EEG Keyboard

Johns Hopkins University, 2004 - $14,400

This E-Team developed the EEG Keyboard, a Brain-Computer Interface (BCI) typewriter system capable of translating electroencephalogram signals generated from electrical activity in the brain into characters on a screen. Electrodes are attached to the user's scalp, and he or she chooses characters either by focusing on a certain row or column in a flashing six-by-six matrix or by staring at a region of the screen flashing at a certain known frequency. Initially the product was targeted at the Locked-In Syndrome (LIS) community--individuals with paralysis of all voluntary muscles in the body, leaving them virtually unable to communicate.

The E-Team consisted of two professors of biomedical engineering (one of which won the 2003 BCI competition), eight biomedical engineering undergraduates, and three faculty advisors: one from neurology, one from biomedical engineering, and one from business.
