How to use the AOI Editor

  • Created
  • Updated

With our AOI (Area of interest) editor, you can draw AOIs at any time: after designing your experiment, while in the fielding, or afterward, when you receive your results.

You can add AOIs to any of your media stimuli: videos or images.

When you are in the AOI editor, there are several options on the left panel or sidebar for you to add and edit your AOIs.

 

Select media

In the first section, you can easily choose which type of media to which you wish to add Areas of Interest (AOIs) to — whether it’s an image or a video. Additionally, you can zoom in on the selected media from this section.

Add and edit AOIs

Here you can select different tools for adding and editing AOIs on your chosen media.

Tools to add AOIs:

Rectangle

Draw AOIs with rectangle shape on your media. Simply click and drag the mouse to start to draw an AOI on your media.

Polygon

Select the polygon tool to make an irregular form by clicking and adding points to the shape, just make sure the last point and the first point meet in the same location. 

Import:

Importing a new representation is used on more advanced pieces of media where you need to change the representation of the entire media.

Drag shape
With this tool, you can select and drag any AOI and move it around on your media stimuli.

Edit point
This tool allows you to edit singular points on your AOIs. You can increase the size of your rectangular AOIs, or modify the vector points of your polygons.

Snap shapes
Select this tool if you want your AOIs to snap against each other while drawing them.

Areas of Interest (AOIs)

Your AOIs will be listed in the AOI section as you add them to your media.
 

More options
You can activate more options by clicking on the “…” of the AOI you want to edit.

Make AOIs invisible, edit, duplicate, or delete them easily from here.

A timeline with options will appear whenever you choose a video stimuli in the AOI editor.

Multiple tracks

The AOI timeline supports more than just a single track, enabling you to display many AOIs simultaneously. This provides a much better AOI overview and makes it easier to edit them directly on the timeline: Drag AOIs and shorten or widen the length of the AOIs on the timeline.

Playback functions

 
Audio control: Activate or deactivate the audio of your videos; if the audio is activated you can adjust the volume of the video you want to play.
Playback speed: Modify the playback speed to suit your editing preferences.

Seeking options: Easily navigate by jumping forward or backward on your videos in 5-second increments.
 
TIP: You can move to a particular moment in time by clicking directly on the video frames that appear in the timeline.
Jump to beginning/end: Quickly jump to the video’s start or endpoints.
Frame-by-Frame Navigation: Manually advance or rewind one frame at a time.

Play/Pause: Play or pause your video by clicking on any of those options.
