`
`A section of the disclosure of this patent documentand its figures contain

`
`FIELD OF THE INVENTION
`
`[0003]
`
`The present invention gencrally relates to recciving input from a touch-
`
`sensitive input device. This invention moreparticularly relates to adaptive interpretation
`
`of input received from a touch-sensitive input device.
`
`BACKGROUND
`
`[0004]
`
`A variety of input devices may be used to provide position and control
`
`data to programs executing on computers, cell phones, and other processor-equipped
`
`devices. These input devices include mice, trackballs, touchpads, touch screens, touch
`
`panels, and various other devices. While the mouse andtrackball provide distinct control
`
`EX1002 - 13
`EX1002 - 13

`

`

`Attorney Docket No. 51851/835125 (IMM174.C1)
`
`elements for performing positioning and other control actions, the touchpad combines
`
`positioning and control.
`
`[0005]
`
`For example, a conventional mouse includesa ball or optical sensor for
`
`determining changesin position of thc mouse. The mousealso includes one or more
`
`buttons for performing a control function, such as selecting a graphical representation on
`
`ascreen. In these systems, a user’s intent to make a positional change or provide control
`
`input is apparent to the system.
`
`[0006]
`
`In contrast, conventional touchpads combinethe position and control
`
`functionality in a way that often masks the user’s intent to make a positional change to
`
`provide control input. A user movesa finger along a touchpad to reposition a cursor. A
`
`user may also perform gestures to simulate functions of the buttons of a mouse, such as
`
`drag, click, and double-click. In either case, the user’s finger is in contact with the
`
`surface of the touchpad. Changes in position on the touchpad andin the pressure exerted
`
`on the surface of the touchpad must be used to determine the user’s intent. Because of
`
`the varicty of uscrs that may interact with a touchpad andthe varicty of functions that
`
`may be performed, determining the user’s intent based on a gesture on a touchpadis
`
`difficult. Variables affecting the ability of a program to determine whata useris
`
`attempting to do include the following: the physical difference between users; the
`
`different angles at which a user mayplace their finger while using a touchpad; the
`
`variance in pressure between different users and between the same user; the movementof
`
`the finger across the touchpad while simultaneously attempting to perform actions on the
`
`touchpad. U.S. Patent Number 6,414,671 to Gillespie, et a/. describes one conventional
`
`method for recognizing a user’s gesture as a drag gesture.

`
`Thus, a method and system are needed for accurately determining a user’s
`
`intent based on data supplied by a touch-sensitive input device.
`
`SUMMARY
`
`[0008]
`
`An embodimentofthe present invention provides systems and methods
`
`for adaptive interpretation of input received from a touch-sensitive input device by
`
`receiving a pressure signal indicating a pressure from the input device, comparing the
`
`pseudo pressure signal to an adaptive pressure threshold value, and outputting a signalif
`
`the pseudo pressure signal is greater than the adaptive pressure threshold value.
`
`Further details and advantages of embodiments of the present invention are set forth
`
`below.

`
`DETAILED DESCRIPTION
`
`[0014]
`
`Referring now to the drawings in which like numerals indicate like
`
`elements throughout the several figures, Figure 1 illustrates an exemplary environment
`
`for implementation of an cmbodiment of the present invention. The embodiment shown
`
`includes a touch-sensitive device commonly called a touchpad 102. Touchpad 102
`
`senses the position of a conductor, such as a finger, on the surface of the touchpad (102).
`
`The touchpad (102) is further able to provide a position, comprising X and Y parameters,
`
`as well as a pressure, Z parameter, as an output signal. Conventional touchpads are very
`
`accurate in determining and providing the position of the conductor. For example, some
`
`conventional touchpads have resolutions greater than 1000 dpi. However, conventional
`
`touchpadsare less accurate in determining and providing the pressure exerted on the
`
`touchpad. Other embodiments of the present invention may use other touch-sensitive
`
`input devices, such as a touch panel or touch screen.
`
`[0015]
`
`The touchpad 102 shown does not sense an actual pressure. Instead, the
`
`pressure reading from the touchpad 102 is a pscudo pressure. Touchpads work by
`
`utilizing resistance, capacitance, or membrane switches. The touchpad 102 shown in
`
`Figure | utilizes capacitance, however, an embodimentof the present invention may be
`
`implemented in conjunction with any touch-sensitive input device, includingresistive and
`
`membrane-switch touchpads. In other embodiments, actual pressure may be sensed. For
`
`example, in one embodiment, a touch screen with an attached explicit pressure sensoris
`
`utilized.
`
`[0016]
`
`Capacitance-based touchpads are well knownto those skilled in theart,
`
`and therefore, only a basic description of their function is provided herein. A capacitance

`
`touchpad, such as touchpad 102 shownin Figure 1, includes two sets of wires, which are
`
`perpendicular to one another and configured so that a gap is formed between them.
`
`Whena user places a conductor, such as a finger, on the touchpad 102, wires of the two
`
`perpendicular scts are brought together and form a capacitance. The touchpad 102
`
`measures whichof the wires in each of the two sets has the most capacitance to determine
`
`where the conductor is touching the touchpad 102 and, based on this information,
`
`provides the X and Y coordinates of the position of the conductor on the touchpad 102.
`
`[0017]
`
`The touchpad 102 also provides a pseudo pressure, Z. The pseudo
`
`pressure is based on the amountof capacitance resulting from the conductor touching the
`
`touchpad 102. Accordingly, the amount of capacitanceis not a direct measure of
`
`pressure but rather a pseudo pressure.
`
`[0018]
`
`In other words, the pseudo pressure or Z parameter provided by the
`
`touchpad 102 is not a measure ofthe actual vertical displacement by a conductorat a
`
`single point on the touchpad 102, but rather an estimation of the vertical displacement
`
`based on the size of the capacitance change. The pscudo pressure may n
