Method and System for Dwell-less, Hands-free Interaction with a Selectable Object
11 Feb 21
Disclosed is a method for interacting with a selectable object displayed by means of a displaying device, the method comprising the steps of: obtaining a gaze convergence distance and a gaze direction of a user, the gaze direction lying in a field of view defined by the displaying device; determining whether the gaze direction coincides with the selectable object; and if so, detecting a change in the gaze convergence distance; and if the detected change in the gaze convergence distance exceeds a predetermined threshold value interacting with the selectable object.
