Before the mouse
, there was the trackball
. Built for DATAR in 1952, DATAR
turned out to be a complete failure. The next user interface device that used a ball was the mouse at Xeroc Parc
in 1972. Trackballs are a dying breed
of interface devices. But sometimes a trackball just seems more natural choice
for certain applications
- not so obvious
. Would you sit on one?
