Nested fisheye view focus calibration method

Abstract

The invention provides a nested fisheye view focus calibration method which comprises the following steps: firstly, designing a fixed-length fisheye algorithm and enabling the total dimension of all nodes of a fisheye algorithm component to remain constant and unchanged; secondly, applying the fixed-length fisheye algorithm to a focus area, ensuring that the position and the length of the whole focus area remain unchanged, and the nodes in the focus area are only changed along with the movement of the mouse when a mouse moves within the scope of the focus area; and ensuring that the focus area only can move along with the mouse only when the mouse moves out of the focus area. With the adoption of the nested fisheye view focus calibration method, the change degree of the component is reduced when the mouse moves in a fisheye view component, so that a user can more easily select a target option in the component, thereby the problem that the focus is hard to calibrate in common fisheye view is solved, and the defects in the prior art are compensated.

Description

technical field [0001] The invention belongs to the technical field of fisheye view based on focus and context technology, and in particular relates to a nested fisheye view focus calibration method. Background technique [0002] With the advancement of computer science and the continuous development of information technology, more and more information can be easily obtained. The vast majority of users are facing the difficulty of having too much data to display on a relatively small screen. How to reduce the cost of information access so that users can obtain the maximum amount of information in the shortest possible time is a major problem that needs to be solved in the field of information visualization. The existing traditional solutions are: [0003] (1) ROLLING. Scrolling, which is scrolling data in and out of the visible area, is an obvious solution. For example, in a word processing program, a very long document can be scrolled within a window until it reaches th...
