In one technology, the keyboard is projected optically on a flat surface and, as the user touches the image of a key, the optical device detects the stroke and sends it to the computer. In another technology, the keyboard is projected on an area and selected keys are transmitted as wireless signals using the short-range Bluetooth technology. With either approach, a virtual keyboard makes it possible for the user of a very small smartphone or a wearable computer to have full keyboard capability. Theoretically, with either approach, the keyboard can be in space and the user can type by moving fingers through the air! The regular QWERTY keyboard layout is provided. 2) Several products have been developed that use virtual keyboard to mean a keyboard that has been put on a display screen as an image map. In some cases, the keyboard can be customized. Depending on the product, the user (who may be someone unable to use a regular keyboard) can use a touch screen or a mouse to select the keys.
