Eye tracking wearable devices and methods for use

A method for taking a digital photo, comprising:

• activating, at a wearable device comprising a scene camera oriented to capture images of a user's surroundings, a photo feature of the wearable device in response to the user gazing at a predetermined location of the wearable device;
• determining, by the wearable device, in response to the user gazing at opposite corners of a virtual frame of a region within the user's surroundings, a focal point and limited field-of-view for an imaging field of the camera based on a center point and based upon the opposite corners;
• and
• capturing an image of the limited field-of-view centered around the focal point.

A device for taking a digital photo, comprising:

• a wearable device configured to be worn on a user's head;
• an endo-camera on the wearable device configured to obtain eye tracking images of the eye when the wearable device is worn by the user;
• an exo-camera on the wearable device configured to obtain images of the user's surroundings when the wearable device is worn by the user;
• and
• one or more processors coupled to the endo-camera configured to determine when the user performs a predetermined action with the user's eye to activate a photo feature of the wearable device, wherein the predetermined action comprises the user gazing at a Take Photo LED on the wearable device, the one or more processors coupled to the exo-camera configured to determine when the user gazes at a region within the user's surroundings in a predetermined manner, the one or more processors configured to determine a focal point and limited field-of-view for an imaging field of the exo-camera based on the predetermined manner, and to activate the exo-camera to capture an image of the limited field-of-view centered around the focal point.

• and
• capturing an image of the limited field-of-view centered around the focal point.

• and
• one or more processors coupled to the eye tracking camera and the scene camera to determine when the user gazes at a predetermined location of the wearable device to activate a photo feature of the wearable device and when the user gazes at opposite corners of a virtual frame of a region within the user's surroundings, the one or more processors configured to determine a focal point and a limited field-of-view for an imaging field of the camera based on the gazed-upon opposite corners and to activate the scene camera to capture an image of the limited field-of-view centered around the focal point.
