Abstract:

At present, a vast number of technologies are designed specifically for users that are able to employ the use of sight. Additionally, many products designed to allow the visually impaired to use these technologies are expensive, and often not easy to use. In order to expand the benefits of technology to the visually impaired, we have invented an Electronic Braille Interface that can connect to any device with a USB port (laptops, cell phones, e-readers, etc.) and effectively translate ASCII characters from the device into physical Braille characters. The Braille text will be displayed on the Electronic Braille Interface though moveable pins that, in groups of six, are able to display different Braille characters in the same fashion as normal, stationary Braille text. The user will be able to feel the pins and interpret the Braille characters. The pins are raised through a magnetic write head, which moves from letter to letter through the use of a motorized positioning system in order to raise the correct pins for each character. The pins are held in their up or down states through a system of springs and magnets. This allows a very small set of motors to easily write all of the characters on the display. A pin is held in the up position through the attraction of a magnet on the bottom of the pin with an iron layer embedded into the screen. The spring is in equilibrium when the pin is in the down position, and is compressed when the pin is in the up position; so that it can effectively hold the pin in the down position by default. When the write head reaches the pin, it applies a current to a coil directly underneath the pin, which will produce enough magnetic force to make the pin switch to the up position. A bar magnet resets all of the pins simultaneously by moving across the entire device and creating a magnetic force that causes all of the pins to reset to the down position. Additionally, a software program will be installed on any device connecting to the Electronic Braille Interface in order to write, erase, and control the pins. Our Electronic Braille Interface will be low-cost, lightweight, and able to integrate well into existing devices. Future generations will include the capability of drawing images, creating interactive displays, and allowing the user to play games (similar to the games that people often play on their cell phones or tablets).
