Abstract: A method for computer estimations based on statistical tree structures involves obtaining a statistical tree structure for reference elements. The statistical tree structure includes leaf nodes segmenting a statistic for a data label according to data features in the reference elements, and intermediate nodes connecting a first node to the leaf nodes. Each of the first node and the intermediate nodes provide a branching based on one of the data features. The method further includes obtaining target data, including values for the data features, and a value for the data label. The method also includes selecting the first node, associated with a first data feature, traversing the statistical tree structure to a leaf node by matching the values of the data features to the branching of the intermediate nodes, and assessing the value for the data label in the target data based on the statistic associated with the leaf node.

Abstract: An apparatus, a method, and a computer program product for gesture recognition. The apparatus classifies a gesture based on a movement of a body part as detected by a primary sensor. The apparatus determine a reliability level of a secondary sensor and obtains corroborating information associated with the movement of the body part using the secondary sensor when the reliability level satisfies a criterion. The apparatus then confirms or negates the classification of the gesture based on the corroborating information. The secondary sensor may be a sensor already known to the apparatus, i.e., the sensor is currently being worn by the user, or it may be a sensor that is worn by a user at a later time. In the latter case, the apparatus detects for the presence of a new sensor, determines the gesture recognition capabilities of the new sensor and integrates the new sensor into the gesture recognition process.

Abstract: Various arrangements for recognizing a gesture are presented. User input may be received that causes a gesture classification context to be applied from a plurality of gesture classification contexts. This gesture classification context may be applied, such as to a gesture analysis engine. After applying the gesture classification context, data indicative of a gesture performed by a user may be received. The gesture may be identified in accordance with the applied gesture classification context.

Abstract: A system, a method, and a computer program product for managing information for an interface device are provided. The system detects for one of a present physical encounter between a user of the interface device and a person, and a non-physical encounter between the user and a person. The system determines if a detected present physical encounter is an initial encounter or a subsequent encounter, and adds content associated with the person to a database of previously encountered persons when the present physical encounter is an initial encounter. When the present physical encounter is a subsequent encounter or a present non-physical encounter is detected, the system determines if the person is known by the user, and presents information to the interface device corresponding to the person when the person is not known by the user.
