This step is important for the student's eye movement recording to be of good quality and reliable. ### Process for ensuring an approved calibration 1. Check that both the equipment and the student are in the correct position. 2. Give the student their instructions following the script provided within the Test Application. 3. Click **'Start Calibration'.** 4. The red and green circles are the student’s eyes moving across the application interface. Make sure the student focuses on the moving circle, especially when it stops. Watch the student’s eye movement and give guidance if the student does not follow the moving circle around the screen. Also, ensure the student stays in the correct position *(green positioning tool to the left of the application)* and watch that they do not move their head when following the circle. 5. Calibration ends automatically, and you will be presented with the results which appear as an image on your screen. 6. If for some reason you want to stop an ongoing calibration, click on 'Stop Calibration'. 7. If calibration was unsuccessful, give the student the instruction again and click on 'Start Calibration'. Calibration starts immediately. 8. When calibration is complete and of approved quality, click **'Next'**. #### Examples of different quality calibration results: **Optimal** Two lines inside all circles ![](https://info.lexplore.com/hs-fs/hubfs/Knowledge%20Base%20Import/image-png-Aug-18-2020-10-12-00-19-AM.png?width=349&height=278&name=image-png-Aug-18-2020-10-12-00-19-AM.png)   **Intermediate** Lines within 4 out of the 5 circles ![](https://info.lexplore.com/hs-fs/hubfs/Knowledge%20Base%20Import/image-png-Aug-18-2020-10-12-52-87-AM.png?width=348&height=310&name=image-png-Aug-18-2020-10-12-52-87-AM.png)   **Poor Calibration** Lines are too long outside of the circles. Only accept this result after trying to calibrate a maximum of three times. Add a comment at the end of the test. ![](https://info.lexplore.com/hs-fs/hubfs/Knowledge%20Base%20Import/image-png-Aug-18-2020-10-18-26-64-AM.png?width=365&height=307&name=image-png-Aug-18-2020-10-18-26-64-AM.png)   **Incomplete Calibration** The two circles at the bottom are not visible as they lack lines. This means the pupil’s eyes were not detected at these points. Check positioning! Only accept this result after trying to calibrate a maximum of three times. Add a comment at the end of the test. ![](https://info.lexplore.com/hs-fs/hubfs/Knowledge%20Base%20Import/image-png-Aug-18-2020-10-19-42-11-AM.png?width=377&height=320&name=image-png-Aug-18-2020-10-19-42-11-AM.png) If you can’t achieve a good calibration of the eye tracker with a student, try a maximum of three times and then continue with the rest of the test. Ensure you add a comment at the end of the test to advise of the problematic or incomplete calibration. --- 🛎️Here at Lexplore, we love to help our users with their questions and provide self-help guides for quicker service.
