Abstract

In some examples, information is sensed by an optical sensor responsive to light from a marker arranged to indicate a boundary of a physical user collaborative area to receive user-input marks during a video conference session, where the marker is distinct from the physical user collaborative area. Based on the received information, the boundary of the physical user collaborative area is determined. Based on the determined boundary, a video zoom into the physical user collaborative area during the video conference session is controlled.

First claim

What is claimed is:

1. A system comprising:
a processor; and
a non-transitory storage medium storing instructions executable on the processor to:
receive information sensed by an optical sensor responsive to light from a plurality of markers positioned at different locations of a boundary of a physical user collaborative area to receive user-input marks at a first participant location during a video conference session, wherein the plurality of markers are distinct from the physical user collaborative area;
based on the received information indicating the different locations of the boundary and further based on analyzing a smoothness of the physical user collaborative area in an image of the physical user collaborative area captured by a camera, determine the boundary of the physical user collaborative area;
control, based on the determined boundary, a video zoom into the physical user collaborative area during the video conference session;
save information of the determined boundary of the physical user collaborative area into a profile; and
for a subsequent video conference session involving participants at participant locations including the first participant location, access the profile to determine the boundary of the physical user collaborative area at the first participant location.

2. The system of claim 1 , wherein the received information comprises information sensed by a plurality of optical sensors responsive to the light from the plurality of markers.

3. The system of claim 1 , wherein the received information is responsive to the light from the plurality of markers positioned at different corners of the boundary of the physical user collaborative area.

4. The system of claim 3 , wherein the boundary of the physical user collaborative area is a rectangular boundary, and the determining of the boundary is based on the received information indicating corners of a rectangle.

5. The system of claim 1 , wherein a first light from a first marker of the plurality of markers is encoded with first information, and a second light from a second marker of the plurality of markers is encoded with second information different from the first information, and wherein the instructions are executable on the processor to:
distinguish between the plurality of markers based on the first and second information,
wherein the determining of the boundary is based on the distinguishing between the plurality of markers including the first marker positioned at a first location of the boundary, and the second marker positioned at a second location of the boundary.

6. The system of claim 5 , wherein the plurality of markers comprise a plurality of light emitters that transmit different digital codes, the different digital codes comprising the first and second information,
wherein the distinguishing between the plurality of markers is based on the different digital codes.

7. The system of claim 1 , wherein the plurality of markers comprise a plurality of light emitters, and the received information corresponds to light emitted from the plurality of light emitters as sensed by the optical sensor.

8. The system of claim 1 , wherein the plurality of markers comprise a plurality of light reflectors, and the received information corresponds to reflected light from the plurality of light reflectors as sensed by the optical sensor.

9. The system of claim 1 , wherein the instructions are executable on the processor to determine, based on the received information, the boundary of the physical user collaborative area without any user input to trigger the determining of the boundary of the physical user collaborative area.

10. A system comprising:
a processor; and
a non-transitory storage medium storing instructions executable on the processor to:
receive information sensed by an optical sensor responsive to light from a marker arranged to indicate a boundary of a physical user collaborative area to receive user-input marks at a first location during a video conference session, wherein the marker is distinct from the physical user collaborative area;
determine, based on the received information and further based on analyzing a smoothness of the physical user collaborative area in an image of the physical user collaborative area captured by a camera, the boundary of the physical user collaborative area;
control, based on the determined boundary, a video zoom into the physical user collaborative area during the video conference session;
save information of the determined boundary of the physical user collaborative area into a profile; and
for a subsequent video conference session involving participants at locations including the first location, access the profile to determine the boundary of the physical user collaborative area at the first location.

11. The system of claim 10 , wherein the received information sensed by the optical sensor is responsive to light from a plurality of markers placed at corners of the boundary of the physical user collaborative area, and wherein the determining of the boundary of the physical user collaborative area is based on identifying the corners of the boundary of the physical user collaborative area based on the received information.

12. The system of claim 11 , wherein the boundary of the physical user collaborative area is a rectangular boundary, and the determining of the boundary is based on the received information indicating corners of a rectangle.

13. A non-transitory machine-readable storage medium comprising instructions that upon execution cause a system to:
during a video conference session involving participants at a plurality of locations:
receive information sensed by an optical sensor at a first location of the plurality of locations, the received information responsive to light from a plurality of markers positioned at different points of a boundary of a physical user collaborative area to receive user-input marks at the first location, wherein the plurality of markers are distinct from the physical user collaborative area,
based on the received information indicating the different points of the boundary, determine the boundary of the physical user collaborative area,
control, in a video displayed by a video conference equipment at a second location of the plurality of locations, a video zoom into the physical user collaborative area, based on the determined boundary, and
save information relating to a location and the determined boundary of the physical user collaborative area into a profile; and

for a subsequent video conference session involving participants at locations including the first location, access the profile to determine the location of the physical user collaborative area and the boundary of the physical user collaborative area at the first location.

14. The non-transitory machine-readable storage medium of claim 13 , wherein the received information is responsive to light from the plurality of markers positioned at different corners of the boundary of the physical user collaborative area.

15. The non-transitory machine-readable storage medium of claim 13 , wherein the plurality of markers comprise a plurality of light emitters that transmit light signals encoded with different information, and wherein the instructions upon execution cause the system to:
determine the boundary based on the different information encoded in the transmitted light signals.

16. The non-transitory machine-readable storage medium of claim 13 , wherein the received information is responsive to light from the plurality of markers positioned at different corners o
