The interval is now placed in the processing queue. Right-click on the selected interval or click the ellipsis (.) located directly over the timeline, and select Run assisted mapping.This is most often the part of the recording where the location or object shown on the Snapshot comes into view. If needed, you can zoom in on the timeline to make the interval selection easier. To select an interval, drag the yellow handles on either side of the red track slider to where you want the start and the end of the interval to be. Select the interval on the Timeline you want the gaze points to be to mapped automatically in.You can also select which Snapshot to map data onto from the list of Snapshots located below the replay Timeline. In the grid/list of Snapshot images, select the Snapshot onto which you want to map data.

How to map data onto a Snapshot or Screenshot using the assisted mapping algorithm: Then click the Snapshot to map the gaze point in a new location. To move a mapped point, right-click it and select Delete current manually mapped fixation point in the menu. Replay or manually step through the recording using the arrow keys once the mapping is completed and compare the mapping on the Snapshot with the gaze locations in the video to verify that data has been mapped correctly.As data points are mapped onto the Snapshot, the Snapshot timeline will indicate at which times data points have been mapped. Continue this process until all data has been mapped onto the active Snapshot.Click once in the corresponding location on the Snapshot image as precisely as possible. To map data onto the Snapshot, first, locate the gaze data point (the circle superimposed on the video) in the recorded video.While skimming through the recording replay, locate and pause the video at the start of the section that you want to map onto the selected Snapshot.At any time during the mapping of data, you can switch back and forth between different Snapshots without losing mapped data. On the Timeline, each Snapshot is represented by a thumbnail as well as a row on which it will be displayed for which parts of the recording data have been mapped. This eliminates the need to use arrow keys to step forward manually on the timeline. Enabling this switch will cause the paused replay to automatically jump to the next fixation/raw data point on the Timeline when a gaze point has been manually mapped. Enable or disable the Automatically step to next fixation toggle switch.In the Gaze Data section of the Tools panel, select the Snapshots tab.If not already enabled, enable mapping by clicking the Snapshots switch just below the video display area.How to map data onto a Snapshot or Screenshot manually:
The mapping can be done either entirely manually, or in an assisted way by using the assisted mapping function. These images are used for generating visualizations, such as heatmaps and gaze plots, and Areas Of Interest. Data from a recording can be mapped onto one or several images.

Tobii Pro Lab addresses this challenge by allowing the user to map gaze data onto still images (snapshots and screenshots) of the environments and target objects. Again, the data collected by the eye tracker is mapped to a coordinate system relative to scene camera video, not to the static objects or person of interest in front of the participant. The same scenario arises if you are performing a study using a remote eye tracker and a scene camera. For most statistical/numerical analysis to be meaningful, the collected eye tracking data needs to be mapped on to objects of interest and into a new coordinate system with its origin fixed in the environment around the participant. Wearable eye tracking devices such as Tobii Pro Glasses 2 produce eye gaze data mapped to a coordinate system relative to the wearable eye tracker and the recorded video, not to static objects of interest in the environment around the participant wearing the eye tracker.
