Abstracts: Input to small devices is becoming an increasingly crucial factor in development for the ever-more powerful embedded market. Speech input promises to become a feasible alternative to tiny keypads, yet its limited reliability, robustness, and flexibility render it unsuitable for certain tasks and/or environments. Various attempts have been made to provide the common keyboard metaphor without the physical keyboard, to build “virtual keyboards”. This promises to leverage our familiarity with the device without incurring the constraints of the bulky physics. We define a virtual keypad as a touch-typing device that does not have a physical manifestation of the sensing areas. That is, the sensing area which acts as a button is not pre set a button but instead is programmed to act as one. So a sensing area could for example be realized with photo-electric sensors, active finger tracking methods, or a touch pad. The latter is different from a key pad as it does not have a-priori designated areas for buttons. Virtual keypad that employ sensing area for each symbol inherently allow for realization of a soft key. The new virtual keypad technology uses sensor technology and artificial intelligence to let users work on any surface as if it were a keyboard. Virtual keypad lets you easily create text content on almost any existing platform and output it directly to PDAs or even web pages. Virtual keypad, being a small, handy, well-designed and easy to use application, turns into a perfect solution for physical keys.
