Abstract: Systems and methods provide for a symmetric homomorphic encryption based protocol supporting communication, storage, retrieval, and computation on encrypted data stored off-site. The system may include a private, trusted network which uses aggregators to encrypt raw data that is sent to a third party for storage and processing, including computations that can be performed on the encrypted data. A client on a private or public network may request computations on the encrypted data, and the results may then be sent to the client for decryption or further computations. The third party aids in computation of statistical information and logical queries on the encrypted data, but is not able to decrypt the data on its own. The protocol provides a means for a third party to aid in computations on sensitive data without learning anything about those data values.

Abstract: Described is a new framework that combines the best of both exploratory search and social search: Collaborative exploratory search. This system allows a small group of focused information seekers to search through a collection of information in concert. The system provides exploratory feedback not only based on the individual's search behavior, but on the current, active search behavior of one's fellow search allies. The assumption is that the users who have gotten together to search collaboratively have the same information need, but differing perspectives and insights as to how to best express the queries to meet that need. The collaborative exploratory search system will therefore provide tools and algorithmic support to focus, enhance, and augment searcher activities. Searchers can, by interacting with each other through system-mediated information displays, help each other find all relevant information more efficiently and effectively.

Abstract: Increasingly people want to maintain a persistent personal presence in virtual spaces (usually via avatars). However, while mobile they tend to devote only short bursts of attention to their mobile device, making it difficult to control an avatar. The core contribution of this IP is to use implicitly sensed context from a mobile device to control avatars in a virtual space that does not directly correspond to the user's physical space. This work allows mobile users to have a presence in a virtual space that matches their environmental conditions without forcing them to configure and reconfigure their virtual presence manually.

Abstract: The present invention relates to a device and methods for storing, sorting, sharing and communicating information with a device, which uses a tangible real-world user interface. In an embodiment of the invention, the device is intended to facilitate communication of information through intuitive operations and commands.

Abstract: Plural versions of an authoring/editing tool for fluid text include both a WYSIWYG editor and a content-driven treetable editor for producing narratives and their behavioral control in a fluid text viewing system environment. The tool includes content-driven treetable visualization and layout mechanisms for authoring and/or editing hypertext narratives, electronic mail threads and other tree-oriented applications. Edit operations are disclosed that permit interactive development and modification of treetables.

Abstract: System and method for controlling the presentation of information, such as dynamically displayed text, includes a computer with a display device and one or more sets of electrode plates and capacitive field sensors arranged facing each other on a substantially flat and substantially stationary surface, such as a table top. The method includes forming capacitive fields between the electrodes and sensors by electrically charging the electrode plates. The sensors monitor for gestural movements made by a user's hands within the fields by detecting changes in voltage levels of the fields. In response to detected gestural movements, the computer adjusts the manner in which the information is presented in the display device, such as the display rate, information source, font size and contrast control.

Abstract: A system and method are provided for implementing the transmission of information to users—via peripheral, or background, auditory cues—in response to the physical action of the users in a particular environment, e.g., the workplace. The system combines three known technologies: active badges, distributed systems, and digital audio delivered via portable wireless headphones.

Abstract: A virtual interface is provided which allows a user to navigate through a representation of a physical target area, such as an office, school or home environment. Using the virtual interface, a user can alter the configuration of a system which transmits information to users via peripheral or background auditory cues in response to physical actions of the users in the environments.
