Animation can provide effective emphasis if used correctly, but give careful thought to whether animation is warranted. The human eye is attracted to animated elements. If the user's attention needs to be elsewhere, animation might increase user errors.
Useful animations include progress or status animations. For details, see Progress Animation and Status Animation. Other uses of animation include an animated graphic that activates when the user empties the trash or when the system state changes.
Limit animation to situations that provide meaningful feedback to the user.
The following figure shows an interesting use of animation in a process control application. The progress bar does not track the progress of the operation; rather, it acts as a gauge to show the temperature of a vat in a candy factory. The progress bar indicates what proportion of the maximum temperature has been reached (more than three-quarters), and the text message within the progress bar specifies the exact temperature (114 degrees) of the vat's contents.Figure 42 Text Inside a Progress Bar
If you write a message to display inside a progress bar, make it concise. Otherwise, localized text might outgrow the progress bar.
