When we have near-human level deep learning models for things humans can do, what does this level of performance look like when applied to things we can’t do at all? This is a nice example of this.

IEEE 802.11bf aims to standardize through-wall motion sensing for Wi-Fi 7 in 2024, https://www.originwirelessai.com/insights/what-is-the-802-11... & https://www.originwirelessai.com/insights/origins-next-chapt.... It can be done today with custom firmware on low-cost WiFi devices. Over the past decade, hundreds of Wi-Fi sensing papers have been published, for different categories of motion.

Take a look at Figure 10, mind blowing.

This tech will make it into every device with an RF receiver. Your TV, phone, router, computer, tablet, fridge, lightbulb will know your pulse and waste size at all locations in your house.

From the abstract: "This paves the way for low-cost, broadly accessible, and privacy-preserving algorithms for human sensing."

How much do we have to wait for the follow up paper: "Human identification through wifi signals" and then the patent for "Wifi as an identity tracking source for advertisement in public spaces"

Technology advances make me sad those days...

Just because this surveillance tech avoids photons with energies accessible to human photoreceptors doesn’t mean it preserves privacy.
