Electronic device having managed input components
First Claim
1. An electronic device comprising:
- a user interface surface;
a touch-sensitive sensor associated with the user interface surface, the touch-sensitive sensor producing a touch-sensitive signal in response to an actuation of the touch-sensitive sensor at the user interface surface;
a piezoelectric sensor associated with the user interface surface, the piezoelectric sensor producing a piezoelectric signal in response to an actuation of the piezoelectric sensor; and
a processing component coupled to the touch-sensitive sensor and the piezoelectric sensor, the processing component configured to;
determine whether actuation of the touch-sensitive sensor is invalid based on both the touch-sensitive signal and the piezoelectric signal, the determining including comparing an indication of actuation at the user interface surface measured by the touch-sensitive signal with an indication of actuation at the user interface surface measured by the piezoelectric signal, the comparison demonstrating;
that the touch-sensitive signal indicates more user interaction than is indicated by the piezoelectric signal;
orthat the piezoelectric signal indicates more user interaction than is indicated by the touch-sensitive signal; and
perform, or refrain from performing, an operation of the electronic device in response to determining that the actuation of the touch-sensitive sensor is invalid.

Abstract
There is described an electronic device having a touch-sensitive sensor and a piezoelectric sensor, and a method of operating the device. The electronic device detects an actuation of the touch-sensitive sensor, and a touch-sensitive signal is produced by the touch-sensitive sensor in response to detecting the actuation of the touch-sensitive sensor. Also, the electronic device detects an actuation of the piezoelectric sensor, and a piezoelectric signal is produced by the piezoelectric sensor in response to detecting the actuation of the piezoelectric sensor. Next, the electronic device determines whether the actuation of the touch-sensitive sensor is invalid based on the touch-sensitive signal and the piezoelectric signal. The electronic device then performs, or refrains from performing, an operation in response to determining that the actuation of the touch-sensitive sensor is invalid.
