12. Experimental task:
Identify the molecular basis of an unclassified motor mutation in mice
Existing web-based bioinformatics tools G-nome Surfer with multi-mouseGUI G-nome Surfer
Macroscopic Evaluation:
Comparative study with 48 students

14. Evaluating Collaborative Problem Solving
• Quantitative measures
– Number and value of
insights
– time per activity
– subjective workload
– attitude
– physical and verbal
participation
– equality of participation
• Qualitative indicators
– collaboration style
– problem-solving strategy
– nature of discussion

15. Findings
• G-nome Surfer improves students performance,
reduces workload, and increases enjoyment
(compare to current state-of-the-art bioinformatics
tools)
• The tabletop prototype (compare to multi-mouse
interface):
– Increases physical participation
– Encourages reflection
– Fosters effective collaboration
– Facilitates more intuitive interaction

25. Going forward
1) Reality-based interaction offers unique opportunities for
enhancing discovery and learning in data-intensive areas.
2) Designing interaction for problems in genomics can help move
forwards the theory and practice ofTEI.
3) Future research includes:
How to visualize and engage data, activity, progress spanning
many systems, people, places, timescales?
What representational forms, device ecologies, most
appropriate for large, abstract data?
Facilitating engagement with big data in ways that highlight
connections between multiple forms of evidence
26. Lessons learned and Going Forward
RBI can facilitate immediate, visible, and easily reversible manipulations
• How to designTEI for open-ended creative inquiries?
Visual representations can facilitate multi-stage workflows
• Important for execution and tracking of complex analyses
• Need parametrized, annotatable representations of complex large datasets
RBI could facilitate collaboration for co-located teams
• Large interdisciplinary teams and distributed work are common in this area
• Users can jointly manipulate assumptions and see consequences
RBIs can support understanding and discovery
• Provide access to different pieces of the problem (data, reactions)
• Help users forms accurate mental models through tangible/embodied manipulation
