Path Counting for Grid-Based Navigation

Grid-Based Path-Finding

Grid-Based Navigation for Autonomous, Mobile Robots

Navigation is a major challenge for autonomous, mobile robots. The problem can basically be divided into positioning and path planning. In this paper we present an approach which we call grid-based navigation. Though we also propose a scheme for path finding, we focus on positioning. Our approach uses minimal environmental infrastructure and only two light sensors on the mobile device itself. S...

Speech-Based Navigation: Improving Grid-Based Solutions

Speech-based technology is a useful alternative to traditional input techniques such as the keyboard and mouse. For people with disabilities that hinder use of traditional input devices, a hands-free speech-based interaction solution is highly desirable. Various speech-based navigation techniques have been discussed in the literature and employed in commercial software applications. Among them,...

Counting Cells in a Grid. Counting Cells in a Grid

The goal of this paper is to estimate in a theoretical way the reduction of the number of cells of, and the overall number of neighbouring cells in, a grid when some cells in a uniform grid are replaced by a larger cell in an overlaying non-uniform grid. We assume that the grids are represented by a 2 k-tree and the replacement of cells preserves the representation.

Recommender Systems Based on Navigation Path Features

Several kinds of features of user navigation paths (e.g., subsets of the resources as nodes of the paths covered, subsequences of the sequences used for path description, path fragments constructed via combination of subsequences and wildcards) can be employed to build recommender systems designed for tasks as di erent as site personalization, cross-/up-selling, and navigation assistance.
