Abstract

Screenless video describes systems for transmitting visual information from a video source without the use of a screen. Screenless computing systems can be divided into three groups: Visual Image, Retinal Direct, and Synaptic Interface.Visual Image screenless display includes any image that the eye can perceive. The most common example of Visual Image screenless display is a hologram. 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 airplanes (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. Google has proposed a similar system to replace the screens of tablet computers and smartphones.
