TL;DR: When a navigation script has a contradiction with respect to time and place, a navigation information presenting apparatus adjusts the contradiction, executes instructions of the navigation script corresponding to restriction information, and presents the navigation information to the user as discussed by the authors.
Abstract: When a navigation script has a contradiction with respect to time and place, a navigation information presenting apparatus adjusts the contradiction, executes instructions of the navigation script corresponding to restriction information, and presents the navigation information to the user. In addition, the navigation information presenting apparatus presents navigation information to the user at a timing corresponding to information representing traveling speed and/or time step.

TL;DR: In this paper, user interlace commands and navigational data are communicated between a personal navigation device and a media head unit of a vehicle, the user interface commands and navigation data being associated with a device user interface of the device, and a vehicle navigation user interface at the media-head unit displays navigational information and receives user input for control the display of the information.
Abstract: Vehicle data generated by circuitry of a vehicle is received and functions of a personal navigation device, which are otherwise used to process device navigational data that are generated by navigational circuitry in the personal navigation device, are used to process the vehicle data to produce output navigational information. User interlace commands and navigational data are communicated between a personal navigation device and a media head unit of a vehicle, the user interface commands and navigational data being associated with a device user interface of the device, and a vehicle navigation user interface at the media head unit displays navigational information and receives user input for control the display of the navigational information on the media head unit, the vehicle navigation user interface being coordinated with the user interface commands and navigational data associated with the device user interface.

TL;DR: It is found that the Tactile Wayfinder freed the participants' attention but could not keep up with the navigation system in terms of navigation performance, and no significant difference was found in the acquisition of spatial knowledge.
Abstract: In this paper we report on a field study comparing a commercial pedestrian navigation system to a tactile navigation system called Tactile Wayfinder. Similar to previous approaches the Tactile Wayfinder uses a tactile torso display to present the directions of a route's waypoints to the user. It advances those approaches by conveying the location of the next two waypoints rather than the next one only, so the user already knows how the route continues when reaching a waypoint. Using a within-subjects design, fourteen participants navigated along two routes in a busy city centre with the Tactile Wayfinder and a commercial pedestrian navigation system. We measured the acquisition of spatial knowledge, the level of attention the participants had to devote to the navigation task, and the navigation performance. We found that the Tactile Wayfinder freed the participants' attention but could not keep up with the navigation system in terms of navigation performance. No significant difference was found in the acquisition of spatial knowledge. Instead, a good general sense of direction was highly correlated with good spatial knowledge acquisition and a good navigation performance.

TL;DR: In this paper, a method for improved navigation using the global positioning system (GPS) is described. But this method is based on the position information and the destination, and the navigation information is generated by the navigation server.
Abstract: Embodiments of the present invention include systems and methods for improved navigation using the global positioning system (GPS). A method of improved navigation includes transmitting a destination to a navigation server through a wireless communication channel. The method further includes transmitting position information from a GPS-enabled device to the navigation server through the wireless communication channel automatically at a time interval. The method further includes generating navigation information by the navigation server. The navigation information is based on the position information and the destination. The method further includes receiving navigation information on the GPS-enabled device from the navigation server through the wireless communication channel.

TL;DR: The evaluation results show that Travi-Navi can track and navigate users with timely instructions, typically within a 4-step offset, and detect deviation events within 9 steps.
Abstract: We present Travi-Navi - a vision-guided navigation system that enables a self-motivated user to easily bootstrap and deploy indoor navigation services, without comprehensive indoor localization systems or even the availability of floor maps. Travi-Navi records high quality images during the course of a guider's walk on the navigation paths, collects a rich set of sensor readings, and packs them into a navigation trace. The followers track the navigation trace, get prompt visual instructions and image tips, and receive alerts when they deviate from the correct paths. Travi-Navi also finds the most efficient shortcuts whenever possible. We encounter and solve several challenges, including robust tracking, shortcut identification, and high quality image capture while walking. We implement Travi-Navi and conduct extensive experiments. The evaluation results show that Travi-Navi can track and navigate users with timely instructions, typically within a 4-step offset, and detect deviation events within 9 steps.
