Abstract

Methods and devices for calculating the position of a movable device are disclosed. The device may include multiple optical detectors (ODs) and the movable device may include light sources. Optics may be above the ODs. A controller may calculate the position of the light source based on data from the ODs and properties of the optics. The device may be a game console, and the light source may be a game controller. The roles of the OD and light sources may be interchanged. The rotation of the movable device may be determined using multiple light sources and/or multiple ODs on the movable device. The movable device may calculate its position and transmit it to a console. The light sources may be modulated by time or frequency to distinguish between the light sources. There may be two or more movable devices. There may be two or more consoles.

Claims

1-32. -32. (canceled)

33. A device for calculating the rotation of a movable device, comprising:

an optical detector;

a controller communicatively coupled to the optical detector, configured to calculate rotational information of a movable device based on data generated by the optical detector from receiving light from at least two light sources of the movable device.

34. The device of claim 33, wherein the controller is further configured to calculate the rotational information based on the spatial distribution pattern of the light received at the optical detector.

35. The device of claim 33, wherein the at least two light sources are used to calculate the rotation of the movable device about one axis and wherein the controller is further configured to:

calculate rotational information about a second axis based on data generated by the optical detector from receiving light from at least two additional light sources of the movable device.
