Input device utilizing virtual keyboard
First Claim
1. An input device utilizing a virtual keyboard, which enables data to be input by designating at least one input-position corresponding to at least one key indicated in an image of a key arrangement displayed on a display means, by using a designating means, said input device comprising:
- an input-symbol defining means for defining a form and a meaning of each of input-symbols drawn by said designating means across said image of said key arrangement; and
a symbol recognition means for discriminating said input-position and related input-symbol drawn across said image of said key arrangement said input-position on the basis of information defined by said input-symbol defining means and for generating at least one input-code corresponding to at least one input-code in a real keyboard, wherein said input device is operative to generate a specified input-code in accordance with a combination of said input-position and said related input-symbol discriminated by said symbol recognition means, and wherein said input device is operative to display characters or symbols corresponding to said specified input-code on said display means.

Abstract
An input device, which utilizes a virtual keyboard, includes a device for designating at least one input-position in a virtual keyboard displayed on a display; an input-symbol defining device for defining a form and a meaning of each input-symbol drawn by the designating means (e.g., a write-pen); and a symbol recognition device for discriminating the input-position and related input-symbol drawn at the input-position on the basis of information defined by the input-symbol defining means. The input device generates a specified input-code in a real keyboard in accordance with a combination of the input-position and the input-symbol, and displays characters or symbols corresponding to the input-code on the display means. Preferably, the form of each input-symbol includes a length of a segment drawn by the designating device and a direction in which the segment extends. Further, the meaning of each input-symbol includes information about a correspondence between the form of each input-symbol and a method in which at least one key in the real keyboard is depressed.
