While unlikely to replace the desktop computer monitor, so-called walk-through displays could eventually be put to use in product showrooms, museums, and military training facilities.
haha, what really got me is that caption: "The company that makes heliodisplay images says they allow a hand or finger to manipulate them. "Originally posted by ahrkron
I know this can hardly be considered a contribution to the thread, but: WOW!
The extent of information we are disclosing at this time is that the device modifies the properties of air within a localized environment. Air comes into the device, is ejected and illuminated using a proprietary technique in which the photons and air produce the image. There is no harmful gas or liquid. Nothing needs to be refilled. It is just ambient air. The image, furthermore, is interactive as a virtual touchscreen allowing a hand or finger to be used as a mouse.
When we commercialized the product, we expect that the price will be very competitive with an equivalent sized plasma screen.
By blowing a consistent enough stream of air, then lighting it (how? laser?) you could feasibly generate an image, with the 'air modification' being something like ionization(?), hence charged.Originally posted by Greg Bernhardt
(SNIP) How in the world? So this mean you can physically manipulate the output of the projectors? I would be extremely interested in exactly how it modifies the air. (SNoP)
The video screen is created using a technology known as holographic projection. It uses a combination of laser beams, mirrors, and lenses to create an image that appears to float in mid-air.
Yes, the holographic projection technology allows the video screen to be viewed from multiple angles without losing image quality. This makes it ideal for public events and gatherings.
The content is displayed on the video screen using a computer or media player that is connected to the holographic projector. The projector then projects the content onto the laser beams, creating the image in thin air.
Since the video screen is created using laser beams, it can be seen even in bright lighting conditions. However, the image may appear slightly dimmer compared to darker environments.
Yes, the video screen can be used for interactive purposes by incorporating touch-sensitive technology. This allows users to interact with the video screen as they would with a regular touch screen, making it suitable for presentations and exhibitions.
