Configuring your Tobii Pro X2 or X3 eye tracker for the Mobile Device Stand

The Tobii Mobile Device Stand is designed to be used with a Tobii Pro X2-30, X2-60, X3-120 Eye Trackers and a Windows computer running the Tobii Pro Studio Software. The Mobile Device Testing solution enables collection of eye tracking data during natural interaction with smartphones, tablet computers and other devices or objects of similar size such as books or brochures. The tested device (e.g. smartphone or tablet) is firmly attached to a supplied holder. The stand is delivered with all necessary equipment for eight different configurations optimized for different devices and setups. It includes an adjustable scene camera (that points at and films the mobile device) to enable capturing of user actions and the user interface. Eye tracking data will be superimposed on images and video captured with the scene camera in the analysis software, Tobii Pro Studio.

NOTE.

If the eye tracker is to be attached to a laptop to track the laptop screen, it must be reconfigured for the laptop screen by using the Tobii Eye Tracker Installer. If the eye tracker has only been unplugged, but not re-configured there is no need to use the X configuration tool when you plug in the eye tracker again. You can save and load saved configuration files using “Save to File” and “Load to File” in the X configuration tool.
