  • Publication number: 20230343035
    Abstract: A navigation system for facilitating navigation in a space includes a network interface configured to access a representation of a space, a memory storing instructions, and at least one processor coupled with the memory. The at least one processor executes the instructions to detect objects in the representation of the space and determine a plurality of desirable positions which facilitate navigation in the representation of the space based on the detected objects.

  • Patent number: 11421993
    Abstract: Aspects and embodiments disclosed herein include a computational approach to automatically generate a wayfinding design for a given environment. To use aspects and embodiments of the disclosed computational approach, a designer specifies all the navigation scenarios likely to be taken by the users. A wayfinding design is then generated to accommodate the needs of all the scenarios while considering a number of desirable factors relevant to the navigation experience and management convenience. Through agent-based simulations, the locations of the wayfinding signs are further refined by considering visibility and robustness with respect to the possible mistakes made by the users throughout their navigation. After generating a wayfinding design, the designer can gain further insights of the design by visualizing the accessibility of a destination from any other locations in the environment and remove any blind zones by adding more signs and re-triggering the optimization.

  • Publication number: 20210404826
    Abstract: Technologies are provided for generation of exertion-aware paths. Some embodiments include a computing system that can generate a path based at least on first data defining a terrain, second data defining a target level of total work, and third data defining a target level of perceived difficulty. The computing system also can generate a road surface along the path. Generating the road includes embedding metadata defining position-dependent resistance forces based on a physics model, the metadata controlling force feedback at virtual-reality equipment. The computing system also can supply the road surface to the virtual-reality equipment.

  • Patent number: 11014003
    Abstract: Balancing an exercise intensity level and a fun factor of a game is non-trivial and challenging. Disclosed herein are aspects and embodiments of an optimization-based approach to address this challenge. The approach can be applied to synthesize a game level with a desired exercise intensity level. By formulating the design problem as an optimization, a level designer can easily balance factors concerning the exercise intensity level of the game as well as other design factors and constraints.

  • Publication number: 20140278274
    Abstract: A method includes receiving one or more learning configurations, each learning configuration related to an acceptable arrangement of items within an environment. The method further includes extracting from the learning configurations representative item information and relationship information, synthesizing a configuration of items for a defined environment based at least in part on the extracted representative item information and relationship information, determining a cost of the synthesized configuration, and, based on the cost of the synthesized configuration, identifying the synthesized configuration as acceptable.
