TOUCH DETECTION TECHNIQUES FOR CAPACITIVE TOUCH SENSE SYSTEMS |
摘要 |
A technique for recognizing and rejecting false activation events related to a capacitance sense interface includes measuring a capacitance value of a capacitance sensor within the capacitance sense interface to generate a measured capacitance value. The measured capacitance value is analyzed to determine a baseline capacitance value for the capacitance sensor. The baseline capacitance value may be updated based at least in part upon a weighted moving average of the measured capacitance value. The measured capacitance value may also be analyzed to determine whether the capacitance sensor was activated during a startup phase and to adjust the baseline capacitance value in response to determining that the capacitance sensor was activated during the startup phase. |

1. A machine-readable storage medium that provides instructions that, if executed by a machine, will cause the machine to perform operations comprising:
measuring a capacitance value of a capacitance sensor within a capacitance sense interface to generate a measured capacitance value; analyzing the measured capacitance value to determine a baseline capacitance value for the capacitance sensor; and updating the baseline capacitance value in real-time. |
