- 1. SCREENLESS DISPLAY our imaginations dressed into reality Presented By, J Mowlidharan
- 2. WHAT IS SCREENLESS DISPLAY? ❑Screenless display is the present evolving technology in the field of the computer-enhanced technologies. ❑It is going to be the one of the greatest technological development in the coming future years.
- 3. ORIGIN OF SCREENLESS DISPLAY • 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.
- 4. FIRST SCREEN-LESS DISPLAY • 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.
- 5. TECHNOLOGY USED IN SCREENLESS DISPLAY • Interactive Projection and Visual Display System The biggest impact in screenless technology has been seen in the use of optical technology. Optical technology enables personal screenless displays by projecting images and data from computers, DVD players, or VCRs into the viewer's eye, displaying them in the visual field of the viewer. For example, Microvision Inc. has created helmet mounted displays in which an Army tank commander can view the surrounding area from topside while still viewing a translucent map that floats a couple of feet away.
- 6. TYPES OF DISPLAYS Screenless computing systems can be divided into three groups: • Visual Image • Retinal Projection • Synaptic Interface/Brain Computer Interface
- 7. VISUAL IMAGE • Any screenless image that the eye can perceive. A hologram is the most common example of visual image screenless display • 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.
- 8. Projection Window • • • It having two terminal which project the source. Air works as interface. Resolution is very high.
- 10. ❑ Light projected directly to retina ❑ Prevents snooping ❑ Not limited by physical size ❑ More secure to access data from outsiders. Retinal Display having:
- 11. SYNAPTIC INTERFACE ▪ In Synaptic 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. Synaptic Interface having:- • Brain Computer Interface or BCI • cochlear implant for the eyes • No light projection • Image sent straight to brain
- 12. Camera sends images to electrode implant
- 13. Advantages and disadvantages of the technology • Low power 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
- 14. AFFECTS OF SCREENLESS DISPLAY • 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
