Motor Behavior Lab - Facility and Equipment

The Motor Behavior Laboratory is a 600 sq. ft. room located in the Department of Kinesiology at SFSU. Within this laboratory are seven workstations available for the purpose of quantitative and qualitative analyses of human movement.

Three different three-dimensional motion analysis systems are available for data collection. The first includes an eight-camera, 1.2 megapixel visible-red optical motion capture system (Vicon), which can automatically capture movement up to a frequency of 10,000Hz with sub 0.5 millimeter precision. The second includes a four-camera, infrared optical motion capture system (Qualisys), which can automatically capture movement at 60Hz. The third system includes two 60Hz video cameras for data collection, and utilizes custom movement analysis software (KA Video) for manual digitizing and data analysis.

Also available to the laboratory is a single Kistler 9286AA (piezoelectric) force plate and two AMTI force plates. Additionally, a head-mounted eye tracker, manufactured by Applied Science Laboratories (ASL 5000R) is available to the laboratory to accurately track the movement of the human eye. The Vicon optical motion capture system can be synchronized with the ASL 5000R and Kistler and AMTI force plates.

Commercially available software (BIOPAC Student Lab Pro 3.7) is available to collect and analyze the signal from a hand dynamometer (Biopac SS25L). The Biopac system is also equipped to collect Electromyograpy (SS2L/EL503 Electrode Lead Set) and Electrogoniometer (SS21L Twin Axis Goniometer) data. The laboratory is also equipped to measure grip force using Nano-17 pre-calibrated force-torque transducers (Assurance Technologies, Garner, NC) mounted on a plexi-glass object (4 cm x 5 cm x 9cm).
