With a single bead of plastic, scientists tease interactive 3D

British scientists have developed moving three-dimensional images with sound and touch sensations based on a tiny plastic bead moved at high speeds.

... the emerging technology has been able to produce small recreations of objects that people can interact with, and it is expected to have applications in architecture, design, biomedical imaging and medicine.

That reminds me of those displays at department stores in the '60s where they would have a vacuum cleaner suspend a beach ball in mid air.

Who knew that the Sears floor staff were actually futuristic scientists?

The Glass Bead Game is set in a distant, possibly post-apocalyptic future and tells the life story of Joseph Knecht, who at the beginning is a young initiate in Castalia, a monastic order of secular scholars. His fellow monks study various subjects, but they are linked by a vaguely defined activity called the Glass Bead Game. Hesse never explains the game, except to say that it involves all forms of knowledge, particularly mathematics and music. Knecht works his way up in the order, finally becoming the Magister Ludi, or master of the game.

All the while, Knecht is in touch with a childhood friend, Designori, who hails from a wealthy family and becomes an influential politician. Through a series of dialogues with Designori, Knecht becomes disillusioned with his life in Castalia, and at the end of the book leaves the order to become a tutor to Designori’s son.

I read that book. It was "some time ago" and it was only that YouTube video from williegoat that prompted me to remember that.

Other than the book title itself, the experience of it is was all lost to (my) immediate recall. Now it's a moot point (what I might eventually have come to remember about it) because I looked at this very brief review.

Herman Hesse’s The Glass Bead Game
"The difference between scholarship and wisdom."

PROVE IT.

You are already a documented LIAR here regarding books that you claim to have read and demonstrably DIDN'T.

Science-fiction movies portray volumetric systems that provide not only visual but also tactile and audible three-dimensional (3D) content. Displays based on swept-volume surfaces, holography, optophoretics, plasmonics or lenticular lenslets can create 3D visual content without the need for glasses or additional instrumentation. However, they are slow, have limited persistence-of-vision capabilities and, most importantly, rely on operating principles that cannot produce tactile and auditive content as well.

Here we present the multimodal acoustic trap display (MATD): a levitating volumetric display that can simultaneously deliver visual, auditory and tactile content, using acoustophoresis as the single operating principle.

Our system traps a particle acoustically and illuminates it with red, green and blue light to control its colour as it quickly scans the display volume. Using time multiplexing with a secondary trap, amplitude modulation and phase minimization, the MATD delivers simultaneous auditive and tactile content. The system demonstrates particle speeds of up to 8.75 metres per second and 3.75 metres per second in the vertical and horizontal directions, respectively, offering particle manipulation capabilities superior to those of other optical or acoustic approaches demonstrated until now. In addition, our technique offers opportunities for non-contact, high-speed manipulation of matter, with applications in computational fabrication and biomedicine.

Why do I obsessively cut and paste things from the internet that I really don't understand? (Ronaldphoresis)

Why do I bizarrely capitalize words in my sentences like "Original Post"?

Why can't I just be normal and not psychotic?

"The Venerable Bead"... hey, did you see that? You probably saw it, but did you really "see" it?

That's like the inimitable Control Enthusiast himself, Patrick Warburton, for National Car Rental.

Oh wait. That was me.

I remember it well!
That and the cartoon game Dragons Lair/Space Ace were visually amazing back than!

But of all the games, my favorite was Major Havoc:


Go to different planets, enter their maze, find the reactor, set the timer, and get out before you run out of O2 or the reactor blows!

That (obviously) is the abstract or overview from the recent report that I alluded to, in the science journal "Nature." (Not my previous message, but the message before that.)

There have been times when I put up an abstract of this kind, valuing it for its opacity. Its (likely) unintelligibility to anyone who is not involved in that (whatever) kind of research. For effect.

But this abstract is very readable. I do not claim any mastery or competence whatsoever, vis-a-vis some of the particular words and phrases, including (but not limited to) "optophoretics" and "time multiplexing with a secondary trap," but overall, I "get" it, and I put it up here because ... I thought it was important for one or more other members of this online forum?

No, I only used it to bump the thread and in so doing, elicit ... [anyone can take it from there.]

Boondawg really nailed it, with the first remarks that he entered into this conversation.

I have preferred the capitalization of "Original Post" because I think it's an odd or peculiar terminology that does not exist in common parlance, outside of the Internet messages board or online forum space. If I used the all lower case "original post," that could (IMO) all too easily slide by without eliciting the desired interpretation of the message.

But beyond that, "I'm not going to say" (a Carter Page-ism) that there has not been even a single recent instance of a Gratuitous or Idiosyncratic Capitalization that I have indulged in, seeking to express an emphasis or to remark a certain phraseology where an all lower case articulation would very possibly have been deemed by subject matter experts in print and online media as more in line with commonly accepted publishing standards and guidelines, or MILWCAPSAG.
