ISO/IEC 18035 applies to icons that are shown on a computer screen, that users can manipulate and interact with, and that represent computer system functions. ISO/IEC 18035 describes user interaction with and the appearance of multimedia control icons on the screen. Other forms of icons are covered in ISO/IEC 11581 — Information technology — User system interfaces and symbols — Icon symbols and functions. This international standard defines a consistent set of icons and related functions that are presented by multimedia applications on a computer screen and that users interact with to control such applications. These control icons typically represent actions by association with conventional controls on hardware devices (for example video recorders and compact disk players) that prompt the user to recall the intended actions. This standard provides a consistent set of controls for such functions as: Play, Pause, Stop, Rewind, Fast forward, Scan forward, Scan backward, Replay, Play backward, Loop, Record, Go to beginning, Go to previous, Go to next, Go to end, Set volume and Mute.
