     TECHNICAL FIELD 
     The disclosed embodiments relate generally to portable electronic devices, and more particularly, to portable electronic devices that perform similar operations in response to different finger gestures. 
     BACKGROUND 
     As portable electronic devices become more compact, and the number of functions performed by a given device increases, it has become a significant challenge to design a user interface that allows users to easily interact with a multifunction device. This challenge is particular significant for handheld portable electronic devices, which have much smaller screens than desktop or laptop computers. 
     One important aspect of measuring a user interface&#39;s user-friendliness is whether the user interface accepts different types of user actions that correspond to the same function. Different users can choose different user actions based on their own preferences or habits. One user can choose different user actions at different times depending on which user action is more convenient than others at a specific moment. 
     But many conventional user interfaces, such as those that include physical pushbuttons, often have no such inflexibility. All users have to interact with the user interfaces in a specific manner to get desired results whether or not the manner is contrary to most users&#39; preferences or habits. When coupled with the time consuming requirement to memorize these specific manners and the difficulty in activating a desired pushbutton, such inflexibility is becoming increasingly frustrating to most users. 
     Accordingly, there is a need for portable electronic devices with more flexible and intuitive user interfaces that perform similar operations in response to different finger gestures. 
     SUMMARY 
     The above deficiencies and other problems associated with known portable devices are reduced or eliminated by the disclosed portable multifunction device. In some embodiments, the portable electronic device has a touch-sensitive display (also known as a “touch screen” or “touch screen display”) with a graphical user interface (GUI), one or more processors, memory and one or more modules, programs or sets of instructions stored in the memory for performing multiple functions. In some embodiments, the user interacts with the GUI primarily through finger contacts and gestures on the touch-sensitive display. Instructions for performing operations may be included in a computer readable storage medium or other computer program product configured for execution by one or more processors. 
     One aspect of the invention involves a computer-implemented method in which a portable electronic device with a touch screen: displays an application on the touch screen; and when the application is in a predefined mode, performs a predefined operation in response to each gesture of a set of multiple distinct gestures on the touch screen. 
     Another aspect of the invention involves a computer-implemented method in which a portable electronic device with a touch screen: displays a first application; when the first application is in a first mode, performs a first operation upon detecting a first gesture on the touch screen display; and performs the first operation upon detecting a second gesture on the touch screen display, wherein the second gesture is different from the first gesture. 
     Another aspect of the invention involves a portable electronic device. The device includes a touch screen display, one or more processors, memory, and one or more programs. The one or more program are stored in the memory and configured to be executed by the one or more processors. The one or more programs include: instructions for displaying an application; and instructions for performing a predefined operation in response to each gesture of a set of multiple distinct gestures on the touch screen display when the application is in a predefined mode. 
     Another aspect of the invention involves a computer-program product that includes a computer readable storage medium and a computer program mechanism (e.g., one or more computer programs) embedded therein. The computer program mechanism includes instructions, which when executed by a portable electronic device with a touch screen display, cause the device to: display an application; and when the application is in a predefined mode, perform a predefined operation in response to each gesture of a set of multiple distinct gestures on the touch screen display. 
     Another aspect of the invention involves a graphical user interface (GUI) on a portable electronic device with a touch screen display. The GUI has an application displayed in a predefined mode and the application performs a predefined operation in response to each gesture of a set of multiple distinct gestures on the touch screen display. 
     Another aspect of the invention involves a portable electronic device with a touch screen display, comprising: means for displaying an application; and means for performing a predefined operation in response to each gesture of a set of multiple distinct gestures on the touch screen display when the application is in a predefined mode. 
     Thus, the invention provides a transparent and intuitive user interface that performs similar operations in response to different finger gestures on a portable electronic device with a touch screen display.

     DESCRIPTION OF EMBODIMENTS 
     Reference will now be made in detail to embodiments, examples of which are illustrated in the accompanying drawings. In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the invention. However, it will be apparent to one of ordinary skill in the art that the invention may be practiced without these specific details. In other instances, well-known methods, procedures, components, circuits, and networks have not been described in detail so as not to unnecessarily obscure aspects of the embodiments. 
     It will also be understood that, although the terms first, second, etc. may be used herein to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another. For example, a first gesture could be termed a second gesture, and, similarly, a second gesture could be termed a first gesture, without departing from the scope of the present invention. 
     The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used in the description of the invention and the appended claims, the singular forms “a”, “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will also be understood that the term “and/or” as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items. It will be further understood that the terms “comprises” and/or “comprising,” when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof. 
     As used herein, the term “if” may be construed to mean “when” or “upon” or “in response to determining” or “in response to detecting,” depending on the context. Similarly, the phrase “if it is determined” or “if [a stated condition or event] is detected” may be construed to mean “upon determining” or “in response to determining” or “upon detecting [the stated condition or event]” or “in response to detecting [the stated condition or event],” depending on the context. 
     Embodiments of a portable electronic device, user interfaces for such devices, and associated processes for using such devices are described. In some embodiments, the device is a portable communications device such as a mobile telephone that also contains other functions, such as PDA and/or music player functions. 
     The user interface may include a physical click wheel in addition to a touch screen or a virtual click wheel displayed on the touch screen. A click wheel is a physical user-interface device that may provide navigation commands based on an angular displacement of the wheel or a point of contact with the wheel by a user of the portable electronic device. A click wheel may also be used to provide a user command corresponding to selection of one or more items, for example, when the user of the portable electronic device presses down on at least a portion of the wheel or the center of the wheel. Alternatively, breaking contact with a click wheel image on a touch screen surface may indicate a user command corresponding to selection. For simplicity, in the discussion that follows, a portable electronic device that includes a touch screen is used as an exemplary embodiment. It should be understood, however, that some of the user interfaces and associated processes may be applied to other devices, such as personal computers and laptop computers, which may include one or more other physical user-interface devices, such as a physical click wheel, a physical keyboard, a mouse and/or a joystick. 
     The device supports a variety of applications, such as one or more of the following: a telephone application, a video conferencing application, an email application, an instant messaging application, a blogging application, a photo management application, a digital camera application, a digital video camera application, a web browsing application, a digital music player application, and/or a digital video player application. 
     The various applications that may be executed on the device may use at least one common physical user-interface device, such as the touch screen. One or more functions of the touch screen as well as corresponding information displayed on the device may be adjusted and/or varied from one application to the next and/or within a respective application. In this way, a common physical architecture (such as the touch screen) of the device may support the variety of applications with user interfaces that are intuitive and transparent. 
     The user interfaces may include one or more soft keyboard embodiments. The soft keyboard embodiments may include standard (QWERTY) and/or non-standard configurations of symbols on the displayed icons of the keyboard, such as those described in U.S. patent application Ser. No. 11/459,606, “Keyboards for Portable Electronic Devices,” filed Jul. 24, 2006, and Ser. No. 11/459,615 “Touch Screen Keyboards for Portable Electronic Devices,” filed Jul. 24, 2006, the contents of which are hereby incorporated by reference. The keyboard embodiments may include a reduced number of icons (or soft keys) relative to the number of keys in existing physical keyboards, such as that for a typewriter. This may make it easier for users to select one or more icons in the keyboard, and thus, one or more corresponding symbols. The keyboard embodiments may be adaptive. For example, displayed icons may be modified in accordance with user actions, such as selecting one or more icons and/or one or more corresponding symbols. One or more applications on the portable electronic device may utilize common and/or different keyboard embodiments. Thus, the keyboard embodiment used may be tailored to at least some of the applications. In some embodiments, one or more keyboard embodiments may be tailored to a respective user. For example, based on a word usage history (lexicography, slang, individual usage) of the respective user. Some of the keyboard embodiments may be adjusted to reduce a probability of a user error when selecting one or more icons, and thus one or more symbols, when using the soft keyboard embodiments. 
     Attention is now directed towards embodiments of the device.  FIG.  1    is a block diagram illustrating a portable electronic device  100  with a touch-sensitive display  112  in accordance with some embodiments.

A quick press of the push button may disengage a lock of the touch screen  112  or begin a process that uses gestures on the touch screen to unlock the device, as described in U.S. patent application Ser. No. 11/322,549, “Unlocking a Device by Performing Gestures on an Unlock Image,” filed Dec. 23, 2005, which is hereby incorporated by reference. A longer press of the push button (e.g.,  206 ) may turn power to the device  100  on or off. The user may be able to customize a functionality of one or more of the buttons. The touch screen  112  is used to implement virtual or soft buttons and one or more soft keyboards. 
     The touch-sensitive touch screen  112  provides an input interface and an output interface between the device and a user. The display controller  156  receives and/or sends electrical signals from/to the touch screen  112 . The touch screen  112  displays visual output to the user. The visual output may include graphics, text, icons, video, and any combination thereof (collectively termed “graphics”). In some embodiments, some or all of the visual output may correspond to user-interface objects, further details of which are described below. 
     A touch screen  112  has a touch-sensitive surface, sensor or set of sensors that accepts input from the user based on haptic and/or tactile contact. The touch screen  112  and the display controller  156  (along with any associated modules and/or sets of instructions in memory  102 ) detect contact (and any movement or breaking of the contact) on the touch screen  112  and converts the detected contact into interaction with user-interface objects (e.g., one or more soft keys, icons, web pages or images) that are displayed on the touch screen. In an exemplary embodiment, a point of contact between a touch screen  112  and the user corresponds to a finger of the user. 
     The touch screen  112  may use LCD (liquid crystal display) technology, or LPD (light emitting polymer display) technology, although other display technologies may be used in other embodiments. The touch screen  112  and the display controller  156  may detect contact and any movement or breaking thereof using any of a plurality of touch sensing technologies now known or later developed, including but not limited to capacitive, resistive, infrared, and surface acoustic wave technologies, as well as other proximity sensor arrays or other elements for determining one or more points of contact with a touch screen  112 . A touch-sensitive display in some embodiments of the touch screen  112  may be analogous to the multi-touch sensitive tablets described in the following U.S. Pat. No. 6,323,846 (Westerman et al.), U.S. Pat. No. 6,570,557 (Westerman et al.), and/or U.S. Pat. No. 6,677,932 (Westerman), and/or U.S. Patent Publication 2002/0015024A1, each of which is hereby incorporated by reference. However, a touch screen  112  displays visual output from the portable electronic device  100 , whereas touch sensitive tablets do not provide visual output. The touch screen  112  may have a resolution in excess of 100 dpi. In an exemplary embodiment, the touch screen in the display system has a resolution of approximately 168 dpi. The user may make contact with the touch screen  112  using any suitable object or appendage, such as a stylus, a finger, and so forth. In some embodiments, the user interface is designed to work primarily with finger-based contacts and gestures, which are much less precise than stylus-based input due to the larger area of contact of a finger on the touch screen. In some embodiments, the device translates the rough finger-based input into a precise pointer/cursor position or command for performing the actions desired by the user. 
     A touch-sensitive display in some embodiments of the touch screen  112  may be as described in the following applications: (1) U.S. patent application Ser. No. 11/381,313, “Multipoint Touch Surface Controller,” filed on May 2, 2006; (2) U.S. patent application Ser.

No. 11/367,749, “Multi-Functional Hand-Held Device,” filed on Mar. 3, 2006. All of these applications are incorporated by reference herein. 
     In some embodiments, in addition to the touch screen, the device  100  may include a touchpad (not shown) for activating or deactivating particular functions. In some embodiments, the touchpad is a touch-sensitive area of the device that, unlike the touch screen, does not display visual output. The touchpad may be a touch-sensitive surface that is separate from the touch screen  112  or an extension of the touch-sensitive surface formed by the touch screen. 
     In some embodiments, the portable electronic device  100  may include a physical or virtual click wheel as an input control device  116 . A user may navigate among and interact with one or more graphical objects (henceforth referred to as icons) displayed in the touch screen  112  by rotating the click wheel or by moving a point of contact with the click wheel (e.g., where the amount of movement of the point of contact is measured by its angular displacement with respect to a center point of the click wheel). The click wheel may also be used to select one or more of the displayed icons. For example, the user may press down on at least a portion of the click wheel or an associated button. User commands and navigation commands provided by the user via the click wheel may be processed by an input controller  160  as well as one or more of the modules and/or sets of instructions in memory  102 . For a virtual click wheel, the click wheel and click wheel controller may be part of the touch screen  112  and the display controller  156 , respectively. For a virtual click wheel, the click wheel may be either an opaque or semitransparent object that appears and disappears on the touch screen display in response to user interaction with the device. In some embodiments, a virtual click wheel is displayed on the touch screen of a portable multifunction device and operated by user contact with the touch screen. 
     The device  100  also includes a power system  162  for powering the various components. The power system  162  may include a power management system, one or more power sources (e.g., battery, alternating current (AC)), a recharging system, a power failure detection circuit, a power converter or inverter, a power status indicator (e.g., a light-emitting diode (LED)) and any other components associated with the generation, management and distribution of power in portable electronic devices. 
     The device  100  may also include one or more optical sensors  164 .  FIG.  1    shows an optical sensor coupled to an optical sensor controller  158  in I/O subsystem  106 . The optical sensor  164  may include charge-coupled device (CCD) or complementary metal-oxide semiconductor (CMOS) phototransistors. The optical sensor  164  receives light from the environment, projected through one or more lens, and converts the light to data representing an image. In conjunction with an imaging module  143  (sometimes called a camera module), the optical sensor  164  may capture still images or video. In some embodiments, an optical sensor is located on the back of the device  100 , opposite the touch screen display  112  on the front of the device, so that the touch screen display may be used as a viewfinder for either still and/or video image acquisition. In some embodiments, an optical sensor is located on the front of the device so that the user&#39;s image may be obtained for videoconferencing while the user views the other video conference participants on the touch screen display. In some embodiments, the position of the optical sensor  164  can be changed by the user (e.g., by rotating the lens and the sensor in the device housing) so that a single optical sensor  164  may be used along with the touch screen display for both video conferencing and still and/or video image acquisition. 
     The device  100  may also include one or more proximity sensors  166 .  FIG.  1    shows a proximity sensor  166  coupled to the peripherals interface  118 . Alternately, the proximity sensor  166  may be coupled to an input controller  160  in the I/O subsystem  106 . The proximity sensor  166  may perform as described in U.S. patent application Ser. No. 11/241,839, “Proximity Detector in Handheld Device,” filed Sep. 30, 2005, and Ser. No. 11/240,788, “Proximity Detector in Handheld Device,” filed Sep. 30, 2005, which are hereby incorporated by reference. In some embodiments, the proximity sensor turns off and disables the touch screen  112  when the multifunction device is placed near the user&#39;s ear (e.g., when the user is making a phone call). In some embodiments, the proximity sensor keeps the screen off when the device is in the user&#39;s pocket, purse, or other dark area to prevent unnecessary battery drainage when the device is a locked state. 
     In some embodiments, the software components stored in memory  102  may include an operating system  126 , a communication module (or set of instructions)  128 , a contact/motion module (or set of instructions)  130 , a graphics module (or set of instructions)  132 , a text input module (or set of instructions)  134 , a Global Positioning System (GPS) module (or set of instructions)  135 , and applications (or set of instructions)  136 . 
     The operating system  126  (e.g., Darwin, RTXC, LINUX, UNIX, OS X, WINDOWS, or an embedded operating system such as VxWorks) includes various software components and/or drivers for controlling and managing general system tasks (e.g., memory management, storage device control, power management, etc.) and facilitates communication between various hardware and software components. 
     The communication module  128  facilitates communication with other devices over one or more external ports  124  and also includes various software components for handling data received by the RF circuitry  108  and/or the external port  124 . The external port  124  (e.g., Universal Serial Bus (USB), FIREWIRE, etc.) is adapted for coupling directly to other devices or indirectly over a network (e.g., the Internet, wireless LAN, etc.). In some embodiments, the external port is a multi-pin (e.g., 30-pin) connector that is the same as, or similar to and/or compatible with the 30-pin connector used on iPod (trademark of Apple Computer, Inc.) devices. 
     The contact/motion module  130  may detect contact with the touch screen  112  (in conjunction with the display controller  156 ) and other touch sensitive devices (e.g., a touchpad or physical click wheel). The contact/motion module  130  includes various software components for performing various operations related to detection of contact, such as determining if contact has occurred, determining if there is movement of the contact and tracking the movement across the touch screen  112 , and determining if the contact has been broken (i.e., if the contact has ceased). Determining movement of the point of contact may include determining speed (magnitude), velocity (magnitude and direction), and/or an acceleration (a change in magnitude and/or direction) of the point of contact. These operations may be applied to single contacts (e.g., one finger contacts) or to multiple simultaneous contacts (e.g., “multitouch”/multiple finger contacts). In some embodiments, the contact/motion module  130  and the display controller  156  also detects contact on a touchpad. In some embodiments, the contact/motion module  130  and the controller  160  detects contact on a click wheel  116 . 
     The graphics module  132  includes various known software components for rendering and displaying graphics on the touch screen  112 , including components for changing the intensity of graphics that are displayed. As used herein, the term “graphics” includes any object that can be displayed to a user, including without limitation text, web pages, icons (such as user-interface objects including soft keys), digital images, videos, animations and the like. 
     The text input module  134 , which may be a component of graphics module  132 , provides soft keyboards for entering text in various applications (e.g., contacts module  137 , email client module  140 , IM module  141 , blogging  142 , browser module  147 , and any other application that needs text input). 
     The GPS module  135  determines the location of the device and provides this information for use in various applications (e.g., to telephone module  138  for use in location-based dialing, to camera module  143  and/or blogger  142  as picture/video metadata, and to applications that provide location-based services such as weather widgets, local yellow page widgets, and map/navigation widgets).  
     The applications  136  may include the following modules (or sets of instructions), or a subset or superset thereof:
         a contacts module  137  (sometimes called an address book or contact list);   a telephone module  138 ;   a video conferencing module  139 ;   an email client module  140 ;   an instant messaging (IM) module  141 ;   a blogging module  142 ;   a camera module  143  for still and/or video images;   an image management module  144 ;   a video player module  145 ;   a music player module  146 ;   a browser module  147 ;   a calendar module  148 ;   widget modules  149 , which may include weather widget  149 - 1 , stocks widget  149 - 2 , calculator widget  149 - 3 , alarm clock widget  149 - 4 , dictionary widget  149 - 5 , and other widgets obtained by the user, as well as user-created widgets  149 - 6 ;   widget creator module  150  for making user-created widgets  149 - 6 ; and/or   search module  151 .       

     Examples of other applications  136  that may be stored in memory  102  include memo pad and other word processing applications, JAVA-enabled applications, encryption, digital rights management, voice recognition, and voice replication. 
     In conjunction with touch screen  112 , display controller  156 , contact module  130 , graphics module  132 , text input module  134 , and camera module  143 , the image management module  144  may be used to arrange, modify or otherwise manipulate, label, delete, present (e.g., in a digital slide show or album), and store still and/or video images. Embodiments of user interfaces and associated processes using image management module  144  are described further below. 
     In conjunction with RF circuitry  108 , touch screen  112 , display system controller  156 , contact module  130 , graphics module  132 , and text input module  134 , the browser module  147  may be used to browse the Internet, including searching, linking to, receiving, and displaying web pages or portions thereof, as well as attachments and other files linked to web pages. Embodiments of user interfaces and associated processes using browser module  147  are described further below. 
     Note that the above identified modules and applications (including the image management module  144  and the browser module  147 ) correspond to a set of instructions for performing one or more functions described above. These modules (i.e., sets of instructions) need not be implemented as separate software programs, procedures or modules, and thus various subsets of these modules may be combined or otherwise re-arranged in various embodiments. In some embodiments, memory  102  may store a subset of the modules and data structures identified above. Furthermore, memory  102  may store additional modules and data structures not described above. 
     In some embodiments, the device  100  is a device where operation of a predefined set of functions on the device is performed exclusively through a touch screen  112  and/or a touchpad. By using a touch screen and/or a touchpad as the primary input/control device for operation of the device  100 , the number of physical input/control devices (such as pushbuttons, dials, and the like) on the device  100  may be reduced. 
     The predefined set of functions that may be performed exclusively through a touch screen and/or a touchpad include navigation between user interfaces. In some embodiments, the touchpad, when touched by the user, navigates the device  100  to a main, home, or root menu from any user interface that may be displayed on the device  100 . In such embodiments, the touchpad may be referred to as a “menu button.” In some other embodiments, the menu button may be a physical push button or other physical input/control device instead of a touchpad. 
       FIG.  2    illustrates a portable electronic device  100  having a touch screen  112  in accordance with some embodiments. The touch screen may display one or more graphics. In this embodiment, as well as others described below, a user may select one or more of the graphics by making contact or touching the graphics, for example, with one or more fingers  202  (not drawn to scale in the figure) or a stylus (not shown 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 contact may include a gesture, such as one or more taps, one or more swipes (e.g., from left to right, or right to left, or back-and-forth in both directions; upward, or downward, or upward and downward) and/or a rolling of a finger (from right to left, left to right, upward and/or downward) that has made contact with the device  100 . In some embodiments, inadvertent contact with a graphic may not select the graphic. For example, a swipe gesture with that sweeps over an application icon may not select the corresponding application when the gesture corresponding to selection is a tap. In other words, the portable electronic device  100  interprets the meaning of a gesture and acts accordingly after considering which application or module is in use at the moment. 
     The device  100  may also include one or more physical buttons, such as “home” or menu button  204 . As described previously, the menu button  204  may be used to navigate to any application  136  in a set of applications that may be executed on the device  100 . Alternatively, in some embodiments, the menu button is implemented as a soft key in a GUI in touch screen  112 . 
     In one embodiment, the device  100  includes a touch screen  112 , a menu button  204 , a push button  206  for powering the device on/off and locking the device, and volume adjustment button(s)  208 . The push button  206  may be 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, the device  100  also may accept verbal input for activation or deactivation of some functions through the microphone  113 . 
     Attention is now directed towards embodiments of user interfaces (“UI”) and associated processes that may be implemented on a portable electronic device  100 . 
       FIG.  3    illustrates an exemplary user interface for unlocking a portable electronic device in accordance with some embodiments. In some embodiments, user interface  300  includes the following elements, or a subset or superset thereof:
         Unlock image  302  that is moved with a finger gesture to unlock the device;   Arrow  304  that provides a visual cue to the unlock gesture;   Channel  306  that provides additional cues to the unlock gesture;   Time  308 ;   Day  310 ;   Date  312 ; and   Wallpaper image  314 .       

     In some embodiments, the device detects contact with the touch-sensitive display (e.g., a user&#39;s finger making contact on or near the unlock image  302 ) while the device is in a user-interface lock state. The device moves the unlock image  302  in accordance with the contact. The device transitions to a user-interface unlock state if the detected contact corresponds to a predefined gesture, such as moving the unlock image across channel  306 . Conversely, the device maintains the user-interface lock state if the detected contact does not correspond to the predefined gesture. As noted above, processes that use gestures on the touch screen to unlock the device are described in U.S. patent application Ser. No. 11/322,549, “Unlocking a Device by Performing Gestures on an Unlock Image,” filed Dec. 23, 2005, which is hereby incorporated by reference. 
       FIG.  4    illustrates an exemplary user interface for a menu of applications on a portable electronic device in accordance with some embodiments. In some embodiments, user interface  400  includes the following elements, or a subset or superset thereof:
         Signal strength indicator  402  for wireless communication;   Time  404 ;   Battery status indicator  406 ;   Tray  408  with icons for frequently used applications, such as:
           Phone  138 ;   Email client  140 , which may include an indicator  410  of the number of unread emails;   Browser  147 ; and   Music player  146 ; and   
           Icons for other applications, such as:
           IM  141 ;   Image management  144 ;   Camera  143 ;   Video player  145 ;   Weather  149 - 1 ;   Stocks  149 - 2 ;   Blog  142 ;   Calendar  148 ;   Calculator  149 - 3 ;   Alarm clock  149 - 4 ;   Dictionary  149 - 5 ; and   User-created widget  149 - 6 .   
               

     In some embodiments, UI  400  displays all of the available applications  136  on one screen so that there is no need to scroll through a list of applications (e.g., via a scroll bar). In some embodiments, as the number of applications increase, the icons corresponding to the applications may decrease in size so that all applications may be displayed on a single screen without scrolling. In some embodiments, having all applications on one screen and a menu button enables a user to access any desired application with at most two inputs, such as activating the menu button  204  and then activating a desired application (e.g., activating the image management module  144  by a finger tap  412  or other finger gesture on the icon corresponding to the application). Activating the desired application leads to another user interface corresponding to the user-selected application. 
       FIG.  5    illustrates an exemplary user interface for viewing photo albums in accordance with some embodiments. In some embodiments, user interface  500  includes the following elements, or a subset or superset thereof:
           402 ,  404 , and  406 , as described above;   Graphics  504 , e.g., thumbnail images of the first picture or a user-selected picture in the corresponding albums;   Album names  506 ;   Selection icons  508  that when activated (e.g., by a finger gesture on the icon) initiates display of the corresponding album (e.g., UI  600 ,  FIG.  6   ); and   Settings icon  510 , that brings up a settings menu when activated by a user gesture (e.g., a tap gesture).       

       FIG.  6    illustrates an exemplary user interface for viewing an album in accordance with some embodiments. In some embodiments, user interface  1000  includes the following elements, or a subset or superset thereof:
           402 ,  404 , and  406 , as described above;   Photo albums icon  602  that when activated (e.g., by a finger gesture on the icon) initiates transfer to the photo albums UI (e.g., UI  500 );   Thumbnail images  606  of images in the corresponding album;   Play icon  608  that when activated (e.g., by a finger gesture on the icon) initiates a slide show of the images in the album;       

     In some embodiments, the user may scroll through the thumbnails  606  using vertically upward/downward gestures  610  on the touch screen. A stationary gesture on a particular thumbnail (e.g., a finger tap  612  on thumbnail  606 - 11 ) initiates transfer of the application to a different mode, i.e., an enlarged display of the corresponding image (e.g., UI  700 ,  FIG.  7   ). 
       FIG.  7    illustrates an exemplary user interface for viewing enlarged images in an album in accordance with some embodiments. In some embodiments, user interface  700  includes the following elements, or a subset or superset thereof:
           402 ,  404 , and  406 , as described above;   Album name icon  702  that when activated (e.g., by a finger gesture on the icon) initiates transfer to the corresponding album UI (e.g., UI  600 );   Image  706 ;   Additional options icon  708  that when activated (e.g., by a finger gesture on the icon) initiates transfer to a UI with additional options for use of image  706 ;   Previous image icon  710  that when activated (e.g., by a finger gesture  722  on the icon) initiates display of the previous image in the album (e.g.,  606 - 10 );   Play icon  712  that when activated (e.g., by a finger gesture on the icon) initiates a slide show of the images in the album; and   Next image icon  714  that when activated (e.g., by a finger gesture  724  on the icon) initiates display of the next image in the album (e.g.,  606 - 12 ).       

     In some embodiments, selecting the previous or next image icon is not the only way of displaying the previous or next image in the album. For example, the user can initiate viewing of the previous image by making a tap gesture  718  on the left side of the image or making a swipe gesture  716  from left to right on the image. The image  706  moves off screen to the right as the previous image moves on screen from the left. Similarly, the user can initiate viewing of the next image by making a tap gesture  720  on the right side of the image or making a swipe gesture  716  from right to left on the image. The image  706  moves off screen to the left as the next image moves on screen from the right. 
     With multiple ways to perform the same task, the portable electronic device enables a user to choose whichever the user prefers, thereby making the photo management simpler and more intuitive. 
       FIGS.  8 A through  8 D  illustrate exemplary user interfaces for a browser in accordance with some embodiments. 
     In some embodiments, user interface  800 A includes the following elements, or a subset or superset thereof:
           402 ,  404 , and  406 , as described above;   Previous page icon  802  that when activated (e.g., by a finger tap on the icon) initiates display of the previous web page;   Web page name  804 ;   Next page icon  806  that when activated (e.g., by a finger tap on the icon) initiates display of the next web page;   URL (Uniform Resource Locator) entry box  808  for inputting URLs of web pages;   Refresh icon  810  that when activated (e.g., by a finger tap on the icon) initiates a refresh of the web page;   Web page  812  or other structured document, which includes one or more blocks  814  of text content and other graphics (e.g., images);   Settings icon  816  that when activated (e.g., by a finger tap on the icon) initiates display of a settings menu for the browser;   Bookmarks icon  818  that when activated (e.g., by a finger tap on the icon) initiates display of a bookmarks list or menu for the browser;   Add bookmark icon  820  that when activated (e.g., by a finger tap on the icon) initiates display of a UI for adding bookmarks; and   New window icon  822  that when activated (e.g., by a finger lap on the icon) initiates display of a UI for adding new windows to the browser (e.g., UI  800 D,  FIG.  8 D ).       

     In some embodiments, in response to a predefined gesture by the user on a block  814  (e.g., a single tap gesture or a double tap gesture), the portable device initiates a predefined mode of the browser application that, e.g., causes the block to be enlarged and centered (or substantially centered) in the web page display. For example, in response to a single tap gesture  823  on block  814 - 5 , block  814 - 5  may be enlarged and centered in the display, as shown in UI  800 B,  FIG.  8 B . 
     In some embodiments, the width of the user-selected block is scaled to fil the touch screen display. In some embodiments, the width of the block is scaled to fill the touch screen display with a predefined amount of padding along the sides of the display. In some embodiments, a zooming animation of the block is displayed during enlargement of the block. Similarly, in response to a single tap gesture  825  on block  814 - 2 , block  814 - 2  may be enlarged with a zooming animation and two-dimensionally scrolled to the center of the display (not shown). 
     In some embodiments, the device analyzes the render tree of the web page  812  to determine the blocks  814  in the web page. In some embodiments, a block  814  corresponds to a render node that is: a replaced inline, a block, an inline block, or an inline table. 
     In some embodiments, in response to the same predefined gesture by the user on a block  814  (e.g., a single tap gesture or a double tap gesture) that is already enlarged and centered, the enlargement and/or centering is substantially or completely reversed. As shown in the UI  800 B ( FIG.  8 B ), in response to a single tap gesture  829  on block  814 - 5 , the web page image may zoom out and return to UI  800 A,  FIG.  8 A . 
     In some embodiments, in response to a predefined gesture (e.g., a single tap gesture or a double tap gesture) by the user on a block  814  that is already enlarged but not centered, the block is centered (or substantially centered) in the web page display. For example, in response to a single tap gesture  827  on block  814 - 4 , block  814 - 4  may be centered (or substantially centered) in the web page display. Similarly, in response to a single tap gesture  835  on block  814 - 6 , block  814 - 6  may be centered (or substantially centered) in the web page display. Thus, for a web page display that is already enlarged, in response to a predefined gesture, the device may display in an intuitive manner a series of blocks that the user wants to view. This same gesture may initiate different actions in different contexts (e.g., (1) zooming and/or enlarging a block in combination with scrolling when the block is displayed in reduced size, and (2) reversing the enlargement and/or centering if the block is already centered and enlarged). 
     In some embodiments, in response to a substantially vertical upward (or downward) swipe gesture  828  by the user, the web page (or, more generally, an electronic document) may scroll one-dimensionally upward (or downward) in the vertical direction. 
     In some embodiments, in response to a multi-touch  841  and  843  rotation gesture by the user, the web page may be rotated from portrait viewing (UI  800 B,  FIG.  8 B ) to landscape viewing (UT  800 C,  FIG.  8 C ), even if the amount of rotation in the multi-touch  841  and  843  rotation gesture is substantially different from 90°. Similarly, in response to a multi-touch  845  and  847  rotation gesture by the user, the web page may be rotated back from landscape viewing to portrait viewing, even if the amount of rotation in the multi-touch  845  and  847  rotation gesture is substantially different from 90°. 
     In some embodiments, multi-touch  841  and  843  rotation is performed by a user performing two substantially simultaneous finger contact rotations on or near the touch screen  112  within the display area occupied by the web page (e.g., on block  814 - 5 ). 
     Thus, in response to imprecise gestures by the user, precise movements of graphics occur. The device behaves in the manner desired by the user despite inaccurate input by the user. Note that the gestures described above for UI  800 B, which has a portrait view, are also applicable to UIs with a landscape view (e.g., UI  800 C) so that the user can choose whichever view the user prefers for web browsing. 
       FIG.  8 D  depicts a UI  800 D for adding new windows to an application, such as the browser  147 . For example, in response to a user finger tap  848  on the New Window icon  822 , UI  800 D displays an application (e.g., the browser  147 ) in a predefined mode, which includes a displayed window (e.g., web page  812 - 2 ) and at least one partially hidden window (e.g., web pages  812 - 1  and  812 - 3  and possibly other web pages that are completely hidden off-screen). UT  800 D also displays an icon for adding windows to the application (e.g., new window or new page icon  836 ). Upon detecting activation of the icon  836  for adding windows, the browser adds a window to the application (e.g., a new window for a new web page  812 ). 
     Upon detecting a gesture on the touch screen display, a displayed window in the application is moved off the display and a hidden window is moved onto the display. For example, in response to detecting a tap gesture  849  on the left side of the screen, the window with web page  812 - 2  moves partially off-screen to the right to occupy the position left by the window with web page  812 - 3 , which may move completely off-screen. Meanwhile, the partially hidden window with web page  812 - 1  moves to the center of the display, and another completely hidden window with a web page (not shown) may move partially onto the display. Alternatively, a left-to-right swipe gesture  851  on the touch screen may achieve the same effect. 
     Conversely, in response to detecting a tap gesture  853  on the right side of the screen, the window with web page  812 - 2  moves partially to the left and pushes the window with web page  812 - 1  off the display. Meanwhile, the partially hidden window with web page  812 - 3  moves to the center of the display, and another completely hidden window with a web page (not shown) may move partially onto the display. Alternatively, a right-to-left swipe gesture  851  may achieve the same effect. 
     In some embodiments, the tap gestures  849  or  853  may or may not be performed on (or within) the corresponding windows  812 - 1  or  812 - 3 . The portable device operates in the same manner mentioned above as long as the tap gestures are within a predefined range from the corresponding windows. 
     In some embodiments, in response to a tap or other predefined gesture on a delete icon  834 , the corresponding window  812  is deleted. In some embodiments, after the user-selected window is deleted from the display, a neighboring window moves in from the left or right to occupy the spot used to be occupied by the deleted window. In some embodiments, in response to a tap or other predefined gesture on Done icon  838 , the window in the center of the display (e.g.,  812 - 2 ) is enlarged to fill the screen. The operations described above in connection with UI  800 D, which has a landscape view, are also applicable to UIs with a landscape view (e.g., UI  800 A) so that the user can choose whichever view the user prefers for web browsing. 
     A comparison between the image management application (e.g., UI  700 ,  FIG.  7   ) and the browser application (e.g., UI  800 D,  FIG.  8 D ) indicates that both applications have the feature of performing the same set of operations in response to different types of user gestures.  FIG.  9    is a generalized flowchart illustrating a process for performing a predefined operation upon detecting multiple types of user gestures on the portable electronic device&#39;s touch screen in accordance with some embodiments. 
     Upon a user selection of an icon in an application UI, the device displays a set of objects associated with the application on its touch screen ( 902 ). Depending on the application, the set of objects may be a set of thumbnail images (UI  600 ,  FIG.  6   ), browsing windows, web page blocks, or the like. 
     Upon detecting a user selection of one of the objects ( 904 ), the device displays a specific, user-selected object (e.g., an enlarged image) on the touch screen ( 906 ) and then starts monitoring user gestures on the touch screen ( 908 ). 
     If the user gesture is a horizontal/vertical finger swipe on the touch screen ( 910 ), a finger tap on an edge of the touch screen ( 912 ), or a finger tap on the previous/next object icon ( 914 ), the device identifies in the set the previous or next object that is chosen by the user ( 916 ) and displays the previous or next object on the touch screen in replacement of the current object on the display ( 918 ,  920 ). 
     The foregoing description, for purpose of explanation, has been described with reference to specific embodiments. However, the illustrative discussions above are not intended to be exhaustive or to limit the invention to the precise forms disclosed. Many modifications and variations are possible in view of the above teachings. The embodiments were chosen and described in order to best explain the principles of the invention and its practical applications, to thereby enable others skilled in the art to best utilize the invention and various embodiments with various modifications as are suited to the particular use contemplated.
