Using filters may encourage student use of video. Filters are virtual add-ons to your image on the video. So rather than having to own and physically put on a hat, as an example, you can choose a virtual hat and it gets placed on your head in your video. And the hat would move with your head if you lean to the left or right, forward, backward, or turning.

You may choose from many options, depending on the application: in Zoom, with the options built-in, there are not a lot of choices; in Google Meet, you need to have added a third-party application (such as Snap Camera, which I demonstrate here), which gives you many options.

Filters are purely for entertainment, although you may incorporate them as part of an activity that calls for different characters, as an example. The use of filters speaks strongly to emotional engagement, as students may care more if they can be entertained by the filters.

In Zoom: the following video demonstrates how this can be done in Zoom, which has a built-in filters feature.

In Google Meet: this video demonstrates how this can be done in Google Meet, which does not have a built-in filters feature.
