Abstract: An electronic game system and a method of its operation are provided for virtual space mapping of a variable activity region in physical space. A calibration input may be received from a positioning device of a game controller that indicates waypoints that define an activity region in physical space. A scale factor may be identified between the activity region and an interactive game region in virtual space based on the calibration input. Positioning information may be received from the positioning device that indicates a position of the positioning device within the activity region. The position of the positioning device within the activity region may be mapped to a corresponding virtual position within the interactive game region based on the scale factor.

Abstract: Orientation in an external reference is determined. An external-frame acceleration for a device is determined, the external-frame acceleration being in an external reference frame relative to the device. An internal-frame acceleration for the device is determined, the internal-frame acceleration being in an internal reference frame relative to the device. An orientation of the device is determined based on a comparison between a direction of the external-frame acceleration and a direction of the internal-frame acceleration.

Abstract: Embodiments related to in-air cursor control solutions are disclosed. For example, one disclosed embodiment provides a method of moving a cursor on a display. The method comprises receiving an external motion signal from an image sensor that is external to a handheld cursor control device, receiving an internal motion signal from a motion detector internal to the handheld cursor control device, and sending an output signal to the display to change a location of the cursor on the display based upon the external motion signal and the internal motion signal.
