Embodiment Construction

[0020] In general, a method of determining an input at a touch-sensitive input surface of a portable electronic device is described. The method includes: detecting a touch event at the touch-sensitive input surface; sampling touch attributes during the touch event; determining an actual touch location based on the sampled touch attributes during the touch event, and determining a displacement of at least one touch location; and The input is determined based on the actual touch location and a direction of displacement of the touch location.

[0021] Portable electronic devices may include mechanical systems, such as mechanical switches for providing audible and tactile feedback during interaction with a touch-sensitive input surface.

[0022] It should be understood that, for simplicity and clarity of illustration, where appropriate, reference numerals may be repeated among the figures to indicate corresponding or analogous elements. Additionally, numerous specific details are...

Abstract

A method of determining input at a touch-sensitive input surface of a portable electronic device includes detecting a touch event at the touch-sensitive input surface, sampling touch attributes duringthe touch event, determining an actual touch location and determining at least one shift in touch location based on the touch attributes sampled during the touch event, and determining an input basedon the actual touch location and the direction of shift of the touch location.

Description

technical field [0001] The present invention relates generally to electronic devices having touch-sensitive input surfaces and determining user selections at the input surfaces. Background technique [0002] Electronic devices, including portable electronic devices, are in widespread use and can provide a variety of functions including, for example, telephony, electronic messaging, and other personal information manager (PIM) application functions. Portable electronic devices may include many types of devices, including mobile stations such as simple cellular phones, smart phones, wireless PDAs, and laptop computers with wireless 802.11 or Bluetooth capabilities. These devices operate on a variety of networks ranging from data-only networks such as Mobitex and DataTAC to voice- and data-enabled networks such as GSM / GPRS, CDMA, EDGE, UMTS and CDMA2000 networks. [0003] Devices such as PDAs or smart phones are generally intended for handheld use and are easily portable. It ...
