    Hitchhiker's Guide gesture controls get real

    In Hitchhiker's Guide To The Galaxy, touch controls for technology have given way to touchless controls, where you just "gesture vaguely and hope for the best". Now Google and Amazon are trying to make this dubious method a reality.

    https://techxplore.com/news/2021-07-amazon.html

    Amazon on June 22 asked the FCC, which regulates airwave uses, for permission to market a device that uses radar. The technology captures movement in three dimensions, enabling a user to control its features through simple gestures and movements, the company said in a filing.
    The FCC earlier granted similar permission to Google for radar to enable touchless control of Pixel smartphones, the agency said in its letter approving Amazon's request.
    And the kicker? Amazon is pitching this radar as a 3D sleep monitor. Amazon will watch. you. sleep. Nothing wrong with that, nossir!

    I already control my technology through simple gestures and movements.

    It seems to me this has been a staple of science fiction, at least in the movies, for a while. And I suspect it will work about as well as the touchscreens on my phone or computer, which get what I want done correctly about 80% of the time.

    I'm already amused by people walking by seemingly talking to themselves, it will be even more amusing to see them gesturing wildly.

    The makers seem to be picturing Tony Stark "swooshing" aside his cutting edge holograms. Instead they'll be giving people the same cool factor as someone swatting away flies.

    We’ve been able to clap to turn the lights on or off since I was a kid.
    The greatest journey of all time, for all to see
    Every mission makes our dreams reality
    And our destiny begins with you and me
    Through all space and time, the achievement of mankind
    As we sail the sea of discovery, on heroes’ wings we fly!

    We've been able to turn the lights on or off by making a simple poking or flicking movement with the index finger of one hand since I was a kid.

    Doesn't a Wii do that?

    Yes, but you have to touch something to do that. Now you can flick your finger from across the room!

    ...Wait, that doesn't sound right.

    I suspect that one of the problems with this technology, as with the Wii and similar, is getting it to pay attention to the right signals and understanding what your signals mean. With the voice systems, you don't want it to order two cases of cat food from Amazon when you are just yelling at your cat to get off the sofa. And then there are all the classic problems of Wii or Siri not understanding what you are saying when you do speak to them.

    I suspect there are similar challenges with gesture systems. If I yawn and stretch my arms, I don't want my computer to erase my files and magnify the image on the screen.

    I acquired a new gimbal for my phone not long ago and the associated app has features for control gestures. If I want get a photo of The Wife and I during our travels, for instance, I can set the gimbal down on its attached mini tripod and flash the camera the peace sign. This triggers the shutter after a short delay, so I can not be flashing the peace sign in all of our selfies.
