But great designers are content with a well-used design…and know that happy users are often silent. Keep secondary actions secondary by making them lighter weight visually or shown after the primary action has been achieved. Patrick Dickson, Principle Investigator; software designers, Carrie Heeter and Pericles Gomes, Comm Tech Lab, Michigan State University, 1990.
What kinds of objects would it contain, and how would you manipulate them? A tool is something you look at and control. Hand-position sensing: Gives control of views based on commands given through hand and finger positions Hand-held manipulatives: Force feedback and haptics Sound input and output: Immerse the users by adding appropriate sound cues. Future interfaces will provide tactile cues. There are 4 or 5 windows open at the same time. Visibility seems simple enough: can you perceive something yes or no?
