Abstract
A head-worn computer includes a camera system positioned to capture a surrounding environment in front of a user, a processor that identifies a position of a plurality of light emitters mounted on a hand-held controller from images captured by the camera system and tracks the position of the plurality of light emitters as the hand-held controller moves in the surrounding environment and interprets the tracked position as positional changes of the hand-held controller. The processor uses the position of the plurality of light emitters as markers in three dimensional space, the markers used as an anchor for virtual content presented in a see-through display of the head-worn computer.
Claims6
A head-worn computer, comprising:
- a camera system positioned to capture a surrounding environment in front of a user wearing the head-worn computer;
- a processor adapted to identify a position of a plurality of light emitters mounted on a hand-held controller from images captured by the camera system;
- the processor further adapted to track the position of the plurality of light emitters as the hand-held controller moves in the surrounding environment and interpret the tracked position as positional changes of the hand-held controller;
- and
- the processor further adapted to use the position of the plurality of light emitters as markers in three dimensional space, the markers used as an anchor for virtual content presented in a see-through display of the head-worn computer.
A head-worn computer, comprising:
- a camera system positioned to capture a surrounding environment in front of a user wearing the head-worn computer;
- a processor adapted to identify a position of a plurality of light emitters mounted on a hand-held controller in images captured by the camera system;
- the processor further adapted to track the position of the plurality of light emitters as the hand-held controller moves in the surrounding environment and interpret the track as positional changes of the hand-held controller;
- and
- the processor further adapted to use the position of the plurality of light emitters as a prediction of the position of the hand-held controller in three dimensional space, the predicted position used as a control input for a software application operating on the head-worn computer.
