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.

Spatial multiplexing to mediate direct-touch input on large displays

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.

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.

A method allocates resources of a wireless communications network to traffic transmitted to user equipment over a channel of the network. A packet of the traffic to be stored in a selected queue is received. A maximum delay of the selected queue is determined, along with a start time, a finish time, and a queuing order. The packet is inserted in the selected queue according to the start time, the finish time and the queuing order, and then a weight of the selected queue is updated. Then, a next packet to be dequeued from the selected queue is scheduled, and the next packet is transmitted to the user equipment over the channel.

A multi-user collaborative graphical user interface has a display area with a horizontal orientation, the display surface is positioned between the multiple users. The display area also has a centroid and a circumference. The display area is partitioned into work areas so that there is one working area for each user of the multiple users. An item is displayed in a particular working area using a global polar coordinate system centered on the centroid.

A method schedules packets in a router of a packet-switched network. The network has a set of service classes including a premium service, an assured service, and a best-effort service. The router includes one queue for each service class. Each queue stores packets to be transmitted according to the associated service class. The method measures an exponential weighted moving average queue length of the queue associated with the premium service each time a packet is stored in that queue. Bandwidth is increased if the average increases over a minimum threshold. The bandwidth remains below an upper limit once the average reaches a maximum threshold.

A method transports a video over a network that includes multiple paths. First, a video is encoded into a base layer, one or more low bit-rate enhancement layers, and one or more high bit-rate enhancement layers using fine-granularity scalability. The base layer and the low bit-rate layers are duplicated into a multiple base layers and multiple low bit-rate enhancement layers, respectively. The high bit-rate layers are partitioned into multiple partial low-bit rate layers, and then each layer is transmitted over a different path of the network to a receiver.

A system and method provides visualization and layout schemes for a circular graphical user interface using global and local polar coordinate systems to display images. The system gives a user of the interface the full capability to relocate, re-orient, scale and layout images in the circular interface. Further, methods are provided to layout images in the Cartesian coordinate system, minimizing overlapping and crowding of images, and supporting users' focus in a group setting for group collaboration around the interface.

A computer network guarantees timeliness to distributed real-time applications by allowing an application to specify its timeliness requirements and by ensuring that a data source can meet the specified requirements. A reflective memory area is established by either a data source of an application. A data source maps onto this reflective memory area and writes data into it. In order to receive data from this data source, an application requests attachment to the reflective memory area to which the data source is mapped and specifies timeliness requirements. The application may specify that it needs data either periodically or upon occurrence of some condition. The application allocates buffers at its local node to receive data. The data source then establishes a data push agent thread at its local node, and a virtual channel over the computer network between the data push agent thread and the application attached to its reflective memory area. The data push agent thread transmits data to the application over the virtual channel according to the timeliness requirements specified by the application. Such a channel-based reflective memory system simplifies data sharing and communication by utilizing the typically unidirectional pattern of data sharing and communication. For example, plant data typically is sent from a plant controller to an operator station, and control data typically is sent from an operator station to a plant controller. Additionally, a single writer, multiple reader model of communication is typically sufficient. That is, all of the data does not need to be transmitted to all of the nodes in a computer network all of the time. Thus, flexibility, switchability and scalability are provided by using channels between reader and writer groups. Scalability is provided by using channels to control data reflection and to represent the unidirectional access pattern. By using an asynchronous transfer mode network, flexibility in channel establishment and cost reduction may be achieved.

In a multi-tasking system a writer task generates real-time and non real-time messages having multiple priority levels in an ascending order arranged in a plurality of priority bands. The real-time messages have predetermined timing deadlines. A plurality of queues indexing the messages by pointers, there is one queue for each priority band. A dispatcher moves pointers from a lower priority queue to a higher priority queue in response to a time-out signal dependent on the timing deadline. A data push agent transmits the messages indexed by the pointers according to the multiple priority levels.
