HamsaTouch: feel the world through your palm
Pages 571 - 574
Abstract
We developed a novel tactile vision substitution system (TVSS) for the people with visual impairments. The system is composed of an electro-tactile display with 512 electrodes, the same number of optical sensors beneath each electrode, and a smartphone with a camera and an LCD. The smartphone acquires the surrounding view, conducts image processing and displays the image on the LCD. The image is captured by the optical sensors and converted to a tactile image by the electro-tactile display. While the concept of the TVSS is classic, combining the commonly available mobile device and electro-tactile display enables a low cost yet powerful and compact system. Furthermore, optical communication architecture enables an open development environment, and it can be independently used as a paper-reading tool without the smartphone.

Tactile Presentation to the Back of a Smartphone with Simultaneous Screen Operation
CHI '16: Proceedings of the 2016 CHI Conference on Human Factors in Computing SystemsThe most common method of presenting tactile stimuli to touch screens has been to directly attach a tactile display to the screens. This requires a transparent tactile display so that the view is not obstructed. In contrast, transparency is not required ...
