Material Interactions with Tangible Tabletops:
a Pragmatist PerspectiveNicolai Brodersen Hansen; nbhansen@cavi.au.dk

The Radar Table
Radar Table?• Research interest in design materials
• Few detailed qualitative studies of tangible tabletops “in the wild”
• Complex phenomena with a strong material component
• General interest in developing pragmatism as a foundation for interaction design and HCI.
Material interactions with tangible tabletops
• Contribution: theoretical framing based on pragmatism
• Focus on the material aspects of the interface
• Exploration of form and sound
Pragmatist framework
• Problematic situations
• Inquiring strategies
• Technology supporting inquiry
The Radar Table
The Radar Table• 80 cm x 107 cm translucent table surface
• Underneath: a projector and a camera connected to a computer
• Tangible objects with visual markers tracked by camera: position, and rotation
• Sample objects and effect objects
• Visuals and sounds projected and played
The Radar Table
The Radar Table; Design principles
• Support walk up and use
• Encourage exploration
• Support both individual and social play
• Enable emergent use
Deploying the Radar Table
• Spot 2013; Music Festival for small upcoming bands
• Filmed topdown with a GoPro camera
• Roughly 6.5 hours of video
Analysis
• Video material analysed and condensed
• Typical instances of use identified
• Then interpreted through the concepts of situation, inquiry and technology, drawn from Dewey’s pragmatism
Pragmatism: Situation
• Situation is the assemblage of a subject, and his/her environment, including other people, things, spaces, and social constructs
• ”Determinate” (or stable)
• ”Indeterminate” (or unstable)
Pragmatism: Inquiry
• Inquiry is the process by which we deliberately try to improve and reshape a situation, so it becomes increasingly desirable or stable
• Dynamic and distributed; instrumental
• Experimental
• Transformation - gradual
Pragmatism: technology
• Instrumental use in inquiry undertaken by participants
• Constrains and enables certain kinds of transformations
• Constitutes the entire situation
Pragmatist framework
• Problematic situations
• Inquiring strategies
• Technology supporting inquiry
Problematic situations• What can I do here?
• What is the interplay between the table and sound?
• What is the relationship between the different tangibles?
• How can I manipulate individual sounds?
• What would make the current soundscape sound better?
• What would I do if this were a "live performance"?
Inquiry strategies• Turn over tangibles
• Add/remove tangibles
• Remove all tangibles
• Slowly and methodically tweak tangibles
• Observe others
• Converse with others
Technology supporting inquiry• People… using
• Tangibles… to experiment with..
• … interactive sounds
Conclusions• the Radar Table “in the wild” is a diverse and situated
experience: no two experiences end and start in the exact same way.
• Inquiry evolves through stages of experimental learning and doing
• experimental learning and doing is distributed across people, tangibles and sound
• Pragmatism offers a potential framework for analysing the above points in practice.
