Abstract

This document describes authentication using an interactive cord. An interactive cord includes a cable, and a fabric cover that covers the cable. The fabric cover includes one or more conductive threads woven into the fabric cover to form one or more capacitive touchpoints which are configured to enable reception of touch input that causes a change in capacitance to the one or more conductive threads. The interactive cord can be used to authenticate a user. For example, rather than using a password entered into a computing device, a touch input pattern can be provided to interactive cord that is coupled to the computing device to authenticate the user.

Claims

1. A system comprising:

an interactive cord coupled to a headset that is communicatively coupled to a computing device, the interactive cord comprising a fabric cover, the fabric cover comprising one or more conductive threads woven into the fabric cover to form capacitive touchpoints on the fabric cover of the interactive cord; and

a controller coupled to the interactive cord and configured to control audio content to the headset from the computing device via the interactive cord, the controller further configured to;

detect a touch input pattern to one or more of the capacitive touchpoints of the fabric cover, the touch input pattern being based on a pattern of changes in capacitance to the one or more capacitive touchpoints;

compare the touch input pattern to a stored touch authentication pattern; and

authenticate the user to listen to the audio content from the computing device using the headset based on the touch input pattern matching the stored touch authentication pattern.

2. The system of claim 1, wherein the touch input pattern comprises tapping the one or more capacitive touchpoints with a particular rhythm.

3. The system of claim 1, wherein the touch input pattern comprises touching absolute positions of the one or more capacitive touchpoints on the fabric cover.

4. The system of claim 1, wherein the touch input pattern comprises touching relative positions of the one or more capacitive touchpoints on the fabric cover.

5. The system of claim 1, wherein the touch input pattern comprises applying a particular amount of pressure to the one or more capacitive touchpoints on the fabric cover.

6. The system of claim 1, wherein the touch input pattern comprises sliding from one capacitive touchpoint to another capacitive touchpoint.

7. The system of claim 1, wherein the touch input pattern comprises touching multiple capacitive touchpoints at substantially the same time.

8. The system of claim 1, wherein the touch input pattern comprises causing one capacitive touchpoint to touch one or more other capacitive touchpoints.

10. The system of claim 1, wherein the controller is integrated within the interactive cord and is configured to trigger, in response to the user being authenticated, an audio-playback function at a computing device communicatively coupled to the controller to allow the user to listen to the audio content using the headset.

11. The system of claim 1, wherein the controller is implemented at a computing device connected to the interactive cord.

9. An interactive cord for a headset, the interactive cord comprising:

an audio cable;

a fabric cover that covers the audio cable, the fabric cover comprising one or more conductive threads woven into the fabric cover to form capacitive touchpoints on the fabric cover of the interactive cord, the capacitive touchpoints configured to;

enable reception of a touch input pattern from a user based on a pattern of changes in capacitance to the one or more capacitive touchpoints; and

transmit the touch input pattern to a computing device connected to the interactive cord to authenticate the user; and

a controller configured to playback audio content at the headset when the touch input pattern matches a stored touch authentication pattern.

12. The interactive cord of claim 9, wherein the touch input pattern comprises tapping the one or more capacitive touchpoints with a particular rhythm.

13. The interactive cord of claim 9, wherein the touch input pattern comprises touching absolute positions of the one or more capacitive touchpoints on the fabric cover.

14. The interactive cord of claim 9, wherein the touch input pattern comprises touching relative positions of the one or more capacitive touchpoints on the fabric cover.

15. The interactive cord of claim 9, wherein the touch input pattern comprises applying a particular amount of pressure to the one or more capacitive touchpoints on the fabric cover.

16. The interactive cord of claim 9, wherein the touch input pattern comprises sliding from one capacitive touchpoint to another capacitive touchpoint.

17. The interactive cord of claim 9, wherein the touch input pattern comprises touching multiple capacitive touchpoints at substantially the same time or causing one capacitive touchpoint to touch one or more other capacitive touchpoints.

18. A method comprising:

detecting a touch input pattern to one or more capacitive touchpoints of a fabric cover of an interactive cord configured for data transfer, the touch input pattern being based on a pattern of changes in capacitance to the one or more capacitive touchpoints, the fabric cover comprising one or more conductive threads woven into the fabric cover to form the one or more capacitive touchpoints on the fabric cover of the interactive cord;

comparing the touch input pattern to a stored touch authentication pattern;

authenticating a user to access digital content at a computing device coupled to the interactive cord based on the touch input pattern matching the stored touch authentication pattern; and

enabling transfer of the digital content through the interactive cord responsive to authenticating the user.

19. The method of claim 18, wherein authenticating the user further comprises authenticating the user to transfer the digital content from the computing device to another computing device via the interactive cord.

20. The method of claim 18, wherein the touch input pattern comprises one or more of:

touching the one or more capacitive touchpoints with a particular rhythm;

touching absolute positions of the one or more capacitive touchpoints on the fabric cover;

touching relative positions of the one or more capacitive touchpoints on the fabric cover;

applying a particular amount of pressure to the one or more capacitive touchpoints on the fabric cover;

sliding from one capacitive touchpoint to another capacitive touchpoint;

touching multiple capacitive touchpoints at substantially the same time;

or

causing one capacitive touchpoint to touch one or more other capacitive touchpoints.
