A glimpse of the future
It's not often that you see a glimpse of the future that changes your perspective so radically. I recall first seeing the Windows GUI (user interface), which was demonstrated in the early 1980's on an Apple Lisa (the forerunner of the Apple Mac). It took a long time for the implications to sink in, and for die-hard programmers like me to give up the command line.
The video below from MIT research labs shows some inciteful research of the possibilities of matching a built-in projector and using your hands as an input device whilst out and about. It reminds of the film Minority Report with Tom Cruise.
It's entitled the Sixth Sense Tech of the Future.
Futuristic predictions like this do have a habit of not becoming true in their entirity, so healthy skepticism is order of the day. But some of these concepts may well shape the way we interact with devices and our environment in the years to come.
Well worth a few minutes of your time to review – you can skip to about 2:30 where the actual demo starts...
