Abstract:
Indoor maps are the information carrier and basis of indoor location services, and the design and visualization of indoor maps would highly influence the transmission efficiency of the map information. The current researches primarily focus on positioning, navigation etc, but little attention is paid to its own design and visualization. Based on lots of domestic and foreign literatures, this paper studies on the template design for the cognition and visualization of indoor space map, which including as follow:
1. This paper summarizes the development status of indoor maps, and put forward a new thought to the design and visualization of indoor maps on the basis of spatial cognition.
2. From the perspective of spatial cognition, analyzing the characteristics of the indoor space, this study summarizes the four main factors which influence the indoor spatial cognition: indoor space clue fuzzy, indoor space structure enclosure, indoor space complex connectivity, the physiological and psychological characteristic of human indoor. According to these four main factors, five principles are organized as: consistency, simplicity, sense of hierarchy, universality, and pertinence.
3. To the integrity of the indoor spatial cognition, we take the most representative shopping mall as example and consider its structure and function features, then the indoor elements can be divided into four categories: basic frame elements, key cognitive elements, main function elements and subsidiary elements. The first three categories were selected to perform the visualization.
Based on the extent of space enclosure and perspectivity of, indoor spatial entity can be divided into five categories: open boundary, half-height and non-transparent boundary, half-height and transparent boundary, full height and non-transparent boundary, and full height and transparent boundary.The enclosure of boundary is represented by different types of line: Solid line represents full height boundary. Dotted line represents half-height boundary. The perspectivity of boundary is represented by lightness of line color. Dark grey (70% grey scale)represents non-transparent boundary. French grey(35% grey scale) represents transparent boundary.
Based on the clue fuzzyness of indoor space, anchoring point theory is introduced to the hierarchical selection and highlighting for main functional element of the anchoring point. The principles of the selection of anchoring point from high to low in turn are: the degree of familiarity of ground object, types of ground types (diet has the priority to be selected), the location of ground object (objects beyond the key points should have the priority to be selected), and the design of ground object itself, in which the first three conditions should be seriously considered. Besides above principles, the density of shops and the classification, space structure, and layout of buildings are also taken into consideration. Following all these principles, twenty percent of the total numbers of shops were selected, highlighting by annotation with different lightness.
4. According to the spatial cognition characteristics and map design principles, we designed the symbols (dot, line, and face shape) of indoor maps by reasonably using the basic graphic variables such as shape, size, color, brightness, and structure. Taking the ground floor of chicony square located in China Wuhan as the object, we designed its indoor maps which improve the effect of the map information transmission.
In this paper, we proposed a referable method for the design and visualization of indoor maps which provides definite theoretical significance and application value.
Keywords: indoor maps, spatial cognition, map design, anchoring point, symbol design
