Samsung patents eye-tracking 3D mapping that focuses on what you see

Samsung describes a device that uses two cameras to build a 3D map of its surroundings. One camera captures the environment while the other tracks where the user is looking. The system maps the area you are staring at in high detail and the rest of the room in lower detail to save processing power.

Why it mattersThis approach could make augmented reality experiences smoother by prioritizing the visual details that matter most to the user's attention.

In the filing’s own words

An electronic device and method are disclosed. The electronic device includes a first and second camera, display, memory and processor. The processor implements the method, including acquiring image data of an external environment via the first camera, detecting a plurality of objects included in the image data, identifying a first object corresponding to the detected gaze among the detected plurality of objects, configuring a first precision for spatial mapping of the identified first object and a second precision of at least one other object from among the detected plurality of objects, wherein the first precision is higher than the second precision, executing 3D spatial mapping on the image data using the first precision for the identified first object and the second precision for the at least one other object, and displaying a 3D space generated based on the image data and the spatial mapping.

What exactly they claim (claim 1)

1. An electronic device, comprising: a first camera; a second camera; a display; memory storing instructions; and a processor, wherein the instructions, when executed by the processor, cause the electronic device to: acquire, via the first camera, image data representing surrounding environments of the electronic device, detect, via the second camera, a gaze of a user, identify a first region corresponding to the detected gaze in the image data, perform 3-dimensional (3D) spatial mapping on the acquired image data by applying a first spatial mapping precision to the identified first region and a second spatial mapping precision to a second region other than the first region, wherein the second spatial mapping precision is lower than the first spatial mapping precision, and display, on the display, a 3D image generated based on the performed 3D spatial mapping.
