Abstract
An input device for triggering a function of an electronic device comprises a humidity sensor (12), and a control unit (11). The control unit (11) analyzes a humidity signal (RH) supplied by the humidity sensor (12) and provides a trigger signal (C) subject to the analysis of the humidity signal (RH) for triggering the function of the electronic device (3). In such way, the function of the electronic device can simply be controlled by blowing at the input device (1).
Claims11
Input device for triggering a function of an electronic device, comprising
- a humidity sensor, and
- a control unit for analyzing a humidity signal supplied by the humidity sensor and for providing a trigger signal subject to the analysis of the humidity signal for triggering the function of the electronic device,
- wherein the control unit is adapted for assigning the function to the trigger signal out of a set of functions subject to a characteristic of the humidity signal over time,
- wherein the control unit is adapted for assigning a first function to the trigger signal out of a set of functions if an increase of the humidity signal exceeds a threshold within a time interval and if after a decrease following the increase no new increase is monitored in the humidity signal within a given time window, and
- wherein the control unit is adapted for assigning a second function to the trigger signal out of the set of functions if an increase of the humidity signal exceeds a threshold within a time interval and if after a decrease following the increase a new increase is monitored in the humidity signal within the given time window.
