Research review: Synchronizing Spatial Information

Synchronizing Spatial Information in Complex Environments: a Crossover Of Space Syntax And Spatial Information Visualization; IST, Lisbon

A related research was conducted by Teresa V. Heitor, Ana Tomé, Paulo Dimas and João P. Silva at the Instituto Superior Técnico, Lisbon, Portugal, starting from January 2006. With the backgound in Spatial Syntax and the interest in building a Space-use analysis model, the focus of this research was on knowledge sharing scenarios and its spatial patterns. To be able to correlate the extension of AP signals with the physical space, they proposed a space-use analysis model (SUAm) that explores relationships between “the virtual web space (user communication in a more or less ubiquitous field) and the physical space (users movements in a more or less permeable system)”. In their paper “Synchronizing Spatial Information In Complex Environments: a crossover of space syntax and spatial information visualization”(Heitor et al. 2007)⁠, they drew a parallel between *permeability* of the virtual space of the Internet and *ubiquity* in the physical space. Starting from the theoretical signal propagation model, the team analysed signal coverage distorted by the built barriers in buildings and by equipment in rooms, thus determining the range of each AP in space. They created diagrams of signal propagation. The Space-use analysis model was developed using activity categorisation tagging of access points (Communicating, Creating, Decision making, Delivering, Applying) conclusion: “WiFi network shows capacity to function as an ad-hoc WiFi user trace system.”
