What is the "Pocket BCI" ?

Based on the mobile data acquisition system g.MOBIlab+ - the "Pocket BCI", i.e. a Brain-Computer Interface on the Pocket PC is now available.

A Brain-Computer Interface (BCI) converts brain signals into outputs that communicate a user's intent. Such a new communication channel does not rely on pheripheral nerves or muscles but on brain activity only.

Basic research in the field of Brain-Computer Interface started in the late 1980s / early 1990s. Nowadays BCI research teams can be found in all continents and the field of BCI research is still growing. Sophisticated BCI approaches have been introduced by several research teams (see also g.BCIsys).

However, BCI experiments are still mostly done in laboratory environment.

The "Pocket BCI" supports bridging the gap between laboratory experiment and practical applications. The portable g.MOBIlab+ can be easily installed in a subject's home or on a wheel chair. Standard BCI application like spelling devices can be integrated via an Application Programming Interface.

The "Pocket Brain-Computer Interface" is trained to the individual subjects brain waves and converts brain signals into control signals.

The BCI application shown here works in 2 steps:

Step 1) In the training phase the device is trained to the subjects brain patterns. Two distinct brain patterns are needed to operate e.g. a simple an on/off switch.

Step 2) In the application phase the subject operates the BCI and extends deliberately a cursor on the screen to the left and right direction.

Extensions:

The system supports to control also digital I/Os lines and additional analog IN lines via the Application Programming Interface. Hence user specific adaptations can be made easily to control also external devices by the "Pocket BCI".
