Saccade contingent updating in virtual reality
The overall pattern of results is consistent with the hypothesis that subjects typically rely on mechanisms that are initiated top–down to detect unexpected events such as potential collisions.For this to be effective, subjects must learn an appropriate schedule for initiating search through experience with the probabilities of environmental events.Eye tracking is the process of measuring either the point of gaze ("where we are looking") or the motion of an eye relative to the head.An eye tracker is a device for measuring eye positions and eye movement.Virtual reality (VR), is a term that applies to computer-simulated environments that can simulate physical presence in places in the real world, as well as in imaginary worlds.Most current virtual reality environments are primarily visual experiences, displayed either on a computer screen or through special stereoscopic displays, but some simulations include additional sensory information, such as sound through speakers or headphones.is working on new features that could fix some of that.Unfortunately, it might involve hanging out in the VR version of a You Tube comments section.
However, a critical problem for task-driven systems is dealing with unexpected stimuli.In the new version of Daydream, called Euphrates, you can broadcast what you see in virtual reality to a regular TV over a Chromecast.That way any friends or family members hanging out in your home can see what you see.A saccade is a fast movement of an eye, head or other part of an animal's body or of a device.It can also be a fast shift in frequency of an emitted signal or other quick change.
