Pairing with companion device
Disclosed herein are systems and methods for device authentication or pairing. In an aspect, a wearable display system comprises a display, an image capture device configured to capture images of a companion device, a computer-readable storage medium configured to store the images of the companion device, and a processor in communication with the image capture device and the storage medium. The processor can be programmed with executable instructions to receive a first image of a first optical pattern displayed by the companion device captured by the image capture device, wherein the first optical pattern is generated by the companion device based on first shared data, extract first data from the first optical pattern in the received first image, authenticate the companion device based on the first data extracted from the first optical pattern, and notify a user of the wearable display system that the companion device is authenticated.
1. A head mounted display system comprising:
non-transitory computer-readable storage medium storing executable instructions; and
one or more processors in communication with the non-transitory computer-readable storage medium, the one or more processors programmed by the executable instructions to:
receive, from a first device, a request to authenticate a first connection between the first device and the head mounted display system, wherein the request comprises a first data that is a number encoded in a pattern of blinks displayed by two or more light-emitting devices on the first device, the two or more light-emitting devices including a first light-emitting device configured to emit light of a first color and a second light-emitting device configured to emit light of a second color, wherein the number is encoded in the pattern of blinks according to a predetermined protocol such that a first digit of the number corresponds to a number of blinks of the first light-emitting device in the first color and a second digit of the number corresponds to a number of blinks of the second light-emitting device in the second color;
extract the first data from the pattern of blinks;
transmit the first data to an authentication device that is configured to authenticate the first connection based at least in part on a first comparison of a first shared data received from the first device with the first data;
receive, from the authentication device, a confirmation of a successful authentication of the first connection that is based at least partly on determining a match between the first shared data and the first data; and
in response to receiving the confirmation of successful authentication of the first connection,
permit bi-directional communication of data between the first device and the head mounted display system, and
notify a user of the head mounted display system that the first connection has been authenticated.
2. The head mounted display system of claim 1 , wherein the first data is associated with the first shared data.
3. The head mounted display system of claim 1 , wherein the first device is configured to send the first shared data to an authentication device.
4. The head mounted display system of claim 1 , wherein the first comparison is based at least in part on a verification of consistency between the first shared data and the first data.
5. The head mounted display system of claim 1 , wherein the first device and the authentication device are different devices.
6. The head mounted display system of claim 1 , wherein the bi-directional communication of data between the first device and the head mounted display system is performed over a communication channel.
7. The head mounted display system of claim 1 , wherein the two or more light-emitting devices include one or more light-emitting diodes (LEDs).
8. The head mounted display system of claim 1 , wherein the authentication device is in communication with the head mounted display system and the first device over a cloud.
9. The head mounted display system of claim 1 , wherein the one or more processors are further programmed by the executable instructions to:
transmit an identifier of the head mounted display system to the authentication device.
10. The head mounted display system of claim 9 , wherein the authentication device authenticates the first connection based at least in part on the identifier.
11. The head mounted display system of claim 1 , wherein the request is generated by the first device.
12. The head mounted display system of claim 1 , wherein the first data is generated by the authentication device based at least in part on the first shared data.
13. The head mounted display system of claim 1 , wherein the first shared data comprises one or more of: an identifier of the first device; a spoken phrase; one or more spectral qualities of a spoken phrase; or biometric data of a user.
14. The head mounted display system of claim 1 , wherein the first device is a companion device that is configured to receive user input and, based on the user input, to provide commands to the head mounted display system using the first connection.
15. A method comprising:
receiving, from a first device, a request to authenticate a first connection between the first device and the head mounted display system, wherein the request comprises a first data that is a number encoded in a pattern of blinks displayed by two or more light-emitting devices on the first device, the two or more light-emitting devices including a first light-emitting device configured to emit light of a first color and a second light-emitting device configured to emit light of a second color, wherein the number is encoded in the pattern of blinks according to a predetermined protocol such that a first digit of the number corresponds to a number of blinks of the first light-emitting device in the first color and a second digit of the number corresponds to a number of blinks of the second light-emitting device in the second color;
extracting the first data from the pattern of blinks;
transmitting the first data to an authentication device that is configured to authenticate the first connection based at least in part on a first comparison of a first shared data received from the first device with the first data;
receiving, from the authentication device, a confirmation of a successful authentication of the first connection that is based at least partly on determining a match between the first shared data and the first data; and
in response to receiving the confirmation of successful authentication of the first connection,
permitting bi-directional communication of data between the first device and the head mounted display system, and
notifying a user of the head mounted display system that the first connection has been authenticated.
16. The method of claim 15 , wherein the first device is configured to send the first shared data to an authentication device.
17. The method of claim 15 , wherein the first comparison is based at least in part on a verification of consistency between the first shared data and the first data.
18. The method of claim 15 , wherein the first device and the authentication device are different devices.
19. The method of claim 15 , wherein the bi-directional communication of data between the first device and the head mounted display system is performed over a communication channel.
20. The method of claim 15 , wherein the first device is a companion device that is configured to receive user input and, based on the user input, to provide commands to the head mounted display system using the first connection.
