In this paper, we present a novel technique for predicting and visualizing users' future navigations. Here, user navigation is considered as the sequence of URL's visited by the user. We have used distance-based specific trajectory clustering to partition users and integrated with Markov model for predicting users' future navigation. For testing the proposed technique, we developed a tool calle...

This thesis concerns the design of an information navigation and retrieval system where some navigation mechanisms have inherited functionality from concepts found in cognitive science. These mechanisms are intended to improve navigation and information retrieval in large information spaces like the World Wide Web, as well as enhancing the possibility for creative thinking. A model describing t...

In this report the problem of vehicular navigation based on the integration of the global positioning system and an inertial navigation system is tackled. After analysing some fundamental technical issues about reference systems, vehicle modelling and sensors, a novel solution, combining extended Kalman Filtering with particle Fitering, is developed. This solution allows to embed highly nonline...

In order to solve the problems of Image pretreatment and the extraction of navigation line on agricultural machinery visual navigation, a route navigating system based on improved HOUGH transform is brought forward. First, extract the set of points from the original image based on the threshold segmentation and edge detection. Second, an improved HOUGH transform algorithm is used on detecting t...

GPS receivers are widely used in navigation and positioning, due to the global availability of GPS signals, its low cost and low power consumption. However, it does not work sufficiently in all signal environments. This raises the need to integrate GPS with other sensor systems (for instance, the inertial navigation system (INS)) to have a robust, continuous navigation solution regardless of th...

With the explosive growth of the World Wide Web, browsers especially Netscape and Microsoft Internet Explorer have found their users increasing exponentially. Thus minor problems in these browsers affect millions of individuals. The stack based navigation structure of these browsers is one such example. We present the Unified navigation Architecture for Hypertext Applications (UNAHA), which not...

In this paper we describe two approaches for providing a versatile mechanism for retrieval and navigation using spatially related feature selections. As an example, we build colour histograms from images, and use a quadratic histogram match to achieve a retrieval method based on the spatial colour distribution of the images. Navigation is facilitated by a larger architecture, called MAVIS (Mult...

During previous CSUN conferences we presented the navigation system TANIA (Tactile-Acoustical Navigation and Information Assistant). The system’s main component is an Ultra Mobile PC and it achieves positioning of the user via an accurate step-tracking method, GPS, and RFID tags, and works both indoors and outdoors. Besides providing information about the surrounding area by an integrated tacti...

We introduce the notion of Graph Sketches. They can be thought of as visual indices that guide the navigation of a multi-graph too large to fit on the available display. We adhere to the Visual InformationSeeking Mantra: Overview first, zoom and filter, then details on demand. Graph Sketches are incorporated into MGV, an integrated visualization and exploration system for massive multi-digraph ...
