Pausing device operation based on facial movement

1 . A method comprising:

monitoring, by a processor, user eye movement of a user of a head-wearable apparatus;

determining that the user eye movement is directionally facing away from a display device coupled to the head-wearable apparatus using a backwards facing camera coupled to the head-wearable apparatus;

based on the determination by the backwards facing camera that the user eye movement is directionally facing away from the display device, automatically pausing operation of a graphics processing unit (GPU) and a front-facing camera coupled to the head-wearable apparatus;

while the GPU and the front-facing camera are paused, continuing the monitoring of the user eye movement using the backwards facing camera;

detecting that the user eye movement has returned to directionally face towards the display device; and

in response to detecting that the user eye movement has returned to directionally face towards the display device, automatically resuming operation of the GPU and the front-facing camera.

2 . The method of claim 1 , wherein monitoring the user eye movement comprises:

capturing the user eye movement using the backwards facing camera coupled to the head-wearable apparatus.

3 . The method of claim 1 , wherein monitoring the eye movement comprises:

detecting a reflection of infrared light from the user's eye using the backwards facing camera, the backwards facing camera being an infrared camera coupled to the head-wearable apparatus.

4 . The method of claim 1 , further comprising:

pausing operation of one or more sensors of the head-wearable apparatus, wherein the one or more sensors comprise a motion sensor, a rotation sensor, an orientation sensor, a position sensor, or any combination thereof.

5 . The method of claim 1 , wherein the front-facing camera is facing away from the user of the head-wearable apparatus, the front-facing camera coupled to the head-wearable apparatus.

6 . The method of claim 1 , wherein determining the user eye movement is directionally facing away from the display device further comprises:

receiving data from the backwards facing camera facing the user of the head-wearable apparatus, the data comprising an indication that the user is not facing the display device.

7 . The method of claim 1 , further comprising:

causing display of an augmented reality content item on the display device;

determining that the user eye movement is directionally facing towards the display device; and

modifying the augmented reality content item being displayed on the display device.

8 . A computing system comprising:

a processor; and

a memory storing instructions that, when executed by the processor, configure the system to perform operations comprising:

monitoring user eye movement of a user of a head-wearable apparatus;

determining that the user eye movement is directionally facing away from a display device coupled to the head-wearable apparatus using a backwards facing camera coupled to the head-wearable apparatus;

based on the determination by the backwards facing camera that the user eye movement is directionally facing away from the display device, automatically pausing operation of a graphics processing unit (GPU) and a front-facing camera coupled to the head-wearable apparatus;

while the GPU and the front-facing camera are paused, continuing to the monitoring of the user eye movement using the backwards facing camera;

detecting that the user eye movement has returned to directionally face towards the display device; and

in response to detecting that the user eye movement has returned to directionally face towards the display device, automatically resuming operation of the GPU and the front-facing camera.

9 . The computing system of claim 8 , wherein monitoring the user eye movement comprises:

capturing the user eye movement using the backwards facing camera coupled to the head-wearable apparatus.

10 . The computing system of claim 8 , wherein monitoring the eye movement comprises:

detecting a reflection of infrared light from the user's eye using the backwards facing camera, the backwards facing camera being an infrared camera coupled to the head-wearable apparatus.

11 . The computing system of claim 8 , the operations further comprising:

pausing operation of one or more sensors of the head-wearable apparatus, wherein the one or more sensors comprise a motion sensor, a rotation sensor, an orientation sensor, a position sensor, or any combination thereof.

12 . The computing system of claim 8 , wherein the front-facing camera is facing away from the user of the head-wearable apparatus, the front-facing camera coupled to the head-wearable apparatus.

13 . The computing system of claim 8 , wherein determining the user eye movement is directionally facing away from the display device further comprises:

receiving data from the backwards facing camera facing the user of the head-wearable apparatus, the data comprising an indication that the user is not facing the display device.

14 . The computing system of claim 8 , further comprising:

causing display of an augmented reality content item on the display device;

determining that the user eye movement is directionally facing towards the display device; and

modifying the augmented reality content item being displayed on the display device.

15 . A non-transitory computer-readable storage medium, the computer-readable storage medium including instructions that when executed by a computer, cause the computer to perform operations comprising:

monitoring user eye movement of a user of a head-wearable apparatus;

determining that the user eye movement is directionally facing away from a display device coupled to the head-wearable apparatus using a backwards facing camera coupled to the head-wearable apparatus;

based on the determination by the backwards facing camera that the user eye movement is directionally facing away from the display device, automatically pausing operation of a graphics processing unit (GPU) and a front-facing camera coupled to the head-wearable apparatus;

while the GPU and the front-facing camera are paused, continuing to the monitoring of the user eye movement using the backwards facing camera;

detecting that the user eye movement has returned to directionally face towards the display device; and

in response to detecting that the user eye movement has returned to directionally face towards the display device, automatically resuming operation of the GPU and the front-facing camera.

16 . The computer-readable storage medium of claim 15 , wherein monitoring the user eye movement comprises:

capturing the user eye movement using the backwards facing camera coupled to the head-wearable apparatus.

17 . The computer-readable storage medium of claim 15 , wherein monitoring the eye movement comprises:

detecting a reflection of infrared light from the user's eye using the backwards facing camera, the backwards facing camera being an infrared camera coupled to the head-wearable apparatus.

18 . The computer-readable storage medium of claim 15 , the operations further comprising:

pausing operation of one or more sensors of the head-wearable apparatus, wherein the one or more sensors comprise a motion sensor, a rotation sensor, an orientation sensor, a position sensor, or any combination thereof.

19 . The computer-readable storage medium of claim 15 , wherein the front-facing camera is facing away from the user of the head-wearable apparatus, the front-facing camera coupled to the head-wearable apparatus.
