Some kind of input device
In this unedifying diagram of event dispatching, what does the graphic in the bottom left represent? It will be a system or device producing input of some kind. It looks like an egg carton filled with bacteria. Card Zero (talk) 06:48, 7 May 2022 (UTC)


 * It's likely natural events, multiple organisms moving independently? WhoAteMyButter  ( 📨talk │ 📝contribs ) 07:37, 7 May 2022 (UTC)
 * None of the other input sources represent sensors, so indeed this Petri sixpack plausibly stands in for sensors (which could be sensing natural processes). It does not immediately evoke the association, but I'm not aware of any iconic representation that clearly signals "sensor". --Lambiam 09:40, 7 May 2022 (UTC)
 * Kivy seems to be open source software, and so are the docs. That particularly image seems to be here [//github.com/kivy/kivy/tree/master/doc/sources/guide/images]. It's possible exploring the history will give some clue what the image is about, or not. Nil Einne (talk) 12:39, 9 May 2022 (UTC)
 * Some examples of fiducial markers that can be placed on objects or in video for automated recognition and tracking, from a library called reacTIVision: project page, publication. --Amble (talk) 20:30, 9 May 2022 (UTC)
 * Oh! That's the one. Maybe Kivy was involved in the Reactable. It's all very circa 2010. I see a bit more interest in tangible user interfaces was stirring in 2017, but I imagine projects that involve a lot of people gathering at a table to touch shared objects have been discouraged by the pandemic.
