The present invention relates to a system, method, and computer program product for immersive navigation in a virtual environment (VE) suitable for allowing a user to change a view orientation in the VE independently of physical orientation of a user input, such as orientation of the user's head. Specifically, the present invention combines three distinct virtual reality navigation metaphors (trackball navigation, grab navigation, and immersive navigation) into a hybrid navigation approach generating a final virtual-viewpoint that correlates to the characteristics of an intermediate virtual-viewpoint defined by radius, pitch, and heading of a virtual reference sphere (as in trackball navigation), while the final virtual-viewpoint also adjusts the location and gaze direction of the intermediate virtual-viewpoint based on pitch, heading, and roll of the user's head (as in immersive navigation), thus allowing the user to view a point of interest in the VE while simultaneously facing comfortably forward in the physical world.

Method and system for hybrid trackball and immersive navigation in a virtual environment

The present invention relates to a system, method and computer program product for navigating within a virtual environment (VE). More specifically, the present invention relates to navigating large distances in a VE, without becoming disoriented and without becoming cybersick due to exposure to excessive amounts of optical flow. In one embodiment, the present invention combines jumping and flying to allow for quick navigation of large distances, while preserving a sense of orientation and limiting optical flow.

The present invention relates to a system, method and computer program product for enabling user interaction with objects in a virtual environment independently of apparent virtual viewpoint altitude, by non-linearly scaling the virtual actuator. In doing so, the system receives a virtual-viewpoint position and a virtual actuator position from a virtual environment processing subsystem, and a real-viewpoint position and a real-actuator position from a real-world environment tracking subsystem. An xy-scale factor is then calculated based on the virtual-viewpoint position. A non-linear mapping is thereafter calculated between a real dataset and a virtual dataset based on the xy-scale-factor. The real dataset comprises the real-actuator position and the real-viewpoint position in the real-world environment, and the virtual dataset comprises the virtual-actuator position and the virtual-viewpoint position in the virtual environment.

The present invention relates to a general-purpose analogical reasoning system. More specifically, the present invention relates to a high-performance, semantic-based hybrid architecture for analogical reasoning, capable of finding correspondences between a novel situation and a known situation using relational symmetries, object similarities, or a combination of the two. The system is a high-performance symbolic connectionist model which multiplexes activation across a non-temporal dimension and uses controlled activation flow based on an analogical network structure. The system uses incremental inference to stop inference early for object correspondence, uses initial mappings to constrain future mappings, uses inferred mappings to synchronize activation, and independent mapping based on roles, superficial similarity, or composites.

A distributed multimodal collaboration system includes at least one server coupled to a network, a plurality of data sources coupled to the network and a plurality of clients executing on a corresponding plurality of client workstations coupled to the network. The system further includes a tuple-space having a plurality of descriptors. The tuple-space is accessible by the plurality of data sources, and the plurality of clients, and a descriptor distribution and invalidation protocol is operative to distribute and invalidate descriptors accessible by the plurality of clients and the plurality of data sources, and the system includes a transaction processor for committing a plurality of transactions associated with the descriptor distribution and invalidation protocol.

System and method for distributed multimodal collaboration using a tuple-space

A method for transforming a map based on associated geospatial data. A map is segmented into logical segments representing map-based entities. The geospatial data is then associated with the logical segments. The logical segments are scaled based upon the associated data. The logical segments are then repositioned to avoid overlapping other logical segments and a new map display based on the scaled and repositioned logical segments is provided.
