Description:This 1996 image depicted a person turning on an articulated-arm desk lamp by using the palm of her hand, and pressing against the top of the lamp, at which point she’s able to rotate the large, knurled disk, which is connected to the switch itself. The large size meant that people with limited grasp, or hand strength could activate such a switch with minimal effort. It also meant that less force was needed to turn the lamp on or off. This added feature would make the user's activity a relatively effortless experience. “The Center for Universal Design (CUD) is a national research, information, and technical assistance center that evaluates, develops, and promotes accessible and universal design in housing, buildings, outdoor and urban settings and related products.”
“The CUD conducts original research to learn what design solutions are appropriate for the widest diversity of users, and what tools are most useful to practitioners wishing to successfully practice universal design. The Center collaborates with builders and manufacturers on the development of new design solutions. It also develops publications and instructional materials, and provides information, referrals and technical assistance to individuals with disabilities, families, and professionals nationwide and internationally.”

Universal Design Principles/Guidelines:

- Make the design appealing to all users

- Facilitate the user's accuracy and precision

- Allow user to maintain a neutral body position

- Use reasonable operating forces

- Accommodate variations in hand and grip size
