We have not studied if changing eye orientation relative to the head changes gaze-related activity in the GF patch in monkeys.
"You did not have to change your gaze angle much to see it," Dr. Kun said.
CosmoBot is a Wizard of Oz robot that is externally controlled by a therapist; it has an elliptical head and the ability to swivel, in order to change its gaze.
But if they change their gaze to focus on the paper, the glasses immediately adjust the lenses (perhaps independently per eye) to bring that object into focus in a way that doesn't strain the person's eyes.
Change in gaze direction is one of several behavioral cues that individuals use in combination with changes in facial and vocal displays and body posture to mark the intention to act on an object.
When this unique stimulus translates across their visual field, neurotypical infants will change their gaze or head direction to track the protoface [1 3].
In autism spectrum conditions (ASCs), a group of neurodevelopmental conditions characterized by difficulties in social interactions and communication alongside unusually narrow interests and resistance to change, direct gaze does not confer these same perceptual benefits.
VirtualEye performs the equivalent of a full threshold 24-2 visual field in two modes: (1) manual, with patient response registered with a mouse click, and (2) visual grasp, where the eye tracker senses change in gaze direction as evidence of target acquisition.
The changes in viewpoint correspond to changes in gaze direction, which is often signaled in real life by movements of both eyes and head (Bruce and Young 2012).
For instance, rapid changes of gaze direction require fast cervical rotations if the magnitude of gaze change is large.
