Explore a conference talk examining the impact of Tangible User Interfaces (TUIs) on spatial memory. Delve into a study comparing TUIs with touch-based GUIs on interactive tabletops for recalling building positions. Learn about the surprising results that contradict participants' self-assessments, showing a 24.5% increase in accuracy when using TUIs. Gain insights into the potential of TUIs for enhancing collaboration and learning through physical manipulation of digital information. Understand the methodology, results, and implications of this research presented at the ACM Symposium on Spatial User Interaction.
