An electronic device includes a detector, configured to detect a region touched on a touch panel; a calculator, configured to approximate a first touched region, detected by the detector at a first time, and a second touched region, detected by the detector at a second time, to ellipses, calculate angles formed between the major axes of the approximated ellipses and a reference axis of the touch panel, and calculate reference points of the approximated ellipses; and a process controller, configured to control a predetermined process based on changes of the second angle and second reference point, calculated by the calculator from the second touched region, with respect to the first angle and first reference point, calculated by the calculator from the first touched region. |
