摘要:
Multiple users participate in a conference while taking maximum advantage of hardware and bandwidth capabilities of each participant. Each user's system makes known to a directory service its hardware sending and receiving capabilities. The directory service makes this information available to other users who may then wish to join a conference with the user. An initiating user sends invitations via the directory service to the remote users. Each user that accepts an invitation transmits its network address to the initiating user, who then establishes a peer-to-peer connection with each of the remote users. Each participant system exchanges information about hardware capabilities and bandwidth, and a conference manager determines a best model for connecting each of the participants. Depending on the hardware and bandwidth capabilities of the participants, the manager chooses from a duplicate streams model, a multicast model, and a host-among-peers model for connecting the participants.

摘要:
A portable electronic device for instant messaging is disclosed. One aspect of the invention involves a graphical user interface (GUI) on a portable electronic device with a touch screen display. The GUI has a set of messages exchanged between a user of the device and another person. The set of messages are displayed in a chronological order. In response to detecting a scrolling gesture comprising a substantially vertical movement of a user contact with the touch screen display, the display of messages are scrolled in accordance with a direction of the scrolling gesture. The detecting of the scrolling gesture is substantially independent of a horizontal position of the user contact with the touch screen display.

A portable electronic device with a touch-sensitive display is disclosed. One aspect of the invention involves a computer-implemented method in which the portable electronic device: displays an application on the touch-sensitive display; 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-sensitive display. Another aspect of the invention involves a computer-implemented method in which the portable electronic device: 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-sensitive display; and performs the first operation upon detecting a second gesture on the touch-sensitive display, wherein the second gesture is different from the first gesture.
摘要:
A computer-implemented method for use in conjunction with a computing device with a touch screen display comprises: detecting one or more finger contacts with the touch screen display, applying one or more heuristics to the one or more finger contacts to determine a command for the device, and processing the command. The one or more heuristics comprise: a heuristic for determining that the one or more finger contacts correspond to a one-dimensional vertical screen scrolling command, a heuristic for determining that the one or more finger contacts correspond to a two-dimensional screen translation command, and a heuristic for determining that the one or more finger contacts correspond to a command to transition from displaying a respective item in a set of items to displaying a next item in the set of items.

In some embodiments, a portable multifunction device with a touch screen display performs a method that includes: displaying a phone call user interface on the touch screen display, wherein the phone call user interface includes: a first informational item associated with an active phone call between a user of the device and a first party, a second informational item associated with a suspended phone call between the user and a second party, and a merge call icon; upon detecting a user selection of the merge call icon, merging the active phone call and the suspended phone call into a conference call between the user, the first party, and the second party, and replacing the phone call user interface with a conference call user interface. The conference call user interface includes: a third informational item associated with the conference call, and a conference call management icon.
摘要:
A computer-implemented method, for use in conjunction with a portable electronic device with a touch screen display, comprises displaying at least a portion of a structured electronic document on the touch screen display, wherein the structured electronic document comprises a plurality of boxes of content, and detecting a first gesture at a location on the displayed portion of the structured electronic document. A first box in the plurality of boxes at the location of the first gesture is determined. The first box on the touch screen display is enlarged and substantially centered.
摘要:
A plurality of icons are displayed on a touch-sensitive display. Two or more subsets of the plurality of icons are arranged in corresponding rows on the touch-sensitive display. A space greater than a pre-determined value is included between adjacent rows. A contact by a user with the touch-sensitive display that corresponds to a respective icon is detected. A symbol corresponding to the respective icon is displayed in the space between a respective row corresponding to the respective icon and a neighboring row while the contact is maintained.
摘要:
A method includes displaying a first tray and a second tray in a display of the portable communications device. The first tray is configured to display one of more characters that were selected by a user using a click wheel. The second tray includes a first plurality of icons that correspond to a set of characters and one or more recommended words. The first tray includes a first region in a graphical user interface and the second tray includes a second region in the graphical user interface. Scrolling through the first plurality of icons and the one or more recommended words occurs in accordance with one or more navigation commands received from a click wheel.
