Abstract : Choices among techniques and hardware devices which allow users to interact with a computer-generated environment through computer graphics are described an discussed. These interaction techniques provide communication with the system through commands and information associated with the commands. Each technique has some purpose, such as to specify the command, designate a position, or select a displayed object, and each is implemented with some device, such as a tablet, joystick, keyboard, light pen, track ball, or potentiometer. Important human factors issues, experiences, and experiments bearing on the selection of one technique or device in favor of another are presented. A way to precisely describe an interaction technique, the interaction technique diagram, is introduced. Nine relevant experiments are abstracted and critiqued, and their experimental procedures are described using the technique diagrams.
