Abstract
Techniques for determining a user's IPD are described. A first stimulus is displayed on a first display, and a second stimulus is displayed on a second display. A stimulus separation distance is a distance that exists between the first and second stimuli. The stimulus separation distance is progressively increased by progressively moving, in opposing directions relative to one another, the first and second stimuli. While that distance is being progressively increased, at least one of the user's eyes is tracked. While the distance is being progressively increased, a change in a rate of eye movement for the user's eye is detected. When the change is detected, a value for the stimulus separation distance is recorded. The recorded value is set as a baseline for the user's IPD.
