Abstract

Technologies for projecting a noncontinuous image onto at least a portion of a projection region using a projector of a projection device. The projection device is configured to determine one or more cut-out areas of the projection region. Each cut-out area defines an area within the projection region on which a corresponding portion of the image is not to be projected by the projector of the projection device. The projection device is further configured to update the projection region based on the cut-out area(s) and project, via the projector, the image onto the updated projection region, wherein no portion of the image is projected on cut-out area(s). Other embodiments are described and claimed.

First claim

The invention claimed is:

1. A projection device to project a noncontinuous image, the projection device comprising:
a projector to project an image onto a projection region, wherein the projection region defines a region on which the image is to be projected by the projector;
a projection initialization module to (i) determine a boundary of the projection region, (ii) determine at least one cut-out area of the projection region, wherein the at least one cut-out area defines an area within the projection region on which a corresponding portion of the image is not to be projected by the projector of the projection device, and (iii) generate an updated projection region based on the determined boundary of the projection region and the determined at least one cut-out area; and
a projection management module to project the image onto the updated projection region via the projector, wherein no portion of the image is projected on the at least one cut-out area.

2. The projection device of claim 1 , wherein to determine the boundary of the projection region comprises to perform, using a camera of the projection device, a depth scan to identify the projection region in a field of view of the projector of the projection device.

3. The projection device of claim 1 , further comprising to adjust the boundary of the projection region, wherein adjusting the boundary of the projection region comprises to (i) perform a scan to detect one or more boundary defining objects, (ii) identify a location of each of the one or more boundary defining objects, wherein each location identifies a point along a new boundary of the projection region, and (iii) adjust the boundary of the projection region based on each of the identified locations.

4. The projection device of claim 1 , wherein to determine the at least one cut-out area of the projection region comprises to (i) perform a scan to detect one or more boundary defining objects, (ii) identify a location of each of the one or more boundary defining objects, wherein each location identifies a point along the cut-out area, and (iii) generate the cut-out area based on each of the identified locations.

5. The projection device of claim 1 , wherein to not project the portion of the projection region that corresponds to the cut-out area comprises to emit substantially no light from the projector onto the cut-out area of the projection region.

6. The projection device of claim 1 , further comprising an action area determination module to (i) determine an action area of the projection region, wherein the action area defines an area within the projection region on which the image is to be projected by the projector of the projection device in response to a determination that a function associated with the action area is triggered, (ii) perform a scan to determine an action area boundary of the action area, wherein the action area boundary of the action area defines at least one of the size and shape of the action area, (iii) determine the action area boundary of the action area based on the scan, (iv) create an action area based on the determined action area boundary of the action area, and (v) store data identifying the action area.

7. The projection device of claim 6 , wherein the action area determination module is further to (i) determine the function to associate with the action area, (ii) determine one or more settings of the function, wherein the one or more settings include one or more environment conditions of an environment of the projection region, and wherein the environment conditions define a trigger that, when satisfied, cause the projection device to perform the function, and (iii) store the function of the action area and the one or more settings of the function.

8. The projection device of claim 7 , wherein to determine the one or more environment conditions comprises to monitor one or more sensors of the projection device to detect the environment conditions.

9. The projection device of claim 8 , further comprising an action area function performance module to perform an action based on a determination that the function associated with the action area is triggered, wherein the action comprises at least one of projecting the image onto the action area and playing back an audio file during at least a portion of the image projection.

10. The projection device of claim 1 , wherein the projection management module is further to (i) determine one or more settings of the projector based on the updated projection region and (ii) calibrate the projector based on the one or more projector settings.

11. The projection device of claim 10 , wherein the projection management module is further to (i) adjust the image to be projected based on the updated projection region and (ii) project the adjusted image onto the updated projection region.

12. One or more non-transitory, computer-readable storage media comprising a plurality of instructions stored thereon that in response to being executed cause a projection device to:
determine a boundary of a projection region, wherein the projection region defines a region on which an image is to be projected by a projector of the projection device;
determine at least one cut-out area of the projection region, wherein the at least one cut-out area defines an area within the projection region on which a corresponding portion of the image is not to be projected by the projector of the projection device;
generate an updated projection region based on the determined boundary of the projection region and the determined at least one cut-out area; and
project, by the projector, the image onto the updated projection region, wherein no portion of the image is projected on the at least one cut-out area.

13. The one or more non-transitory, computer-readable storage media of claim 12 , wherein to determine the boundary of the projection region comprises to perform, using a camera of the projection device, a depth scan to identify the projection region in a field of view of the projector of the projection device.

14. The one or more non-transitory, computer-readable storage media of claim 12 , further comprising a plurality of instructions that in response to being executed cause the projection device to adjust the boundary of the projection region, wherein to adjust the boundary of the projection region comprises to (i) perform a scan to detect one or more boundary defining objects, (ii) identify a location of each of the one or more boundary defining objects, wherein each location identifies a point along a new boundary of the projection region, and (iii) adjust the boundary of the projection region based on each of the identified locations.

15. The one or more non-transitory, computer-readable storage media of claim 12 , wherein to determine the at least one cut-out area of the projection region comprises to (i) perform a scan to detect one or more boundary defining objects, (ii) identify a location of each of the one or more boundary defining objects, wherein each location identifies a point along a cut-out area, and (iii) generate the cut-out area based on each of the identified locations.

16. The one or more non-transitory, computer-readable storage media of claim 12 , wherein to not project the portion of the projection region that corresponds to the cut-out area comprises emitting substantially no light from the projector onto the cut-out area of the projection region.

17. The one or more non-transitory, computer-readable storage media of claim 12 , further comprising a plurality of instructions that in response to being executed cau
