Screenless display technology allows users to interact with three-dimensional images projected into space without traditional screens. This evolving technology is anticipated to revolutionize how visual information is transmitted, potentially aiding the visually impaired through advanced brain-computer interfaces. Innovations like retinal displays and augmented reality devices like Google Glass demonstrate early applications of this technology.

Origin of screenlessdisplay • 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. • The most profound effect will come from the development of the synaptic interface technology.

- 10. Visual Image • VisualImage screen less display includes any screen less image that the eye can perceive or see. • Example: Hologram • It is made by illuminating with lasers or display in a darkened room with carefully directed lighting. • They're two-dimensional surfaces that show absolutely precise, three-dimensional images of real objects. • If you look at these holograms from different angles, you see objects from different perspectives, just like you would if you were looking at a real object. Some holograms even 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 on how you look at them.
- 11. Visual Image Types •Hologram • Projection on window

- 14. • They arescreen 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 floating in space in front of them.
- 15. Example: Google Glass •The first screen-less display that needs mentioning is Google Glass. • 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.
- 16. How Vision works ReflectedLight Object Light Image We can see things because of reflected light. Light bounces of an object and enters our eye. This light then focuses on the retina to form an image.
- 17. Retinal Projection Projected Image Projector Image In retinal projection, the light does not have to be reflected off of an object. The light is projected directly onto the retina to form an image.
- 18. Synaptic Interface InSynaptic Interface images are sent to an electrode implanted in the brain. And this images can be used to provide vision who have a defect of the eye by bypassing the damaged eye parts and sending a visual signal straight to the brain.
- 19. • Synaptic Interfacescreen less video does not use light at all. • Visual information completely bypasses the eye and is Transmitted directly to the brain. While such systems have yet to be implemented in humans, • success has been achieved in sampling usable video signals from the biological eyes of a living horseshoe crab through their optic nerves, • In sending video signals from electronic cameras into the creatures' brains.
- 20. • Brain ComputerInterface or BCI • cochlear implant for the eyes • No light projection • Image sent straight to brain Synaptic Interface having:-
- 21. Camera sends imagesto electrode implant
- 22. Advantages : • Lowpower requirements • Higher resolution images • Greater portability • Wider angle of view • More accurate color • Greater brightness and better contrast • Ability to present 3D images • Ability to present far-point images • Lower costs
- 23. Affects of screenlessdisplay • Screenless display technology is likely to affect:- • Lighting and projection technologies • Software development/design • Lifestyles of the visually impaired • Career opportunities for the visually impaired

- #9 This is a familiar image. “Help me Obi-Wan Kenobi. You’re my only hope.” Screenless display technology has been depicted in movies for decades. Let’s watch. <play video link>
- #11 A screenless display that is visible to anyone who is looking can be projected as a hologram or onto a clear surface like the windshield of a car or aircraft. Visual Image Any screenless image that the eye can perceive. A hologram is the most common example of visual image screenless display. Arguably, virtual reality goggles (which consist of two small screens but are nonetheless sufficiently different from traditional computer screens to be considered screenless) and Heads-up-display in jet fighters (which display images on the clear cockpit window) also are included in Visual Image category. In all of these cases, light is reflected off some intermediate object (hologram, LCD panel, or cockpit window) before it reaches the retina. In the case of LCD panels the light is refracted from the back of the panel, but is nonetheless a reflected source. Holography—is a technique that allows the light scattered from an object to be recorded and later reconstructed so that it appears as if the object is in the same position relative to the recording medium as it was when recorded. The image changes as the position and orientation of the viewing system changes in exactly the same way as if the object were still present, thus making the recorded image (hologram) appears three dimensional May bring more jobs to the movie business
- #13 Another screenless display type is a retinal display. With a retinal display light is not reflected off an immediate object, like in a visual image, but it is projected directly onto the retina. This can be handy in that one is not limited by physical screen size Because there is no immediate object to be viewed, retinal display can be used to keep things such as financial information safe from snooping eyes. The image can take up the entire field of vision. We’ve seen the potential of retinal displays in movies like Terminator. For a flesh-and-blood person the device can be as simple as eyeglasses.
- #16 We can see things because of reflected light. Light bounces off of an object and enters our eye. This light then focuses on the retina to form an image.
- #17 In retinal projection, the light does not have to be reflected off of an object. The light is projected directly onto the retina to form an image.
- #18 Achieved only in horseshoe crabs. Similar to a cochlear implant, which is a device use to give fair hearing to those without, that receives audio signals and bypasses the damaged portions of the ear and send the sound straight to the brain. Could be used to give vision to the impaired in the near future. The Geordie LaForge character (played by LaVar Burton) in Star Trek: The Next Generation wore such a device.

- #21 A camera that might be incorporated into eyeglasses picks up images. These images are sent to an electrode implanted in the brain. The brain can then interpret these signals, thus creating artificial sight. This can be used to provide vision who have a defect of the eye by bypassing the damaged eye parts and sending a visual signal straight to the brain.
- #23 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 screenless 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. 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 just as the hearing impaired are able to hear through cochlear implants. Imagine a visually impaired person gaining the freedom to drive again! This will also remove occupational limitations of the visually impaired.
