US Patent:

20050005260, Jan 6, 2005

Filed:

Jul 2, 2003

Appl. No.:

10/611051

Inventors:

Michael Antonov - Highland MD, US

International Classification:

G06F007/00

US Classification:

717107000

Abstract:

A method of mapping abstract identifier implementations organized into namespaces may be used by parties (e.g., software developers) to combine identifier implementations with maximum flexibility, producing high-performance abstract code tailored to different application requirements and host binding environments. By expressing a bound entity via a parenthetical construct, multiple different implementations of the same abstract identifier can be uniquely identified and coexist together within the same program. A similar technique can also be used to uniquely identify extensions to existing types and namespaces developed by external parties without causing binding name clashes.

Abstract:

A virtual reality (VR) console receives slow calibration data from an imaging device and fast calibration data from an inertial measurement unit on a virtual reality headset. Using a model of the VR headset, the VR console identifies model locators corresponding to locators on the VR headset and generates estimated positions for locators included in slow calibration data. The VR console adjusts calibration parameters so a relative distance between estimated positions of the locators and positions of their corresponding model locators is less than a threshold value. From the estimated positions, the VR console generates calibrated positions of a reference point on the VR headset associated with images from the slow calibration data. The VR console determines predicted positions of the reference point from the calibrated positions and adjusts calibration parameters so intermediate estimated positions of the reference point are within a threshold distance of the predicted positions.
