Abstract: An automated system and method for assessing and rating accessibility are provided. A processor collects raw data corresponding to geographical objects obtained from sensors, the raw data including tagged and non-tagged data; operates on the raw data to extract features and reduce dimensionality of the raw data, thereby generating processed data having extracted features; generates accessibility data from the processed data; uses supervised machine learning techniques to develop models from the processed data; and implements the models and generates accessibility tags based on the extracted features. A database is configured to store geographical data related to the geographical objects and the accessibility tags corresponding to the geographical locations. An API is configured to access the database and provide a user interface for a user device to use an application to display the accessibility data and the accessibility tags on the user device customized to a disability.

Abstract: Systems and methods are disclosed for mapping lanes for use in vehicle navigation. In one implementation, at least one processing device may be programmed to receive navigational information from a first vehicle and a second vehicle that have navigated along a road segment including a lane split feature; receive at least one image associated with the road segment; determine, from the first navigational information, a first actual trajectory of the first vehicle and a second actual trajectory of the second vehicle; determine a divergence between the first actual trajectory and the second actual trajectory; determine, based on analysis of the at least one image, that the divergence between the first actual trajectory and the second actual trajectory is indicative of the lane split feature; and update a vehicle road navigation model to include a first target trajectory and a second target trajectory that branches from the first target trajectory after the lane split feature.

Abstract: Systems and methods are disclosed for enhancing user queries. In one embodiment, a method includes receiving user data from a plurality of users in respective user sessions where the user data for each user includes at least one manufacturer-identified term for a product and at least one user term for the product, associating the user term for the product and the manufacturer-identified term for the product in response to receiving the user term and the manufacturer-identified term within a user session from a threshold number of users, and returning search results based on the associated manufacturer-identified term in response to receiving a search query that includes the user term.

Abstract: A system and method for providing interactive graphical and multi-media connectivity between a plurality of users, especially in the context of shared content. In aspects, the users are placed into common virtual rooms or virtual interactive environments to permit sharing of content and chat between the individuals in a same virtual interactive environment. Participating users can thereby exchange social layer content as an enhanced content layer beyond a common broadcast content they are experiencing together. Other features and associated functions are also described.

Abstract: A system and method for estimating velocity of a mobile station in a wireless communication system using time-frequency signal processing and a geographical database. The geographical database is used for prediction of ray trajectory and ray power to provide an estimate of propagation delay associated with database points.

In aspects, the users are placed into common virtual rooms or virtual interactive environments to permit sharing of content and chat between the individuals in a same virtual interactive environment. A common theme or subject of interest can be a basis for creating one or more virtual interactive environments or virtual rooms that users may be placed into or move between. Other features and associated functions are also described.
