Abstract
The feeling of directness arises when the interface permits the user to manipulate an interface object in a way analogous to manipulating the real object. However, we argue here that the essence of direct manipulation is not directness per se, but manipulation of task relevant objects in a task relevant manner. The research reported studies users of HyperCard after 20 hours of practice. We found that when users deviated flom taught strategies that 25% of the time they invented new strategies that attempted a more direct manipulation of the task object than that permitted by the design of the interface.
