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.

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.

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.

Systems and methods for repeat photography and difference extraction that help users take pictures from the same position and camera angle as earlier photos. The system automatically extracts differences between the photos. Camera poses are estimated and then indicators are rendered to show the desired camera angle, which guide the user to the same camera angle for repeat photography. Using 3D rendering techniques, photos are virtually projected onto a 3D model to adjust them and improve the match between the photos, and the difference between the two photos are detected and highlighted. Highlighting the detected differences helps users to notice the differences.

An automated test to tell computers and humans apart is disclosed, comprising displaying on a computer screen an animation comprising of a foreground and a background, one of the foreground comprising a plurality of typographical characters and the other comprising partial obstruction of the typographical characters, and wherein the animation comprises relative motion between the background and foreground. The automated test may comprise displaying on a computer screen an image, and requiring the user to perform operation on the image to resolve an encoded solution. The test may also comprise displaying on a computer screen a video clip, and requiring a user to provide an input corresponding to subject matter presented in the video clip.

Motion and interaction based CAPTCHA

A system that assures a user that two specific devices have exchanged information correctly over an insecure communication channel. In a typical application, the channel would be a wireless network connection and the information would consist of the public keys of the two devices. The exchanged public keys would subsequently be used to secure any further communication between the two devices. The system requires that both devices have an output modality interpretable by a human. One of the devices must have an input modality that can be operated by the user. The input and output modalities can be very simple e.g., they can consist of a button and LEDs. The users would press the button multiple times. On each press, the LEDs on both devices display a color and the user compares the colors and that they are synchronous. A noticeable delay or color difference signifies a security threat.

A system and a method for using ePaper as a light control media in lighting fixtures or other light enhanced applications to modify, dim or color-shift the light used for lighting the space. One system includes a light source, an ePaper reflector with controllable reflectivity for controlling the light reflected from the reflector and/or an ePaper baffle with controllable translucency for controlling the light through the baffle. The light incident on the ePaper media may include light from other sources such as natural light. One method compares desired lighting in a space to characteristics of the light source. Characteristics of the ePaper media are then adjusted to provide the desired amount of light to the objects under illumination. Reflectivity from walls and furniture may be controlled by applying ePaper to their surfaces. The light source and the ePaper media may be controlled simultaneously to control the lighting.

Passive wands, tracked by one or more cameras, are used as user interface devices. The wands are inexpensive, and are a natural way for users to interact with devices such as large displays. Each wand may be used to specify a full 6 degrees of freedom, which can be helpful for manipulation of 3D applications. The wands may also be used to identify 3D world points, which is useful for multi-camera calibration, and for building 3D models of physical spaces. The described methods provide a more precise estimation of wand pose, and can be implemented with a single camera. Also described is a method for estimation wand pose using information available along a one dimensional 'line scan' within the image, which simplifies processing.
