Abstract

In some implementations, a transaction device may include a display screen, at least one photosensitive sensor configured to detect a luminance of a viewing surface of the display screen, and one or more processors. The one or more processors may be configured to monitor an output of the at least one photosensitive sensor, determine that the output is indicative of an obstruction on the display screen based on the output indicating a change to the luminance of the viewing surface of the display screen, and disable one or more operations of the transaction device based on determining that the output is indicative of the obstruction on the display screen.

First claim

What is claimed is:

1. A device capable of obstruction detection, the device comprising:
a display screen;
one or more photosensitive sensors configured to detect a luminance of a viewing surface of the display screen; and
one or more processors configured to:
determine a threat level based on an output of the one or more photosensitive sensors indicating a change to the luminance of the viewing surface of the display screen; and
perform one or more actions associated with one or more operations of the device based on the threat level.

2. The device of claim 1 , wherein the threat level is associated with an obstruction determined based on the output.

3. The device of claim 1 , wherein the one or more processors, to determine the threat level, are configured to:
determine the threat level based on the output being associated with a particular pattern of the luminance being detected across the one or more photosensitive sensors.

4. The device of claim 1 , wherein the one or more processors, to determine the threat level, are configured to:
determine that the output is indicative of an obstruction, and
determine the threat level based on a location of the obstruction.

5. The device of claim 1 , wherein the one or more processors, to determine the threat level, are configured to:
determine the threat level based on determining that the output is indicative of a particular object being placed on the display screen.

6. The device of claim 1 , wherein the one or more processors, to determine the threat level, are configured to:
determine the threat level based on an amount of time associated with the output.

7. The device of claim 1 , wherein performing the one or more actions comprises:
disabling the one or more operations of the device.

8. A non-transitory computer-readable medium storing a set of instructions, the set of instructions comprising:
one or more instructions that, when executed by one or more processors of a device, cause the device to:
determine a threat level based on an output of one or more photosensitive sensors indicating a change to a luminance of a viewing surface of a display screen of the device; and
perform one or more actions associated with one or more operations of the device based on the threat level.

9. The non-transitory computer-readable medium of claim 8 , wherein the threat level is associated with an obstruction determined based on the output.

10. The non-transitory computer-readable medium of claim 8 , wherein the one or more instructions, that cause the device to determine the threat level, cause the device to:
determine the threat level based on the output being associated with a particular pattern of the luminance being detected across the one or more photosensitive sensors.

11. The non-transitory computer-readable medium of claim 8 , wherein the one or more instructions, that cause the device to determine the threat level, cause the device to:
determine that the output is indicative of an obstruction, and
determine the threat level based on a location of the obstruction.

12. The non-transitory computer-readable medium of claim 8 , wherein the one or more instructions, that cause the device to determine the threat level, cause the device to:
determine the threat level based on determining that the output is indicative of a particular object being placed on the display screen.

13. The non-transitory computer-readable medium of claim 8 , wherein the one or more instructions, that cause the device to determine the threat level, cause the device to:
determine the threat level based on an amount of time associated with the output.

14. The non-transitory computer-readable medium of claim 8 , wherein the one or more instructions, that cause the device to perform the one or more actions, cause the device to:
disable the one or more operations of the device.

15. A method, comprising:
determining, by a device, a threat level based on an output of one or more photosensitive sensors indicating a change to a luminance of a viewing surface of a display screen of the device; and
performing, by the device, one or more actions associated with one or more operations of the device based on the threat level.

16. The method of claim 15 , wherein the threat level is associated with an obstruction determined based on the output.

17. The method of claim 15 , wherein determining the threat level comprises:
determining the threat level based on the output being associated with a particular pattern of the luminance being detected across the one or more photosensitive sensors.

18. The method of claim 15 , wherein determining the threat level comprises:
determining that the output is indicative of an obstruction, and
determining the threat level based on a location of the obstruction.

19. The method of claim 15 , wherein determining the threat level comprises:
determining the threat level based on determining that the output is indicative of a particular object being placed on the display screen.

20. The method of claim 15 , wherein determining the threat level comprises:
determining the threat level based on an amount of time associated with the output.
