Computing platform for loading resources both synchronously and asynchronously

Abstract: A platform that provides the ability for a developer to specify different synchronicity properties for navigations within the same application is disclosed. This includes the ability to specify synchronicity globally for the entire application, to specify different synchronicities on different navigation windows within the application, and on different frames within the same navigation window. It also includes the ability to override the synchronicity of a navigation window or frame for a specific hyperlink or navigation without changing the property for other navigations within the same navigation window or frame. Two classes of navigation objects (navigation window and frame) and computer-implemented methods for retrieving and rendering data are disclosed. The navigation objects include a synchronicity attribute that dictates whether the object will render data synchronously (i.e., at one time after the data has been retrieved) or asynchronously (i.e., substantially as the data is received by the client computer and navigation object).

Local navigation alternatives

Abstract: A vehicle navigation system calculates a route from a start point to a destination further determines alternative routes within a detour region. If the user of the navigation system has left the calculated route the navigation system suggests alternative routes for returning the vehicle to the suggested route within the detour region.

Communication navigation system

Abstract: A communication navigation system, wherein a navigation apparatus requests a recommended route guidance data to a information center and guides a user of the navigation apparatus to a destination by using the recommended route guidance data received from the information center. In this present invention, the navigation apparatus transmits version data of road data held in the navigation apparatus at the request to the information center. The information center prepares a guidance data of recommended route using latest road data held in the information center, and transmits the data to the navigation apparatus. When the information center transmits the guidance data, the information center selects the type of data of the road links along the recommended route, in the guidance data, by comparing the version data received from the navigation apparatus and the version data of each road link along the recommended route. If each data of road links along the recommended route is considered to be contained in the road data held in the navigation apparatus, the information center transmits the only data which enable to specify the road link from the road data held in the navigation apparatus. On the hand, if each data of road links is considered not to be contained in the road data held in the navigation apparatus, the information center transmits whole data of the road link. Therefore, the navigation apparatus can generate the route guidance data by extracting road link data, from its own road data, corresponding to the road link specified by transmitted data and by reconstructing road link data using transmitted data.

Indoor inertial waypoint navigation for the blind

Abstract: Indoor navigation technology is needed to support seamless mobility for the visually impaired. This paper describes the construction and evaluation of an inertial dead reckoning navigation system that provides real-time auditory guidance along mapped routes. Inertial dead reckoning is a navigation technique coupling step counting together with heading estimation to compute changes in position at each step. The research described here outlines the development and evaluation of a novel navigation system that utilizes information from the mapped route to limit the problematic error accumulation inherent in traditional dead reckoning approaches. The prototype system consists of a wireless inertial sensor unit, placed at the users' hip, which streams readings to a smartphone processing a navigation algorithm. Pilot human trials were conducted assessing system efficacy by studying route-following performance with blind and sighted subjects using the navigation system with real-time guidance, versus offline verbal directions.

Navigation system for land vehicles that learns and incorporates preferred navigation routes

Abstract: An adaptive navigation system for a land vehicle is provided that incorporates learned segments of preferred routes into adaptive calculated routes. The navigation system preferably includes a global positioning system or other sources of locator system data and a data processor that may be programmed with destination data and current location data. The data storage apparatus is capable of recording current location data as the vehicle travels to a destination. The system automatically develops a database of a plurality of segments of preferred routes where those segments are different from the route normally calculated by the data processor. On future occasions when the navigation system is used, the data processor is able to incorporate segments of preferred routes in an adaptive calculated route determination when the segments are within a predetermined degree of similarity to the calculated route.
