Abstract

Virtual keypads are provided which determine an intended user key entry based upon location of keystrokes as well as other keystroke characteristics such as keystroke shape and / or pressure. Virtual keypad layouts which include overlapping or multi-character keys may be used to reduce typing errors on small pressure sensing touch screens. Keystrokes on overlapping or multi-character keys may be disambiguated using measured pressures applied to the pressure sensing touch screen as well as other keystroke characteristics such as keystroke shape. Additional user interfaces are provided which exploit pressure sensing touch screen capable of discriminating magnitudes of pressure exerted upon the touch screen surface.

Description

Technical field [0001] The present invention relates generally to computer user input devices, and more particularly, to pressure sensitive mobile device user interfaces. Background technique [0002] There is an increasing demand for powerful, portable, compact and full-featured computing devices. This trend is particularly evident in the evolution of mobile electronic devices (mobile devices) such as cellular phones, which now act as cell phones, video and audio capture devices, video and audio players, network access terminals, and computers . [0003] As the complexity of mobile devices grows, so does the variety and complexity of application software, making mobile devices a multifunctional productivity tool. However, the usefulness of mobile devices and their applications are limited by the small area available for user interfaces. A conventional cellular phone includes, for example, a simple keypad in a fixed configuration. Recently, mobile devices have released feature-...
