How does it work for tvs in practice? Skimming the article, it seems a large practice was to use the sounds as confirmation of user location (were they at an event). What ultrasonic source is my tv likely to pick up?
- akimbostrawman 2y agoAds can also have ultrasonic signature for example if you listen to an ad on your phone nearby. Ofc it could also just listen to itself
- wkat4242 2y agoI noticed Microsoft teams seems to do something like this. If I walk into a meeting room it tells me the same meeting is on speaker and do I want to mute my laptop.
- wlonkly 2y agoZoom also uses ultrasonic location to identify meeting rooms, but that's when you're already in the Zoom app which is expected to use your microphone or speaker.
