What is the holographic keyboard?

Holographic keyboard usually refers to an electronic device that uses a projected keyboard display rather than a physical input device. While the term "holographic" is used, these devices do not necessarily use real holographic technology, but instead projected the image and use hardware sensing movement to monitor user interactions. This creates an interactive light interface on a flat, two -dimensional (2D) surface, rather than a real fully realized three -dimensional (3D) holographic image. The holographic keyboard can be used with a number of different devices such as desktop and notebook computers, as well as mobile phones, which provides a portable solution for text input needs.

Although some devices can be referred to as holographic keyboards, for the most part such devices do not use real holographic technology. The hologram is formed by means of light with wave disturbance that allows the way the light hit the object to be effectiverecorded. This can then be used if you "play" light recording and re-create this object in 3D space using only light and not the original object. The holographic keyboard usually does not create a fully realized 3D keyboard image, although it is certainly possible, but instead it simply projects a 2D image on a flat surface.

Using a holographic keyboard allows someone to quickly and easily create a virtual keyboard on any non -reflective surface. The holographic keyboard usually consists of a relatively small device, often small enough to fit into the pocket or laptop that projects the keyboard image on the surface. This is usually done by means of basic light and lasers to create the outline of each key and the corresponding letter in each of them. Hardware to track movement on the device is then able to track the user's movements and determine what "key" the user touches.

Interaction ManyThe ive surfaces of Ive can be created in almost the same way as the holographic keyboard, including touch screens. This allows such technology to be quickly and easily transported to almost any place and settings. The holographic keyboard can be connected to different types of hardware to allow the user to create a keyboard for any hardware in any setup. These devices can be connected to desktop and notebook computers, often for aesthetic reasons, and can be more practical when using a mobile phone or similar small device to create a full keyboard in almost any settings.
