Why Technology Loves Rounded Rectangles: They're Easier on the Eye

Ever wonder why so many tech gadgets, OS windows and images all have rounded corners?  It may be more than just visual appeal.  The rounded corners may make things easier on the eye!

Nänni confirmed my theory: “You are absolutely right. A rectangle with sharp edges takes indeed a little bit more cognitive visible effort than for example an ellipse of the same size. Our “fovea-eye” is even faster in recording a circle. Edges involve additional neuronal image tools. The process is therefore slowed down.”

Professor Nänni is saying that rounded rectangles are literally easier on the eye. Put another way, compared to square-edged rectangles, rounded rectangles are more computationally efficient for the human brain. To me, this is a revelation. An idea that at the very least demands more investigation.

Oh how ridiculous. The corners are rounded because rounded corners are harder to chip than pointy ones.

Did someone get another one of those stupidity grants?
