Direct Manipulation and Other Styles of Man-Machine Interaction

摘要

As new technologies are used in computer hardware, such as fast refresh graphics screens, and as people began to realize that common computer interaction could be difficult, a new and, to the user often more comprehensible computer dialogue style has emerged. Using that dialogue style, users interact with the computer system by directly manipulating the object of interest presented on the screen. Schneiderman called this new dialogue style Direct Manipulation (DM). A precise description of DM along with conventional dialogue styles is given. DM interfaces often cause unique problems, compared with other dialogue styles. In the report these problems, their causes and possible ways of solving them are discussed.
