The invention provides a system and method for recognizing different hand gestures made by touching a touch sensitive surface. The gestures can be made by one finger, two fingers, more than two fingers, one hand and two hands. Multiple users can simultaneously make different gestures. The gestures are used to control computer operations. The system measures an intensity of a signal at each of an mxn array of touch sensitive pads in the touch sensitive surface. From these signal intensities, a number of regions of contiguous pads touched simultaneously by a user is determined. An area of each region is also determined. A particular gesture is selected according to the number of regions and the area of each region.

The invention provides a method and system for adapting a single-user, single-client application for multiple clients operated by multiple users. An instance of an unmodified single-client, single-user application is executed in each of the clients, and the execution of the multiple instances of the application is coordinated by a wrapper application executing in each of the clients. The wrapper application is configured to communicate messages between the clients via a network to facilitate the coordination.

A graphic multi-user interface resolves multi-user conflicts. The interface includes a touch sensitive surface on which items, such as documents and images, can be displayed. The items have an associated state and policy. Touch samples are generated when users touch the touch sensitive surface. Each samples is identified with a particular user generating the of sample. The samples are associated with particular items. Touching items generates events. A decision with respect to a conflict affecting a next state of a particular item is made according to the events, the state and the policy.

A graphical user interface has a display surface that is segmented into multiple regions. A set of unique, non-overlapping locations is associated with each region. A set of actions that can be performed by the graphical user interface is defined. A document to be displayed on the display surface is selected. The document is moved to a particular location, and a particular action of the set of actions is performed on the selected object according to the particular location of the object on the display surface to operate the graphical user interface in one of a plurality of modes for the particular action.

Graphical objects, such as documents and pop-up items, are projected onto a display surface of a touch-sensitive graphical user interface. The pop-up items associated with a particular document are displayed at a distance from the document. The distance is sufficient to prevent occlusion of the associated document when any of the pop-up items are touched. The pop-up items are connected visually with the particular document by transparent, that is, alpha-blended, colored triangles, so that the pop-up items appear to hover above the display surface.

A direct touch-sensitive input device includes a display surface configured to display images on a front of the display surface, and a direct touch-sensitive surface mounted on a back of the display surface. The display surface and the direct touch-sensitive surface are geometrically coincident. The device can also include a touch-sensitive surface mounted on the front of the device.

A method edits an object having a current state. A first level of an input device is activated to indicate an intent to edit the object, and the current state is stored in response to activating the first level. The object is edited to a next state. The next state is rejected by deactivating the first level, and restoring the current state. The next state is accepted by activating the second level of the input device, and replacing the current state with the next state.

摘要:
The invention provides a novel method for interacting with content objects stored in computer devices connected as nodes of a communications network, each node including an input interface and an output interface, the output interface including a display area. A first display area of a first node is partitioned into a first private work area and a first personal work area associated with the first node. A second display area of a second node is partitioned into a set of second personal work areas and a public work area, each second personal work area associated with other nodes and the public work area associated with all of the nodes.A particular content object of the first node in the first private work area is visualized as a content item according to attributes enabled by the visualizing and moved from the first private work area to the first personal work area. In response to the first moving, the content item in the corresponding second personal work area is visualized according to attributes enabled by the first moving. The content item is then moved from the second personal work area to the public personal work area and visualized, in response to the second moving, in the public work area according to attributes enabled by the second moving.
摘要:
A method selects multiple paths between a server and a client in an overlay network where nodes are connected by links. The nodes include the server and the client. Each path includes a set of selected links. First, in each node, Quality of service metrics are measured of each link directly connecting the node to an immediate neighboring node. The metrics are transmitted to the server. In the server, a link correlation matrix based on the metrics and a path correlation matrix based on the link correlation matrix are determined. Then, the multiple paths are selected based only on the metrics, the link correlation matrix, and the path correlation matrix.
