TL;DR: A novel approach to adaptive navigation in the interactive virtual world by using data from the user that enables adaptive changes to the virtual world over time and provides user-preferred path weights for smart-agent path planning.
Abstract: We present a novel approach to adaptive navigation in the interactive virtual world by using data from the user. Our method constructs automatically a navigation mesh that provides new paths for agents by referencing the user movements. To acquire accurate data samples from all the user data in the interactive world, we use the following techniques: an agent of interest (AOI), a region of interest (ROI) map, and a discretized path graph (DPG). Our method enables adaptive changes to the virtual world over time and provides user-preferred path weights for smart-agent path planning. We have tested the usefulness of our algorithm with several example scenarios from interactive worlds such as video games. In practice, our framework can be applied easily to any type of navigation in an interactive world. In addition, it may prove useful for solving previous pathfinding problems in static navigation planning.

19 Jun 2009TL;DR: In this article, a navigation system is provided for instructing an operator of a vehicle, which includes a navigation processor configured to obtain a destination location, and to generate a proposed route to the destination location.
Abstract: A navigation system is provided for instructing an operator of a vehicle. The navigation system includes a navigation processor configured to obtain a destination location, and to generate a proposed route to the destination location. The navigation system also includes a presentation element coupled to the navigation processor, the presentation element configured to provide navigation instructions to the operator. The navigation system also has a selection module coupled to or incorporated into the navigation processor. The selection module is configured to select a designated navigation instruction scheme from a plurality of different navigation instruction schemes. For a given navigation instruction, the plurality of different navigation instruction schemes provide different instruction content. During operation, the presentation element provides navigation instructions for the proposed route, using the designated navigation instruction scheme.

25 Sep 2015TL;DR: In this paper, the authors present a technique for determining whether data associated with an autonomous navigation of an unmanned vehicle may be trusted. But, their approach assumes that the data is provided from a source external to the unmanned vehicle.
Abstract: Techniques for determining whether data associated with an autonomous navigation of an unmanned vehicle may be trusted. For example, navigation-related data may be provided from a source external to the unmanned vehicle. Image data associated with the autonomous navigation may be generated. The navigation-related data and the image data may be compared to determine whether the navigation data may be trusted or not. If untrusted, the autonomous navigation may be directed independently of the navigation data.

TL;DR: iWalk is presented, a speech-enabled local search and navigation prototype for people with low vision that provides real-time turn-by-turn walking directions in speech and text, using distances and time-to-turn information in addition to street names so that users are not forced to read street signs.
Abstract: Smart phones typically support a range of GPS-enabled navigation services. However, most navigation services on smart phones are of limited use to people with visual disabilities. In this paper, we present iWalk, a speech-enabled local search and navigation prototype for people with low vision. iWalk runs on smart phones. It supports speech input, and provides real-time turn-by-turn walking directions in speech and text, using distances and time-to-turn information in addition to street names so that users are not forced to read street signs. In between turns iWalk uses non-speech cues to indicate to the user that s/he is 'on-track'.

TL;DR: In this paper, the authors propose a method to automatically divide the pages of a web site on the basis of user logs into sets of pages that correspond to navigation stages, which can be used in combination with the pages' topics to give better recommendations or to structure or adapt the site.
Abstract: Users of web sites often do not know exactly which information they are looking for nor what the site has to offer. The purpose of their interaction is not only to fulfill but also to articulate their information needs. In these cases users need to pass through a series of pages before they can use the information that will eventually answer their questions. Current systems that support navigation predict which pages are interesting for the users on the basis of commonalities in the contents or the usage of the pages. They do not take into account the order in which the pages must be visited. In this paper we propose a method to automatically divide the pages of a web site on the basis of user logs into sets of pages that correspond to navigation stages. The method searches for an optimal number of stages and assigns each page to a stage. The stages can be used in combination with the pages' topics to give better recommendations or to structure or adapt the site. The resulting navigation structures guide the users step by step through the site providing pages that do not only match the topic of the user's search, but also the current stage of the navigation process.
