To get back on topic...I have emailed the company that makes this, and they have yet to reply after about 2-3 weeks, kinda strange if you ask me...

ya, what the heck, 4-d?

[James S]

length, breadth, width, and duration are the four known dimensions.

1D) a single point, 2D) a line, 3D) an object with the previous AND depth, and 4D) an object with the previous AND time.

Some scientists argue that we now know of 12 dimensions, I can't recall all of them. a lot deal with time, subspace/dark matter, and other space phenomenon.

Paul, hologram can't be touchable. It makes no sense.

Moose, that projector from FF:TSW was my first association when I read this article [and it's orange too ;]]. But I don't see any relation with time... it was probably the same input solution, but this time cameras were 3D and were locating fingers precisely [or how do you spell that].

[Paul]

well thats how it works, it sees the changes in the light, doesnt it?

they had one on enterprise recently. it was a holographic display that stuck up vertically and reed interacted with it by touching it.

[zahn]

Paul, was that display projected from both up and down? Whatever, changes in the light probably won't be to precise... Sensors should be from both up/down and side. If it will be on one direction [vertical or horizontal], then it receives only one coordinate, X or Y. To locate the cursor [touch position] it needs two coordinates...<font size=1 color=#3355AA>

[Paul]

it was from below, a small device about a third the size of the resulting hologram.

but hey, its 31st century technology, i doubt they'd still use cameras to get the job done...

[zahn]

If it was only from down, then it needs work :] "Touching" a projected display will cause lose of image over your finger.
