Searching by Panning and Zooming

چکیده
We consider the problem of searching through visualizations of large amounts of data by performing panning and zooming operations. We give algorithms to travel from a source to an unknown target using a number of pans and zooms that is competitive with the optimal number of pans and zooms depending on certain parameters, and consider both the one-dimensional and two-dimensional versions of this problem.

Smooth, Efficient, and Interruptible Zooming and Panning
This paper introduces a novel technique for smooth and efficient zooming and panning based on dynamical systems in hyperbolic space. Unlike the technique of van Wijk and Nuij, the animations produced by our technique are smooth at the endpoints and when interrupted by a change of target. To analyze the results of our technique, we introduce world/screen diagrams, a novel technique for visualizi...
متن کاملZEUS - Zoomable Explorative User Interface for Searching and Object Presentation
In this paper we describe a first version of ZEUS, a web application that combines browsing, searching and object presentation. With the zooming and panning based navigation concept of ZEUS and a hierarchical organization of the information space we try to solve the problems of information overload. It has to be evaluated if categorization, zooming and a full text search can minimize that the u...
متن کاملUsability of Navigation Tools for Browsing Genetic Sequences
Software to display DNA sequences is a crucial tool for bioinformatics research. This study examined techniques for navigating large DNA sequences via panning and zooming. This involved surveying the navigation facilities of current bioinformatics applications and performing a heuristic analysis on the most common interface controls found. Several prototypes for sequence navigation via panning ...
متن کاملQuantitative Color Optical Flow
Abstract We perform a qualitative and quantitative analysis of various multi-frame color optical flow methods for synthetic and real panning and zooming image sequences. We show that optical flow accuracy improvement can be slightly improved if color images are available instead of gray value or saturation images. We show the usefulness of a directional regularization constraint for computing o...
متن کاملAn evaluation of integrated zooming and scrolling on small screens
Navigation within two-dimensional information spaces such as documents, images and spreadsheets is commonly supported by a combination of discrete scrolling, panning and zooming facilities. However, the number of navigational actions increases as the proportion of the space that is visible on a display decreases. The problem of increased navigational effort is exacerbated when using small scree...
