In an era of information overload, many people struggle to make sense of complex stories, such as presidential elections or economic reforms. We propose a methodology for creating structured summaries of information, which we call zoomable metro maps. Just as cartographic maps have been relied upon for centuries to help us understand our surroundings, metro maps can help us understand the information landscape.

We present G-nome Surfer 2.0, a tabletop interface for fostering inquiry-based learning of genomics. We conducted an experimental study with 48 participants that compared students' learning of genomic concepts using existing bioinformatics tools and using two alternative implementations of G-nome Surfer: a collaborative multi-mouse GUI and a tabletop interface. Our findings indicate that G-nome Surfer improves students' performance, reduces workload, and increases enjoyment. The comparison of tabletop and multi-mouse implementations further shows that the tabletop condition results in four educational benefits: 1) increasing physical participation, 2) encouraging reflection, 3) fostering effective collaboration, and 4) facilitating more intuitive interaction.
