About 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.

  2. Open the Tobii Eye Tracker Browser: Open the Windows Start Menu and type “Tobii Eye Tracker Browser” in the search field.
  3. In the search results list click “Tobii Eye Tracker Browser”. (You can also find it in the program list: All programs>Tobii).
  4. In the eye tracker browser dialog, select the eye tracker. If the eye tracker does not show up in the browser you may have to first run the Tobii Pro Eye Tracker installer. To open the configuration tool, click “Config tool”. If the X configuration tool does not open, please install the latest Eye Tracker Browser (available from download section).
  5. Locate the configuration you have assembled (A1, A2, B1, B2, C1, C2, D1 or D2) in the illustration that shows the eight different mobile device stand configurations. The standard configurations are A1 and A2 if you are using the flat holder, or B1 and B2 if you are using the bracket holder. In standard scenarios, configurations A1 and A2 are recommended for most tablets and smart phones.
  6. Enter the values for the eye tracker that correspond to your specific configuration (A, B, C or D) in the X Configuration Tool. The table below shows the values for all configurations. The figure below indicates where to put the values in the X Configuration Tool. Make sure Units is set to cm: all angles are measured in degrees.

NOTE. If you make any changes to the Mobile Device Stand configuration, or if the eye tracker has been used for another purpose, you need to change the values to correspond to the current configuration in the X configuration tool and save the changes to the eye tracker. 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.
