Abstract: Improved approaches for assisting a user interacting with a portable wireless communication device are disclosed. The improved approaches can provide a user interface for the portable wireless communication device that includes including a plurality of linked display screens and a plurality of physical keys.

Abstract: Word recommendations are provided in response to text input. For a particular text input, possible word recommendations are identified based on the characters of the input and corresponding neighbor characters on a keyboard layout. The possible word recommendations are scored based on how closely they match the input word on a character-by-character basis, and a subset of the possible word recommendations are selected for presentation to the user.

Abstract: Movement of a user's point of contact with a touch-sensitive display is determined. In response to the movement, a list of information items on the touch-sensitive display is scrolled. The list of information items may include a sequence of information item subsets corresponding to a sequence of index items. While scrolling through respective information subsets, an index symbol is displayed in conjunction with each respective information item subset.

Abstract: A video player for a portable multifunction device is disclosed. In some embodiments, a list of video items is displayed in a portrait orientation of a touch screen display of a portable electronic device. Upon user selection of a respective video item in the list, the user selected video item is automatically displayed in a landscape orientation of the touch screen display.

Abstract: Embodiments of the invention are directed to a system, method, and software for implementing gestures with touch sensitive devices (such as a touch sensitive display) for managing and editing media files on a computing device or system. Specifically, gestural inputs of a human hand over a touch/proximity sensitive device can be used to control, edit, and manipulate files, such as media files including without limitation graphical files, photo files and video files.

Abstract: A portable electronic device, having a touch-sensitive display, displays a plurality of icons on the touch-sensitive display. A contact region when a user makes contact with the touch-sensitive display is detected. Whether the contact region corresponds to one of the plurality of icons is determined in accordance with an electrostatic model.

Abstract: 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.

Abstract: Deletion gestures for use on a portable multifunction device with a touch-sensitive display are disclosed. In some embodiments, a computer-implemented method for use in conjunction with the portable multifunction device comprises displaying a list of items on the touch-sensitive display, detecting a first gesture on the touch-sensitive display to edit the list of items, responding to the first gesture by displaying a first icon next to each deletable item in the list, detecting a second gesture on the touch-sensitive display to select one of the deletable items, and responding to the second gesture by displaying a second icon next to the selected item. If a third gesture on the second icon is detected, the selected deletable item is deleted. If a fourth gesture on the first icon next to the selected deletable item is detected, the second icon is deleted.

Abstract: A user interface method is disclosed. The method can include detecting gestures on or above a multi-event sensor panel and performing an action associated with detected gestures. Such action can include activating or changing a state of one or more GUI objects and emulate functions performed by a mouse or trackball input device.

Abstract: A portable device with a touch screen display detects a contact area of a finger with the touch screen display and then determines a first position associated with the contact area. The cursor position of the finger contact is determined, at least in part, based on: the first position, one or more distances between the first position and one or more of the user interface objects; and one or more activation susceptibility numbers, each associated with a respective user interface object in the plurality of user interface objects. If the cursor position falls into the hidden hit region of a virtual push button on the touch screen display, the portable device is activated to perform operations associated with the virtual push button.

Abstract: Methods and apparatuses for color image restoration and enhancement. In at least one embodiment, color signals for individual channels of an image (e.g., red, green, or blue) are adjusted based on a weighted set of averages (e.g., of the entire image, the center portion, the surrounding portion, or other portions). In one example, pixels with extreme values of color signals (e.g., pure black or white pixels) are ignored for the purposes of restoring color; and, the different averages are weighted according to the pixel location (e.g., the distance from the pixel to a center point). In one example, after color restoration for individual channels, the luminance of each pixel is adjusted back to their original levels; and the range of luminance of the image is further adjusted to provide improved brightness and contrast, where in determining the luminance the red, green and blue color channels are given an equal weight.

Abstract: A method of operating a touch screen to activate one of a plurality of virtual keys is provided. A touch location is determined based on location data pertaining to touch input on the touch screen, wherein the touch input is intended to activate one of the plurality of virtual keys. Each of the plurality of virtual keys has a set of at least one key location corresponding to it. For each of the virtual keys, a parameter (such as physical distance) is determined for that virtual key that relates the touch location and the set of at least one key location corresponding to that virtual key. The determined parameters are processed to determine one of the virtual keys. For example, the determined one virtual key may be the virtual key with a key location (or more than one key location, on average) being closest to the touch location. A signal is generated indicating activation of the determined one of the virtual keys.

Abstract: A portable communication device with multi-touch input detects one or more multi-touch contacts and motions and performs one or more operations on an object based on the one or more multi-touch contacts and/or motions. The object has a resolution that is less than a pre-determined threshold when the operation is performed on the object, and the object has a resolution that is greater than the pre-determined threshold at other times.

Abstract: In some embodiments of the invention, a graphical user interface in an electronic device with a touch screen display and power switch includes one or more user-interface objects to assist a user in powering-off the device while avoiding unintended power-off events due to inadvertent contact with the power switch or the touch screen display.
