Preliminary Exploration of Three-dimensional Visual Variables in Virtual Reality

As a theoretical basis for the design of plane graphic symbols, visual variables play a very important role in the symbolization of plane maps. However, the visual variables in plane map symbols are not fully applicable to three-dimensional models. This paper combines the features of virtual reality technology and integrates the aGlass VR eye tracking module with HTC Vive virtual reality devices, selects the basic visual variables (colour, size and spatial pose) in the three-dimensional scene for research. We organized and extracted the research process, and in this way, constructed set of incompletely mature research frameworks for visual variables.
