Abstract: An input device which includes plural inputting units, each accepting external information, including a unit for recognizing an input time of input information accepted via each of the plural inputting means; a unit for dividing or merging the input information into a predetermined primitive analysis unit, to obtain a recognition result; a unit for estimating the input time of a unit recognition result, by using an estimating method predetermined for each of the inputting units; and a unit for collecting some of the recognition results whose estimated input times are close to one another, and outputting the collected information as a semantic analysis unit. An input content is specified by collecting plural pieces of input information being signals input from plural inputting units.

Abstract: It is an object to provide a computer system including a practical input device which can be operated with more natural sense. The present input pen which is used in combination with a tablet includes: a speech recognition unit for analyzing a speech sound, which is fetched in through a microphone, as a command or the like; an image reconfiguring unit for composing, after correcting image distortion generated due to inclination of the pen body for each image in the vicinity of a pen head which is photographed along with the strokes of the input pen by a CCD camera, the series of images into a general image; and a reference line generating circuit for lasing a laser beam with which a projected image utilized to calculate an angle of inclination is formed onto a face of an object of photographing. In addition, since an oscillation circuit generates a magnetic field corresponding to the data forming the general image on the basis of control by an a.c.

Abstract: A functional relation between components which can be extracted from an already existing program in advance is automatically extracted by a computer, or such a functional relation which cannot be extracted is defined by a developer, so that the preparation of a program by combining the components is assisted. A dictionary registration unit reads a source code file, analyzes, extracts a component definition, and extracts from the component definition information a counterpart component name, interface name, and interface definition, and registers component name, counterpart component name, interface information of the interface name, and interface definition body in a dictionary. Furthermore, when there is no source codes, the developer inputs the interface information from an input-output device, and registers in the dictionary.
