User detection and user attention detection using multi-zone depth sensing

An electronic device, comprising:

• an electronic display configured to enter a plurality of power usage modes;
• one or more depth sensors configured to detect a plurality of depths of a plurality of zones of a field of view of the one or more depth sensors;
• image generation logic configured to generate an image based on the plurality of depths of the plurality of zones;
• user attention detection logic configured to determine that a user is focused on the electronic device;
• display control logic configured to cause the electronic display to enter the plurality of power usage modes;
• and
• a controller comprising a processor and a memory, wherein the memory comprises machine-readable instructions configured to cause the processor to:
• receive the plurality of depths from the one or more depth sensors;
• instruct the image generation logic to generate the image based on the plurality of depths;
• instruct the user attention detection logic to determine that the user is focused on the electronic device based on the image;
• and
• instruct the display control logic to cause the electronic display to enter a power usage mode of the plurality of power usage modes in response to the user attention detection logic determining that the user is focused on the electronic device.

One or more tangible, non-transitory, machine-readable media, comprising machine-readable instructions that cause a processor to:

• receive a plurality of depth measurements from one or more depth sensors of an electronic device;
• generate an image based on the plurality of depth measurements;
• apply a first model to the image, wherein the first model is configured to determine that a user is present in a field of view of the one or more depth sensors;
• apply a second model to the image in response to the first model determining that the user is present in the field of view of the one or more depth sensors, wherein the second model is configured to determine that the user is focused on the electronic device based on the image;
• and
• cause an electronic display of the electronic device to enter a power usage mode in response to the second model determining that the user is focused on the electronic device based on the image.
