Navigation system, navigation apparatus, and server apparatus

Abstract: The Navigation Apparatus transmits to a server apparatus a current position, a destination, and an area of a geographical information stored in a geographic information memory part. The server apparatus receives them to calculate one or more potential routes from the current position to the destination; sets a potential passing-by point for each potential route in the area of the geographic information stored in the Navigation Apparatus; and transmits those potential passing-by points to the Navigation Apparatus. The Navigation Apparatus receives them to calculate traveling routes from the current position to the potential passing-by points and selects one of the potential passing-by points, thereby deciding the passing-by point as a temporary destination within the area of the geographic information stored in the Navigation Apparatus. In this way, the route navigation can be realized without increasing the memory capacity of the geographic information memory part of the Navigation Apparatus. Additionally, since only necessary information, such as the geographic information, passing-by points and the like, are transmitted and received, the communication cost can be reduced.

Indoor Positioning System Using Beacon Devices for Practical Pedestrian Navigation on Mobile Phone

Abstract: In this paper, we propose a positioning system for indoor pedestrian navigation services using mobile phones. Position information services with a Global Positioning System (GPS) are widely used for car navigation and portable navigation. Their navigation systems facilitate development of industry and increase the convenience of civil life. However, such systems and services are available only for locations in which satellite signals can be received because users' self-positions are computed using GPS. Therefore, we developed a system for indoor environments, operating with a user's mobile terminal and battery-driven beacon devices in a server-less environment. Moreover, to provide convenient services using position information indoors, we developed an indoor navigation system that is useful in commercial facilities and office buildings. The system consists of smart phone and license-free radio beacon devices that can be driven with little electric power. In our proposed method, probabilistic estimation algorithms are applied to estimate self-positions in indoor locations, such as those where it is impossible to receive GPS signals. Feature of the system is that 2.5-dimensional indoor positioning is possible to calculate with low computational power device such as mobile phone. The system works autonomously, i.e., the user's device receives wireless beacon signals from the surrounding environment and can thereby detect a user's position independently from the mobile terminal, thereby obviating server-side computation.

Method and apparatus for automatically optimizing and setting a GPS reception period and map contents

Abstract: A method and apparatus for Global Positioning System (GPS) navigation is configured to automatically set an optimal GPS reception period and optimal map contents according to a moving speed of a user in a navigation system using a GPS terminal. When the moving speed of the user is considered, power efficiency is increased by optimizing a GPS reception period in terms of hardware and system load is decreased by reducing an unnecessary system operation in terms of software. User convenience is maximized by optimizing map contents requested by the user according to a moving speed in real time and displaying the optimized map contents.

Predictive server-side rendering of scenes

Abstract: A server device and method are provided for use in predictive server-side rendering of scenes based on client-side user input. The server device may include a processor and a storage device holding instructions for an application program executable by the processor to receive, at the application program, a current navigation input in a stream of navigation inputs from a client device over a network, calculate a predicted future navigation input based on the current navigation input and a current application state of the application program, render a future scene based on the predicted future navigation input to a rendering surface, and send the rendering surface to the client device over the network.
