19 Mar 1990TL;DR: A backup navigation system that is failure resistant as mentioned in this paper has a multiple member of navigation subsystems, each of which is connected to only one computer processor of each computer, and each navigation output is sent into a control navigation computer.
Abstract: A backup navigation system that is failure resistant. The backup navigationystem has a multiple member of navigation subsystems. The backup navigation system has the same multiple number of computers. Each computer has the same multiple number of computer processors. Each navigation subsystem is connected to only one computer processor of each computer. Each computer selects data from one of its computer processors in preference to data from any other of its computer processors. Each computer provides a navigation output. Each navigation output is sent into a control navigation computer. One of these navigation outputs is selected by the control navigation computer. A navigation output from one of the computers can also be selectively sent into a navigation interface buffer.

TL;DR: In this article, a navigation system produces processing points based on a particular shape and size of the large non-digitized area and determines whether such processing points should be used for route search operations.
Abstract: A navigation system is able to find an optimum route to a destination even when a large non-digitized area exists between a starting point to the destination. The navigation system produces processing points based on a particular shape and size of the large non-digitized area and determines whether such processing points should be used for route search operations. When it is determined that the route search operation is effective, the navigation system performs A* algorithm search operations with respect to the start point, processing points and the destination and detects an optimum route to detour the large non-digitized area.

TL;DR: In this article, a method for ensuring continuity of service of a portable navigation device (10) in the event of insufficient reception of GNSS satellite signals is described, in which the user provides the portable navigation devices (10), with first data relating to the current position of the device through data input means (115), and wherein the personal navigation device, in order to calculate its own position, uses said first data entered by the user and second data coming from localization tools (105,110,127,170,180,190,190) associated with the Portable Navigation Device (10

19 Jun 2003TL;DR: In this paper, the navigation apparatus sequentially compares a present walking speed with another walking speed which was acquired at the same position in the past by executing a walking-speed comparing process operation, and then notifies such an information related to the present walking pace of this user based upon the comparison result with respect to the user.
Abstract: In a navigation apparatus, when a user starts to walk along a walking course, the user instructs the navigation apparatus to commence the navigation operation as to this walk course which has been formed/registered thereinto based upon positional information, walking pattern information, and temporal information. The navigation apparatus sequentially compares a present walking speed with another walking speed which was acquired at the same position in the past by executing a walking-speed comparing process operation, and then notifies such an information related to a present walking pace of this user based upon the comparison result with respect to the user.

TL;DR: A system which based on a specific efficiently collected geographical data generates human-like landmark-enhanced navigation instructions which proved usability and efficiency and set of design recommendations to increase the usability of the system along with specific examples of usage with particular landmarks.
Abstract: Visual impairment limits a person mainly in ability to move freely and independently. Even with many navigation aids and tools currently on the market, almost one third of the visually impaired do not travel independently without a guide, and human-prepared landmark-enhanced itineraries of the route are the most useful. We designed a system which based on a specific efficiently collected geographical data generates human-like landmark-enhanced navigation instructions. The studies we conducted (quantitative n = 16, qualitative n = 6) proved usability and efficiency of the system. Further we provide set of design recommendations to increase the usability of the system along with specific examples of usage with particular landmarks.
