soft-VNS system, runs within MAX/MSP on macOS -> http://www.interlog.com/~drokeby/softVNS.html 

Intel's computer vision library is aimed mainly at real time computer vision. Some example areas would be Human-Computer Interaction (HCI); Object Identification, Segmentation and Recognition; Face Recognition; Gesture Recognition; Motion Tracking, Ego Motion, Motion Understanding; Structure From Motion (SFM); and Mobile Robotics.

Xvision "provides an application independent set of tools for visual feature tracking optimized to be simple to configure at the user level, yet extremely fast to execute." developed for comodity hardware and available software, requires xwindows -> http://www.cs.jhu.edu/CIRL/html/xvision.html

==== Floor + pressure sensing ====


Touch sensitive dance floor -- interesting hardware solution, made for MIDI dance performances -> http://www.utexas.edu/cofa/music/ems/research/midifloor/midifloor.html They use Force Sensing Resistors (FSRs) from Interlink Corporation -> http://www.interlinkelectronics.com/
