OLDSCHOOL
Here we see examples of the current display technology…touch screen. Many of us have smart phones or tablet computer with touch screen displays. We predict that our touch screen displays will soon be as “old school” as chalk boards.

Screen less displaysScreen less display is the emerging
display technology. In the previous examples we can see that the user is able to interact with a three dimensional image projected into thin air. This technology seems a fantasy but is quite real.

Introduction One of the more frustrating aspects of modern
communications technology is that, as devices have miniaturized, they have become more difficult to interact with – no one would type out a novel on a smart phone, for example.
The lack of space on screen based displays provides a clear opportunity for screen less displays to fill the gap.
Full sized keyboards can already be projected onto a surface for users to interact with, without concern over whether it will fit into their pocket.

Movie Depiction
This is a familiar image. This picture is taken from the famous movie “Avatar”.Screen less display technology has been depicted in movies for decades.

Types of Displays There are three main types of screen less displays that I
will share in the next presentation.
1. Visual Image- screen less display includes any image that the eye can perceive.
2. Retinal Projection- these systems are a class of screen less displays in which images are projected directly onto the retina.
3. Synaptic Interface/Brain Computer Interface- this screen less video does not use light at all. Visual information completely bypasses the eye and is transmitted directly to the brain.

Visual Image • Visual Image screen less display includes any screen lessimage that the eye can perceive or see.
• Example: Hologram
• It is made by illuminating with lasers or display in a darkened room with carefullydirected lighting.
• They're two-dimensional surfaces that show absolutely precise, three-dimensionalimages of real objects.
• If you look at these holograms from different angles, you see objects from differentperspectives, just like you would if you were looking at a real object. Some hologramseven appear to move as you walk past them and look at them from different angles.Others change colors or include views of completely different objects, depending onhow you look at them.

air touch system. It works by projecting laser beem into humid air
molecules.
We have to move our hands our the humid air where the display is present.

Virtual retinal display They are screen less displays in which images are projected
directly onto the retina of eye
They are distinguished from visual image systems because light is not reflected from some intermediate object onto the retina.
It is instead projected directly onto the
retina.
The user sees what appears to be a conventional display floatingin space in front of them.

Virtual retinal display The VRD was invented at the University of Washington in the
Human Interface Technology Lab in 1991.
The development of high-brightness LEDs have made the displays bright enough to be used during the day and adaptive optics have allowed systems to dynamically correct for irregularities in the eye.

Rift
• It uses a OLED display toeliminate motion blur and judder,two of the biggest contributors tosimulator sickness.
• Low persistence makes the sceneappear visually stable, increasingthe potential for presence.

2. Oculus VR is still in Prototype Stage
It is used for playing immersive games
We can play games in 360 degree Head Tracking.
The Oculus Rift creates a stereoscopic 3D view with excellent depth, scale, and parallax.
Oculus Rift provides an approximately 100° field of view

Synaptic Interface Synaptic Interface screen less video does not use light at
all.
Visual information completely bypasses the eye and isTransmitted directly to the brain. While such systemshave yet to be implemented in humans,
success has been achieved in sampling usable videosignals from the biological eyes of a living horseshoe crabthrough their optic nerves,
In sending video signals from electronic cameras into thecreatures' brains.

Predictions Screen less display technology is likely to affect
1. Lighting and projection technologies
2. Software development/design
3. Lifestyles of the visually impaired
4. Career opportunities for the visually impaired
The most profound effect will come from the development of the synaptic interface technology.
This technology will allow people who are visually impaired to see. Imagine a visually impaired person gaining the freedom to drive again!
This will also remove occupational limitations of the visually impaired.

Experts Say.... Futurist Reto Meier predicts that 10 years from now we will be
able to get transparent LCD patches that will adhere to our eyeglasses and 20 years from now we’ll have contact lenses that project images directly onto our retinas and that we will be able to interface with computers through mind control.
We don’t know about that but the screen less display technologies are sure to affect related technologies related to lighting and projection.
Software will have to be designed to work with the new display technology and output will have to be geared to brighter, more contrasted colors to aid visibility.

Advantages OF Screenless Display Wider angle of view- Retinal projectors will be able to provide
a wider field of view than is possible with display screens.
Greater brightness and better contrast- Retinal projectors can provide higher levels of contrast and brightness than any other display system.
![Page 29: screen less display](https://reader034.vdocuments.us/reader034/viewer/2022042514/55a5c5cd1a28abe66d8b4650/html5/thumbnails/29.jpg)
Advantages OF Screenless Display Low power requirements- Only six diodes are required and a few of a
watts to deliver their images to the user’s eyes.
Higher resolution images- The pixels in the images projected by the diodes can be made smaller than is possible with any CRT or flat panel display, so higher resolution can be achieved. With retinal projectors, the only limitation in the resolution of visual images will be the resolving power of the users’ eyes.
Greater portability- The combination of diodes, lenses, and processing components in a retinal projector system will weigh only a few ounces.

Disadvantages Screenless Display The principle disadvantage is that Virtual retinal
display (VRD) is not yet available in the significannumber.
Prototypes and special experimental models are now being Built, but their cost per unit is high.
The VRD technology is still under progress and Development.

Conclusion:- The future technologies makes our life even better for the
development of mankind in all aspects of life.
We should effectively apply these technologies in reasonable situations and make life easier.
Physically and Mentally challenged people also have to be equipped with latest technologies, to enable them to live a peaceful life.
