Problems solved by technology

Due to the transformation of the layout space from a two-dimensional plane to a 360-degree three-dimensional space surrounding the analyst, and the development of analysis tasks from data visualization to visual reasoning in the analysis process, the traditional multi-view layout method has been unable to meet the needs of immersive visual analysis.

Abstract

The invention belongs to the technical field of geospatial information systems, provides a multi-view layout method and system of immersive spatiotemporal data visual-analysis, and aims to solve the problems which are of discontinuity, low efficiency and the like of cognition of analysts among multiple views and exist in the prior art. The method includes: establishing layout space of the views; calculating degrees of attention on all views of a current stage of a visual-analysis task; calculating degrees of association among all the views of the current stage of the visual-analysis task; anddetermining a corresponding view from the other views according to gazing change information which is of an analyst, on the one view and about a view position or analysis change information which is of the analyst, on the one view and about view data, degrees of association between the other views and the view and degrees of attention on the other views, and enabling the same to carry out linkageresponse. According to the method, a multi-view layout is dynamically optimized, and cognition focusing associated with the visual-analysis task is realized to maintain continuity and high efficiencyof cognition of the analyst among the multiple views.

Description

technical field [0001] The invention belongs to the technical field of geospatial information systems, and mainly relates to a multi-view layout method and system for immersive spatiotemporal data visual analysis. Background technique [0002] With the rapid development of AR / VR technology, immersive experience has been gradually applied in the field of data analysis, and the immersive visual analysis of spatio-temporal big data has become a hot research frontier in academia and industry. [0003] The traditional multi-view method represents information in different forms from different sides and realizes the visualization of multi-dimensional features of data. The layout design standard mainly considers the continuity of the analyst's cognition of different features. Unlike traditional visual analysis, where multiple views are mainly arranged in a two-dimensional plane, the multi-view layout space of immersive visual analysis is centered on the analyst and surrounds the ana...
