Abstract

The present invention provides a graphical data entry system for accepting and processing hand sketches and writings such that the user can quickly specify graphical objects in a drawing on a hand-held, mobile computer with a relatively compact screen. A viewing glass is provided by the graphical data entry system which enables the user to pan and zoom into a specific display region of the drawing. An object classification and recognition capability is provided to allow the present invention to recognize objects being sketched by the user and to convert the hand sketches into computer aided design (CAD)-like drawings. Further, the present invention integrates speech recognition and keyboard data entry to provide a user friendly computer system. Additionally, the graphical data entry system of the present invention can be used in conjunction with a camera to annotate pictures taken with the camera. The present invention can operate with digital cameras, APS-compatible cameras and conventional cameras which work with silver halide type films. Further, the drawing system of the present invention can be used in two-way messaging systems to support graphical paging requests and replies. The present invention also supports an intelligent agent operating with remote computers to locate and respond with responsive information, as specified using the graphical data entry system of the present invention.
