Brain activity as an important measure for human machine interface design

Physiological data such as pulse, respiration, muscle activity and skin conductance already give a good impression of the operators condition. If mental activity should be measured on top of these values a dedicated sensor is necessary. This measurement can be achieved by using a near-infrared spectroscopy (NIRS) sensor which is attached to the head with a simple strap.
Now mental activity can be measured synchronously together with the data of other sensors. As machines get more and more sophisticated user interfaces and features, it is important not to overload the operator and make sure the mental workload stays in the right level. As an example we can see the trend with assistive systems in cars. They already support the driver in complex situations but also need a higher concentration to operate them.

How does it work?

D-LAB enables the synchronous recording and analysis of data from various sensors, such as eye tracking systems, video cameras, microphones, physiological devices and any network data via TCP/IP or CAN bus of a vehicle. These different data channels can be recorded and processed independently of frequency.

The D-LAB Connect module also supports the physiological sensors of Thought Technology. These include the HEG sensor, which measures the brain activity and can be quickly and easily connected to D-LAB using a planned Plug & Play solution.
