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. magnetic field control circuit, the data can be transferred to the information processor side through the tablet. Further, a CPU executes the processing corresponding to the result of analyzing a sound.
