Abstract

Example implementations relate to a projector and an electronic ink display. For example, a system may include an electronic ink display device and a projector device. The electronic ink display device may display first content, and the projector device may project second content onto the electronic ink display device such that the second content is overlaid on the first content.

Claims

1. A system, comprising:

an electronic ink display device to display first content; and

a projector device to project second content onto the electronic ink display device such that the second content is overlaid on the first content.

2. The system of claim 1, wherein the electronic ink display device is in communication with the projector device wirelessly or through a wired connection.

3. The system of claim 1, wherein the electronic ink display device and the projector device are separate devices or are included in one device.

4. The system of claim 1, wherein the first content is associated with the second content.

5. The system of claim 1, further comprising:

a processor in communication with the electronic ink display device and the projector device, wherein the processor is to send the first content to the electronic ink display device and wherein the processor is to send the second content to the projector device.

6. The system of claim 5, wherein the processor is further to coordinate a display of the first content with a display of the second content.

7. A method, comprising:

identifying, by a computing device, content to be displayed on an electronic ink display device;

causing, by the computing device, a first portion of the content to be displayed by the electronic ink display device; and

causing, by the computing device, a second portion of the content to be projected onto the electronic ink display device by a projector device such that the second portion is overlaid on the first portion.

8. The method of claim 7, wherein the electronic ink display device and the projector device are in communication with the computing device wirelessly or through a wired connection.

9. The method of claim 7, wherein the first content is associated with the second content.

10. The method of claim 7, further comprising:

coordinating, by the computing device, a display of the first content with a display of the second content.

11. A non-transitory machine-readable storage medium storing instructions that, when executed by a processor of a computing device, cause the computing device to:

access content to be displayed on an electronic ink display device;

send a first portion of the content to the electronic ink display device, wherein the electronic ink display device is to display the first portion; and

send a second portion of the content to a projector device, wherein the projector device is to project the second portion onto the electronic ink display device such that the second portion is overlaid on the first portion.

12. The non-transitory machine-readable storage medium of claim 11, wherein the electronic ink display device and the projector device are in communication with the computing device wirelessly or through a wired connection.

13. The non-transitory machine-readable storage medium of claim 11, wherein the first content is associated with the second content.

14. The non-transitory machine-readable storage medium of claim 11, wherein the electronic ink display device and the projector device are separate devices or are included in one device.

15. The non-transitory machine-readable storage medium of claim 11, wherein the instructions further cause the computing device to coordinate a display of the first content with a display of the second content.
