METHODS OF USING TACTILE FORCE SENSING FOR INTUITIVE USER INTERFACE
First Claim
1. A method of operating an input device, said device configured for detecting a location of touch and measuring a force of touch at said location, the method comprising a step of selecting either a first event or a second event as output of said input device based on said location of touch and said level of force of touch being above or below a predetermined threshold.

Abstract
Described are novel methods of user interface for electronic devices using proportional force information. The new user interface is more intuitive, easier to use and requires less finger manipulations. The input device itself is configured for detecting at least one location of touch and measuring a force of touch at this location as in a capacitance sensing tactile pressure array. At least two events defining an output event of the input device are provided for a particular location. Selection of one event or the other is done based on a force of touch being either above or below a predetermined force of touch threshold. More than one force of touch threshold may be provided for one or more locations, along with a corresponding number of events—to further increase the functionality of the input device. The invention may be used in particular with laptop, tablet computers and smartphones.

3. A method of operating an input device, said input device configured for detecting a location of touch and measuring a force of touch at said location, the method comprising:
-
a. providing at least one predetermined force of touch threshold within an operational range of said input device for at least one location of touch; b. providing at least a first event corresponding to force of touch above said force of touch threshold and a second event corresponding to force of touch below said force of touch threshold for said at least one location of touch; c. detecting location of touch and measuring force of touch; and d. selecting either said first event as an output of said input device if said measured force of touch is above said force of touch threshold or said second event as the output of said input device if said force of touch is below said force of touch threshold. - View Dependent Claims (4, 5, 6, 7, 8, 9)
