Understanding Area-Of-Interest (AOI) Statistics

This article describes the “Area of Interest” statistics in detail.

You may want to read more about how to access the aggregate statistical analysis tools.

Calculating statistics for areas of interest
Calculating statistics for areas of interest (AOIs). Here we have 2 AOIs (A1 and A2). A1 is selected and highlighted (orange).

Statistics update

The statistics shown in the table only update when you press the ‘Calculate’ button.

You can change the parameters at any time. Click ‘Save’ to permanently record the -current analysis configuration.

Selected Area of Interest

Click in the media image to create or select AOIs. The selected AOI is highlighted orange both in the statistics table and in the media (see image above).

AOI Names

Areas are currently autonumbered. We plan to enable renaming of the AOIs in future. The naming scheme is A1 … An. Area names are displayed both on the AOI rectangles and in the statistics table.

Average first view (s)

This metric is the mean time for each selected viewer to look at the AOI, from the time the media was first shown to them. Measured in seconds.

Total time, all views (s, %)

This is the mean (over all selected viewers) of the total time spent in the AOI by each selected viewer. The value is given as seconds and as a percentage of the time the media was visible to each viewer.

Average time per view (s)

This is the mean (over all selected viewers) of the total duration of the time spent in the AOI by each selected viewer. Given in seconds.

Viewed by X of Y (%)

This expresses the number of viewers that looked at the AOI, and the total number of selected viewers. Given as a count and as a percentage of selected viewers.

Clicked by (# clicks)

The number of viewers who clicked the AOI at all, and (the total number of clicks in the AOI summed over all viewers).

Avg 1st Click

The mean average time over all viewers before the first click. Viewers who didn’t click are excluded.

Distribution

The intent of the distribution is to provide a visual description of viewers’ flow between AOIs. The left side is the start time (when the selected media was first displayed to each selected viewer) and the right side is the end time. Note that some viewers may have seen the media for more or less time.

This is a plot of the distribution of viewing time samples for all selected viewers, measured in seconds since the time the media item was shown to each selected viewer. The x axis is seconds and the y axis is frequency (sample count). Hover over the columns for detailed numbers.

Individual viewer statistics

Not only can you generate the average statistics for each AOI automatically within the platform, but our statistics export tool allows you to download a more in-depth range of statistics for each individual viewer, meaning you can run complex analyses including t-tests and ANOVAs as well. For comparison testing and large quantitative studies, this is where EyesDecide becomes incredibly powerful.
