Motionbeam interaction techniques for handheld projectors

摘要

An image projection system may be configured to project objects which respond to movements and gestures made using a handheld projector, as well as to methods for controlling the projected objects based on such user input. For example, users may interact with and control objects in a projection frame by moving and/or gesturing with the handheld projector. Further, objects or characters projected using the handheld projector may be configured to perceive and react to physical objects in the environment. Similarly, elements of the physical environment may be configured to respond to the presence of the projected objects or characters in a variety of ways.

主权项

1. A computer-implemented method for presenting display frames projected using a handheld projector, the method comprising:
projecting a first display frame from the handheld projector, wherein the first display frame projects, on a display surface, one or more animated objects responsive to changes in position and orientation of the handheld projector; receiving an indication of a current position and orientation of the handheld projector; receiving a signal broadcast from a virtual environmental trigger affixed to the display surface, wherein the signal is received when the virtual environmental trigger is within a display frame projected by the handheld projector; and, generating one or more subsequent display frames projected from the handheld projector, wherein the animation of at least a first one of the animated objects in the one or more subsequent display frames depends on the current position and orientation of the handheld projector and further depends on the position of the virtual environmental trigger within the display frame.
