Example still from a video of operator 1 showing overview gaze. Note. The saccade-fixation pattern shows that the operator switched between different lock chambers, looking at streams from the middle towards the upper row (top-middle screen). This can be classified as 'overview gaze' because experts related these fixation patterns to creating an overview of one or more lock chambers by switching between different overview camera streams. For example, expert 15 mentioned: 'But also forming the entire overview image. Yes, you saw that come back a few times. So really visually inspecting those three lock chambers'.

This paper reports a qualitative exploration of gaze strategies during closed-circuit television (CCTV) tasks in remote nautical object control of a lock. Previous research has not examined gaze strategies in scenarios where systems, such as nautical objects, are operated remotely using CCTV. As contextual factors matter in nautical object control,...

... other gaze data settings, opacity was set to 50%, size to 30%, fading duration to 2 seconds, and maximal size to 60%. Examples of video stills are presented in Figure 3, Figure 4, and Figure 5. After creating the videos, anonymisation by face detection was applied using Python 'deface' on six videos. ...
Context 2
... Overview gaze. Overview gaze concerns situations where operators' gaze focused on creating a helicopter view of the nautical object and keeping in mind the overall process of nautical object operations (see Figure 5 for an example). In this case, operators did a specific task with the overall process in mind, and as a result did not only focus on the lock gate closing procedure. ...
Context 3
... example stills from a video of operator 1 show situations that all experts that looked at these videos consistently described as showing a specific gaze strategy, namely, anticipating gaze (Figure 3), verifying gaze (Figure 4), and overview gaze ( Figure 5). ...
