Mobile brain-computer interface on the Pocket PC

... bridging the gap between laboratory experiment and practical application.

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 peripheral nerves or muscles but on brain activity only.

Brain-computer interface

A Brain-Computer Interface (BCI) provides a new communication channel between the human brain and the computer. Mental activity leads to changes of electrophysiological signals like the electroencephalogram (EEG). The BCI system detects such changes and transforms it into a control signal which can, for example, be used to play a simple video game like in the picture above. One of the main goals is to enable completely paralyzed patients (locked-in syndrome) to communicate with their environment.

Biosignal Real-time Processing System under MATLAB/Simulink

g.RTsys is dedicated for biosignal and other technical signal data acquisition and real-time analysis. g.RTsys is available as PC version (16-, 32-, 48- or 64-analog input channels, digital inputs/ outputs, analog outputs) and as a portable, battery supplied notebook-version (PCMCIA board with 16- or 32 analog input channels). A connector box provides access to all inputs and out-puts to connect g.RTsys to g.BSamp and/or to g.STIMunit as well as to customer specific systems.

USB biosignal amplifier

...highly accurate biosignal data acquisition and processing system

g.USBamp - g.tec's latest 24 bit biosignal acquisition device - is the perfect tool for recording multimodal biosignal data with highest quality. This allows to investigate brain-, heart-, muscle-activity, eye movement, respiration, galvanic skin response and other body signals. g.USBamp is USB 2.0 enabled and comes with 16 simultaneous sampled biosignal channels and 2 analog output channels. A total of 4 independent grounds guarantee no interference between the recorded signals.  The amplifier is simply connected to the USB socket on your PC/Notebook and can immediately be used for data recording.  Record up to 256 channels using multiple g.USBamp devices.

Multi-modal data acquisition system with active electrodes

ActiveTwo is a powerful new high-resolution biosignal acquisition system that incorporates some revolutionary concepts.  Active electrode technology is just one of the significant innovations in the ActiveTwo system.  By placing active electronics within millimeters of the actual electrode contact, ActiveTwo virtually eliminates the need to prepare the scalp before applying electrodes.  This can cut measurement preparation time by an estimated 15 -30 minutes for most laboratories! 

ActiveTwo can also be equipped with additional sensors for respiration, skin conductance, temperature, plethysmograph (pulse) and other parameters.  An optional isolated analog input box makes it possible to acquire almost any type of signal synchronously with the signals sampled by the ActiveTwo A/D box.

As an added benefit, ActiveTwo comes with powerful data acquisition software developed in National Instruments' LabView.  We provide the compiled software so you do not need to own LabView, and you do not need to be a programmer to operate the system.  For those laboratories with programming resources, the source code is provided so that you can add any special features that you may need.
