What is the projection keyboard?

Projection keyboard, also known as a virtual keyboard, is a projection that looks and works like a keyboard; When he touches, the system picks up your fingers and registers them as keyboards. All units of the projection keyboard are made to be wireless, giving them greater operating lengths than cable keyboards. Two keyboard registration systems are used to register keyboards; One uses the camera sensor to capture the finger movement, while the other uses an infrared sensor to detect the finger movement. Along with the keys, most of these systems also provide virtual mouse and piano projection. The most popular use of these keyboards is for mobile devices, but desktops can also use them. This allows the keyboard to have a much longer operating distance than the cable keyboard. Bluetooth® technology has also been integrated into computers for years, so the computer should not have trouble picking up the keys.

There are two versions of the projection keyboard, although both create the same result. The most common version projects the keyboard using the laser and when the user moves the virtual key, the camera records the fingers of the fingers. From this image, the camera uses coordinates to select the right key and enter a computer or device. The second type projects the keyboard and designs an infrared beam over it. When the key is hit, the sensor detects where the infrared light was interrupted by finger movement and records the appropriate keyboard section.

Most projection keyboard units are able to project two other devices: mouse and piano. The virtual piano works in almost the same way as the virtual keyboard. When someone is pushing the piano key, the system detects the movements and corresponds to the appropriate sound. With the virtual mouse, the user moves the mouse with the mouse and will respond by moving the mouse pointers around the computer screen.

keyboard projection units are mostlyThey use it on mobile devices and are considered a replacement for a folding keyboard and a mobile keyboard. Mobile devices that have digital keyboards or devices on the device screen can use this system if the user is difficult to write on a small digital keyboard of the device. Although this keyboard is mainly used with mobile devices, it can also integrate into desktop computers to replace the cable keyboard.
