- nazgulnarsil 17y ago...tactile holograms? GIVE ME MY HOLODECK. Please, please be in my lifetime.
- w-ll 17y agoHow old are you? I only wish I could have gone to siggraph this year
- utku_karatas2 17y agoI wouldn't hold my breath. Touch screens were invented in, what, 70s? And it took somewhat 30+ years for it to be widely used by the average person.
- nazgulnarsil 17y agoassuming that we'll see change at the previous growth rate is silly if we get molecular engineering.
- ljlolel 17y agoHoly 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.
- snprbob86 17y agoI 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.
- liuliu 17y agoMany two or three microphones can do better? Distinguishing position or something. That can be very useful.
- snprbob86 17y agoIf you knew the position of the sensors, you could probably calculate a position from audio/vibration delays. You could make a kit for converting a normal whiteboard into a recording surface. Simply place sensors on the board corners and tell the software about their placement and the dimensions of your board. You need three sensors to do a proper triangulation, but you only need two if you know the sensors are in corners. With only two corner sensors, one of the two possible locations would be off the board, so you could throw that point out. If you can reliably sense whiteboard marker and eraser sounds, you could reliably "save" the whiteboard state.
- nvoorhies 17y agoWouldn't the delay between 2 sensors only give 1 delay, and thus one dimension? I don't follow how placing them on the corners makes this work.
- snprbob86 17y agoD'oh! Sorry, you are correct. I was thinking you'd get two distances to point of contact, but you actually get relative distance of the point of contact with respect to the sensors. You are correct, you would need three sensors.
- alex_c 17y agoThis... is magic. Plain and simple. Desktop fabricators, now "touchable" holograms. What a great time to be alive :)
- sp332 17y agoAny technology distinguishable from magic is insufficiently advanced. :) --Gehm's Corollary to Clarke's Third Law (smiley added)
- tocomment 17y agoAny idea how hard the ultrasound radiation pressure (used in the tactile holograms) would be to make? I guess you just need transducers, and some software to time them correctly? That's unbelievable to me. 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?
