Analyzing the CD Player Interface

• The visual analogy is obvious if you’re already familiar with a physical CD player

  • “Metallic” buttons
  • CD “slot”
  • Slider for volume

• The icons (images) on the control buttons are familiar

• The names on the “mode” buttons are suggestive of the capabilities of an audio CD, and can be guessed

• As the slider moves up and down, the volume of sound provides immediate feedback

• The “single-pass” icon changes to a continuous loop icon when clicked, suggesting it’s meaning
