If the user's gaze is directed to the principal object beyond a threshold criterion, a previously removed secondary object is reintroduced into the scene. The principal object is a desired object of the user's attention, while the secondary object(s) may be potentially or known distracting objects. Corresponding software and methods are also disclosed.
