summary

Built a cross-device system with a shared tabletop map of the Canadian Arctic and personal tablets linked by an ROI bounding box; two interaction techniques are compared: TOUCH (directly drag ROI on table) and TILT (hold-edge button + tilt to scroll). Twelve pairs perform a sensemaking route task; TOUCH is preferred despite reach problems, with 83% vs 66% reporting easy coordination (statistically significant) and 67% reporting they cause interference. Findings highlight user-agnostic ROI delegation and tablet tableau comparisons as enablers of tight joint work.
