The Principles of Universal Design
Principle 6: Low Physical Effort

Example
The automatic sink with soap dispenser, as shown to the right, has the following advantages:
- increases sanitation
- increases usability for all users by eliminating most of the physical effort
- reduces repetitive motions of turning handles or knobs on and off
Example
