Abstract
A remote-controlled pointing system (32) includes a projector (36), an image sensor (34), and a controller (38). The projector (36) projects a beam (45) of light from a location in a projection plane (46) onto a scene (18). The image sensor (34) captures an image (54) of the scene (18) in a capture plane (50). The controller (38) performs operations that include transmitting the captured image (54) to a remote destination (14), receiving from the remote destination (14) a target beam location (44) in the capture plane (50), determining a location of the beam (45) in the capture plane (50), and changing the location in the projection plane (46) from which the beam (45) is projected based on the determined beam location and the target beam location (44).
Claims22
Apparatus (34), comprising:
- a projector (36) operable to project a beam (45) of light from a location in a projection plane (46) onto a scene (18);
- an image sensor (34) operable to capture an image (54) of the scene (18) in a capture plane (50);
- a controller (38) operable to perform operations comprising transmitting the captured image (54) to a remote destination (14), receiving from the remote destination (14) a target beam location (44) in the capture plane (50), determining a location of the beam (45) in the capture plane (50), and changing the location in the projection plane (46) from which the beam (45) is projected based on the determined beam location and the target beam location (44).
A machine-implemented method, comprising:
- projecting a beam (45) of light from a location in a projection plane (46) onto a scene (18);
- capturing an image (54) of the scene (18) in a capture plane (50);
- transmitting the captured image (54) to a remote destination (14);
- receiving from the remote destination (14) a target beam location (44) in the capture plane (50);
- determining a location of the beam (45) in the capture plane (50);
- and
- changing the location in the projection plane (46) from which the beam (45) is projected based on the determined beam location and the target beam location (44).
A computer-readable medium (157) storing computer-readable instructions causing a computer (154) to perform operations comprising:
- projecting a beam (45) of light from a location in a projection plane (46) onto a scene (18);
- capturing an image (54) of the scene (18) in a capture plane (50);
- transmitting the captured image (54) to a remote destination (14);
- receiving from the remote destination (14) a target beam location (44) in the capture plane (50);
- determining a location of the beam (45) in the capture plane (50);
- and
- changing the location in the projection plane (46) from which the beam (45) is projected based on the determined beam location and the target beam location (44).
