Comments on Touchable Holography Display
Video presentation shows that it is possible to touch a three-dimensional holographic object. (Read
the complete story)
| "My first thought was :O. But upon later thought, It's really neat from the ultrasound standpoint, but from the perspective of 3D imaging, it might as well be a 2D image. It's a neat idea but until they can get the object to project a touch sensation from any direction as well as from inside a closed hand, it is really just smoke and mirrors."

| "It's a step in the right direction. This would never have been considered outside of SciFi just five years ago." (Joey1058 8/6/2009 6:20:30 PM) |
| "I'm still fairly amazed. For a prototype, it's a very effective demonstration." (Bill Christensen 8/6/2009 6:56:33 PM) |
| "Well if this application can't be adjusted to 3D, what use is it? It will have to be trashed at some point when a technology that can be brought to 3D can be used. If the technology isn't scalable to the next step, it isn't a step in the right direction, just a step. I could put little motors in my mouse that will project resistance and put a little ball on my screen and I'd get the same effect as this thing. Actually my effect would be better cause I could get resistance in every direction my screen has available whereas this thing only has resistance in the down direction. The only reason it's 3D is because they are using a concave mirror that you could buy are Sharper Image 15 years ago. If you look at it from the wrong angle, the entire thing would look wrong. At least they could try to use some current 3D technology.
I guess my problem is the application that they are putting this on. The important technology here is the device that causes focused sound that goes as far as to project force. There is nothing in this device that speaks of holography except the way they are presenting it." (Brandon 8/7/2009 9:45:18 AM) |
| "I'd assume the ultrasound is just tricking your nerves into perceiving pressure. If it can actually move objects, that's a whole additional level of gee whix." (virtual arm wrestling 8/7/2009 10:27:58 AM) |
| "They show it moving paper. Paper is an object." (Brandon 8/7/2009 12:15:50 PM) |
| "They show it actually exerting force. (as demonstrated with the paper) It only does so in one direction, but they've also only got one ultrasound array. From what they showed, if they used more ultrasound arrays, placed in other locations, they could exert force in more directions. This tech is not about the visual display side, but the _tactile_ display. What you use for the visual side is immaterial to this tech's ability to do what it is designed for. (tho if it were combined with a Cheoptics Display, that'd be pretty impressive)" (Ashley 8/8/2009 7:59:20 AM) |

The concave screen was for ease of public display, previous videos showed it in use with a HMD. It could be extended using emitter arrays on multiple surfaces to provide sensation from any direction. As it it based on phased arrays, assuming you have sufficient array power you can project 'soundoids' (think plasmoid but with acoustic rather than EMwaves, I'm not sure if they've coined their own term for it) in any non-enclosed location. you could place an object in a cupped hand, but not in two cupped hands enclosing a space. Such a limitation is relatively minor in the face of the complete lack of need for a physical stand-in object which is the current sate of the art.
It is DEFINITELY not "2d", in that it is based around the focussing of multiple emitters to a virtual (and VARIABLE) plane. Simply scanning this focus plane through a volume would provide depth. Phased arrays are real nifty emitters, and can do some crazy things. Go look up modern phased array radars, and larger arrays like Project HAARP." ( 8/8/2009 7:54:32 AM) |
| "My problem with the article is not with the technology, but rather the way it was presented. The fact that it was presented as both holography and as a display are both wrong. This is a sound device." (Brandon 8/10/2009 10:56:29 AM) |
