Portable Multifunction Device

Figure 1 illustrates a portable multifunction device 100 having a touch screen 120 in accordance with some embodiments. The touch screen optionally displays one or more graphics within user interface 102 (UI). In this embodiment, as well as others described below, a user is enabled to select one or more of the graphics by making a gesture on the graphics, for example, with one or more fingers 104 (not drawn to scale in the figure) or one or more styluses 106 (not drawn to scale in the figure). In some embodiments, selection of one or more graphics occurs when the user breaks contact with the one or more graphics. In some embodiments, the gesture optionally includes one or more taps, one or more swipes (from left to right, right to left, upward and/or downward) and/or a rolling of a finger (from right to left, left to right, upward and/or downward) that has made contact with portable multifunction device 100. In some implementations or circumstances, inadvertent contact with a graphic does not select the graphic. For example, a swipe gesture that sweeps over an application icon optionally does not select the corresponding application when the gesture corresponding to selection is a tap. 

Device 100 optionally also includes one or more physical buttons, such as “home” or menu button 108. As described previously, menu button 108 is, optionally, used to navigate to any application 136 in a set of applications that are, optionally executed on device 100. In some embodiments, the menu button 108 includes a fingerprint sensor that identifies a fingerprint on the menu button 108. The fingerprint sensor is optionally used to determine whether a finger on the menu button 108 has a fingerprint that matches a fingerprint used to unlock the device 100. Alternatively, in some embodiments, the menu button is implemented as a soft key in a GUI displayed on touch screen 120. 

In one embodiment, device 100 includes touch screen 120, menu button 108, push button 110 for powering the device on/off and locking the device, volume adjustment button(s) 120, 114 114, head set jack 116, and docking/charging external port 118. Push button 110 is, optionally, used to turn the power on/off on the device by depressing the button and holding the button in the depressed state for a predefined time interval; to lock the device by depressing the button and releasing the button before the predefined time interval has elapsed; and/or to unlock the device or initiate an unlock process. In an alternative embodiment, device 100 also accepts verbal input for activation or deactivation of some functions through microphone 132. Device 100 also, optionally, includes one or more contact intensity sensors 128 for detecting intensity of contacts on touch screen 120 and/or one or more tactile output generators 130 for generating tactile outputs for a user of device 100.
