Abstract:
Movement of a point of contact by a user of a touch-sensitive display is determined. In response to the movement, a list of items on the touch-sensitive display is scrolled through. The scroll through is accelerated in response to an accelerated movement of the point of contact. The scroll through and acceleration of the scroll through may be in accordance with a simulation of a physical device having friction.
Abstract:
Movement of a point of contact by a user over an index on a touch-sensitive display is determined. The displayed index has a sequence of index items. Tn response to the movement, a list of information items on the touch-sensitive display is scrolled. The list of information items may include a sequence of information item subsets corresponding to the sequence of index items. The scrolling may include scrolling through a respective information item subset if the point of contact moves over a corresponding respective index item.
Abstract:
A portable communication device with multi-touch input detects one or more multi-touch contacts and motions and performs one or more operations on an object based on the one or more multi-touch contacts and/or motions. The object has a resolution that is less than a pre-determined threshold when the operation is performed on the object, and the object has a resolution that is greater than the pre -determined threshold at other times.
Abstract:
?n indication of interaction with a touch-sensitive display is provided. A soft key is displayed on the touch-sensitive display. Contact with the touch-sensitive display corresponding to interaction with the soft key is detected. The periphery of the soft key smoothly changes in optical intensity in response to detecting the contact.
Abstract:
A portable electronic device displays a plurality of icons (e.g., graphical objects) in a region in a touch-sensitive display; detects a predefined user action, with respect to the touch-sensitive display, for initiating a predefined user interface reconfiguration process; and varies positions of one or more icons in the plurality of icons in response to detecting the predefined user action. The varying includes varying the positions of the one or more icons about respective average positions.
Abstract:
A device with a touch-sensitive display may be unlocked via gestures performed on the touch-sensitive display. The device is unlocked if contact with the display-corresponds to a prededfined gesture for unlocking the device. The device displays one or more unlock images with respect to which the predefined gesture is to be performed in order to unlock the device. The performance of the predefined gesture with respect to the unlock image may include moving the unlock image to a predefined location and/or moving the unlock image along a predefined path. The device may also display visual cues of the predefined gesture on the touch screen to remind a user of the gestures.

Abstract:
A portable electronic device for instant messaging is disclosed. One aspe ct of the invention involves a graphical user interface (GUI) on a portable electronic device with a touch screen display. The GUI has a set of messages exchanged between a user of the device and another person. The set of messa ges are displayed in a chronological order. In response to detecting a scrol ling gesture comprising a substantially vertical movement of a user contact with the touch screen display, the display of messages are scrolled in accor dance with a direction of the scrolling gesture. The detecting of the scroll ing gesture is substantially independent of a horizontal position of the use r contact with the touch screen display.
