This 1997 image depicted a visually impaired woman, as she was using a thermostat that had been designed with features, which took into account the needs of end users with vision impairment. Design elements including tactile variations, enlarged numerals, a large, easily rotatable control dial, and a click noise cue, as the temperature was being set, helped to negate difficulties that might be encountered by such visually, or mobility impaired individuals.

“The Center for Universal Design (CUD) is a national information, technical assistance, and research center that evaluates, develops, and promotes accessible and universal design in housing, commercial and public facilities, outdoor environments, and products. The mission is to improve environments and products through design innovation, research, education and design assistance.”

Universal Design Principles/Guidelines:

- Facilitate the user's accuracy and precision

- Use different modes (pictorial, verbal, tactile) for redundant presentation of essential information

- Provide adequate contrast between essential information and its surroundings

- Maximize "legibility" of essential information

- Differentiate elements in ways that can be described (i.e., make it easy to give instructions or directions)

- Provide compatibility with a variety of techniques or devices used by people with sensory limitations
