Beautiful Users: Designing for People, organized by the Cooper Hewitt, Smithsonian Design Museum, featured nearly 100 objects illustrating the evolution of “user-centered design” — from the mid–20th-century work of Henry Dreyfuss (who coined the phrase “designing for people”) to the complex systems and services that today’s designers continue to develop.

The exhibition included, but was not limited to:

• Examples of the Human-scale measurement system, which aids in design for children, the elderly, the differently abled, and people of diverse height

• Objects designed for comfort and function, ranging from Dreyfuss’ Princess telephone to Amos Winter’s Leveraged Freedom wheelchair

• Diller Scofidio + Renfro’s Roomba Cam, which repurposes the household gadget for surveillance purposes
