I don't really know where to put this exactly, but I guess this forum about fits the topic.
Today, I was looking through some stuff over on etsy and came accross something interessting: The Deepthroat Trainer by ResearchAndDesire.
According to the description it uses an optical distance sensor to track the position of one's head. And from what I found so far the WiFi-component isn't an option, but the only way to get it to work. I'm not sure how much I like that, but I guess in 2022 everything has to be connected to the Internet. There's minimally more information about what you can do with it on the website of the manufacturer: https://researchanddesire.com/how-to-use-your-trainer/.
Of course, the price tag is rather high. I haven't checked the exact shipping rates on the website, but for me, living in Western Europe, it ends up at around $200.
