Albany, NY -- (SBWIRE) -- 09/14/2018 -- A virtual keyboard can be defined as a device or technology that employs computer software for on screen keyboard or keyboard projected with the help of LASER or LED light on a non-reflecting surface. A keyboard is projected on a surface and the key-press is detected with the help of optical detectors. Moreover, advanced technologies such as on screen keyboard uses resistive or capacitive touch screen to detect the key-press.
Amongst the two technologies used in the virtual keyboards, the projected type of virtual keyboard uses a wireless module connected to a phone or PDA through Bluetooth or Wi-Fi technology which incorporates a source of light to project the image of the standard keyboard on a non-reflective surface and sensor or detector to detect the motion of fingers. Whenever, a user moves his fingers on the projected image, the detector sends a signal based on the touch to the controller incorporated in the wireless module, thereby detecting a key press. However, the other technology used for virtual keyboard, projects the keyboard on the screen of the computer or a mobile phone. In this technology, the users can use the input devices such as mouse to press the key for typing. With the advances in technology, the on screen virtual keyboards are being used on a larger scale as compared to the projected type of virtual keyboards.

With the increasing use of touch screen mobile devices and portable computers, the on-screen virtual keyboard has become an integral part of these devices. Moreover, the on-screen virtual keyboard are also being used widely on the automated teller machines, manufacturing machines such as CNC machines, advanced automotive dash boards and smart television. As a result of above mentioned factors, the on-screen type of virtual keyboards are expected to contribute for major share of the global virtual keyboard market. The projected type of virtual key boards can be used in many applications to reduce the risk from key-press logging, where the movements of the user's hand can be used to track the password or any security related information, such situations may arise while using keyboards to input password in banks and ATMs. In the projected type virtual keyboard, the position of keys on the board, keeps on changing periodically. This feature can help keeping the credentials safe from the system malware. As a result of above mentioned features, the projected type virtual keyboards are expected to generate substantial demand from the government and defense segment of the virtual keyboard market.
