INTRODUCTION
• Tabletop Tangible Interfaces (TTIs) have emerged as a research topic in the field of tangible computing.
• TTI system like Urp• The physical objects in TTIs in general, and also in Urp,
are inert.
INTERACTION TECHNIQUES
• Interaction feedback– Haptic feedback– Interaction assistance
• Interaction commands– Indirect interaction– Imitation
• Group interactions• Model-based interactions
Interaction feedback
• Haptic feedback• Interaction assistance
Interaction commands
• Indirect interaction• Imitation
Group interactions
• Users can control multiple tangibles at once by applying interaction commands to a group.
Model-based interactions
• A user rotates a tangible to adjust the temperature in Celsius. The left tangible rotates proportionally to ensure consistency between the two temperature scales.
DESCRIPTION OF HARDWARE
• Tabletop• Tangible Bots
IMPLEMENTATION OF INTERACTION TECHNIQUES
• Haptic feedback• Interaction commands• Group interactions
STUDY
• STUDY #1
• STUDY #2
STUDY #1: USABILITY
• Participants• Apparatus• Procedure• Experimental design• Dependent measures
STUDY #1: RESULTS
• Movement• Rotation• Grouping• Satisfaction and comments
STUDY #2: USEFULNESS
• Domain and participants• Interaction design• Procedure
STUDY #2: RESULTS
• based on two sources of data– analyzed the videos showing each of the musician’s
performance.– analyzed the comments of musicians as they where
learning to use the system and during the debriefing.
DISCUSSION & CONCLUSION
• Active tangibles in tabletop interfaces promise to reduce conflicts between the digital model and the spatial layout of tangibles,and to afford new ways of interacting.
