Methods and apparatus for capturing motion from a self-tracking device are disclosed. In embodiments, a device self-tracks motion of the device relative to a first reference frame while recording motion of a subject relative to a second reference frame, the second reference frame being a reference frame relative to the device. In the embodiments, the subject may be a real object or, alternately, the subject may be a virtual subject and a motion of the virtual object may be recorded relative to the second reference frame by associating a position offset relative to the device with the position of the virtual object in the recorded motion. The motion of the subject relative to the first reference frame may be determined from the tracked motion of the device relative to the first frame and the recorded motion of the subject relative to the second reference frame.

A system and method for tap event location includes a device using a selection apparatus that provides accurate point locations. The device determines a 3-dimensional map of a scene in the view frustum of the device relative to a coordinate frame. The device receives an indication of the occurrence of a tap event comprising a contact of the selection apparatus with a subject, and determines the location of the tap event relative to the coordinate frame from the location of the selection apparatus. The location of the tap event may be used to determine a subject. Data associated with the subject may then be processed to provide effects in, or data about, the scene in the view frustum of the device. Embodiments include a selection apparatus that communicates occurrences of tap events to the device and includes features that allow the device to determine the location of the selection apparatus.

A control system is disclosed that is configurable (e.g., by a programmer) so as to enable input from multiple sources to capture to multiple controls. Also or alternatively, the system is configurable so as to enable input from multiple sources to capture to a single control. The system also provides a consistent and extendable scheme for filtering out conflicting events for individual controls. In one embodiment, this means that the system is configurable (e.g., based on the programmer's asserted preferences) so as to enable a selective determination as to whether additional inputs can be captured for a given control.
