Abstract

The invention belongs to the technical field of geospatial information systems, and provides an immersive spatio-temporal data visual analysis multi-view layout method and system, aiming to solve the discontinuity and cognition between multiple views of the analyst existing in the prior art inefficiency etc. The method includes establishing a view layout space; calculating the attention degree of each view in the current stage of the visual analysis task; calculating the degree of association between the views in the current stage of the visual analysis task; Gaze change information of the position, or according to the analysis change information of a view about view data by the analyst, according to the degree of association between other views and this view and the degree of attention of other views, determine the corresponding view from other views and make it Linkage response. The method dynamically optimizes the multi-view layout, realizes the cognitive focus related to the visual analysis task, and maintains the continuity and efficiency of the analyst's cognition among 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...
