Quasistatic Cavity Resonance for Ubiquitous Wireless Power Transfer
Why Hacker News recommends it
HN cites it as an example of early research into room-scale wireless power transfer.
What it is
Disney Research's demo of quasistatic cavity resonance, which uses a purpose-built room or cabinet to generate magnetic fields that deliver kilowatts of power wirelessly to mobile receivers inside.

That is doable right now. I am only sort of being glib here. I just want to outline what's involved in what people think is a simple task in a spatial system. TLDR: As of right now, your wildest dreams are pretty possible. In the next 2 years, how we compute is going to get strange. Nothing is nearly as simple in an XR environment as a traditional computing one and currently most people don't really want what they'd ask for. Building a simple (useful) XR app makes launching a web product look like assembling a lego set vs. landing on the moon. --------- Imagenet[0] works just fine for the object identification. You would probably want to use RGBd sensors like the kinect[1] or Intel Realsense

I mean, the issue with cameras on everyone is that they all require small batteries, meaning always recording with them isn't really practical. There is already early-stage research into long-range wireless charging [this video] so maybe 15+ years in the future it would be practical to have always-recording devices.
