| As a display medium that has become more and more popular in recent years,large screen can meet the expression requirements of massive information by virtue of its high-resolution,large-scale display area and other display characteristics,providing a new window for the visualization of big data.Big screen has become the main tool in the new working mode in various fields.At the same time,with the deepening of GIS in the market industry,the application of GIS large display has become a new way to display spatial information for multi-user groups.User interface of GIS needs a more adaptive design method to realize the visual transmission under the large screen.However,there are few researches on the solution and design optimization of the graphic interface design strategy under the large-screen display environment.In order to solve the problem of migration of GIS user interface to large screen,this study firstly concludes the general display features,application environment features and interaction modes of GIS large display by comparing the large-size screen with the traditional size screen.Secondly,according to the particularity of the large-screen display and considering the user’s cognitive habits,eight user vision and application patterns of the large-screen geographic information system are summarized(It mainly involves user’s vision,memory and reading mode that are compatible with the large-size display features,user’s perception of the interface color and scene effect in the large-screen environment,and user’s cognition and understanding of spatial information in GIS large screen).Then,on the basis of the large-screen feature mode,GUI design strategies adapted to the GIS large-screen are further proposed,including the overall design content such as interface layout and color configuration,and mainly focuses on geographical space and spatial information which are the crucial part of GIS interface.Map design includes the configuration of the map space and the selection of the map elements while spatial information is discussed in two types those are map form and non-map form.At the same time,it tries to apply the design methods of dynamic effects and special effects,and brings forward the design method of dynamic relationship and static element expression for large-display spatial information.Finally,taking Shanghai police large screen as an example and verifying the proposed design strategies.And the personalized UI design and diverse spatial information expression for large-screen users were basically realized in this case.The design strategy proposed in this paper contains many aspects of map and spatial information representation,focusing on the needs and feelings of large-screen users,and integrating artistic expressions in interface design such as science fiction movies.In further research,it is necessary to expand the diversified design and expression methods of geographic information elements,improve the user usability evaluation mechanism,and meet the dual needs of users in terms of both visual and cognitive... |
