A visualization paradigm for 3D map-based mobile services

Abstract

Nowadays, there is a wide range of commercial LBMS (Location- Based Mobile Services) available in the market, and a trend towards the display of 3D maps can be clearly observed. Given the complete disparity of ideas and a visible commercial orientation in the industry, the study of the visualization as- pects that influence user performance and experience in the exploration of urban environments, using 3D maps, becomes an important issue. Based on a proposed conceptual framework, an online questionnaire was developed and administered in order to measure the real impact of each element. Combining the experimental results with the current state-of-the-art, a new visualization paradigm is defined in a dual specification: 'layers' providing relevant visual content to the map, and 'functions' providing the necessary functionality.
