intendiX speller

intendiX® speller is a brain computer interface designed to be installed and operated by caregivers or the patient’s family at home. The system uses visual evoked EEG potentials (VEP/P300) from the patient to enable the user to sequentially select characters from a keyboard-like matrix on the screen by paying attention to a desired letter for several seconds. It requires around 10 minutes of training and most subjects can use with reasonable performance, spelling 5 to 10 characters per minute at their first trial. Please note that for severely handicapped persons and patients close to the “locked-in state”, performance can vary widely and it depends on various factors such as training, visual ability, concentration, and cortical degeneration. We provide rentals of intendiX so that you can assess whether the system works for you.

A number of advances are built in to the speller. The intendiX® speller uses an intelligent algorithm to determine whether the user wants to use the system, so it doesn't spell accidentally. In addition to writing text, the patient can also use the system to trigger an alarm, let the computer speak the written text, print out or copy the text into an e-mail or to send commands to external devices. To control external devices a special extension tool called "extendiX" serves as an interface. extendiX runs on a separate computer that controls other devices and applications such as TVs, music, assistive robots, games and so on. extendiX just receives commands from intendiX®SPELLER via UDP and starts/executes the corresponding application or batch.

The EEG cap is comfortable, easy to clean, and with active electrodes that do not require any special skin preparation. Just put on the cap, inject a drop of gel into each of the electrodes and start to spell! intendiX®SPELLER includes the active electrode system, a portable EEG acquisition system and a notebook or netbook computer with the intendiX®SPELLER software installed. Also, ask for our new g.SAHARA dry electrodes.
