Unlocking a screen using eye tracking information

A non-transitory computer readable medium having stored thereon instructions executable by a computing device to cause the computing device to perform functions comprising:

• receiving eye tracking information associated with eye movement of a user of the computing device from an eye tracking system coupled to the computing device, wherein the computing device is in a first mode of operation;
• based on the eye tracking information, determining that a path associated with the eye movement substantially matches a path of a displayed moving object, wherein determining that the path associated with the eye movement substantially matches the path of the displayed moving object comprises adjusting the path associated with the eye movement based on a location of a gaze axis of an eye with respect to a reference axis associated with the eye tracking system;
• and
• in response to determining that the path associated with the eye movement substantially matches the path of the displayed moving object, causing the computing device to enter a second mode of operation, wherein the second mode of operation comprises a state of increased responsiveness to user-input as compared to the first mode of operation.

A system comprising:

• a wearable computer including a head-mounted display (HMD), wherein the wearable computer is operable to be in a first mode of operation;
• an eye tracking system in communication with the wearable computer, wherein the eye tracking system is configured to track eye movement of a user of the wearable computer;
• and
• a processor coupled to the wearable computer and in communication with the eye tracking system, wherein the processor is configured to:
• receive eye tracking information associated with the eye movement from the eye tracking system, wherein the processor is configured to adjust the eye tracking information based on a location of a gaze axis of an eye with respect to a reference axis associated with the HMD;
• based on the eye tracking information, determine that the eye movement is associated with reading a text displayed on the HMD;
• and
• in response to determining that the eye movement is associated with reading the text, cause the wearable computer to enter a second mode of operation, wherein the second mode of operation comprises a state of increased responsiveness to user-input as compared to the first mode of operation.
