A collaboration system provides enhanced user interface to enable users to interact with electronic devices. In one embodiment, users can add content to a digital system by using a pen that streams coordinates so that input to the digital system may be based on conventional pen and paper handwriting. In another embodiment, a pie-based menu system is used for input to large display area digital devices in which an occluded portion of the pie-based menu system is not used for direct input by the user. The selection of which areas of the pie-based menu system should be omitted from use is adaptive and responsive to whether the user is left-handed or right-handed, and the wrist angle defined by the user's posture. In still another embodiment, an ergonomic open-shaped pie menu system is provided to facilitate selection of options on a digital surface.

The present invention relates to a multi-touch display system that supports both multi-touch human input as well as input from a digital pen. The display system has a display panel that is configured to allow human touches along a front surface to be detected and tracked. The display panel also includes a location pattern that preferably covers the viewable areas of the display panel. The location pattern is configured to allow any location within the location pattern to be detected by analyzing a portion of the display pattern that is associated with the particular location. The digital pen is used to 'write' on the display panel, wherein such a writing function involves detecting the location where writing occurs and controlling display content that is displayed on the display panel to reflect what is being written.

A method for preventing information losses due to network node failure is disclosed. The method comprises the steps of operatively connecting at least one backup node to a primary node, followed by synchronizing the at least one backup node and the primary node. Next, the method comprises receiving, from a first endpoint, ingress traffic in the primary node and replicating the ingress traffic to the at least one backup node. Next, the method outputs, from the primary mode, primary egress traffic and outputs, from the at least one backup node, backup egress traffic. The method then determines if the primary node has failed. Then, the method transmits, to a second endpoint, the primary egress traffic if it is determined that the primary node has not failed, and transmits, to the second endpoint, the backup egress traffic from a selected one of the at least one backup nodes if it is determined that the primary node has failed.

A technique for adaptively distributing a web server request in a system having a plurality of web servers is disclosed. In one embodiment, the technique is realized by first generating a web server request distribution function for each of the plurality of web servers based upon performance measures of each of the plurality of web servers, wherein each of the plurality of web servers is assigned a respective probability range based upon each respective web server request distribution function. A random probability number is then generated for a web server request. The particular probability range encompassing the random probability number is then determined so as to identify the corresponding web server to which the web server request is to be distributed.
