  • 1.Mae TidmanNovember 24, 2010 Electrovibrations, an infant technology for touch screens, are what my design isLCC 3710 Prin. Interaction DesignFinal Project design documentinspired and utilized by. The user feels a texture under his or her nger, which is causedby electrical charges sent to the pinpointed location on the screen that the nger istouching. This could be used to create the texture of a page of Braille, and my designimplements this possibility to make touch screens for Braille communication. This wouldopen up a massive variety of previously unavailable technologies, media, andcommunication for the blind. Some possibilities include email and text message as wellas form completion and other disability services. The device could also be used like aKindle or similar interactive reading device, making texts, books, and other media moreavailable to Braille readers. The technology could be used for communication for anyone who reads Braille.Those who are blind can not use current touch screen devices, but with theelectrovibrations Braille could be digitally simulated underneath the moving ngertouching the screen. With a particular algorithm, text could be digitally translated intoBraille to be felt by the nger. The user interacts with this system (mapped below) by placing his or her nger onthe screen and then moves it around to read what is on it. To depict a website format orbutton options, the texture could make the user feel a button around the text, indicatedthat that part of the screen acts like a button to be pressed. In order to activate thebutton the user must double-tap or use some other indication. The text would bemapped to the screen so the user can use both hands and multiple ngers, feeling theparticular texture of whichever spot that the ngers are moving across. The dips andbumps can be felt even by a stationary nger. Since the user will constantly be touchingthe screen, the interactions required to do special actions such as turning a page orscrolling will be particularly designed based on the needs of Braille readers.
