The invention was produced by Free Art and Technology (FAT), OpenFrameworks, Graffiti Research Lab, and The Ebeling Group is offering "the second life" to disabled people. Researches developed a unique EyeWriter technology which allows persons to communicate with each other using only one eye. The device uses a camera which scans the apple of eye and reflects a line path which in the end produces an image.
Using a specifically designed software paralyzed human being is capable of drawing on the computer, by using virtual (imaginary) wrists. The person literally pictures him or herself drawing with a wrist. This will cause the eye to move as the person pretends draw, that is where the application is programmed to reflect the changes on the screen. The developers of this device aren't sure how important this tool may be to disabled people so the developers prices the EyeWriter at $50 dollars. The software application which is required to operate the tool and support is absolutely free.
