Introduction
The Tobii Eye Trackers and the Tobii Studio software can be configured in many different ways. Also, the Tobii Studio software incorporates much more than just recording of eye tracking data, including various video and audio streams and integration with other software and hardware.
Altogether, this offers a highly flexible system, which can be configured to optimally fit the needs of different testing purposes.
This document describes recommended system configurations when using Tobii Eye Tracker hardware and Tobii Studio software, as well as current recommendations for components that form part of these systems/solutions.
Version information
As performance and product availability of many of these components change and evolve rapidly, the contents of this document are subject to constant and rapid change. Therefore, always make sure that you have the most current version available when deciding for a system configuration. The latest version of this document can always be downloaded from the Tobii website.
This is version 1.2.0 of the System Recommendation document, which is current per 2008-03-25.

Recommended System Configurations
The following chapters describe a number of recommended system configurations which are suitable for different situations. Your particular needs may of course differ from these standard configurations, but they should give valuable insights in any event.
For specific information about custom configurations, or detail questions on the system configurations, please contact your Tobii sales representative, or Tobii technical support at [email protected].
Single Screen Setup
This basic setup is the most simple setup when using on screen stimuli, such as images, movies, web or screen for advertising & usability testing, psychology research, reading research etc
The pictures below illustrate the single screen setup with the two eye tracker connection alternatives using a USB-LAN adapter and a network connection.
To get a portable lab replace the computer in the setup drawing with a laptop or shuttle computer.

Local Live Viewer
The below setup is used when the test is to be supervised from a screen next to the eye tracker setup. This test setup is suitable when using on screen stimuli, such as images, movies, web or screen for advertising & usability testing, psychology research, reading research etc.
In a lot of studies it is important to see the participant’s reactions and record the conversation between test leader and test participant as well as using think-aloud. The setup below includes the user camera and user sound. Both the user camera and the user audio are optional.
An alternative to using the adapter in the setup drawing is to connect the eye tracker to a local network, see more under the single screen setup option.

Remote Live Viewer
This setup is used when the test should be supervised and/or controlled from one or more remote stations. It can be a computer in the next room where a supervisor is sitting and a computer connected to a white screen for remote viewing for customers etc. This test setup is suitable when using on screen stimuli, such as images, movies, web or screen for advertising & usability testing, psychology research, reading research etc.
In a lot of studies it is important to see the participant’s reactions and record the conversation between test leader and test participant as well as using think-aloud. Both the user camera and the user audio are optional.

Tobii X120 Eye Tracker Setups
Monitor or projection screen
The Tobii X120 Eye Tracker allows for eye tracking using multiple stimuli types such as TV, monitor and projection screen. In the drawing a monitor is shown, but it can be replaced by a TV or projection screen as long as the input comes from the computer. In a lot of studies it is important to see the participant’s reactions and record the conversation between test leader and test participant as well as using think-aloud. The setups below do not include the user camera and user sound; see more in the Tobii T60 Eye Tracker live viewer setup. To use the user camera and sound option or the Live Viewer in Tobii Studio a Professional or Enterprise edition of the software is required. Both the user camera and the user audio are optional.

Physical objects and scene camera setup
The scene camera setup is suitable when using a Tobii X120 Eye Tracker for recording and analysis of eye tracking data, when the stimulus is a physical object, for instance an object on a table or a PDA.
Please refer to the “Tobii X120 Eye Tracker Quick Guide” for precise configuring of the geometry in a Tobii X120 Eye Tracker setup.
* The eye tracker can also be connected directly to the network instead of using the USB Adapter. See the single screen setup for more information.

Advanced Setups
External video recording – RGB/VGA source
This setup is suitable when using a Tobii Eye Tracking system for analysis of eye tracking data when the stimulus is presented from a separate computer or some other type of RGB or VGA source. This could for instance be when doing usability testing on a computer game, or even when stimulus is presented on a computer running a different operating system such as OSX, Linux or Solaris.
Please note that if the external application runs under Windows operating system, and does not make use of 3D graphics acceleration, it may be more suitable and less complex to instead run this on the same computer as Tobii Studio, and use the Screen Recording option in Tobii Studio.
For this setup, the image from the Tobii Studio computer has to displayed on the Tobii T60 Eye Tracker display during calibration (to display the calibration points), whereas the external stimulus computer should be shown on the Tobii Eye Tracker display during the actual test. Therefore, both computers have to be connected to the Tobii T60 Eye Tracker. To switch between the inputs press the source button on the Tobii T60 Eye Tracker front.
The video shown on the eye tracker display also has to be sent to Tobii Studio to record the video stream and synchronize it with the gaze data.
If the stimulus is presented from an analogue video source, for instance a VCR or an analogue video camera, it is possible to use a similar setup with slightly modified components.

* The eye tracker can also be connected directly to the network instead of using the USB Adapter. See the single screen setup for more information.
There are two monitor ports on the Tobii T60 Eye Tracker, one VGA and one DVI connector. If all cables used in the setup are VGA cables a VGA-DVI adapter can be used.
To show the image from the stimulus computer on a separate supervisor screen use a splitter between the stimulus computer and the stimulus presentation screen. A splitter can also be used to split the signal to the RGB capture card and the Tobii T60 Eye Tracker monitor if a laptop or other computer with a single head graphics card is used.

Tobii / E-Prime integration setup
E-Prime is a leading software package for designing and conducting psychological experiments available from Psychology Software Tools. There is an extensive package called “E-Prime extensions for Tobii” for integrating the E-Prime software with the Tobii eye tracking system. This enables you to use E-Prime and E-Basic to design sophisticated stimulus, for instance to create gaze-contingent, conditional and counter-balanced experiments.
The Tobii extensions for E-Prime offer a set of native E-Prime objects tailored for the Tobii eye tracking system. These offer functions on two different levels:
TET level In this mode, E-Prime controls the Tobii Eye Tracker Server directly, without the need for using Tobii Studio at all. E-Prime performs calibrations, collects gaze data and saves this to file.
Tobii Studio level In this mode, E-Prime remote controls Tobii Studio. Timing is synchronized between E-Prime and Tobii Studio, data is collected by both E-Prime and/or Tobii Studio, and Tobii Studio can also be used for data visualization and analysis.
It is suitable to place the E-Prime software on a separate computer, and have this communicate with the Tobii Eye Tracker Server and Tobii Studio software over TCP/IP. An RGB capture card may be used to capture a video of the stimulus presented by E-Prime into Tobii Studio for visualizations and post-recording analysis.
For more information about E-Prime, please visit www.pstnet.com.
* The eye tracker can also be connected directly to the network instead of using the USB Adapter. See the single screen setup for more information.
