Modular computing device

1. A computing device comprising a plurality of modular components physically and communicatively coupled one to another, the plurality of modular components including at least:

a display modular component including a display housing, a display device physically and communicatively coupled to the display housing, and one or more display hardware elements disposed within the display housing and configured to output a display for display by the display device;

a computing modular component including a processing system disposed within a computing housing, and memory disposed within the computing housing, the processing system configured to execute instructions stored by the processing system to generate a user interface for display by the display device of the display modular component; and

at least one accessory modular component physically and communicatively coupled to the computing device.

2. A computing device as described in claim 1 , wherein the at least one accessory modular component comprises a camera that is configured to capture images and communicate the images to the computing modular component to recognize one or more gestures.

3. A computing device as described in claim 2 , wherein the camera of is configured to rotate in cooperation with rotation of the display device.

4. A computing device as described in claim 1 , wherein at least one accessory modular component includes an accessory housing and accessory hardware elements disposed therein to support corresponding functionality.

5. A computing device as described in claim 1 , wherein the plurality of modular components is arranged in a stacked configuration.

6. A computing device as described in claim 1 , further comprising a magnetic coupling device to form a physical connection between at least two of the plurality of modular components.

7. A computing device as described in claim 1 , wherein the computing housing of the computing modular component is configured to removably receive a housing including the processing system disposed therein and a housing including the memory disposed therein, the housings including the processing system and the memory being swappable within the computing housing of the computing modular component by a user without using tools.

8. A computing device as described in claim 7 , wherein the computing housing of the computing modular component is configured to removably receive a housing including wireless communication device that is swappable within the computing housing of the computing modular component.

9. A computing device as described in claim 7 , wherein the housings including the processing system and the memory are physically and communicatively coupled to and within the computing housing of the computing modular component.

10. A computing device as described in claim 7 , wherein the housings including the processing system and the memory are physically and communicatively coupled to and within the computing housing of the computing modular component via one or more protrusions that are received via cavities to form a mechanical attachment.

11. A computing device as described in claim 10 , wherein the mechanical attachment is formed such that off-axis removal causes mechanical binding of the one or more protrusions within respective said cavities.

12. A computing device as described in claim 1 , wherein the display device is configured to support touchscreen functionality.

13. A computing device as described in claim 1 , wherein the display modular component is configured to support attachment to a vertical surface including a wall or a cart.

14. A computing device as described in claim 1 , wherein the display modular component further includes a processing system and memory configured to execute an operating system when separated from the computing modular component and the processing system of the memory of the computing modular component are configured to provide additional processing and memory resources to the display modular component when physically and communicatively coupled.

15. A system as described in claim 1 , comprising a plurality of modular components, each of the modular components having a respective housing configured to form a stackable arrangement, one to another, and configured to be physically and communicatively coupled to form a computing device.
