Tactile Graphics

This project investigates the rendering of tactile graphics by lateral skin deformation. Graphics are rendered using three methods that produce localized vibrations, raised dot patterns, and gratings of arbitrary spatial frequency and orientation.

Braille

This project investigates the feasibility of rendering Braille using laterotactile stimulation. The project began with the rendering of lines of Braille dots on the VBD, a 1D tactile display designed for this purpose. The work was later extended to the display of complete Braille characters witht the STReSS2, a general-purpose 2D tactile display.

Mobile Haptics

This project is a tight collaboration with the University of British Columbia's SPIN lab under Prof. Karon MacLean's supervision.

Tracking of skin deformation

Developing rendering algorithms for laterotactile displays is challenging. This project explored a novel approach to the problem that consists in imaging fingerprint deformations during tactile exploration and applying image processing algorithms to track features and changes in local skin strain.
