The examiner uses the Laptop, and the student sits in front of the external display which has an eye tracker mounted underneath.

Eye Tracker

Lexplore requires using Tobii 4C Eye tracker. This device is connected to the laptop with USB 2.0. It’s mounted to the external display with a magnet.

An eye tracker uses infrared light that makes it possible for a computer know where a person is looking. An eye tracker can detect the presence, attention and focus of the user.

Lexplore requires installation of Tobii Service Software for the eye tracker to work. This is an MSI package which requires Administrative privileges to install. We recommend our customers to distribute this through a software centre.

Screens

The student sits in front of the screen. The distance between the student and the screen must be 50-80cm. It’s important that you are able to adjust the angel and hight of the screen in order for the eye tracker to work properly. Hence, the monitor stand should be quick and easy to the examiner to adjust for each student. It should be possible to tilt the monitor a little bit forward.

The mounting magnet for the eye tracker is sealed on the bottom of the screen’s frame.

The Laptop must have a suitable connection to the screen. We recommend HDMI, but other digital connections are also possible as long as the resolution is fulfilled.
