We are in search of new technologies for actuating Braille dots that can be packed tightly enough to support a full page Braille display. Current Braille displays rely on bulky mechanical actuators that cannot support multiple lines of Braille. Imagine viewing your computer screen one line at a time. We propose to develop novel micro-fluidic actuators that can be combined with the dots they support into a single membrane. We aim to design a fluid-logic controller that will enable each dot in the display to be individually addressed and latched in its desired state. Finally, we aim to construct the display from an optically transparent material and index match the fluid it contains so that it can be overlaid on a touch screen. This will enable our technology to be applied far beyond the domain of Braille display to provide much-needed tactile feedback for mobile devices. In addition, we will explore the applicability of this technology for responsive surfaces in other domains such as drumpads for digital percussion instruments.
