Dynamic Objects

This list shows Dynamic Objects that have been gaze at, or fixated on if the project supports eye tracking. By default, it will show the newest fixated object at the top of the list. You can click Sequence, the total Duration (in milliseconds) or the total number of Visits to sort by these values. These sorting options can also be inverted by clicking the title again.

Fullscreen View

Fullscreen View offers minimal details to see what the Participant is viewing in the scene. This copies the image from the HMD to render fixations and the current gaze, so may be slightly misaligned due to different HMD projections.
