intendiX is a commercial brain-computer interface (BCI) environment. intendiX was introduced in 2009 by Guger Technologies OG, or g.tec, an Austrian company that manufactures BCI systems and components. intendiX is designed as a personal BCI that anyone can use without technical training or outside support. It is robust to many types of environmental noise and can operate in home or hospital environments. Most people can use intendiX to spell five to ten characters per minute within about ten minutes of training. While intendiX has been used as an assistive technology by persons with severe disabilities, performance may be worse among users with disabilities due to fatigue, visual deficits, or impaired concentration, attention, or memory.
