1. A method, comprising:
- detecting a presence of a conductive object on a sensor array at a first position;
detecting a scrolling gesture on the sensor array when the conductive object is moved initially in a first direction from the first position and subsequently in a second direction; and
detecting an end of the scrolling gesture when the conductive object is released from the sensor array.

Abstract
Apparatus and methods for determining a deflection of a moveable conductive plate that is moved over a capacitive sensing device. The method may include moving the moveable conductive plate over sensor elements of the capacitive sensing device, and determining the deflection of the moveable conductive plate. In determining the deflection, a deflection magnitude and a deflection direction may be determined by calculating a vector of x- and y-directions or a vector of a radius and an angle.
