Abstract:
A character conversion apparatus for a portable information apparatus, comprising:an inputting apparatus for inputting a character to said portable information apparatus; a character database memory in which character data are stored; a display apparatus for displaying a character or characters inputted from said inputting apparatus or a character of characters obtained by conversion with reference to said character database memory; at least four acceleration sensor means arranged in a distributed manner on the left, right, upper and lower sides of the portable information apparatus for detecting an acceleration thereof when one of different turning operations is performed for said portable information apparatus; each of said acceleration sensors detecting a preset threshold value of an individually associated acceleration, a plurality of commands for character conversion identified by said commands for a character process according to the acceleration sensor that detects acceleration having a higher absolute value than absolute values of accelerations detected by the other acceleration sensors and executing a first identified command when the detected acceleration falls below the threshold value, executing a second identified command different from the first identified command when the acceleration sensor detects more than one consecutive acceleration having a higher absolute value than absolute values of accelerations detected by the other acceleration sensors within a predetermined period of time; and a central processing unit for executing said one of commands for character processing individually allocated to the turning operations for said portable information apparatus which corresponds to the acceleration detected by said acceleration sensor means.
