Abstract
The disclosure relates to a method for entering commands and/or characters for a portable communication device equipped with an input device comprising a tilt sensor, including the steps of determining a motion of the portable communication device through measurements of the tilt sensor calculated in reference to a neutral position of said tilt sensor; and deducing from said motion an associated command and/or character. According to the disclosure, the method further includes a preliminary calibration step triggered by a user of the portable communication device, consisting in defining the neutral position as being the current position of the sensor at the time of triggering the calibration step.
