Sensor-based activation of an input device
First Claim
1. A method comprising:
- receiving, by one or more processors, a first signal from a first sensor of a mobile computing device, wherein the first signal represents a first action of a user of the mobile computing device, and wherein the mobile computing device is in a low power state in which a presence-sensitive screen is deactivated prior to receiving the first signal from the first sensor of the mobile computing device;
activating, based at least in part on the first signal, a second sensor of the mobile computing device;
receiving, by the one or more processors, a second signal from the second sensor, wherein the second signal represents a second action of the user of the mobile computing device;
activating, based at least in part on the first and second signals, an input device of the mobile computing device, wherein the input device comprises a microphone or a camera;
receiving, by the one or more processors, a first data sample captured by the input device;
determining, by the one or more processors, a captured template based at least in part on the first data sample, wherein the captured template comprises one or more features of the first data sample;
comparing, by the one or more processors, the captured template to a reference template, wherein the reference template comprises one or more features of a second data sample; and
responsive to determining that the captured template substantially matches the reference template, unlocking, by the one or more processors, the mobile computing device.

Abstract
A method can include receiving a first signal from a first sensor of a mobile computing device, where the first signal represents a first action of a user of the mobile computing device. In accordance with this example, the method further includes activating a second sensor of the mobile computing device based at least in part on the first signal. The method additionally can include receiving a second signal from the second sensor, where the second signal represents a second action of the user of the mobile computing device. The method further can include activating an input device of the mobile computing device based at least in part on the first and second signals. In some examples, the method may be implemented by one or more processors of a mobile computing device.

16. A mobile computing device comprising one or more processors, the one or more processors being configured to:
-
receive a first signal from a first sensor, wherein the first signal represents a first action of a user of the mobile computing device, and wherein the mobile computing device is in a low power state in which a presence-sensitive screen is deactivated prior to receiving the first signal from the first sensor of the mobile computing device; activate, based at least in part on the first signal, a second sensor; receive a second signal from the second sensor, wherein the second signal represents a second action of the user of the mobile computing device; and activate, based at least in part on the first and second signals, a camera and a presence-sensitive screen operatively coupled to the computing device; output, for display at the presence-sensitive screen, image or video data captured by the camera; receive a first data sample captured by the camera; determine a captured template based at least in part on the first data sample, wherein the captured template comprises one or more features of the first data sample; compare the captured template to a reference template, wherein the reference template comprises one or more features of a second data sample; and responsive to determining that the captured template substantially matches the reference template, unlock the mobile computing device. - View Dependent Claims (17, 18, 19, 20)

21. A non-transitory computer-readable storage medium comprising instructions that cause one or more processors to perform operations comprising:
-
receiving a first signal from a first sensor of a mobile computing device, wherein the first signal represents a first action of a user of the mobile computing, and wherein the mobile computing device is in a low power state in which a presence-sensitive screen is deactivated prior to receiving the first signal from the first sensor of the mobile computing device; activating, based at least in part on the first signal, a second sensor of the mobile computing device, the second sensor being different than the first sensor; receiving a second signal from the second sensor, wherein the second signal represents a second action of the user of the mobile computing device; activating, based at least in part on the second signal, a third sensor of the mobile computing device, the third sensor being different than the first sensor and different than the second sensor; receiving a third signal from the third sensor, wherein the third signal represents a third action of the user of the mobile computing device; activating, based at least in part on the first signal, the second signal, and the third signal, a camera of the mobile computing device; receiving a first data sample captured by the camera; determining a captured template based at least in part on the first data sample, wherein the captured template comprises one or more features of the first data sample; comparing the captured template to a reference template, wherein the reference template comprises one or more features of a second data sample; and responsive to determining that the captured template substantially matches the reference template, unlocking the mobile computing device. - View Dependent Claims (22, 23, 24)
