Miracast is utilised in many devices and is used or branded under various names by different manufacturers, including Smart View (by Samsung), [3] [4] SmartShare (by LG), screen mirroring (by Sony), Cast (in Windows 11) and Connect (in Windows 10), wireless display and screen casting.
scrcpy (short for "screen copy") is a free and open-source screen mirroring application that allows control of an Android device from a desktop computer. [2] The software is developed by Genymobile SAS, a company which develops Android emulator Genymotion. [3] The application primarily uses the Android Debug Bridge (ADB) via a USB connection to ...
A projector or image projector is an optical device that projects an image (or moving images) onto a surface, commonly a projection screen. Most projectors create an image by shining a light through a small transparent lens , but some newer types of projectors can project the image directly, by using lasers .
A video projector is an image projector that receives a video signal and projects the corresponding image onto a projection screen using a lens system. Video projectors use a very bright ultra-high-performance lamp (a special mercury arc lamp ), Xenon arc lamp , metal halide lamp , LED or solid state blue, RB, RGB or fiber-optic lasers to ...
Sony makes a screen [6] that appears grey in normal room light, and is intended to reduce the effect of ambient light. [7] This is purported to work by preferentially absorbing ambient light of colors not used by the projector, while preferentially reflecting the colors of red, green and blue light the projector uses.

We assume that the spinning mirror is centered at the origin and that its axis of rotation is the vertical y-axis, with the video projector at the nodal point P above the mirror as in top figure. We further assume that the viewpoint for which the correct perspective should be obtained is at a height h and a distance d from the y axis.
An interactive whiteboard (IWB) device can either be a standalone computer or a large, functioning touchpad for computers to use. Interactive whiteboards are widely used in classrooms, boardrooms, and training environments, providing an innovative way to share information, facilitate discussions, and enhance the overall learning or business communication experience.
In contrast, a modern LCD or DLP projector often uses an Ultra-high-performance lamp which has a higher luminous efficacy and lasts for thousands of hours. [5] A drawback of that technology is the warm up time required for such lamps. Older overhead projectors used a tubular quartz bulb which was mounted above a bowl-shaped polished reflector.
