Individual Recordings / Replays

To replay individual eye/gaze and mouse recordings, first open the study from your homepage, the studies/index page. Then select the “Recordings” tab. You will see a view much like the one below.

You can only view replays for studies that have been launched and have received successful viewings. If these conditions are not true, you won’t see the “Recordings” tab.

Recordings Table View

The recordings table allows you to view, sort, filter and tag individual results. It’s a great way to analyse and group participant behaviour. Successful views also have a green ‘Play’ button on the right side.  Click these buttons to replay individual views.

We packed in as much information as we could about each view. In addition to the basics such as viewer, date/time and ID, you’ll want to pay particular attention to:

  • Result: By default, successful views are shown if any are present. However, you can also show all viewing sessions.
  • Score: We only deduct viewing credits for views with an accuracy score of more than 70% (these views have a tick). Often other views have good results too, it’s just we can’t automatically prove it. If you manually replay some of the lower scoring or un-scored results (n/a), you can decide whether you want to use them. A score of “n/a” means the viewer looked away from the computer before the accuracy test was complete. The viewing session may be perfectly good.
  • Media: Since we allow complex workflows, each viewer may have seen a different sequence of media items. These are presented so you can group and filter results.
  • Tags: This is essential to getting the most out of EyesDecide. Use tags to group results for later aggregate analysis.
  • Viewer: If you asked an identifying question or participants were recruited from a third-party survey, this information about the viewer is presented here, including ID on the 3rd party system (if provided).

Survey results

You can also access survey results from the button at the top of this page.

Individual Replay Interface

When you click one of the green ‘Play’ buttons the individual replay interface will open. It replays fullscreen to give you the best impression of the viewer’s experience. Note that viewers may have had a different screen size to you.

The media is centered if it is smaller than the screen dimensions. Otherwise, scroll is enabled. By default, the scroll action will repeat what the user experienced. However, you can turn this off if you prefer.

There is a floating black toolbar at the top-left of the screen. You can move this around with the icon in the top-left corner. It also has a ‘v’ button to expand and see the full toolkit (explained below).

You can play/pause replay and adjust the viewed time point using the default controls visible when the toolkit is collapsed.

Gaze and Mouse tracks

The replay interface shows a RED track (eye/gaze) and a BLUE track (mouse). You’ll notice that often, viewers look around without moving the mouse at all.

If you see the mouse move in a straight line, as shown below, the mouse cursor has shifted due to a user scroll action.

Individual replays also show a “heatmap” effect. This is not an aggregate heatmap. Instead, this is a history of the current view being replayed on the current media item. It’s stickier than the gaze track, which only shows the last 1-2 seconds. So, at any given point in the individual replay, the heatmap shows what the viewer has seen so far.

The “heat” colouring is a measure of how long and how often the viewer has looked at any given point on screen. You can change the heatmap effect with the expanded toolkit, described below.

Replay Toolkit

Clicking the ‘v’ button in the toolbar expands the set of tools. These are described on another page. Notably, you can tag views from this interface and change the visual effects.

Replay All Views Simultaneously

If your study has only ONE media item, you will have the option to select “All views” in the expanded replay toolkit. You will then see all individual tracks at the same time.

This feature is not available if your study has more than one media item, because we can’t render the background image if different viewers see different media at the same time. The results wouldn’t make any sense.

How to Export replays as videos

We often get asked how to export individual replays as a video file. We wrote an article about that.
