Active Session View
The Active Session View provides an overview of recorded session data while the session is playing. This is primarily to ensure all data is being recorded as expected. This is a Widget interface that appears over the VR Spectator View on the computer's display and is not visible in the HMD.
This requires Unreal 4.21 or later.
Simply add the ActiveSessionView actor to the level. It can be found in the "CognitiveVR C++ Classes/CognitiveVR/Public/" directory.

If eye tracking is supported, the participant's current gaze will be drawn as a red circle. Fixations will be drawn as yellow circles on the canvas. These represents the world-space they occured and will update as the HMD moves.
These points do not account for asymmetrical HMD projections and will not display on the canvas with perfect accuracy. You should use the tools on the Dashboard to analyze fixations.
