EEG Shielding Cabin

Contact person: Dr. rer. nat. Elsa Andrea Kirchner

The EEG Shielding Cabin offers the possibility of carrying out EEG/EMG tests without the influence of electromagnetic interference. Inside the shielding cabin, external influences such as light, temperature, and ambient noise, which act on the subject, are very well controlled.  The shielding cabin is used for EEG/EMG measurements within the projects IMMI and RECUPERA-Reha, as well as for motion capture, supported by further sensors like a Qualysis motion tracking system within the project BesMan.

EEG measuring instruments

The EEG/EMG measuring devices are manufactured by the Brain Products GmbH. 4 DC-capable EEG amplifiers (one also fMRI-capable) are used in the shielding cabin. In addition, a so-called electrode cap system (actiCAP) in versions with 32, 64, and 128 electrodes is used. Furthermore, there is a 32-electrode cap system, fMRI-capable, in sizes 56, 58, and 60 cm. 

Further EEG/EMG measuring devices:
Bipolar amplifier:
Type: ExG MR (fMRI-capable)
Version: 8 bipolar channels (16 channels)
Emotive Dry Cap System:
Version: 14 channels, wireless
EEG hardware (ANT Neuro, Netherlands)1 mobile 128-channel eego™ mylab-system, additionally 3 different 64-channel caps (sizes: S, M, and L) and a 64-channel dry electrode cap
EEG hardware (Emotive Inc., USA)1 x 14-channel emotive dry cap system, wireless


The EEG shielding cabin is a cube of size 3 by 3 by 3 meters, equipped with 3 cameras, one beamer, one tracking system, and a special lighting system composed of 12 LED spots and one monitor.

Resolution: 659 x 493 Resolution: 720 x 576
Operating voltage: 12 V Operating voltage: 12 V
Max. frame rate: 202 fps Max. frame rate: 25 fps

The M3 MPro 150 beamer has a resolution of 640 x 480 and an operating voltage of 5 V.
The ultrasonic motion tracking system IS-900 (InterSense, USA) is designed to track the subject’s head as well as the hand. The system has 6 degrees of freedom: X, Y, Z, yaw, pitch and roll. It works with a resolution of 0.75 mm / 0.05°, a frequency of 180 Hz and the latency is about 4 ms.

The MiniCAVE contains a multi-display environment consisting of three clients, one master and one server, and serves as a test and development environment for the Virtual Reality Lab. Longer EEG experiments and studies on interaction with multi-display environments are performed here, e.g. within the projects IMMI and TransTerrA.
Additionally, the MiniCAVE includes a marker-based motion capturing system that nearly covers the entire space by means of 9 cameras. Movement data can be recorded, as e.g. within the project BesMan, and be used for machine learning or interaction.


In the MiniCAVE, the Intersense tracking system IS-900 is used, providing control via a so-called wand in addition to head and hand tracker.


  • 6 degrees of freedom: X, Y, Z, Yaw, Pitch and Roll
  • Resolution: 0.75 mm / 0.05°
  • Sampling frequency: 180 Hz
  • Latency: 4 ms

We also use the marker-based motion capturing system made by Qualisys, which captures the movements inside the room with maximum nine wall-mounted cameras.

IMMI: Adaptation of a man-machine interface for multi-robot control with respect to task engagement using embedded Brain Reading

The video shows a man-machine interface for multi robot control that is adapted online with respect to task load and task engagement to improve user support and efficiency of interaction by means of embedded Brain 
 Reading (eBR). The level of task engagement is inferred from the single-trial detectability of 
P300-related brain activity with 
the need for a secondary task to measure task load.

Analysis Room

Contact person: Marc Tabie, M.Sc.

The analysis room is equipped with many powerful computers for evaluation of large amounts of data being generated by measuring EEG and EMG signals. Quite often these signals are made up of data from 136 channels, which can be recorded at 5000 Hz. In addition, the analysis room accommodates temporary structures and experiments with smaller robotic systems or parts of systems.

RECUPERA-Reha Integration Room

Contact person: Dipl. Ing. Martin Mallwitz

The RECUPERA-Reha integration room used for the integration of exoskeletons provides tools that are necessary for the mechanical integration. In addition, there are two electrical power supply devices and an oscilloscope to calibrate and validate drives. Moreover, four PC workstations are available for development of the systems‘ control software and for data analysis. Shelves provide storage space for mechanical components and documentation.
