ABSTRACT:
This invention is directed to the provision of a data input device that is operated by a novel method of inputting the force applied on a force sensor as polar coordinate data and subjecting the data to input processing which utilizes the r value and the θ value.A portable telephone1detects the force applied on a force sensor51of an input unit50as rectangular coordinate data and converts the detected rectangular coordinate data into polar coordinate data. Then, with reference to an allocating table that has recorded characters and ranges of θ values to which the individual characters are allocated, the character allocated to the obtained θ value is selected. Then, when the r value larger than a prescribed threshold is input, the entry of the selected parameter is determined.
