Electrovibrations, an infant technology for touch screens, are what my design is inspired and utilized by. The user feels a texture under his or her finger, which is caused by electrical charges sent to the pinpointed location on the screen that the finger is touching. This could be used to create the texture of a page of Braille, and my design implements this possibility to make touch screens for Braille communication. This would open up a massive variety of previously unavailable technologies, media, and communication for the blind. Some possibilities include email and text message as well as form completion and other disability services. The device could also be used like a Kindle or similar interactive reading device, making texts, books, and other media more available 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 the electrovibrations Braille could be digitally simulated underneath the moving finger touching the screen. With a particular algorithm, text could be digitally translated into Braille to be felt by the finger. The user interacts with this system (mapped below) by placing his or her finger on the screen and then moves it around to read what is on it. To depict a website format or button options, the texture could make the user feel a button around the text, indicated that that part of the screen acts like a button to be pressed. In order to activate the button the user must double-tap or use some other indication. The text would be mapped to the screen so the user can use both hands and multiple fingers, feeling the particular texture of whichever spot that the fingers are moving across. The dips and bumps can be felt even by a stationary finger. Since the user will constantly be touching the screen, the interactions required to do special actions such as turning a page or scrolling will be particularly designed based on the needs of Braille readers.
