IONavi: An Indoor-Outdoor Navigation Service via Mobile Crowdsensing

Abstract: The proliferation of mobile computing has prompted navigation to be one of the most attractive and promising applications. Conventional designs of navigation systems mainly focus on either indoor or outdoor navigation. However, people have a strong need for navigation from a large open indoor environment to an outdoor destination in real life. This article presents IONavi, a joint navigation solution, which can enable passengers to easily deploy indoor-outdoor navigation service for subway transportation systems in a crowdsourcing way. Any self-motivated passenger records and shares individual walking traces from a location inside a subway station to an uncertain outdoor destination within a given range, such as one kilometer. IONavi further extracts navigation traces from shared individual traces, each of which is not necessary to be accurate. A subsequent following user achieves indoor-outdoor navigation services by tracking a recommended navigation trace. Extensive experiments are conducted on a subway transportation system. The experimental results indicate that IONavi exhibits outstanding navigation performance from an uncertain location inside a subway station to an outdoor destination. Although IONavi is to enable indoor-outdoor navigation for subway transportation systems, the basic idea can naturally be extended to joint navigation from other open indoor environments to outdoor environments.

On-vehicle navigation system, its information processing method, portable communication terminal used for it and navigation device

Abstract: PROBLEM TO BE SOLVED: To effectively utilize hardware resources by sharing information between a navigation device and a mobile phone. SOLUTION: The mobile phone 110 and the navigation device 120 have a communication I/F 115, 121 capable of communicating with each other. A GPS receiver 111 is provided on the mobile phone and, by using the communication I/F, its position information is transmitted to the navigation device, and the navigation device receives the position information by using the communication I/F. The navigation device produces map information including the present position and information on route to the destination based on the position information and transmits the destination information and the route information to the mobile phone. The mobile phone renews the position information by the GPS receiver at every specific time and transmits the renewed position information to the navigation device. The navigation device receives the renewed position information and renews the route information and transmits the renewed position information to the mobile phone. COPYRIGHT: (C)2007,JPO&INPIT

A low cost outdoor assistive navigation system for blind people

Abstract: With over 39 million visually impaired people worldwide, the need for an assistive device that allows the blind user navigate freely is crucial. We have developed an off-line navigation device that uses 3-D sounds to provide navigation instructions to the user. Our device relays directional information to the user through special Audio Bone headphones, which use bone conduction technology. Sounds are recorded and can therefore be selected by the blind user. Navigation processing is handled by a Raspberry Pi. We are using a magnetic compass and gyroscope to calculate the direction that the user is facing. Route queries of the destination address are geocoded using the Geo-Coder-US module and passed to the MoNav module to generate a pedestrian route. Additional capabilities of the device include speech recognition and voice prompts for obtaining the user's desired destination address. The user can input the address b y speaking into a microphone. The entire system is mounted to a pack that sits on the user's waist. It is very light and portable and it does not impede any of the user's senses while it is being used.

Feel your route: a tactile display for car navigation

Abstract: A car navigation system that displays turn-by-turn instructions using a vibro-tactile waist belt aims to avoid the cognitive load that most car navigation systems place on drivers.

SEND: A Situation-Aware Emergency Navigation Algorithm with Sensor Networks

Abstract: When emergencies happen, navigation services that guide people to exits while keeping them away from emergencies are critical in saving lives. To achieve timely emergency navigation, early and automatic detection of potential dangers, and quick response with safe paths to exits are the core requirements, both of which rely on continuous environment monitoring and reliable data transmission. Wireless sensor networks (WSNs) are a natural choice of the infrastructure to support emergency navigation services, given their relatively easy deployment and affordable costs, and the ability of ubiquitous sensing and communication. Although many efforts have been made to WSN-assisted emergency navigation, almost all existing works neglect to consider the hazard levels of emergencies and the evacuation capabilities of exits. Without considering such aspects, existing navigation approaches may fail to keep people farther away from emergencies of high hazard levels and would probably encounter congestions at exits with lower evacuation capabilities. In this paper, we propose SEND, a situation-aware emergency navigation algorithm, which takes the hazard levels of emergencies and the evacuation capabilities of exits into account and provides the mobile users the safest navigation paths accordingly. We formally model the situation-aware emergency navigation problem and establish a hazard potential field in the network, which is theoretically free of local minima. By guiding users following the descend gradient of the hazard potential field, SEND can thereby achieve guaranteed success of navigation and provide optimal safety. The effectiveness of SEND is validated by both experiments and extensive simulations in 2D and 3D scenarios.
