> 2) Range hardcapped at ~1m due to how ultrasound works, you can't centralize detection. Their answer is to give everyone in the household a wearable receiver, which is eeeeeeeh idk, doesn't look consumer-friendly to me.
Sure yes if you could do this with an always-listening smartphone or smartwatch that would be workable, but even then it constrains it to an occupant-activity detector.
Fixing that would require in the best case prompting an app install when visitors arrive. And still it is deaf to any other changes such as a door closing in the wind.
All possible, but feels several technosocial cycles away. Interesting to think about anyway.
Variations might be better for underwater or surface impact detection, but for now, congrats to them on the reinvention the 1950s Zenith ultrasonic remote.
My grandfather used to love to show off how he could jingle his keys to turn on his TV.
Also, without regulating the ultrasonic frequency space, I imagine this would be prone to interference from other devices already employing ultrasoud, today, like Google Home.
