Abstract

Systems and methods described herein provide tactile challenge-response tests for limiting access to electronic resources associated with a computing system. receiving, When a user requests access an electronic resource, the system activates an alternating voltage in an electrode layer for a display associated with the system to generate an electrovibrational pattern on the display and prompting the user to perform a touch gesture upon the affected region of the display to allow the user to perceive the electrovibrational pattern via the user'"'"'s sense of touch. Next, the computing system renders multiple different visual patterns on the display and prompts the user to select the visual pattern that matches the electrovibrational pattern. If the user correctly selects the visual pattern that matches the electrovibrational pattern, the system allows the user to access the electronic resource.

Claims

1. A system comprising:

one or more processors; and

a memory storing instructions that, when executed on the one or more processors, perform a set of actions, the set of actions comprising;

receiving, via an input/output (I/O) peripheral associated with a computing device, a request from a user to access an electronic resource;

activating an alternating voltage in an electrode layer for a display associated with the computing device to generate an electrovibrational pattern in a first region of the display;

prompting the user to perform a touch gesture upon the first region of the display to allow the user to perceive the electrovibrational pattern;

detecting that the user has completed performing the touch gesture;

rendering a plurality of different visual patterns on a plurality of corresponding regions the display, wherein one of the visual patterns matches the electrovibrational pattern;

prompting the user to identify which of the visual patterns matches the electrovibrational pattern;

receiving a selection from the user indicating which of the different visual patterns the user has selected as a match for the electrovibrational pattern; and

determining whether to allow the user to access the electronic resource based on the selection.

2. The system of claim 1, wherein the set of actions further comprises:

detecting that the selection correctly identifies the visual pattern that matches the electrovibrational pattern; and

allowing the user to access the electronic resource via the computing device.

3. The system of claim 1, wherein the set of actions further comprises:

detecting that the selection does not correctly identify the visual pattern that matches the electrovibrational pattern; and

preventing the user from accessing the electronic resource via the computing device.

4. The system of claim 1, wherein the display comprises an insulating layer positioned between the electrode layer and a surface of the display upon which the user performs the touch gesture.

5. The system of claim 1, wherein the set of actions further comprises:

for each visual pattern, activating an alternating voltage in the electrode layer beneath the corresponding region of the display on which the visual pattern is rendered to generate a corresponding electrovibrational pattern that that matches the visual pattern to create a sensation of a texture on the visual pattern when the user performs the touch gesture.

6. The system of claim 1, wherein:

the request from the user is received via a microphone;

prompting the user to perform the touch gesture comprises providing initial audio instructions to the user via a speaker; and

prompting the user to identify which of the visual patterns matches the electrovibrational pattern comprises providing additional audio instructions to the user via the speaker.

7. The system of claim 1, wherein the visual patterns comprise one or more of:

a zig zag, a plurality of parallel horizontal lines, a plurality of parallel vertical lines, or a plurality of dots.

20. The non-transitory computer-readable storage medium of claim 1, wherein:

the request from the user is received via a microphone;

prompting the user to perform the touch gesture comprises providing initial audio instructions to the user via a speaker; and

prompting the user to identify which of the visual patterns matches the electrovibrational pattern comprises providing additional audio instructions to the user via the speaker.

8. A method comprising:

receiving, via an input/output (I/O) peripheral associated with a computing device, a request from a user to access an electronic resource;

activating an alternating voltage in an electrode layer for a display associated with the computing device to generate an electrovibrational pattern in a first region of the display;

prompting the user to perform a touch gesture upon the first region of the display to allow the user to perceive the electrovibrational pattern;

detecting that the user has completed performing the touch gesture;

rendering a plurality of different visual patterns on a plurality of corresponding regions the display, wherein one of the visual patterns matches the electrovibrational pattern;

prompting the user to identify which of the visual patterns matches the electrovibrational pattern;

receiving a selection from the user indicating which of the different visual patterns the user has selected as a match for the electrovibrational pattern; and

determining whether to allow the user to access the electronic resource based on the selection.

9. The method of claim 8, further comprising:

detecting that the selection correctly identifies the visual pattern that matches the electrovibrational pattern; and

allowing the user to access the electronic resource via the computing device.

10. The method of claim 8, further comprising:

detecting that the selection does not correctly identify the visual pattern that matches the electrovibrational pattern; and

preventing the user from accessing the electronic resource via the computing device.

11. The method of claim 8, wherein the display comprises an insulating layer positioned between the electrode layer and a surface of the display upon which the user performs the touch gesture.

12. The method of claim 8, further comprising:

for each visual pattern, activating an alternating voltage in the electrode layer beneath the corresponding region of the display on which the visual pattern is rendered to generate a corresponding electrovibrational pattern that that matches the visual pattern to create a sensation of a texture on the visual pattern when the user performs the touch gesture.

13. The method of claim 8, wherein:

the request from the user is received via a microphone;

prompting the user to perform the touch gesture comprises providing initial audio instructions to the user via a speaker; and

prompting the user to identify which of the visual patterns matches the electrovibrational pattern comprises providing additional audio instructions to the user via the speaker.

14. The method of claim 8, wherein the visual patterns comprise one or more of:

a zig zag, a plurality of parallel horizontal lines, a plurality of parallel vertical lines, or a plurality of dots.

15. A non-transitory computer-readable storage medium containing instructions thereon that, when executed on a processor, perform a set of actions comprising:

receiving, via an input/output (I/O) peripheral associated with a computing device, a request from a user to access an electronic resource;

activating an alternating voltage in an electrode layer for a display associated with the computing device to generate an electrovibrational pattern in a first region of the display;

prompting the user to perform a touch gesture upon the first region of the display to allow the user to perceive the electrovibrational pattern;
