Abstract

Systems and methods for device handshaking are described. Embodiments for client device and associated wearable device initiated handshaking are described. In certain embodiments, a device such as wearable camera eyeglasses having both high-speed wireless circuitry and low-power wireless circuitry communicates with a client device. The low-power wireless circuitry is used for signaling and to manage power on handshaking for the high-speed circuitry in order to reduce power consumption. An analysis of a high-speed connection status may be performed by a client device, and used to conserve power at the glasses with signaling from the client device to indicate when the high-speed circuitry of the glasses should be powered on.

Claims

1. A method comprising:

verifying, by a client device, an established low-power wireless connection from the client device to a wearable camera device;

communicating via the low-power wireless connection, a new data query;

receiving, from the wearable camera device in response to the new data query, a new camera data message identifying first camera data stored on the wearable camera device;

performing, by the client device, a high-speed connection status check;

communicating, in response to the high-speed connection status check, a connection communication from the client device to the wearable camera device, wherein the connection communication instructs the wearable camera device to activate high-speed wireless circuitry of the wearable camera device;

establishing a high-speed wireless connection to the wearable camera device; and

receiving the first camera data via the high-speed wireless connection.

2. The method of claim 1 further comprising:

communicating, from the client device to the wearable camera device using the low-power wireless connection, a sleep-state communication instructing the wearable camera device to power down high-speed circuitry associated with the high-speed wireless connection.

3. The method of claim 2 wherein communication of the new data query is triggered by an application launch.

4. The method of claim 2 wherein communication of the new data query is triggered by a periodic data check timer.

5. The method of claim 2 wherein the high-speed connection is an Institute of Electrical and Electronics Engineers (IEEE) 802.11 (Wi-Fi) connection.

6. The method of claim 5 wherein communication of the new data query is triggered by identification of a network disconnect associated with Wi-Fi circuitry of the client device, wherein the high-speed connection is established using the Wi-Fi circuitry of the client device.

7. The method of claim 6 wherein the low-power connection is a Bluetooth low energy (LE) connection.

8. The method of claim 7 further comprising:

interrupting operation of an application prior to establishing the high-speed wireless connection; and

resuming operation of the application following reception of the first camera data.

9. The method of claim 2 further comprising:

establishing the low-power wireless connection using a background process operating on the client device.

10. The method of claim 2 wherein the high-speed connection status check comprises a high-speed connection success prediction made by the client device.

11. The method of claim 10 wherein the high-speed connection success prediction by the client device indicates a threshold likelihood of connection success based on a current use status of client-device high-speed wireless circuitry.

12. The method of claim 11 wherein the high-speed connection success prediction is further based on a client device user input received in response to a user prompt presented at a display of the client device.

13. The method of claim 2 further comprising:

receiving, prior to establishing the high-speed wireless connection, a connection unsuccessful communication associated with the high-speed wireless connection from the wearable camera device; and

communicating a network adjustment command from the client device to the wearable camera device via the low-power wireless connection.

14. The method of claim 2 further comprising, after powering down the high-speed processor and the high-speed wireless circuitry after completion of the communication of the first camera data to the client device:

communicating via the low-power wireless connection, a second new data query;

receiving, from the wearable camera device in response to the second new data query, a second new camera data message identifying second camera data stored on the wearable camera device;

performing, by the client device, a second high-speed connection status check;

communicating, via the low-power wireless connection in response to the second high-speed connection status check, a second connection communication from the client device to the wearable camera device, wherein the second connection communication instructs the wearable camera device to activate the high-speed wireless circuitry of the wearable camera device.

15. The method of claim 14 further comprising:

failing to establishing the high-speed wireless connection within a threshold time period; and

communicating, from the client device to the wearable camera device using the low-power wireless connection, a second sleep-sleep state communication instructing the wearable camera device to power down high-speed circuitry without receiving the second camera data at the end of the threshold time period.
