TECHNICAL FIELD
The disclosed embodiments relate generally to portable electronic devices, and more particularly, to email clients on portable communication devices.
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 particularly significant for handheld portable devices, which have much smaller screens than desktop or laptop computers. This situation is unfortunate because the user interface is the gateway through which users receive not only content but also responses to user actions or behaviors, including user attempts to access a device's features, tools, and functions. Some portable communication devices (e.g., mobile telephones, sometimes called mobile phones, cell phones, cellular telephones, and the like) have resorted to adding more pushbuttons, increasing the density of push buttons, overloading the functions of pushbuttons, or using complex menu systems to allow a user to access, store and manipulate data. These conventional user interfaces often result in complicated key sequences and menu hierarchies that must be memorized by the user.
Many conventional user interfaces, such as those that include physical pushbuttons, are also inflexible. This may prevent a user interface from being configured and/or adapted by either an application running on the portable device or by users. When coupled with the time consuming requirement to memorize multiple key sequences and menu hierarchies, and the difficulty in activating a desired pushbutton, such inflexibility is frustrating to most users.
In particular, many conventional user interfaces for displaying, organizing, managing, and creating emails on a portable communication device are inflexible. The combination of small screens for displaying emails and email lists, complicated pushbutton key sequences, and complex menu hierarchies results in email user interfaces that are not user-friendly. As a result, using an email client on a portable communication device can be frustrating.
Accordingly, there is a need for portable multifunction devices with more transparent and intuitive user interfaces for displaying, organizing, managing, and creating emails that are easy to use, configure, and/or adapt.
SUMMARY
The above deficiencies and other problems associated with user interfaces for portable devices are reduced or eliminated by the disclosed portable multifunction device. In some embodiments, the device has a touch-sensitive display (also known as a “touch screen”) 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. In some embodiments, in addition to emailing, the functions may include telephoning, video conferencing, instant messaging, blogging, digital photographing, digital videoing, web browsing, digital music playing, and/or digital video playing. Instructions for performing these functions may be included in a computer readable storage medium or other computer program product configured for execution by one or more processors.
In accordance with some embodiments of the present invention, a computer-implemented method for displaying electronic messages and lists of electronics messages at a portable communications device with a touch screen display is disclosed. A first portion of a list of entries with information about corresponding electronic messages is displayed in a first area of the touch screen display. A first portion of an electronic message that corresponds to an entry in the list of entries is displayed in a second area of the touch screen display that is separate from the first area. In response to a first gesture by a user in the first area of the touch screen display, the list of entries is scrolled to display a second portion of the list of entries. In response to a second gesture by the user in the second area of the touch screen display, the electronic message is moved in two dimensions to display a second portion of the electronic message.

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 present invention. However, it will be apparent to one of ordinary skill in the art that the present 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.
Embodiments of a portable multifunction 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 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 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 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 multifunction 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.
In some embodiments, in addition to the email application, the device supports a variety of applications, such as one or more of the following: a telephone application, a video conferencing 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 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 multifunction device 100 with a touch-sensitive display 112 in accordance with some embodiments. The touch-sensitive display 112 is sometimes called a “touch screen” for convenience. The device 100 may include a memory 102 (which may include one or more computer readable storage mediums), a memory controller 122, one or more processing units (CPU's) 120, a peripherals interface 118, RF circuitry 108, audio circuitry 110, a speaker 111, a microphone 113, an input/output (I/O) subsystem 106, other input or control devices 116, and an external port 124. The device 100 may include one or more optical sensors 164. These components may communicate over one or more communication buses or signal lines 103.
It should be appreciated that the device 100 is only one example of a portable multifunction device 100, and that the device 100 may have more or fewer components than shown, may combine two or more components, or a may have a different configuration or arrangement of the components. The various components shown in FIG. 1 may be implemented in hardware, software or a combination of both hardware and software, including one or more signal processing and/or application specific integrated circuits.
Memory 102 may include high-speed random access memory and may also include non-volatile memory, such as one or more magnetic disk storage devices, flash memory devices, or other non-volatile solid-state memory devices. Access to memory 102 by other components of the device 100, such as the CPU 120 and the peripherals interface 118, may be controlled by the memory controller 122.
The peripherals interface 118 couples the input and output peripherals of the device to the CPU 120 and memory 102. The one or more processors 120 run or execute various software programs and/or sets of instructions stored in memory 102 to perform various functions for the device 100 and to process data.
In some embodiments, the peripherals interface 118, the CPU 120, and the memory controller 122 may be implemented on a single chip, such as a chip 104. In some other embodiments, they may be implemented on separate chips.
The RF (radio frequency) circuitry 108 receives and sends RF signals, also called electromagnetic signals. The RF circuitry 108 converts electrical signals to/from electromagnetic signals and communicates with communications networks and other communications devices via the electromagnetic signals. The RF circuitry 108 may include well-known circuitry for performing these functions, including but not limited to an antenna system, an RF transceiver, one or more amplifiers, a tuner, one or more oscillators, a digital signal processor, a CODEC chipset, a subscriber identity module (SIM) card, memory, and so forth. The RF circuitry 108 may communicate with networks, such as the Internet, also referred to as the World Wide Web (WWW), an intranet and/or a wireless network, such as a cellular telephone network, a wireless local area network (LAN) and/or a metropolitan area network (MAN), and other devices by wireless communication. The wireless communication may use any of a plurality of communications standards, protocols and technologies, including but not limited to Global System for Mobile Communications (GSM), Enhanced Data GSM Environment (EDGE), wideband code division multiple access (W-CDMA), code division multiple access (CDMA), time division multiple access (TDMA), Bluetooth, Wireless Fidelity (Wi-Fi) (e.g., IEEE 802.11a, IEEE 802.11b, IEEE 802.11g and/or IEEE 802.11n), voice over Internet Protocol (VoIP), Wi-MAX, a protocol for email, instant messaging, and/or Short Message Service (SMS)), or any other suitable communication protocol, including communication protocols not yet developed as of the filing date of this document.
The audio circuitry 110, the speaker 111, and the microphone 113 provide an audio interface between a user and the device 100. The audio circuitry 110 receives audio data from the peripherals interface 118, converts the audio data to an electrical signal, and transmits the electrical signal to the speaker 111. The speaker 111 converts the electrical signal to human-audible sound waves. The audio circuitry 110 also receives electrical signals converted by the microphone 113 from sound waves. The audio circuitry 110 converts the electrical signal to audio data and transmits the audio data to the peripherals interface 118 for processing. Audio data may be retrieved from and/or transmitted to memory 102 and/or the RF circuitry 108 by the peripherals interface 118. In some embodiments, the audio circuitry 110 also includes a headset jack (not shown). The headset jack provides an interface between the audio circuitry 110 and removable audio input/output peripherals, such as output-only headphones or a headset with both output (e.g., a headphone for one or both ears) and input (e.g., a microphone).
The I/O subsystem 106 couples input/output peripherals on the device 100, such as the touch screen 112 and other input/control devices 116, to the peripherals interface 118. The I/O subsystem 106 may include a display controller 156 and one or more input controllers 160 for other input or control devices. The one or more input controllers 160 receive/send electrical signals from/to other input or control devices 116. The other input/control devices 116 may include physical buttons (e.g., push buttons, rocker buttons, etc.), dials, slider switches, joysticks, click wheels, and so forth. In some alternate embodiments, input controller(s) 160 may be coupled to any (or none) of the following: a keyboard, infrared port, USB port, and a pointer device such as a mouse. The one or more buttons (e.g., 208, FIG. 2) may include an up/down button for volume control of the speaker 111 and/or the microphone 113. The one or more buttons may include a push button (e.g., 206, FIG. 2). 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. patents: 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 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. 10/840,862, “Multipoint Touchscreen,” filed on May 6, 2004; (3) U.S. patent application Ser. No. 10/903,964, “Gestures For Touch Sensitive Input Devices,” filed on Jul. 30, 2004; (4) U.S. patent application Ser.

No. 11/228,758, “Virtual Input Device Placement On A Touch Screen User Interface,” filed on Sep. 16, 2005; (7) U.S. patent application Ser. No. 11/228,700, “Operation Of A Computer With A Touch Screen Interface,” filed on Sep. 16, 2005; (8) U.S. patent application Ser. No. 11/228,737, “Activating Virtual Keys Of A Touch-Screen Virtual Keyboard,” filed on Sep. 16, 2005; and (9) 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 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 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 (also 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'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'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'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.

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 push buttons, 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 multifunction 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). 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 (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 the device 100. In some embodiments, inadvertent contact with a graphic may not select the graphic. For example, a swipe gesture that sweeps over an application icon may not select the corresponding application when the gesture corresponding to selection is a tap.
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 multifunction device 100.

        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'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.

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 the desired application (e.g., by a tap or other finger gesture on the icon corresponding to the application).
In some embodiments, UI 400 provides integrated access to both widget-based applications and non-widget-based applications. In some embodiments, all of the widgets, whether user-created or not, are displayed in UI 400. In other embodiments, activating the icon for user-created widget 149-6 may lead to another UI (not shown) that contains the user-created widgets or icons corresponding to the user-created widgets.
In some embodiments, a user may rearrange the icons in UI 400, e.g., using processes described in U.S. patent application Ser. No. 11/459,602, “Portable Electronic Device With Interface Reconfiguration Mode,” filed Jul. 24, 2006, which is hereby incorporated by reference. For example, a user may move application icons in and out of tray 408 using finger gestures.
In some embodiments, UI 400 includes a gauge (not shown) that displays an updated account usage metric for an account associated with usage of the device (e.g., a cellular phone account), as described in U.S. patent application Ser. No. 11/322,552, “Account Information Display For Portable Communication Device,” filed Dec. 23, 2005, which is hereby incorporated by reference.

        a set of mailboxes, such as inbox 3302, which may be organized in rows with a selection icon 3306 for each row, and which may include indicator(s) 3304 of the number of unread emails for a given mailbox;
        a settings icon 3308 that when activated (e.g., by a finger tap on the icon) initiates display of a UI to input mailbox settings (e.g. UI 3600, FIG. 8); and
        a create email icon 3310 that when activated (e.g., by a finger tap on the icon) initiates display of a UI for creating a new email message (e.g. UI 3400, FIG. 6).
    
    


If the set of mailboxes fills more than the screen area, the user may scroll through the mailboxes using vertically upward and/or vertically downward gestures 3312 on the touch screen.
FIGS. 6A-6E illustrate exemplary user interfaces for creating emails in accordance with some embodiments.
In response to the user activating create email icon 3310 (FIG. 5), the device displays UI 3400A. In some embodiments, if the user makes a tap or other predefined gesture on the subject line 3408 or in the body of the email 3412 (FIG. 6A), a letter keyboard 616 appears and the user may input the subject and/or body text (FIG. 6B).
In some embodiments, to enter the email address, the user makes a tap or other predefined gesture on the To: line 3406 of the email; the user's contact list appears (FIG. 6E); the user makes a tap or other predefined gesture on the desired recipient/contact; and the device places the corresponding email address in the email message (FIG. 6B). In some embodiments, contact list user interface 3400E includes the following elements, or a subset or superset thereof:

    
    
        402, 404, 406, as described above;
        Groups icon 802 that when activated (e.g., by a finger tap on the icon) initiates display of groups of contacts;
        First name icon 804 that when activated (e.g., by a finger tap on the icon) initiates an alphabetical display of the user's contacts by their first names (not shown);

In some embodiments, the user may also enter the email address using one or more keyboards (e.g., 616 (FIG. 6B) and 624 (FIG. 6C)). Keyboard 624 is displayed in response to activation of selector icon 618 (e.g., by a finger tap on the icon); subsequent activation of selector icon 626 initiates display of keyboard 616 again. Activation of shift key 628 in UI 3400C (FIG. 6C) initiates display of other keyboards (not shown). The device sends the email message in response to the user activating the send icon 3404 (FIG. 6B) (e.g., by a finger tap on the icon). Alternatively, if the user activates the cancel icon 3402, the device may display a save draft icon (e.g., 1810, FIG. 6D) and a don't save icon (e.g., 1812, FIG. 6D). The device saves the draft if the user activates the save draft icon 1810, e.g., in a drafts folder 3311 (FIG. 5) in email client 140. The device deletes the draft if the user activates the don't save icon 1812 (FIG. 6D).
In some embodiments, in response to the user activating the attach icon 3410 (e.g., by a finger tap on the icon), the touch screen displays a UI for adding attachments (not shown).

        Forward icon 3548 (FIG. 7F) that when activated (e.g., by a finger tap on the icon) initiates creation of an email to be forwarded;
    
    


If the set of emails fills more than the screen area (or more than the screen area above the preview pane 3528), the user may scroll through the emails using vertically upward and/or vertically downward gestures 3514 on the touch screen. Scrolling through the emails is further described below with regards to process 5000 (FIG. 11A).
As shown in FIG. 7B, if the preview pane is sufficiently large, it may show an initial portion of the selected email message, from the body of the email message. In some embodiments, the displayed text from the body of the email message is text that has been extracted by the email client 140 from the HTML version of the selected message. Thus, if the email message body has both plain text and HTML portions, the portion used for generating the preview is the HTML portion. Alternately, instead of displaying a preview pane, in the list of email messages each item (representing a respective email message) may include (in addition to the sender name, date of receipt, subject, etc.) one or more text body lines extracted by the email client 140 from the HTML portion (if any) of the body of the respective email message.
In some embodiments, the email subjects 3508 are not displayed if the preview pane 3528 is used, or, alternately, if the preview pane 3528 occupies more than a predefined portion of the displayed user interface (e.g., UI 3500B). In some embodiments, the position of the preview pane separator 3518 can be adjusted by the user making contact 3516 (FIG. 7A) at or near the preview pane separator 3518 and moving the separator to the desired location by dragging the finger contact 3538 (FIG. 7D). Adjustment of the preview pane separator position is further described below with regards to process 5040 (FIG. 11C). In some embodiments, arrows 3539 (FIG. 7D) or other graphics appear during the positioning of the preview pane separator 3518 (e.g., UI 3500D, FIG. 7D) to help guide the user.
In some embodiments, in response to a tap or other predefined gesture by the user in a row containing information (e.g., 3506, 3510, and/or 3508) about a particular email message, some or all of the text in the row is highlighted (e.g., by coloring, shading, or bolding) and the corresponding message is displayed in the preview pane area 3528, as further described below with regards to process 5020 (FIG. 11B). In some embodiments, in response to a tap or other predefined gesture by the user in a row containing information (e.g., 3506, 3510, and/or 3508) about a particular email message, the email message is displayed on the full screen if the preview pane 3528 is not being used.

In some embodiments, a user may tap anywhere in the row for a particular rule to initiate display of the corresponding rule (e.g., UI 3700B, FIG. 9B).
FIGS. 10A and 10B illustrate an exemplary user interface for moving email messages in accordance with some embodiments.
In response to the user activating move message icon 3522 (FIGS. 7A-7F), the device displays UI 3800A, with some information 3804 for the selected message displayed.
In some embodiments, if the user makes a tap 3802 or other predefined gesture on a row corresponding to a particular mailbox or other folder, the message is moved to the corresponding mailbox or folder (e.g., Work in FIG. 10A). In some embodiments, the selected row is highlighted and an animation appears to move the message information 3804 into the selected row (as illustrated schematically in FIG. 10B).
FIG. 11A is a flow diagram illustrating a process 5000 for displaying emails and email lists in accordance with some embodiments. A first portion of a list of entries with information about corresponding electronic messages is displayed in a first area of a touch screen display on a portable communications device (5002). In some embodiments the list of entries corresponds to a mailbox such as inbox 3302 (FIG. 5). In some embodiments the information includes names 3506 and dates 3510 of email messages and unread message icons 3512, as shown in UI 3500B (FIG. 7B).
A first portion of an electronic message that corresponds to an entry in the list of entries is displayed in a second area of the touch screen display that is separate from the first area (5004). In some embodiments the second area is a preview pane such as preview pane 3528 (FIG. 7B).
In response to a gesture 5006 by a user in the first area of the touch screen display, such as a substantially vertical finger swipe, the list of entries is scrolled to display a second portion of the list of entries (5008). For example, vertically upward and/or vertically downward gestures 3514 scroll the email list displayed in the first area of UI 3500B (FIG. 7B). In some embodiments, the gesture 5006 is detected in any portion of the first area of the touch screen display. In some embodiments, the gesture 5006 has a horizontal position within the first area and its detection is independent of the horizontal position within the first area.
In response to a gesture 5010 by a user in the second area of the touch screen display, such as a two dimensional finger motion, the electronic message is moved in two dimensions to display a second portion of the electronic message (5012). For example, two-dimensional gestures 3532 in preview pane 3528 of UI 3500B scroll the displayed email with vertical and/or horizontal movement (FIG. 7B). In some embodiments, the two dimensional finger motion in the second area of the touch screen display is a diagonal motion and the electronic message is moved diagonally (e.g., in a two-dimensional motion corresponding to the two-dimensional finger motion) in response to the diagonal motion (5014). In some embodiments, the gesture 5010 is detected in any portion of the second area of the touch screen display.
Thus, this process provides for fast vertical scrolling through a list of email messages by finger gestures on the list of email messages, while also providing for two dimensional scrolling within a particular email message by corresponding finger gestures on the particular email message. Two dimensional scrolling permits large email messages (e.g., messages with images or other graphics that will not fit without scaling on the touch screen) to be readily viewed on the touch screen of a portable communications device.
FIG. 11B is a flow diagram illustrating a process 5020 for displaying emails and email lists in accordance with some embodiments. A first portion of a list of entries with information about corresponding electronic messages is displayed in a first area of a touch screen display on a portable communications device (5002), as described above with regards to FIG. 11A. In response to a gesture 5022 by a user on an entry in the list of entries, the first portion of an electronic message that corresponds to the entry is displayed in a second area of the touch screen display that is separate from the first area (5024). In some embodiments, the gesture 5022 is a finger tap in a row containing information about a particular message, such as a row containing information 3506 and 3510 (FIG. 7B). In some embodiments, the gesture 5022 is another predefined gesture. Subsequent steps in process 5020 are described above with regards to FIG. 11A.
FIG. 11C is a flow diagram illustrating a process 5040 for displaying emails and email lists in accordance with some embodiments. Steps 5002-5012 are described above with regards to FIG. 11A. In response to a gesture 5042 by a user on the touch screen display, the size of the first area and the size of the second area are simultaneously adjusted (5044). In some embodiments, the gesture 5042 is a dragging motion on a separator between the first area and the second area, such as separator 3518 (FIG. 7B). The sizes of the first area and the second area are simultaneously adjusted by moving the separator between the first area and the second area (5046). This process permits a user to use a finger gesture to easily adjust the desired size of the list of email messages and desired size of the particular email message being displayed.
FIG. 11D is a flow diagram illustrating a process 5060 for displaying emails and email lists in accordance with some embodiments. A first portion of a list of entries with information about corresponding electronic messages is displayed in a first area of a touch screen display on a portable communications device (5002). A first portion of an electronic message that corresponds to an entry in the list of entries is displayed in a second area of the touch screen display that is separate from the first area (5004). Display of the second area is ended (5062). In some embodiments, display of the second area is ended by dragging a separator such as separator 3518 to decrease the size of the second area until the second area is no longer displayed, as shown in FIG. 7A. In response, increased information is displayed about the electronic messages corresponding to entries in the first area (5064). In some embodiments, message subject information is displayed for each displayed entry (5066). For example, subject information 3508 is displayed for each entry in UI 3500A (FIG. 7A). This process permits a user to use a finger gesture to easily adjust whether a preview pane is displayed.
