Abstract
A system is provided, including: a peripheral device having a plurality of electromagnets; a glove interface object, the glove interface object having one or more magnetic sensors configured to sense magnetic fields generated by the electromagnets to determine a location of the glove interface object in an interactive environment, the glove interface object further having one or more inertial sensors configured to detect an orientation of the glove interface object.
Claims18
A system, comprising:
- a peripheral device having a plurality of electromagnets;
- a glove interface object, the glove interface object having one or more magnetic sensors configured to sense magnetic fields generated by the electromagnets to determine a location of the glove interface object in an interactive environment, the glove interface object further having one or more inertial sensors configured to detect an orientation of the glove interface object, the glove interface object further having a transmitter configured to transmit data derived from the magnetic sensors and the inertial sensors to a computing device for processing to generate data representing a pose of a virtual hand, the virtual hand capable of being rendered in a virtual environment presented on a head-mounted display;
- wherein the plurality of electromagnets include a first set of electromagnets that are activated when the glove interface object moves within a predefined distance of the peripheral device, and a second set of electromagnets that are activated when the glove interface object moves beyond the predefined distance;
- and,
- wherein the magnetic sensors sense the magnetic fields generated by the first set of electromagnets when the glove interface object moves within the predefined distance of the peripheral device, and wherein the magnetic sensors sense the magnetic fields generated by the second set of electromagnets when the glove interface object moves beyond the predefined distance.

A system, comprising:
- a device having a plurality of emitters;
- a glove interface object, the glove interface object having one or more sensors configured to sense signals generated by the emitters to determine a location of the glove interface object in an interactive environment, the glove interface object further having one or more inertial sensors configured to detect an orientation of the glove interface object, the glove interface object further having a transmitter configured to transmit data derived from the magnetic sensors and the inertial sensors to a computing device for processing to generate data representing a pose of a virtual hand, the virtual hand capable of being rendered in a virtual environment presented on a head-mounted display;
- wherein the plurality of emitters include a first set of emitters that are activated when the glove interface object moves within a predefined distance of the device, and a second set of emitters that are activated when the glove interface object moves beyond the predefined distance;
- and,
- wherein the sensors sense the signals generated by the first set of emitters when the glove interface object moves within the predefined distance of the device, and wherein the sensors sense the signals generated by the second set of emitters when the glove interface object moves beyond the predefined distance.
2 more elements
A method, comprising:
- activating a glove emitter positioned on a glove interface object;
- using a proximity sensor positioned at a fingertip portion of the glove interface object to determine a proximity of the fingertip portion to the glove emitter;
- in response to determining a location of the glove interface object within a predefined distance of a peripheral device, activating a peripheral emitter positioned at the peripheral device, and transitioning, from using the proximity sensor to determine the proximity of the fingertip portion to the glove emitter, to using the proximity sensor to determine a proximity of the fingertip portion to the peripheral emitter.
