Real World Viewing / Scene Camera

An important area of eye movement research investigates how humans naturally look around the real world. With the use of a Scene Camera, eye position can be overlaid on a video of the observer’s view of the world. Such recordings can then be analyzed to understand how an observer’s eye movements guide their behaviour in a real-world setting.

The EyeLink II plus Scene Camera allows:
  • The EyeLink II to become a multifunction eye tracker – functioning within the normal laboratory method of stimulus delivery by computer monitor or moving the participant into a more naturalistic setting where interaction with others or with objects in the world becomes possible.
  • correction of parallax errors by using binocular disparity information. Parallax error is a commonly exhibited issue by other head-mounted eye trackers with a scene camera when viewing objects at different distances.
  • both a digital recording of eye movements with high-speed and precision, and a video recording of those same eye movements overlaid on the observer’s world view.
