Method for identifying changes in signal frequencies emitted by a stylus interacting with a digitizer sensor
Реферат: A method for dynamically updating at least one pre-defined value of a parameter used to identify at least one operational mode of an object for user interaction with a digitizer sensor during interaction with the digitizer sensor comprises detecting signal outputs from a plurality of sensing elements of a digitizer sensor during user interaction with the digitizer sensor; characterizing a pattern formed by the signal outputs from the plurality of sensing elements; identifying a pre-defined event associated with an operational mode of the object based on the pattern; determining a value of the parameter from the signal outputs in response to identification of the pre-defined event; and updating the pre-defined value used to identify the operational mode based on the value of the parameter determined from the identified event.
