Abstract: Described are systems and methods for helping a participant, who is represented in a remote space by a remote device, to understand the physical state of the remote device in the remote space. This is done through physical and virtual changes in their local space that reflect their own remote physical representation. For example, if their action in the local space causes the remote telepresence robot to rotate 90 degrees, their local display through which the control the robot might rotate 9 degrees. The described methods will help participants have a greater sense of presence in a remote space.

Abstract: A computer-implemented method performed in a computerized system incorporating a central processing unit, a localization signal receiver and a memory, the computer-implemented method involving: receiving at least one localization signal using the localization signal receiver; measuring a strength of the received localization signal; using the central processing unit to extract a key from the received localization signal; determining a location based at least on the measured strength of the received localization signal; and validating the determined location using the extracted key. The localization signal may be provided by one or more beacons, such as iBeacons, which may be placed at various locations within a building. The key may be randomly generated and periodically transmitted to the beacons to prevent replay attacks. A ticket issued by a near field communication (NFC) device may be used for additional location validation to prevent tunneling and collusion.

Abstract: A method of identifying a location of a mobile device in a building includes identifying non-overlapping regions in a building. A server collects base station signal strength measurements at a plurality of distinct points in the building, with at least one point in each region. The server trains region classifiers for each region. Each region classifier is configured to compute a probability estimate that the test point is inside the region, using inputs that are signal strength differences. The server receives signal strength measurements from the base stations, taken by a mobile device at an unknown point. The server computes differences in signal strengths between pairs of base stations, and applies the region classifiers to the signal strength differences, thereby estimating the region where the mobile device is located. The server then transmits the estimated region to a user.

Abstract: Managing contact groups entails receiving email header information for electronic messages sent during a certain period of time. Each header includes unique identifiers for the sender and each recipient. The set of these unique identifiers from each header forms a de facto group. For each group, the process computes a usage value based on the number of distinct messages corresponding to the group. The process also identifies a set of saved groups, where each saved group is a set of unique identifiers of people, and each saved group has a usage value. The usage value is 0 when the saved group does not equal any de facto group. The process compares the de facto groups and their associated usage values to the saved groups and their associated usage values, and provides a recommendation to modify the set of saved groups based on the comparisons.

Abstract: Exemplary embodiments described herein are directed to systems and methods that estimate a user's affect and communication preferences from presence data. The exemplary embodiments use a small set of features derived from a user's recent high level presence states. Exemplary embodiments also use features from broader classes of presence data. Utilizing features from a combination of presence data and recent presence states may provide improvement over estimates that users are able to make themselves. The exemplary embodiments further consider cost, burden on the user, and privacy issues in estimating affect and communication preferences.

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: Gesture-based methods of managing communications of a user participating in communication sessions permit the user to easily manage the communications sessions by defining gestures, defining a meaning of the gesture, and outputting the meaning of the gesture to a communication session when the gesture is detected. The gestures may be contextually dependent, such that a single gesture may generate different output, and may be unconventional to eliminate confusion during gesturing during the communication sessions, and thereby the communications sessions may be more effectively managed.
