Changing a variable font's grade depending on ambient light

I'm doing a project on Variable Fonts and their benefits and am looking to use some practical examples.



During my research I found a video of someone putting their hand over the ambient light sensor on their laptop which then adjusted the grade of a variable font for legibility reasons. You can see the video here - http://tom.lokhorst.eu/type/video



The person in the video stated in a tweet "this is a quick hack using a native macOS app to observe the display brightness". This was something I wanted to recreate without the app but by using javascript to access the ambient light sensor if the user's device had it.
I thought this would be a relatively simple thing to recreate however I've spent all day trying but haven't been able to figure it out which is why I'm here asking for your guys' help!!



If the app is something that is necessary does anyone know which app he is using?



Many thanks,
Adam

  • This isn't really what Stackoverflow is for. Take the tour to get a better idea what it is for, which doesn't take up a lot of time, but makes a lot of things more obvious. In this particular case: you found the video, you know who made it, so instead of asking us what they used, ask them what they used. They're the first person you should ask this
