Introduction
The killer feature for me is the laser keyboard. If Apple were able to put such a feature in the iPhone 5, we wouldn’t need Bluetooth iPhone keyboards, and could jump into productivity mode anywhere there was a flat surface. You have to admit the swipe out gesture to turn the laser keyboard on is pretty sweet.
While a holographic display would be amazing, I’d prefer a built-in projector that can display an HD video on whatever wall is closest. You can already purchase Pico projectors that do this, and Apple has filed patents showing that the company is investigating integrated projectors. We saw Pico projectors in smartphones at CES 2010, so it is possible, but not in such a slim package — yet.

The most interesting stuff that Ataman explores are the ideas of a holographic display projected into the air from the iPhone and a laser keyboard projected on to a table top from the iPhone. Interestingly enough, the video shows theses two ideas separately, but if you put them together then you can see where the smartphone becomes a full PC replacement (a concept I've been talking about again recently).
Ataman CEO Premed Mode Shantharam said, "We at Ataman are massive fans of the iPhone and are eagerly awaiting the release of iPhone 5. Meanwhile, going by the buzz the iPhone 5 is generating, we felt it's a good time to launch a concept such as this, and showcase our vision of key features of an iPhone 5 or subsequent models could have in the future."
If you could pick one way out there feature to add to the next iPhone, what would it be?
Concept Of IPHONE5
Although there's not really a question that the Apple iPhone has made it as a platform, some of the passion and high expectations for future development of the product were on full display recently as a 3D animation company called Ataman Studio created what it refers to as a concept design for iPhone 5.
While the concepts that Ataman shows off in its one-minute video are definitely not going to show up in the iPhone 5 -- which is expected to launch in October there are some compelling ideas that could show up in the iPhone and other smartphones within the next 3-5 years.
Laser keyboard
A laser projection device approximately the size of a computer mouse projects the outline of keyboard keys onto a flat surface, such as a table or desk. This type of keyboard is portable enough to be easily used with PDAs and cellphones, and many models have retractable cords and wireless capabilities. However, sudden or accidental disruption of the laser will register unwanted keystrokes. Also, if the laser malfunctions, the whole unit becomes useless, unlike conventional keyboards which can be used even if a variety of parts (such as the keycaps) are removed. This type of keyboard can be frustrating to use since it is susceptible to errors, even in the course of normal typing, and its complete lack of tactile feedback makes it even less user-friendly than the cheapest membrane keyboards.
Technology :HOM:
High-penetrated optical material with unique microstructure.HOM technology, designed in Denmark, creates a high-definition image to allow viewing audience to experience a vivid image （ see through ） and an unreal image （ look at ） through the screen. HOM technology enables maximum uniform high brightness and high contrast without hot spots or image washout against ambient light.
Quality:•High Transmittance•High Contrast•High Resolution•Good Color Uniformity•Anti-Ambient Light
Holography:-
Holography was invented in 1947 by the Hungarian-British physicist Dennis Gabor (Hungarian name: Gábor Dénes), work for which he received the Nobel Prize in Physics in 1971. Pioneering work in the field of physics by other scientists includingMieczysław Wolfke resolved technical issues that previously had prevented advancement. The discovery was an unexpected result of research into improving electron microscopes at the British Thomson-Houston Company in Rugby, England, and the company filed a patent in December 1947 (patent GB685286). The technique as originally invented is still used in electron microscopy, where it is known as electron holography, but optical holography did not really advance until the development of the laser in 1960.
History
The development of the laser enabled the first practical optical holograms that recorded 3D objects to be made in 1962 by Yuri Denisyuk in the Soviet Union and by Emmett Leith and Juris Upatnieks at University of Michigan, USA. Early holograms usedsilver halide photographic emulsions as the recording medium. They were not very efficient as the grating produced absorbed much of the incident light. Various methods of converting the variation in transmission to a variation in refractive index (known as "bleaching") were developed which enabled much more efficient holograms to be produced
Specular holography is a related technique for making three-dimensional images by controlling the motion of specularities on a two-dimensional surface. It works by reflectively or refractively manipulating bundles of light rays, whereas Gabor-style holography works by diffractively reconstructing wavefronts.
Most holograms produced are of static objects but systems for displaying changing scenes on a holographic volumetric display are now being developed.
Holograms can also be used to store, retrieve, and process information optically.
In its early days, holography required high-power expensive lasers, but nowadays, mass-produced low-cost semi-conductor lasers, such as those found in millions of DVD recorders and used in other common applications, can be used to make holograms and have made holography much more accessible to low-budget researchers, artists and dedicated hobbyists.
It was thought that it would be possible to use X-rays to make holograms of molecules and view them using visible light. However, X-ray holograms have not been created to date
Holography is a technique which enables a light field, which is generally the product of a light source scattering off objects, to be recorded and later reconstructed when the original light field is no longer present (due to the absence of the original objects). Holography can be thought of as somewhat similar to sound recording, whereby a sound field created by vibrating matter, like musical instruments or vocal chords, is encoded in such a way that it can be reproduced later without the presence of the original vibrating matter.
Holograms are recorded using a flash of light that illuminates a scene and then imprints on a recording medium, much in the way a photograph is recorded. A hologram, however, requires a laser as the light source, since lasers can be precisely controlled and have a fixed wavelength, unlike white light, which contains many different wavelengths.
A shutter is required when taking a photograph to limit the time in which the film is exposed to light. Holography also requires a specific exposure time, and this can be done using a shutter, or by electronic timing of the laser.
This laser beam is generally aimed through a series of elements that change it in different ways. The first element is a beam splitter, which divides the beam into two identical beams, each aimed in different directions:
One beam, known as the illumination or object beam, is spread using lenses and directed onto the scene using mirrors, in order to illuminate it. Some of the light scattered (reflected) from this illumination falls onto the recording medium.
The second beam, known as the reference beam, is also spread through the use of lenses, but is directed so that it doesn't come in contact with the scene, and instead travels directly onto the recording medium.
DIGITAL CUBES
Digital cubes can be formed by coding and decoding process
These are digitally physical which can be visible through uv rays.
By obsorbing high penetrated lasers these can form a shape which we defined
An high programming process is involved behind this technology
Coding and decoding
The binary coding and decoding is a process which includes high programming
We can code and decode the digits to enable a process
DIGITALIZATION
Experiments are going on this process.The scientists are saying that they are launching it with in 4-5yrs.
If it is possible in 4-5yrs,we can see a digital man surviving in us.
LASERS
The common thing we observed here is lasers.
In every process we are using high penetrated lasers
Lasers are of different wave lengths and densities
Each laser is useable in every process
