determining that the gaze direction is fixated.
9 . The method for causing an action to be performed by a device of claim 2 , wherein determining whether at least one of the gaze direction or the image data meets a condition comprises:
determining that the gaze direction is representative of a saccade of the eye of the user.
10 . The method for causing an action to be performed by a device of claim 2 , wherein determining whether at least one of the gaze direction or the image data meets a condition comprises:
determining that the gaze direction is in a particular direction.
11 . The method for causing an action to be performed by a device of claim 2 , wherein determining whether at least one of the gaze direction or the image data meets a condition comprises:
determining that the gaze direction has moved in a particular pattern.
12 . A system for causing an action to be performed by a device, wherein the system comprises:
an illuminator;
an image sensor; and
a device configured to at least:
cause the illuminator to illuminate at least a portion of an eye of a user;
receive image data from the image sensor representing images of at least a portion eye of the user;
determine at least one gaze direction of the user based at least in part on the image data;
determine whether at least one of the gaze direction or the image data meets a condition; and
cause a first action to be performed by the device based at least in part on a determination that at least one of the gaze direction or the image data meets the condition.
13 . The system for causing an action to be performed by a device of claim 12 , wherein causing the first action to be performed by the device is further based at least in part on a selection from a group consisting of:
actuation of a physical button; and
an audible input, including a sound or at least one word spoken by the user.
14 . The system for causing an action to be performed by a device of claim 12 , wherein determining whether at least one of the gaze direction or the image data meets a condition comprises a selection from a group consisting of:
determining that the gaze direction is fixated; and
determining that the gaze direction is in a particular direction.
15 . The system for causing an action to be performed by a device of claim 12 , wherein determining whether at least one of the gaze direction or the image data meets a condition comprises:
determining that the gaze direction is representative of a saccade of the eye of the user.
16 . The system for causing an action to be performed by a device of claim 12 , wherein determining whether at least one of the gaze direction or the image data meets a condition comprises:
determining that the gaze direction has moved in a particular pattern.
17 . A non-transitory machine readable medium having instructions stored thereon for causing an action to be performed by a device, the instructions executable by at least one processor to at least:
cause an illuminator to illuminate at least a portion of an eye of a user;
receive image data from an image sensor representing images of at least a portion eye of the user;
determine at least one gaze direction of the user based at least in part on the image data;
determine whether at least one of the gaze direction or the image data meets a condition; and
cause a first action to be performed by a device based at least in part on a determination that at least one of the gaze direction or the image data meets the condition.
18 . The non-transitory machine readable medium of claim 17 , wherein causing the first action to be performed by the device is further based at least in part on a selection from a group consisting of:
