Abstract

A method of presenting content to a subject based on eye position measurements includes presenting the subject with content. While presenting the content to the subject, one or more of the subject's eye positions is measured, from which a locus of the subject's gaze is determined. The method includes continuously performing the operations of: generating an attention metric using the one or more measured eye positions; based on the attention metric, determining an attention state of the subject; and determining a trajectory of the locus of the subject's gaze. In accordance with detecting a change in the attention state of the subject, the presentation of the content is modified based on the trajectory of the locus of the subject's gaze so as to present different content than if the attention state of the subject had remained the not attending state.

Claims (143)

the presentation of the content is modified in accordance with detecting a change in the attention state of the subject from the not attending state to the attending state; and

the content is modified, based on the trajectory of the locus of the subject's gaze, so as to present different content than if the attention state of the subject had remained in the not attending state.

2. The method of claim 1 , wherein:

before detecting the change in the attention state of the subject, the content is provided statically; and

modifying the content comprises transitioning through the content at a rate corresponding to a numerical value of the attention metric.
