Researchers at Carnegie Mellon
University and Disney Research Pittsburgh have devised a motion tracking
technology that could eliminate much of the annoying lag that occurs in
existing video game systems that use motion tracking, while also being extremely
precise and highly affordable. Called Lumitrack, the technology has two
components -- projectors and sensors. A structured pattern, which looks
something like a very large barcode, is projected over the area to be tracked.
Sensor units, either near the
projector or on the person or object being tracked, can then quickly and
precisely locate movements anywhere in that area. Lumitrack also is extremely
precise, with sub-millimeter accuracy. Moreover, this performance is achieved
at low cost. The sensors require little power and would be inexpensive to
assemble in volume. The components could even be integrated into mobile
devices, such as smartphones.
