See the upper left corner of the Record screen, as shown below. Figure 25. The Record screen upper left corner When the camera is in zoom-in mode, the area outside the zoomed viewport will not be available and will not be recorded. Zoom and Calibration: I t is recommended to zoom the camera out before starting the workflow of a calibration with marker. If the camera is zoomed in when a calibration with marker is initiated, the camera will automatically be zoomed out. 7.5 Calibration Tobii Pro Glasses 3 supports two methods for calibration described below. It is possible to collect eye tracking data in the glasses without calibration, but this will make the eye tracking data be less accurate. For highest eye tracking accuracy, the eye tracker needs to be calibrated for each participant wearing the glasses. Calibration with a calibration target is the method that gives the best eye tracking data accuracy and requires that the participant looks at a known target such as the calibration target. See Cal- ibration with target. Tobii Pro Glasses 3 User Manual v 1.18...
Auto calibration c an be done without any specific target (e.g., when under time constraints). S ee Calibration without target. 7.5.1 What calibration does The human eye shows a natural individual variation in its shape and geometry. For example, the exact location of the fovea, the area responsible for the part of the visual field that we perceive in focus and full color, varies from individual to individual. Tobii Pro eye trackers use an individual calibration procedure to optimize their gaze estimation algorithms (i.e., the 3D eye model) and account for this variation. The end result of this optimization is a fully customized and more accur- ate gaze point calculation. 7.5.2 Calibration with target Tobii Pro Glasses 3 comes with preprinted calibration targets for this purpose. The marker should be positioned in front of the person at around 50-100 cm and held still before the calibration is per- formed. The diameters of the circles in the marker are 43 mm/23 mm/3 mm. If a marker with the wrong dimensions is used, the estimated distance to the marker will be wrong and the eye tracking error will increase. During the calibration process, the participant must wear the head unit and focus their gaze on the center of the calibration card. You can turn on and off the calibration sound using Settings in the controller applic- ation menu. The red circle (gaze overlay) shows what the participant is focusing their eyes on. Before cal- ibration the gaze overlay will not accurately show where the participant is focusing. The green circle (calibration target indicator / marker) shows what the calibration is tracking. 1. Hold the calibration card facing the participant at about arm’s length, 0.5 to 1 m (20” — 40”). Tobii Pro Glasses 3 User Manual v 1.18...
Page 49
Make sure that the calibration card is visible in the scene camera Record screen. The calibration card is not required to be in the center of the scene camera view. Hold the calibration card in the area of the view where you want the most accuracy. 2. Ask the participant to focus on the center of the calibration card. The green calibration marker should be stable and centered around the calibration card. Keep the calibration card completely still during the calibration process. 3. Select the Calibrate button. 4. When the calibration is complete, a "success" sound chimes and you will see an on-screen confirmation. 5. If the calibration was unsuccessful, you will hear an "error" sound and you will see an on- screen error message. To fix this, repeat steps 1 to 4. For more information, read Troubleshoot calibration. 6. Verify the calibration. Ask the participant to focus on a known object and check that the gaze indicator in the live view matches what the participant focuses on. You can re-use the calibration card if there is no obvious thing to focus on. Check that the gaze indicator in the live view matches what the participant is focusing on. Tobii Pro Glasses 3 User Manual v 1.18...
Avoid flickering light sources. Make sure there are no other objects visible in the scene view that look similar to the cal- ibration card. The green calibration marker should follow the calibration card and not jump around in the scene view. Too dark or too brightly lit environments can also cause trouble with the calibration. Try making the calibration in another room or area with different lighting conditions. The distance between the eye tracking cameras and the eye can affect the calibration and tracking quality. Try fitting the glasses with the alternative nose pads to change the dis- tance. 7.5.4 Calibration without target Auto calibration of Tobii Pro Glasses 3 (without a target) can be done as long as the glasses are worn, and does not require the participant to be focusing on anything in particular. It is preferable if the gaze is in the center region of the field of view, but that is where gaze most often is. When calibrating without a target, the accuracy will not be as good as when doing a calibration with a target, but the workflow is easier and it can be done even in low light conditions where the low contrast of the target can make it hard to detect during calibration. 7.6 Start the recording After Calibration, s elect Record at the bottom of the window to start the recording. A timer dis- plays to indicate that the recording has started. Tobii Pro Glasses 3 User Manual v 1.18...
Every new recording should start with a calibration for best results. Read more about Calibration. 7.7 Create events while recording During recording, you can create a time-stamped event by selecting one of the New event or Event template icons on the bottom right of the recording window.

Appendix C Sync Port The recording unit is equipped with a sync port capable of transmitting and receiving a sync signal to and from external devices. The sync port is a standard 3.5 mm jack in which the tip is used for receiving a sync signal, the middle ring is used for transmitting the sync signal, and the sleeve is the ground. C1 Sync-out Sync-out is emitted from the recording unit using a standard TTL 3.3 V signal, described as a high signal (1) one, or a low signal 0 (zero). Implementation The sync signal, which is 10 000 ms long, starts when the recording starts, and is initiated by a start sequence in the following format: One 500 ms long high pulse, (3.3 V), followed by a 500 ms long zero pulse (0 V), repeated three (3) times. During the recording the sync pulse is emitted once every ten seconds with a duration of 1000 ms, followed by a 9000 ms long zero pulse, and so on. When the recording is terminated, the sync pulse stops immediately. No stop sequence is transmitted. C2 Sync-in Sync-in is triggered by the recording unit using a standard TTL 3.3 V signal, described as a high signal 1 (one), or a low signal 0 (zero). Tobii Pro Glasses 3 User Manual v 1.18...
