Traditional QWERTY keyboards are bulky and offer very little in terms of enhancements. Now-a-days soft touch keypads are much popular in the market. These keypads give an elegant look and a better feel. Currently keyboards are static and their interactivity and usability would increase if they were made dynamic and adaptable. Various on-screen virtual keyboards are available but it is difficult to accommodate full sized keyboard on the screen as it creates hindrance to see the documents being typed. Virtual Keyboard has no physical appearance. Although other forms of Virtual Keyboards exist; they provide solutions using specialized devices such as 3D cameras. Due to this, a practical implementation of such keyboards is not feasible. The Virtual Keyboard that we propose uses only a standard web camera, with no additional hardware.
