Abstract
Left- and right-click buttons of a virtual touchpad each have two modes, a “click” mode and an “on/off” mode. In “click” mode, touching a finger to the left- or right-click button triggers a mouse button down event while releasing a finger from the button triggers a mouse button up event. In “on/off” mode, the left- and right-click buttons each have two states, “on” and “off.” If the current state of the left- or right-click button is “off,” then touching the button triggers the mouse button down event, while releasing the button changes the state of the button to “on” but does not trigger any mouse events. Conversely, if the current state of the left- or right-click button is “on,” then touching the button does not trigger any mouse events, but releasing the button thereafter changes the state of the button to “off” and triggers the mouse button up event.
