摘要:
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.

A computer implemented method for emulating a mouse with a multi-touch sensitive display surface. Sensing a touching, movement or tapping by one or several fingers or fist emulates mechanical mouse functionality. Sensing a first touching by a first finger at a first location on a multi-touch sensitive display surface and sensing concurrently a second touching by a second finger at a second location on the multi-touch sensitive display surface displays a graphic object on the multi-touch display surface at a position dependent on the first location and the second location to emulate moving a mouse.

摘要:
A computer implemented method for emulating a mouse with a multi-touch sensitive display surface, wherein a touching of the multi-touch sensitive display surface by a user creates a capacitive coupling between the user and the multi-touch sensitive display surface at a location of the touching. The method senses concurrently a first touching by a first finger at a first location on a multi-touch sensitive display surface and a second touching by a second finger at a second location on the multi-touch sensitive display surface, wherein the sensing uses capacitive couplings between the user and the multi-touch sensitive display surface; and displays a graphic object on the multi-touch display surface at a position dependent on the first location and the second location.

A system for delineating partially- or fully-bounded areal regions of a map utilizes deformable templates, which it dynamically expands and contorts to conform to the boundaries of the regions. The system segments the map into a number of cells, with each cell relating, for example, to a pixel. The system then defines an "energy" field for the floor plan by assigning cells corresponding to boundary edges predetermined minimum energy values, cells corresponding to boundary interiors predetermined maximum energy values, and each non-boundary cell an energy value defined by the distance of the cell from the closest boundary edge cell. The system then iteratively manipulates a template over a selected region of the floor plan in an attempt to minimize the "potential" of the template, which is defined by a potential function that includes a "total energy score" and various size and test terms that encourage desired template deformations. The system determines the total energy score, by (i) scan converting the template sides, (ii) weighting the energy values of the cells through which the sides pass based on the lengths of the sides passing through the cells, and (iii) summing the scores. After determining the potential for all possible new locations for each of the vertices, the system selects next locations for each of the vertices and, as necessary, moves the vertices to these next locations to complete an iteration. At various times, the system raises the energy field and updates the template by altering the number of vertices. The system ends its manipulations of the template when it has performed a predetermined number of iterations or, in an energy field at its ceiling values, either the template vertices do not move between iterations or the potential of the template does not change. A user may then edit the template to conform the template more closely to the selected region. A user may also specify certain constraints on template deformation. In response, the system uses a modified potential function for controlling the deformation of the template.

A method summarizes a video acquired of a scene spatially and temporally by specifying a spatial query and a temporal query. Frames of the video are selected according to the spatial query and the temporal query, and then the selected frames are composited into an image that represents spatial and temporal characteristics of the scene.

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.
