A keyboard as disclosed is equipped with sensors or sensing structures for perceiving a finger's presence. It allows a single manual movement applied to a button, such as a key press action, to select any one of the optional characters overlaid on a button for inputting. This provides an efficient, flexible, and accurate text entry method. Such a keyboard or portable device avoids or lessens the problems of misspelling of predictive texting and slow typing speed associated with the conventional multi tapping single entry techniques. Furthermore, it can be implemented with other existing text entry techniques together in the same phone. Since this proposed technique, known as the single tap selective entry technique, conforms to the commonly accepted pattern of using a large-sized computer keyboard and requires little or no training, it is easier to be adopted by public for a more friendly, precise and speedy messaging operation.
