Guided object targeting based on physiological feedback

A system comprising:

• a processor;
• and
• a computer-readable storage medium storing instructions which, when executed by the processor, cause the system to:
• based at least on a user attention signal, identify a predicted object that a user intends to target;
• output an identification of the predicted object;
• receiving a user reaction signal conveying an implicit physiological reaction of the user to the identification of the predicted object;
• in an instance when the user reaction signal indicates that the predicted object is erroneous;
• identify another predicted object that the user intends to target;
• and
• perform a selection action on the another predicted object responsive to a selection input.

A computer-readable storage medium storing instructions which, when executed by a computing device, cause the computing device to perform acts comprising:

• receiving a user attention signal conveying where a user directs attention;
• based at least on the user attention signal, identifying a predicted object that the user intends to target with a targeting mechanism;
• outputting a visual identification of the predicted object;
• receiving a user reaction signal conveying an implicit physiological reaction of the user to the visual identification of the predicted object;
• and
• in an instance when the implicit physiological reaction of the user indicates an error, identifying another predicted object that the user intends to target with the targeting mechanism.
