Revisitation and biologists


          Heavy web users

          Go from on website to another
          to analyse data

          Use a lot of online forms, and
          copy/paste to transfer data

          Bookmarks and history helpful
          but not enough

Preliminary Study of Biologists


       20 biologists / bio-informaticians interviewed

              Strong habits:
              smooth integration in their workflow
              Exploratory navigation:
              interaction
              Redundancy:
              need to manage different versions of the same data
              Data flows:
              copy/paste to chain steps
