For many studies, presenting pictures or videos is not sufficient to produce realistic study conditions. On the other hand, direct investigation outside the laboratory can sometimes only be realized at considerable cost and expense, or may not be possible at all for various reasons.

Picture of a virtual shopping mall

Virtual environments offer an alternative to real-world settings. Using the Unity3D engine, controlled environments can be provided. Your subjects can move independently and interact with virtual items. The eye tracker is kept in sync with the current environment, and areas of interest are replaced by three-dimensional objects of interest.

The example shows a virtual shopping mall in which the user can move independently. The eye tracker identifies the objects on which the gaze is focused. These data are stored for later analysis.

Of course, these studies can be complemented by measuring physiological variables with the help of our recording systems.
