Touch screens are easy to learn to use, fast and results in low error rates when interfaces are designed carefully\cite{fa}. But typing on touch screen with virtual keyboard is much shower, error full and gives poor user interaction \cite{aa}. Every systems interface and interaction should give a pleaser to use it but touch screens virtual typing interface does not afford a minimum interaction with user. Since 1870 QWERTY layout is applying for mechanical typing and utilized for mobile interface with heavy visual and auditory cues feedback but on touch screen surface user can not feel the controls \cite{aa}.
