Computer interface employing a wearable article with an absolute pose detection component
DC CAFCFirst Claim
1. A wearable article cooperating with a first plurality of predetermined light sources disposed in a known pattern, said wearable article comprising:
- a) a photodetector configured to detect said first plurality of predetermined light sources and generate photodetector data representative of the positions of said first plurality of predetermined light sources; and
b) a controller configured to identify a derivative pattern of said first plurality of predetermined light sources from said photodetector data, wherein said derivative pattern is indicative of the position of said photodetector.

Abstract
A wearable article, such as glasses for a virtual reality program or glasses for an augmented reality application, using light sources and a photodetector that detects their light and outputs data indicative of the detected light. The wearable article uses one or more controllers to determine its position and/or orientation in the environment based on the data output by the photodetector. Data from one or more auxiliary motion sensing devices, e.g., a relative motion sensor such as an inertial device or other auxiliary motion device relying on acoustics, optics or electromagnetic waves within or outside the visible spectrum, can be used to supplement the position and/or orientation data from the photodetector.
