From Computing and Software Wiki
The Direct Manipulation Method
Direct manipulation is the visual representation of the world of actions. For example, the desktop metaphor (Microsoft Windows) which the user can manipulate. Direct manipulation is one of the primary interaction styles which has been used by designers and programmers for their systems. Direct manipulation allows novice users access to powerful instructions without the trouble of learning how to use a complex syntax and/or extensive lists of commands.
Direct manipulation involves three interconnected techniques:
- Provide a physically direct way of moving a cursor or manipulating the objects of interest.
- Present a concrete visual representation of the objects of interest and immediately change the view to reflect operations.
- Avoid using a command language and depend on operations applied to the cognitive model which is shown on the display.
