vibrator transparent system’’ as a control system that absorbs the difference in vibrator …

Pseudo-haptic Friction

In this study, we propose a new method for presenting static frictional sensation using the pseudo-haptic effect as a first attempt, …

GAN-based Vibrotactile Design

We propose a new generative model that realizes the vibrotactile generation automatically based on texture images or material …

Simulating Wearable Pin-array Display

We prepared a real testing environment where the user touched the real object, and where we could simulate both the sparse contact …

Pseudo-haptic Roughness

We focus on fine roughness perception and we propose a method using a pseudo-haptic effect to modulate fine roughness perception of …

Pseudo-haptics on Touchscreen

We proposes a method that renders haptic perceptions only using a touchscreen based on visuo-haptic interaction. The method evokes a …
