“We developed a deep neural network that maps the phase and amplitude of WiFi signals to UV coordinates within 24 human regions. The results of the study reveal that our model can estimate the dense pose of multiple subjects, with comparable performance to image-based approaches, by utilizing WiFi signals as the only input.”

Home automation nerds would also cream their pants if they could get their hands on this. Imagine you could use your existing wifi router to detect presence in your home. Say goodbye to shitty IR sensors that forget about your existence within 3 seconds, no more finicky radar modules that are either too sensitive or not nearly sensitive enough.

I literally just have my machine ping my phone every ten seconds. Surprisingly effective presence detection.

How would one go about setting this up? Because that sounds really cool for home automation.

There is this Home Assistant integration which I remember getting working. I haven't used Home Assistant in a while though, so I can't be a good resource if you need any help.
