Screenless Display Technologies:
It may sound like an oxymoron, but a screen-less display is a kind of technology that could be utilized in the very near future. Scientists and technology firms are finalizing a range of devices and forms of technology that allow you to view images without the use of a screen. These devices come in the form of projection devices and hologram machines, and whilst they all offer something different, they are all a part of the next generation of technology.
The first screen-less display that needs mentioning is Google Glass. This device has been tested for the past year, and some lucky individuals have even got their devices already. Google Glass sits on the face like a pair of glasses, and on one eye it has a block of glass that allows you to see augmented reality. Images can be displayed right in front of your eye, as well as text and information about objects and places that are in front of you. This technology is only in its early stages, but definitely shows that screen-less displays will become a natural form of media consumption in the future.
It is expected that Google Glass will become fully commercially available in 2014, and some minor changes have been made recently with the design. Namely, the bone audio system, which provides audio by vibrating the bones in your face, has been replaced with a single headphone. It is reported that this is a result of the bone audio technology producing too low a volume.
Holographic technology has unfortunately not gone very far past trickery with mirrors. This form of photography provides a three dimensional image, and some technologies are now creating images using lenses, helium neon and holographic film. Scientists will not have a fully working holographic table prepared for market any time soon, but it is definitely on the cards for the future. The only downfall of this kind of system, however, is that the orientation and viewing angle of a viewer will determine the quality of the image that can be seen – meaning that so far, holographs are not ideal for media or information consumption.
Holographs can work by using a laser beam that can interfere with an object beam. When these two beams get in the way of one another, they can create what looks like a three dimensional image. This image can then be recorded for processing by recording the diffraction of the light and the way in which the beams interfere with one another.
The Oculus Rift is an amazing piece of kit that is already available to purchase. This is a headset that completely blocks out the real world, and instead replaces what you see with a pre-programmed image. This is the ultimate virtual reality machine that displays video and appropriate sounds, and uses its accelerometer to ensure that it feels totally real. If you move your head left, you will see the image that is to the left in the virtual reality scenario. This kind of technology has a plethora of uses, and today it is constantly being updated and improved to provide you with the very best in screen-less display technology.
