SWITCH ACTUATING DEVICE, MOBILE DEVICE, AND METHOD FOR ACTUATING A SWITCH BY MEANS OF A NON-TACTILE GESTURE

摘要

The invention relates to a method for operating a switch actuating device (11), having the following steps: outputting the pixels of the signal excursions (49, 79) caused in the approach phase (3) and the signal excursions (50, 80) caused in the translation phase to a signal analyzing unit, wherein the non-tactile gestures are performed using the heat-emitting part, and a waiting level which has a lower value than the values of the extreme values of the signal excursions is reached between the signal excursions during the waiting phase (4) of the signal; monitoring the signal and identifying the occurrence of a sequence of the signal excursions and the signal waiting level lying chronologically between the signal excursions; proceeding with the next step as soon as the sequence has been identified; checking whether the signal excursions caused in the approach phase have a direction opposite the signal excursions caused in the translation phase; proceeding with the next step if the check is positive; checking whether the time offset of the signal excursions caused in the approach phase lie within a first specified span of time; proceeding with the next step if the check is positive; and checking whether the time offset of the chronologically first and the chronologically last signal excursion caused in the translation phase lies within two thresholds, the lower threshold of which is larger than null.
