Icon animation and audition :
Animation :
Icon Animation: Icon animation involves making icons on a computer screen appear to move instead of staying in one place. There are two main types of animation: static and dynamic
- Static Animation:
- In static animation, an icon’s appearance remains unchanged over time and only changes when a specific system event occurs.
- For example, the open door of a mailbox may close when an electronic message is received.
- Dynamic Animation:
- Dynamic animation involves icons that move independently of system events, representing functions, processes, states, or state transitions.
- For instance, an icon might start moving to illustrate an action when a pointer is moved close to it.
- Purpose of Animation:
- Animation is used to offer feedback and create visual interest in the user interface.
Audition :
Audition (Sound Feedback): Audition involves incorporating sounds into the user interface for various interactions with objects on the computer.
- Sounds for Interactions:
- Objects produce sounds when touched, dragged, bumped, opened, activated, or discarded.
- Auditory Icons:
- These are computer sounds mimicking everyday events. For example, the sound of a printer’s mechanism when it starts printing.
- Feedback and Information:
- Sounds convey information about events, such as the size of a file or the speed of an ongoing process.
- Examples of Auditory Feedback:
- The sound of a large file could indicate its size.
- Dragging an object over a surface produces a sound related to that surface.
- The speed of a process is reflected in its corresponding sound.
- Application in Computing:
- Auditory feedback is useful for conveying information about interactions, ongoing processes, and modes.
- It aids in navigation and supports collaboration among users.
