Direction based user interface and digital sign display

1. A computing system, comprising:

a display device;

a pivot mechanism to pivot the display device in a number of facing directions;

a processor; and

one or more memory resources storing instructions that, when executed by the processor, cause the computing system to:

based on a first facing direction of the display device, initiate a first mode to display a cashier interface on the display device, the cashier interface enabling point of sale functions by which user entry of information is permitted on the display device;

detect a change from the first facing direction to a second facing direction by the display device;

in response to detecting the change to the second facing direction, initiate a second mode to display a digital sign image on the display device and disable user entry of information on the display device; and

in response to a user input on the digital sign image in the second facing direction, initiate a third mode to display a self-checkout interface enabling a customer to perform a retail transaction on the display device.

2. The computing system of claim 1 , wherein pivot mechanism comprises a ball joint enabling the pivot mechanism to pivot the display device about a vertical axis and rotate the display device about a horizontal axis, and wherein the executed instructions further cause the processor to:

select the displayed digital sign image from a group of digital sign images based on a rotated orientation of the display device about the horizontal axis.

3. The computing system of claim 1 , wherein the executed instructions further cause the processor to:

display the self-checkout interface in response to detecting a presence of the customer when the display device is in the second facing direction.

4. The computing system of claim 1 , wherein the executed instructions further cause the processor to:

after displaying the self-checkout interface in the second facing direction for a predetermined period of time without user input, select and display a second digital sign image on the display device.

5. The computing system of claim 1 , wherein the processor is to detect the change from the first facing direction to the second facing direction by the display device using a sensor device comprising at least one of a G-sensor, an accelerometer, an inclinometer, or a motion sensor, and wherein the executed instructions further cause the processor to:

using the sensor device, detect a change from the second facing direction to the first facing direction by the display device; and

in response to detecting the change to the first facing direction, display the cashier interface on the display device.

6. A method for displaying user interfaces, the method performed by one or more processors of a display device on a pivot mechanism, the method comprising:

based on a first facing direction of the display device, initiating a first mode to display a cashier interface on the display device, the cashier interface enabling point of sale functions by which user entry is permitted on the display device;

detecting a change from the first facing direction to a second facing direction by the display device;

in response to detecting the change to the second facing direction, initiating a second mode to display a digital sign image on the display device and disable user entry of information on the display device; and

in response to a user input on the digital sign image in the second facing direction, initiate a third mode to display a self-checkout interface enabling a customer to perform a retail transaction on the display device.

7. The method of claim 6 , wherein the pivot mechanism comprises a ball joint enabling the pivot mechanism to pivot the display device about a vertical axis and rotate the display device about a horizontal axis, the method further comprising:

selecting the displayed digital sign image from a group of digital sign images based on a rotated orientation of the display device about the horizontal axis.

8. The method of claim 6 , further comprising:

displaying the self-checkout interface in response to detecting a presence of the customer when the display device is in the second facing direction.

9. The method of claim 6 , further comprising:

after displaying the self-checkout interface in the second facing direction for a predetermined period of time without user input, selecting and displaying a second digital sign image on the display device.

10. The method of claim 6 , wherein detecting the change from the first facing direction to the second facing direction by the display device comprises using a sensor device comprising at least one of a G-sensor, an accelerometer, an inclinometer, or a motion sensor, the method further comprising:

using the sensor device, detecting a change from the second facing direction to the first facing direction by the display device; and

in response to detecting the change to the first facing direction, displaying the cashier interface on the display device.

11. A machine-readable non-transitory storage medium comprising instructions that, when executed by a processor of a display device on a pivot mechanism, cause the processor to:

based on a first facing direction of the display device, initiate a first mode to display a cashier interface on the display device, the cashier interface enabling point of sale functions by which user entry of information is permitted on the display device;

detect a change from the first facing direction to a second facing direction by the display device;

in response to detecting the change to the second facing direction, initiate a second mode to display a digital sign image on the display device and disable user entry of information on the display device; and

in response to a user input on the digital sign image in the second facing direction, initiate a third mode to display a self-checkout interface enabling a customer to perform a retail transaction on the display device.

12. The machine-readable non-transitory storage medium of claim 11 , wherein the pivot mechanism comprises a ball joint enabling the pivot mechanism to pivot display device about a vertical axis and rotate the display device about a horizontal axis, and wherein the executed instructions further cause the processor to:

select the displayed digital sign image from a group of digital sign images based on a rotated orientation of the display device about the horizontal axis.

13. The machine-readable non-transitory storage medium of claim 11 , wherein the executed instructions further cause the processor to:

display the self-checkout interface in response to detecting a presence of the customer when the display device is in the second facing direction.

14. The machine-readable non-transitory storage medium of claim 11 , wherein the executed instructions further cause the processor to:

after displaying the self-checkout interface in the second facing direction for a predetermined period of time without user input, selecting and displaying a second digital sign image on the display device.

15. The machine-readable non-transitory storage medium of claim 11 , wherein the processor is to detect the change from the first facing direction to the second facing direction by the display device using a sensor device comprising at least one of a G-sensor, an accelerometer, an inclinometer, or a motion sensor, and wherein the executed instructions further cause the processor to:

using the sensor device, detect a change from the second facing direction to the first facing direction by the display device; and

in response to detecting the change to the first facing direction, display the cashier interface on the display device.
