DEVICE AND METHOD FOR EMULATING A TOUCH SCREEN USING FORCE INFORMATION
First Claim
1. An input device for use with a host system of the type which includes a graphical user interface configured to display user selectable items, the input device comprising;
- a touchpad configured to detect input objects in a sensing region of the touchpad; and
a processing system communicatively coupled to the host and to the touchpad, the processing system configured to;
determine positional information and force information for an input object in the sensing region;
control the position of an input object representation on the graphical user interface based on the positional information of the input object;
control the selection of an item based on a force imparted to an input surface of the touchpad by the input object satisfying a first force threshold; and
control the activation of the selected item based on the force imparted to the input surface by the input object satisfying a second force threshold after satisfying the first force threshold.

Abstract
Methods, systems and devices are described for operating an electronic system to emulate a touch sensitive interface using a touchpad and a display screen which does not overlap the touchpad. The method includes determining positional information and force information for an input object in a sensing region of the touchpad; positioning an input object representation on the display screen based on the positional information; selecting a user selectable item on the display screen based on the force information satisfying a first force threshold; and activating the selected item based on the force information satisfying at least one of the first force threshold and a second force threshold.
