’Smart’ bracelet that projects screen onto arm

I call dodgy if even doable? Donations only? No crowdfunding? So many questions regarding the tech/physics wouldn’t know where to start….

Wildly over-optimistic at least. That project can be shot down on the brightness of the LED, the compactness of the projection equipment and the battery size/lifetime.

It’s a bit like this ring project. A nice idea but technologically difficult to make in the budget they will have.

It was kicked off the crowdfunding sites as they couldn’t prove it was possible. No working prototypes, no viable plans for getting to one.

reminds me of these a bit.

if they can get the resolution and brightness, the touch detection is apparently already possible?

That arm screen thing is pie in the sky. The ring, hmmm, vaguely possible, but will probably end up transferring £2k to your MiL if you forget you’re wearing it and flog the dolphin.

Verdict: impossibruv/10

EDIT: the LASER keyboard works because it’s actually possible to keep a monochromatic beam sharp, and it also works well on flat surfaces. Not arms, and especially not on any bugger’s arm of a different shape to the one it was designed on.

[This is all coming from a guy who “designed”* a Mac mini style small form factor PC with a flip up arm for Laser Keyboard and Screen projection in the wall/desk in 2009]

*Pre-university – it was more of an essay with pictures.

The last comment “The expression is shut up and take my money” – well I’m sure they’d be happy to do that. Far too many people asking where they can buy one, not enough doubt over whether it’s actually possible.

Is that where people want gadgetry to go then? Stroking/tickling/rubbing parts of the body to control phones? Fab.

Strangely hairless models there. I think in the future we will all have to be fully waxed every two weeks or our gadgets won’t work properly.

Alternatively, I know a device that can project your arm onto a screen.

lol @ gofasterstripes. True – the times I’ve come close to mistakenly delivering MoL an Amazon package – and that’s without encumbrace of dolphins, rubbing arms, waving rings or anything other than a conventional mouse.

Reminds me of this scam I saw on Indiegogo today:
https://www.indiegogo.com/projects/bleen-3d-without-glasses

It gets bonus points for using easily found stock photos, and the mockups showing it somehow projecting dark colours.

Edit: On second watch, I especially like that the arm in the bath on the Cicret video is out of focus, and the screen is in focus.
