Principle 4 PERCEPTIBLE INFORMATION
The design effectively gives necessary user information, regardless of prevailing conditions or sensory disabilities (e.g., low vision or hearing loss).
Varied methods such as pictures, voice, and touch repeat the important points (redundant cues) so everyone can get it right even in confusing situations. Necessary information is as visible and readable as possible. Product directions and parts are broken into small, easy steps. The design also works for people who use assistive devices to help them see, hear, or touch.
