BRAILLE II implements a cheap, simple and portable multi-line Braille display compatible with any touch screen device, allowing low-income blind users to get access to education, public services and work opportunities easier than ever.
The device implements a mechanism that can generate Braille symbols and automatically slide them across user's finger, imitating the tactile feedback they would get reading ordinary Braille text. User's other hand is used to navigate across the surface of the screen of, let's say, a tablet. Said tablet reads touch coordinates and transmits a corresponding letter to BRAILLE II which is subsequently displayed to the user. Any graphical or console interface can be made available in Braille just by sending corresponding symbol commands to BRAILLE II on touch, the interface itself doesn't need to be changed.
No other device on the market separates navigation on the screen and actual physical Braille symbols presented to the user. Existing multi-line solutions essentially extend existing single-line concepts, thus being bound by their fundamental limits.
BRAILLE II chooses to take a step back and look at delivering a feeling of reading Braille by implementing only two elements:
- A single symbol generator with high refresh rate
- A mechanism that slides the symbol across user's finger imitating ordinary Braille reading
Provided solution not only makes BRAILLE II displays extremely cheap and simple in manufacturing, but also much more flexible as BRAILLE II doesn't need its own screen and can connect to any touchscreen device, be it a personal one or some public screen like an electronic transport timetable, metro map, an information stand or a museum guide. This makes it perfect for usage in education, work or personal activities.
Compared to existing single-line Braille displays that can cost several thousands of euros/dollars due to lots of precise piezoelectric mechanical elements used, BRAILLE II, due to its simplicity, is estimated to cost a couple hundreds at most, depending on the scale of manufacturing.
