摘要：
Devices and methods are provided for eye-tracking, e.g., including a freeform optical assembly and/or a modular design. In an exemplary embodiment, a device and method are provided that includes a wearable device on a user's head, the wearable device including a scene camera oriented to capture images of the user's surroundings. The user may perform a predetermined action with the user's eye to activate a photo feature of the wearable device, gaze at a region within the user's surroundings, the wearable device determining a focal point and limited field-of-view for the camera imaging field based on the center point, and activate the camera to capture an image of the limited field-of-view centered around the focal point.
