Haptic Master
The HapticMASTER from Moog is a haptic robot system with three degrees of freedom. While an end effector is being manipulated, forces can be generated with high temporal resolution to generate realistic haptic information. Due to the robust design and the high forces that can be generated, interactions can be simulated with objects of high stiffness. 
28-Camera Motion Capture System (Vicon)
Motion capture has a wide range of applications and can be used to analyze kinematic features of a variety of movements ranging from small-scaled pointing or grasping movements to larger scaled movements such as walking and running as well as specific sports-related skills such as throws in basketball or deceptive throws in handball.
Up to 28 Vicon motion capture cameras record the position of retroreflective markers attached to the body or the object to within 1 mm accuracy at up to 240 frames per second. This optical passive measurement method is considered to be the gold standard in the field of movement analysis. In our lab, the Vicon system is being used to assess and analyze movement patterns, to create stimuli for perception experiments (e.g., to examine the perception of emotional body movements), and to directly stream the reconstructed 3D coordinates to third-party devices in order, for example, to visualize movements in virtual reality scenarios.

Active marker motion tracking system (Steinbichler)
The Steinbichler 3D motion capturing system is an active marker system. This measuring method uses LED markers connected by wires to increase the contrast to the background. To facilitate marker identification, the LEDs are activated stroboscopically. We are using the Steinbichler system for applications with a restricted number of markers and a restricted range of movement. Because of the compact construction of the mobile tracking unit, it can also be used outside the lab. The system also provides real-time capabilities.
Eye tracking
The nemolab is equipped with eye trackers from different companies: SensoMotoric Instruments (Eye Tracking Glasses Device) and Pupil Labs GmbH. Eye movements can be recorded with a minimum frequency of 30 Hz and a maximum frequency of 200 Hz. All eye trackers are compatible with a recording unit that allows us to record gaze behavior not only in artificial laboratory situations but also under more natural and more complex conditions. 
TrakStar (Ascension Technology)
The TrakStar is an electromagnetic tracking device that can measure 3D positions. Our system consists of a control box, a reception box, and up to four sensors covering a range of approximately 1 × 1 × 1 meters at an interpolated 100 Hz sampling rate. With this device, we can carry out motor learning and control experiments in which participants control a screen cursor with their hand position.
