  • how interactive maps and geo visualization help to explore and communicate multivariate data
  • A computer’s image of human beings is reflected by its input and output devices. In the case of most desktop computers, this means a mouse, a keyboard, a monitor, and speakers. To such a computer we might look like a hand with one finger, one eye, and two ears. To change how the computer reacts to use, we have to change how it sees us." Physical Computing, Dan O’Sullivan and Tom Igoe (2004)
  • non standard interaction elements
  • non-standard
  • Koolhaas
  • Paper cards Interactive surface
  • Paper prototyping
  • information display is governed by an underlying metadata structure in the form of a concept network, which is based on characteristics of the exhibits
  • The co-occurrences in such metadata define the visual connections among exhibits.
  • Place physical cards (with fiducials) on table
  • Mæve shows a way of providing new browsing experience by combining tangible interaction, complex visualization and collaborative data examination By inspecting conceptual relations on the table, visitors can find other significant works, or understand how their interests connect to information shared between exhibits. The simplicity of placing a card on the table imposes a low barrier to start interacting with the system. The visualization aesthetics and feedback invites users to explore both interaction mechanisms and displayed information without demanding great amount of concentration.
  • 1,0 x 0,9 m , Full HD, 30 ppi
  • OpenStreetMap, reduced style. Give a rough idea on spatial location (for citizens knowing the area)
  • Physical object acts as tangible input device and can be used to select various faceted data and filter the projects In the design of the object we opted for a shape signifying the interaction possibility to select different facets, hinting to the literal meaning of a “facet”, to make it crystal-clear.
  • Unfold the object, unfold the data
  • Unfolding

  • First results suggest the tangible interaction with the polyhedron reduces the barrier between the physical world and virtual data, and eases the understanding of faceted geographical data. Thus enabling urban planners and citizens alike to participate in the discovery and analysis of information referring to the physical world.
  • Other issues Large-scale tabletop display Connections between projects
  • Lots of visualizations Country list with sparkline
  • Subtle, yet noticeable - Teaches the user a concept, thus - Helps flatten the learning curve

  • The trick is knowing what is what, for what, when, for whom, where, and most importantly, why. Those who try the replace the mouse play a fool’s game. The mouse is great for many things. Just not everything. - Was sind die sinnvollen Einsatzmöglichkeiten von big scale gesture interfaces? (multitouch, tangible, ...)? - Wie kann angemessen erweitert werden?
