Lumitrack is a motion capture technology developed by Robert Xiao, Chris Harrison and Scott Hudson at Carnegie Mellon University.
These types of sensors are used in video game controllers, such as Microsoft's Kinect, and in motion capture for movie and television production.
The projectors cover the tracked area with structured patterns called a binary m-sequence that resemble barcodes.
The series of bars encodes a series of an assortment of vertical lines of varying thicknesses, without repeating any combination of seven adjacent line types anywhere in the projected image.
[2] The sensors are simple to manufacture and require little power and features response times in the range of 2.5 milliseconds,[1] making them candidates for incorporation into other devices, such as phones.
