2. Enhanced Usability:
Makes the graphic overlay elements more visible in dim lighting, helps users
identify the correct control options, and serves as an indicator of active
functions.

2. Aesthetics: The
backlighting options should be carefully chosen based on the usability
requirements and the general layout of the graphic overlay to enhance the aesthetic
appeal of the product.…
