VZ4000v
For motion capture users who require more accuracy and exclusive
features, Phoenix Technologies is proud to offer the new
Visualeyez VZ4000v trackers. VZ4000v still
provides all the sensing features of its predecessor (VZ4000),
except now it can also activate vibrator-equipped markers (individually) to provide distributed
tactile stimuli or cues to the subject(s) in real-time, thus enabling new R&D possibilities
especially in the 'virtual' and neuroscientific fields.
A 'bvr' series VZ4000v tracker can now capture up to 4850 3D marker coordinates per second.
Multiple VZ4000v trackers setup practically arbitrarily can still be calibrated
Automatically and Adaptively by the VZAutoCal, and now even instantly by the latest
VZInstaCal in case the tracker mounting structure is flexible and/or in motion!
The VZ4000v system maintains backward compatibility with all software programs!
Each VZ4000v tracker features a thermal-cycled rigid carbon composite construction
for permanent calibration accuracy and stability, with a lightweight aluminum shell.
The elegantly designed aluminum tripod also doubles as a heavy duty protective case during
tracker transportation.
