Somatosensory feedback wearable object

Abstract: Disclosed are systems, computer-readable mediums, and methods for receiving, from a sensor array, three-dimensional sensory data associated with an environment of a person. The three-dimensional sensory data is converted into a two-dimensional representation. An obstacle is located within the environment based upon the sensory data. The obstacle is mapped onto the two-dimensional representation and the two-dimensional representation is mapped onto a plurality of actuators within a vibrotactile interface. One or more of a plurality of actuators are controlled based upon the mapping of the two-dimensional representation onto the plurality of actuators to provide tactile input to the person that represents a location of the obstacle.

Network Controlled Filtering Over Wireless Device Communications

Abstract: There is stored in a memory an association between each n th one of N content types with a respective n th group of N groups of identifiers (N is an integer greater than one, n indexes from 1 to N, and at least one of the groups has more than one identifier). A beacon sender selects one of the content types for a beacon to be transmitted and selects a beacon identifier from the group associated with the selected content type. The beacon to be transmitted is compiled to include content of the selected content type and the selected beacon identifier. The beacon receiver selects at least one of the content types; and for a plurality of beacons received, filters out from further processing each beacon having a beacon identifier that is not within the group of identifiers associated with any of the at least one selected content types. The network creates the association and broadcasts it in a network cell.

Adaptive position determination

Abstract: A system and method for calculating a position in response to a position request. Observed beacon data associated with the request is used to select a calculation method based on available data for a venue and device capabilities. If sufficient venue data based on previously verified beacon positions is available, a position calculation can resolve floor and venue information. If insufficient previously observed data is available for a venue, the position is calculated using 2D data based on GPS observations. Following the choice a calculation model, the calculation position is returned in response to the position request.

Method for determining and comparing users' paths in a building

Abstract: A system for determining a user's path is described. The system comprises a location server arranged to receive location data of a communication device associated with the user, the location data defining the detected position of the communication device at a number of different points in time, the location server further arranged to receive sequence data associated with the location data indicative of the order in which the location data was determined; path determining means for determining the user's path passing through points defined by the received location data and the associated sequence data; and a comparator for comparing the determined path of the user with one or more predetermined user paths; wherein the location server processes the received location data depending upon the result of the comparison and corrects the determined user path with the processed location data.
