Investigating the Use of Spatial Interaction for 3D Data Visualization on Mobile Devices
summary
Study implements three 3D visualizations on a tracked tablet and compares spatial interaction to touch across three tasks (navigation, 3D bar comparison, structural understanding) with 18 participants. Spatial input maps device position to a virtual camera; touch uses an orbit camera with one‑ and two‑finger gestures. Results show navigation task faster with spatial input, no performance gain for comparison or structure tasks, but higher perceived control and greater physical demand; camera trajectory plots reveal distinct interaction patterns.
