Possibly a gesture control; they're becoming really cheap lately, search for "Rd-03E" on Aliexpress for example.

    They've been cheap forever, it's a competitive business advantage they deliberately pursue. Search for "the Nintendo Wii" for an example. =)

      My family loved the Wii to bits. In comparison our Switch barely gets used. If the Switch supported Wii games and controllers we'd still be using it all the time, but the Wii itself is way too slow and clunky to be tolerable these days.

        Dolphin (Wii Emulator) is very accurate, and can e.g. upscale graphics. And there’s a “DolphinBar” sensor-bar-looking transceiver to get perfect wiimote compatibility.

This is super interesting.

There are not many cases where one would opt for a radar based sensor over a stereo camera setup. Radar sensors have a notoriously bad azimuth/cross range resolution: It won't be able tell apart your fingers at a few meters distance, let alone recognize your face.

So i don't believe this will be integrated in gameplay features, it would fall short of the original eye-toy for PS2.

They might market this as a privacy preserving feature and enable some other functionality like human presence detection as mentioned in the article.

    Could it be designed for more outdoorsy type activity? For example, to recognize the surroundings, not the player? Distances to nearby walls and the ground?

    (I don't know enough about radars to say whether that would be feasible, or about games to say if there would be enough of a market for such.)

      Yes, sure those are possible applications especially when combined with a camera for some sensor fusion.

      Maybe Nintendo releases a switch accessory which lets kids play police and report speeding cars. Surely that would be fun.
