Embodiment Construction

[0042] These techniques are described below in conjunction with an exemplary input device system. While well suited for use with, for example, systems such as computer / electronic devices, server(s), communication devices, and / or database(s), embodiments are not limited to use with any particular type of configuration of electronic device(s) or system or system components. Those skilled in the art will recognize that the disclosed techniques may be used in any application where it is desired to provide enhanced input capabilities.

[0043] Exemplary systems and methods will also be described in conjunction with software (eg, drivers), modules, and associated hardware. However, to avoid unnecessarily obscuring the present invention, the following description omits well-known structures, components, and devices that may be shown in block diagram form, are known, or are otherwise summarized.

[0044] For purposes of illustration, numerous details are given in order to provide a ...

Abstract

The invention discloses a multi-mode touchscreen user interface for a multi-state touchscreen device. A simple exemplary embodiment can leverage the ability of the touchscreen or touchpad device to distinguish between a fingernail and a palm-side fingertip press as binary distinctions. This can be done via long nails or alternatively, by rotating a hand to invert the finger. The binary distinction can be used to perform different functions. For example, a fingertip press could be the functional equivalent of a left-click on a mouse, and a fingernail press could be the equivalent of a right-click. Another example using a simply binary distinction could be that a fingertip press while typing will result in lower case, and fingernail press while typing will result in upper case. Another example, using a binary distinction, would interpret a light touch for right-clicks or upper case characters and a heavy touch for left-clicks or lower case characters.

Description

technical field [0001] One exemplary aspect is directed to input devices. More specifically, exemplary aspects are directed to touch screen user interfaces having multiple modes. Background technique [0002] A touchpad, also known as a trackpad, is an input device that includes a special surface that translates the motion and position of a user's finger into a relative position on, for example, a screen. Touchpads are increasingly found on laptop computers and can also be used as a replacement for a computer mouse when, for example, space is limited. Touchpads vary in size, but are rarely made larger than 40 square centimeters, as their size is generally proportional to the device they are associated with. There may also be touchpads on personal digital assistants (PDAs), portable media players, laptop computers, netbooks, and the like. [0003] In general, touchpads operate based on capacitive sensing and / or conductive sensing. The most common techniques used enable th...
