METHOD OF GENERATING INPUT DATA

摘要

A method for use in conjunction with touchpad including a depressible cover and a detection circuit for capacitively detecting a position of a user's finger or stylus on the cover and for resistively detecting a position of a user's finger or stylus when the cover is being depressed comprises the following steps for generating input data for a processor-controlled application: a) detecting, through a resistive pressure measurement; whether the cover is depressed or not; b) if it is detected that the cover is depressed, carrying out a resistive detection mode, the resistive detection mode being (unambiguously) associated to a hard-touch action of the processor-controlled application, the resistive detection mode including performing a resistive position measurement and computing position information data based upon the resistive position measurement; c) if it is detected that the cover is not depressed, carrying out a capacitive detection mode, the capacitive detection mode being (unambiguously) associated to a light-touch action of the processor-controlled application, different from the hard-touch action, the capacitive detection mode including performing a capacitive position measurement and computing position information data based upon the capacitive position measurement; d) making available to the computer-controlled application (as input data) the position information data and an indication whether the position information data has been computed in the resistive detection mode or in the capacitive detection mode, whereby the processor-controlled application is caused to carry out the hard-touch action if said position information data have been computed in resistive detection mode and the light-touch action if the position information data have been computed in capacitive detection mode.
