The Principles of Universal Design

Hannah: Lever door handles in some ways symbolize access. In contrast to the typical doorknob there are many ways to open the door with a lever handle. You can use your hand, but you can also use your elbow, your foot, or a towel. The simple extension allows many users to find many ways to open the door. If you can't open the door you don't have access. The Ironmonger Portfolio Series of lever handles tries to take the door handle to a new level by incorporating signage, Braille, and other information into the door handle design. Everyone touches the door lever and it's located at just the right height to include other information. Johannes Potente's 'Handflatter,' designed in 1953, set standards that are still relevant. Design should be blind to culture, age, gender, and ability.
