User focus activated voice recognition

1. A method, comprising:

receiving, at a device, voice input comprising at least one command;

thereafter identifying, using an image of the user, a direction of user focus, wherein the direction of user focus is identified as not being directed toward the device;

detecting a shift in user focus directed toward the device after the voice input is at least partially received; and

responsive to detecting the shift in user focus, performing an action based on the at least one command.

2. The method of claim 1 , wherein the image of the user is derived using at least one sensor; and

wherein the at least one sensor is selected from a group consisting of: an image capture device, a video capture device, a range imaging device, and a 3D scanning device.

3. The method of claim 1 , wherein the identifying a direction of user focus is based on a head location of the user.

4. The method claim 1 , wherein the identifying a direction of user focus is based on a gaze location of a user.

5. The method of claim 1 , wherein the image of the user is derived from a plurality of sensors.

6. The method of claim 1 , further comprising:

placing the device in a low power state based on identifying that the direction of user focus is not directed toward the device for a predetermined time.

7. The method of claim 1 , further comprising

waking up the device from a low power state based on identifying that the direction of user focus is directed toward the device.

8. The method of claim 1 , further comprising changing a visual characteristic of the audio capture device in response to the user focus being directed toward device.

9. The method of claim 1 , further comprising playing an audible notification in response to the user focus being directed toward the device.

10. An information handling device, comprising:

a processor;

an audio capture device operatively coupled to the processor; and

a memory that stores instructions executable by the processor to:

receive, at the audio capture device, voice input comprising at least one command;

thereafter identify, using an image of the user, a direction of user focus, wherein the direction of user focus is identified as not being directed toward the device;

detect a shift in user focus directed toward the device after the voice input is at least partially received; and

responsive to detecting the shift in user focus, performing an action based on the at least one command.

11. The information handling device of claim 10 , wherein the image of the user is derived using at least one sensor; and

wherein the at least one sensor is selected from a group consisting of: an image capture device, a video capture device, a range imaging device, and a 3D scanning device.

12. The information handling device of claim 10 , wherein the identifying a direction of user focus is based on a head location of the user.

13. The information handling device claim 10 , wherein the identifying a direction of user focus is based on a gaze location of a user.

14. The information handling device of claim 10 , wherein the image of the user is derived from a plurality of sensors.

15. The information handling device of claim 10 , wherein the instructions are further executable by the processor to:

place the information handling device in a low power state based on identifying that the direction of user focus is not directed toward the information handling device for a predetermined time.

16. The information handling device of claim 10 , wherein the instructions are further executable by the processor to:

wake up the information handling device from a low power state based on identifying that the direction of user focus is directed toward the information handling device.

17. The information handling device of claim 1 , wherein the instructions are further executable by the processor to:

change a visual characteristic of the audio capture device in response to the user focus being directed toward the audio capture device.

18. A product, comprising:

a storage device having code stored therewith, the code being executable by the processor and comprising:

code that receives, at a device, voice input comprising at least one command;

code that thereafter identifies, using an image of the user, a direction of user focus, wherein the direction of user focus is identified as not being directed toward the device

code that detects a shift in user focus directed toward the device after the voice input is at least partially received; and

code that performs, responsive to detecting the shift in user focus, an action based on the at least one command.
