The Surprising Origins of the Mouse Wheel

The Surprising Origins of the Mouse Wheel

A mouse wheel is not just a computer scroll button. The term also describes ancient mechanical devices like the hamster wheel, the industrial treadmill, and the treadwheel used for heavy lifting.

Long before we used our fingers to scroll through web pages, these circular frames were essential power sources. Ancient treadwheels used human or animal weight to lift heavy building materials, while the treadmill was once a harsh tool for prison labor. It is fascinating how the same design evolved from a literal engine of physical labor into a tiny plastic tool for our daily digital browsing.
