Exploring Effective Immersive Approaches to Visualizing WiFi

Abstract

Figure 1: Our two novel visualization techniques and the state-of-the-art technology we use for comparison. All three visualizations are paired with Oriented and Segmented glyphs which provide per-router frequency information. The Oriented Segmented Glyphs can be found on the floor. Top left: The Stacked Bars visualization. Routers are ordered on the wall based on their signal strength ranking at that location. The line's thickness represents the router's signal strength. Top Right: Wavelines. Both the line height and its thickness encode signal strength. Bottom Left: Contour lines. The baseline that we used as a comparison point for our analysis. Each router is surrounded by concentric ellipsoids whose center represents the signal source's location. Bottom Right: Application features available to participants in our study including a minimap with positional and directional cues, 3D marker (red sphere on the wall), and selection preview (sphere above controller).
