Figure 1: Character Level NLP Applications Different Input Systems for Different Devices Optimized Urdu Touch-Screen Keypad Designs

We live in the age of touch screen gadgets. The future trends also show promising growth for them. Currently available input systems devel-oped for standard PCs have room for improve-ment in efficiency, visibility and usability etc. particularly for Perso-Arabic scripts e.g., Urdu. In addition, small touch screen devices expose users to health hazards. We put forth Ergonom-ics in prime focus to reduce potential health hazards. We proposed distinct touch-screen keypads for different devices that are practically applicable for fast, correct and easy composing. We computed the estimated input time and tap-counts using automated procedure to compare contemporary keypads with our proposed key-pads. Our experiments on a considerably large Urdu corpus reveal results of ample signifi-cance. Our optimization technique for arrange-ment of alphabets and unique interface for data input is extendable and equally applicable to other natural languages
