a housing;

a processor provided within the housing;

a force sensor;

a display assembly provided with a portion of the housing to provide a display surface, wherein the display assembly is structured so that at least a portion of the display surface is in contact with or in sufficient proximity to the force sensor;

one or more position sensors provided with or as part of the display assembly to detect a position of an object that makes contact with the display surface, wherein the one or more position sensors signal the position of the object to the processor; and

wherein when the computing device is operational, the force sensor provides an output to the processor that enables the processor to determine whether a given contact exceeds a threshold criteria;

wherein the processor is configured to interpret a selection input from a combination of the detected position from the one or more position sensors and the output of the force sensor.

2. The computing device of claim 1, wherein the processor is configured to generate one or more soft buttons in the portion of the display surface, and wherein the processor is configured to interpret the selection input as a selection of a soft button or icon.

3. The computing device of claim 2, wherein the processor is configured to generate a plurality of soft buttons in the portion of the display surface, and wherein the processor is configured to interpret the selection input as a selection of one of the plurality of soft buttons by determining which of the one or more soft buttons is displayed over an area that coincides or is most proximate to the detected position of the object making the given contact.

4. The computing device of claim 1, wherein the one or more position sensors are capacitive sensors.

5. The computing device of claim 1, wherein the force sensor uses electrical resistance to provide a measurement of an applied force with a given contact.

6. The computing device of claim 1, wherein the display surface moves inward slightly to enable the force sensor to provide the output.

7. The computing device of claim 1, wherein the housing includes a first housing segment and a second housing segment, wherein the first housing segment is slideably coupled to the second housing segment, and wherein the display assembly and the display surface are provided on the first housing segment.

8. The computing device of claim 7, further comprising a keypad, and wherein the keypad is provided on the second housing segment.

9. A computing device comprising:

a housing;

a processor provided within the housing;

a display assembly provided on a portion of the housing to provide a display surface, wherein at least a portion of the display surface is moveable inward into the housing with contact by an object to the display area;

one or more position sensors provided with or as part of the display assembly to detect a position of the object that makes contact with the display surface, wherein the one or more position sensors signal the position of the object to the processor; and

an electrical contact layer provided below at least a portion of the display surface, wherein the electrical contact layer is actuatable with contact or application of force resulting from inward movement of the display surface, and wherein the electrical contact layer is positioned so that, when the computing device is operational, inward movement of the display surface causes one of the one or more electrical contact elements to signal the processor;

wherein the processor is configured to (i) if the object makes sufficient contact with the portion of the display area to actuate the electrical contact layer, interpret a selection input from the detected position of the object; and

(ii) if the object makes contact with the portion of the display surface without sufficient contact to actuate the electrical contact layer, either ignore the object making contact or interpret a non-selection input from the detected position of the object.

10. The computing device of claim 9, wherein the non-selection input corresponds to a trace input.

11. The computing device of claim 9, wherein the electrical contact layer comprises one or more electrical switches that are actuated with inward movement of the display surface.

12. The computing device of claim 11, wherein inward movement of the display surface results in inward movement of the display assembly.

13.
