Conducting a Pilot Study
Before conducting an actual study, always follow the steps below to perform a complete pilot study:
1. Complete a recording including calibration. During this recording make sure to test any potential angle of
approach a participant might take to verify how your setup works under different conditions.
2. Analyze and replay the data in Tobii Studio. Confirm that the data is correct and there is no unexpected data
loss and your setup is working as expected and meets your established requirements. Use the Glasses Data
Viewer feature (right click on any imported recording in the Replay tab to access) To analyze a recording in
more detail and find how the IR Markers are picked up by the glasses for your specific study setup.
3. Confirm that the expected data and results can actually be obtained during analysis by doing a full analysis of
the pilot recording.
4. If necessary, make adjustments to your setup or test procedure and confirm with another pilot recording if
uncovered issues are actually solved.
5. Continue with your study once a pilot study has been completed successfully and the results conform to your
established requirements.
6 Pilot Study
Conducting a pilot study will help you to detect potential issues with your test design or test environment and will
help you resolve and avoid them before the actual study is conducted. Tobii Studio may be limited in the type of
analysis you can do, depending on how the study was designed and conducted. Be aware of any potential limitations
by completing a full pilot study including analysis. Skipping these steps may result in erroneous or incomplete data or
analysis options after the study may be limited.
