if you hate phage - i am going to make your head explode :
Cicret Bracelet is a fake the concept cannot be realised [ as claimed - resolution // image size and profile ] with any availiable [ or imminent ]
technology
The new and evolved tech inventions over the next decade will be around computing, big data and AI. This will spawn "driverless" everything, and all
that. New materials, like graphene and things like battery technology will also be exploited.
What you use on your wrist will be just a gimmick.
Everything exists out there somewhere? Yeah sorry to break it to you OP but we are not living in the Hitch Hikers guide universe. We cannot just use
an infinite improbability drive to create things from randomness.
If you want to claim everything that people can imagine exists... then most of the stuff people imagine I hope is nowhere around the local
universe.
If we want to play devils advocate then, we already made FTL travel because there was a movie about it... many movies in fact. Darth Vader exists out
there somewhere right?
The reason the bracelet will not work at least in day time is that there are no high power LED's that will fit in that small of a space. Then there is
battery power and life, if you have a battery powerful enough it will not last long ( 1-3minutes).
The phone that tracks your eyes to make a 3D image on the screen is possible but only while looking at the screen, not the edge of the screen.
