Tobii Game Hub and the games in the Tobii Game Hub use eye tracking, not eye control. For example, you may get a broader field of view in a game when using Tobii Gaming's eye tracking. Tobii Dynavox Control uses eye tracking to control the user's computer environment. Eye control is very different from eye tracking and the two should not be confused. Other places where eye tracking is used may be in a car to determine if the user is falling asleep or in marketing surveys to determine what products the user is looking at. Tobii Gaming gets an idea of where the user is looking to expand the functionality of games but not to control them.
