Shegdar * , Mr.Z. M.Shaikh * Computer Science and Engineering, NK Orchid College of Engineering &Technology,Solapur(Maharastra), India ABSTRACT Now a days, most of the smart phones having touch screen instead of traditional keypad. The virtual keyboard is replaced with traditional keypad. There are various such keyboards that are present in the market including Devanagari language. Devanagari is a script used by many Indian languages like Hindi, Marathi, Nepali and Sanskrit, but typing on such touchscreen is a little difficult for new users. The problems with touchscreen are: - they are highly responsive, Touch area is precise, precision is required for typing and users are experiencing many errors in typing keys with their thumb so as a result, typing on such screen is very slow. The solution to these problems is to use an Intelligent keyboard. An Intelligent keyboard is a virtual keyboard used for touch screen smart phones and tablets where the user enters words by click on one or two letters of the word. The overall objective of this paper is to provide knowledge that can help to improve user experience of Devanagari text entry with an Intelligent keyboard in touch screen mobile devices. KEYWORDS: Smartphone, touch screen, virtual keyboard, Devanagari Script. INTRODUCTION A touchscreen is an input device normally layered on the top of an electronic visual display of an information processing system. Touchscreen technology is the direct manipulation type gesture based technology. A device which works on touchscreen technology is called as Touchscreen. A user can give input or control the information processing system through simple or multi-touch gestures by touching the screen with a special stylus/pen and-or one or more fingers. The user can use the touchscreen to react to what is displayed and to control how it is displayed (for example by zooming the text size). The touchscreen enables the user to interact directly with what is displayed, rather than using a mouse, touchpad, or any other intermediate device (other than a stylus, which is optional for most modern touchscreens). A touchscreen is an electronic visual display capable of ‘detecting’ and effectively ‘locating’ a touch over its display area. It is sensitive to the touch of a human finger, hand, pointed finger nail and passive objects like stylus. Because of touchscreen devices virtual keyboards are used instead of traditional physical button based keyboards. The virtual keyboard technology uses sensor technology and artificial intelligence to allow users work on any flat surface as if it were a keyboard. Virtual keyboard with InScript (Indian Script) is the standard keyboard layout for Indian scripts using a standard 104 or 105 key layout. This is the standard keyboard for 12 Indian scripts including Devanagari, Bengali, Kannada, Malayalam, Oriya, Tamil and Telugu and others.
