Holy crap. If they did not have videos of all these technologies, I would not believe them. These prototypes work. They just work. It's only a matter of scaling up the detail and packaging it right for consumers. The future is here.
I really like the scratchable input idea, but their gestures seem overly complex for realistic use. I think that double tapping on my desk to answer or hangup on a speaker phone call would be a nice touch to any smart phone. You could probably implement it with the microphones already existing on most handsets.
Any idea how hard the ultrasound radiation pressure (used in the tactile holograms) would be to make?<p>I guess you just need transducers, and some software to time them correctly? That's unbelievable to me.<p>They say they can't get very powerful though or stray sound would damage your hearing. I wonder if there's any way around that? i.e., different frequencies?
