## Abstract

An example system includes a camera to capture an image of an object on a surface, and a projector unit, communicatively coupled to the camera, to project the image of the object on the surface. The camera simultaneously generates a first trigger to the projector unit to switch display modes and a second trigger to a lighting source to disable light being projected onto the surface in response to an instruction to initiate capture of the image of the object.

## Claims

### Claim 1

A system, comprising:
a camera to capture an image of an object on a surface: and
a projector unit, communicatively coupled to the camera, to project the image of the object on the surface;
wherein the camera simultaneously generates a first trigger to the projector unit to switch display modes and a second trigger to a lighting source to disable light being projected onto the surface in response to an instruction to initiate capture of the image of the object.

### Claim 2 (depends on 1)

The system of claim 1, further comprising a computing device, to provide the instruction to initiate the capture of the image of the object to the camera.

### Claim 3 (depends on 2)

The system of claim 2, wherein the computing device generates and sends a message to the camera, the message including instruction to initiate the capture of the image of the object.

### Claim 4 (depends on 2)

The system of claim 2, wherein the computing device receives a request to capture the image of the object via a control panel.

### Claim 5 (depends on 4)

The system of claim 4, wherein the control panel comprises control buttons including a capture button.

### Claim 6 (depends on 4)

The system of claim 4, wherein the control panel is embedded in the surface.

### Claim 7 (depends on 1)

The system of claim 1, wherein the lighting source is housed in the projector unit.

### Claim 8 (depends on 1)

The system of claim 1, wherein the projector unit switches back the display modes and the lighting source is enabled upon completion of capture of the image of the object.

### Claim 9 (depends on 2)

The system of claim 2, wherein the computing device is to cause the camera to scan the object on the surface to produce the image and then to cause the projector unit to project the image back on to the surface.

### Claim 10 (depends on 1)

The system of claim 1 further comprising an electrical connection between the surface and the computing device through a base.

### Claim 11

A processor-implemented method for managing a capture of an image of an object, comprising:
sending a message to a camera to initiate the capture of the image of the object, wherein in response to the message, the camera simultaneously provides a trigger to switch display mode of a projector, and another trigger to disable a lighting source;
receiving the image of the object; and
instructing to switch back the display mode of the projector, and to enable the lighting source.

### Claim 12 (depends on 11)

Thee processor-implemented method of claim 11, further comprising generating the message in response to a request to capture the image of the object.

### Claim 13 (depends on 12)

The processor-implemented method of claim 12, wherein the request is received via a control panel generated by a controller that the camera and projector are operatively connected.

### Claim 14

A system, comprising:
a projector unit attachable to project an image of an object on a touch sensitive mat;
a computing device attachable to he projector unit;
the touch sensitive mat communicatively coupled to the computing device; and
a camera, communicatively coupled to the computing device, to capture the image of the object on the touch sensitive mat, wherein the camera simultaneously generates a trigger to the projector unit to switch display modes and to disable light being projected onto the touch sensitive mat in response to an instruction to capture the image of the object.

### Claim 15 (depends on 14)

The system of claim 14, wherein the camera completes capturing the image of the object with limited interaction with the computing device.
