Comparison of wide-band vibrotactile and friction modulation surface gratings

Autor: Grigorii, Roman V., Li, Yifei, Peshkin, Michael A., Colgate, J. Edward

This study seeks to understand conditions under which virtual gratings produced via vibrotaction and friction modulation are perceived as similar and to find physical origins in the results. To accomplish this, we developed two single-axis devices, o

Building a navigable fine texture design space

Autor: Friesen, Rebecca Fenton, Klatzky, Roberta L., Peshkin, Michael A., Colgate, J. Edward

Friction modulation technology enables the creation of textural effects on flat haptic displays. However, an intuitive and manageably small design space for construction of such haptic textures remains an unfulfilled goal for user interface designers

Closed loop application of electroadhesion for increased precision in texture rendering

Autor: Grigorii, Roman V., Colgate, J. Edward

Tactile displays based on friction modulation offer wide-bandwidth forces rendered directly on the fingertip. However, due to a number of touch conditions (e.g., normal force, skin hydration) that result in variations in the friction force and the st

Localizable Button Click Rendering via Active Lateral Force Feedback

Autor: Xu, Heng, Klatzky, Roberta L., Peshkin, Michael A., Colgate, J. Edward

We have developed a novel button click rendering mechanism based on active lateral force feedback. The effect can be localized because electroadhesion between a finger and a surface can be localized. Psychophysical experiments were conducted to evalu

How the Mechanical Properties and Thickness of Glass Affect TPaD Performance

Autor: Xu, Heng, Peshkin, Michael A., Colgate, J. Edward

One well-known class of surface haptic devices that we have called TPaDs (Tactile Pattern Displays) uses ultrasonic transverse vibrations of a touch surface to modulate fingertip friction. This paper addresses the power consumption of glass TPaDs, wh
