In this paper, we reflect on the design, development, and deployment of G-nome Surfer; a multi-touch tabletop user interface for collaborative exploration of genomic data. G-nome Surfer lowers the threshold for using advanced bioinformatics tools, reduces the mental workload associated with manipulating genomic information, and fosters effective collaboration. We describe our two-year-long effort from design strategy to iterations of design, development, and evaluation. This paper presents four main contributions: (1) a set of design requirements for supporting collaborative exploration in data-intensive domains, (2) the design, implementation, and validation of a multi-touch tabletop interface for collaborative exploration, (3) a methodology for evaluating the strengths and limitations of tabletop interaction for collaborative exploration, and (4) empirical evidence for the feasibility and value of integrating tabletop interaction in college-level education. |
