Abstract:

The authors describe an experiment to see if large breadth and decreased depth is preferable, both subjectively and via performance data, while attempting to design for optimal scent throughout different structures of a web site. This work is testing the theories of Miller in his classic 'The Magical Number Seven, Plus or Minus Two.'
