Abstract
A tracking system includes a stylus comprising a light emitter, a head-mounted device comprising an optical sensor configured to detect the light emitter, and a processor communicatively coupled to the optical sensor and configured to determine a position of the stylus based on detection of the light emitter.
Claims18
A tracking system comprising:
- a stylus comprising multiple light emitters, each of the light emitters having a size that is different than a size of every other one of the light emitters, wherein the light emitters comprise a first light emitter and a second light emitter, wherein the second light emitter is spaced apart from the first light emitter along a length of the stylus, wherein the first and second light emitters are configured to emit different wavelengths of light;
- and
- a head-mounted device comprising:
- an optical sensor configured to detect the light emitters;
- and
- a processor communicatively coupled to the optical sensor and configured to:
- determine a position of the stylus based on a detection of the light emitters;
- and
- disambiguate an orientation of the stylus based on a relative position of the different emitted wavelengths.
6 more elements
An electronic system comprising:
- a stylus having an elongate body, a tip at an end of the elongate body, and first light emitters longitudinally spaced apart from a second light emitter on the elongate body, the first light emitters being arranged to be separated from each other along a circumference of the elongate body, the second light emitter forming a ring that extends continuously about the circumference of the elongate body;
- and
- a head-mounted device comprising a display configured to present graphics to a user wearing the head-mounted device, and an outward facing camera sensitive to the first light emitters and second light emitter, wherein the head-mounted device is configured to detect motion of the stylus in three-dimensional space based on detection of the first light emitters and second light emitter.
An electronic system comprising:
- a stylus having an elongate body, a tip at an end of the elongate body, and multiple light emitters spaced apart about a circumference of the stylus, the light emitters having wavelengths that vary along the circumference;
- and
- a head-mounted device comprising a display configured to present graphics to a user wearing the head-mounted device, and an outward facing camera sensitive to the light emitters, wherein the head-mounted device is configured to detect an angular position in three-dimensional space based on detection of the wavelengths of the light emitters.
