Getting Started: Getting Started with Data Viewer
SR Research Data Viewer is a sophisticated and intuitive software package for viewing, filtering, and processing gaze data recorded with EyeLink eye trackers. It runs under Windows, Mac OS X, and Linux.

I. Installation:

You can download the appropriate version of Data Viewer for your OS from the link below:

II. Software Licensing Installation:

You need to use either a physical USB license key or a software license (or be running on a computer that is on a network with a networked license key on it) whenever you are using Data Viewer.

Windows: After Data Viewer has been installed, you can go to Start -> Programs -> SR Research -> Install Hasp Driver to install the Hasp driver

Mac OS X: The Hasp runtime environment installer (the Hasp driver) is packaged with the Data Viewer DMG file. After launching the Data Viewer DMG, please find the driver in HASP -> Sentinel Runtime.dmg. You can launch the Sentinel Runtime.dmg to install Sentinel Runtime Environment and install the driver.

III. Learning Data Viewer:

For a general introduction to Data Viewer please watch the following Data Viewer Video Tutorial Series: Another great way to learn Data Viewer is to work through the Data Viewer User Manual (Help -> Contents).

IV. Data Viewer Example Analysis Sessions:

There are Viewing Sessions that you can use for practice in the Webinars listed below:

V. Data Viewer Frequently Asked Questions:

The answers to many common Data Viewer issues can be found in the following section of our FAQs.

VI. Data Viewer Life Cycle - from importing EDFs to outputting reports:

The typical steps in analyzing EyeLink data using Data Viewer are as follows:
  1. Open Data Viewer and import all the EDF files from your experiment using File -> Import Data -> Multiple EyeLink Data Files. Save the viewing session somewhere sensible (for example in the results subfolder of the deployed project if you used Experiment Builder to program the task).
  2. Set an Interest Period to define the temporal window of interest for any subsequent reports and analysis (for example from when stimuli were displayed until participants responded). You can read more about how to set Interest Periods here.
  3. Check through data, using temporal graph / spatial overlay or animation playback views as appropriate. Adjustments to fixations / saccades can be made in temporal graph and spatial overlay views. If necessary, Interest Areas can be created in spatial overlay view, saved as templates and applied to other trials.
  4. It can be helpful to use Trial Grouping (Edit -> Trial Grouping) to group data by key variables, and then create heatmaps / use aggregate data mode to explore gaze behaviour / guide subsequent analysis
  5. Output reports at the Trial, Interest Area, Fixation, Saccade or Sample Level. You can also output reports containing messages, or a Time Series (binning) report for Visual World type tasks or when dynamic stimuli were used. If you have used Trial Grouping, then you can also run aggregated event and interest area reports.
