The concept of "point-and-click" interaction transformed computing from text-based command lines into the intuitive Graphical User Interfaces (GUI) we use today. This shift required users to develop a new cognitive map linking hand movement to digital action.

Early researchers at Xerox PARC found that the speed and accuracy of target selection (modeled by Fitts's Law) were critical metrics for productivity. Training your precision in a grid environment directly correlates to the efficiency of professional software navigation.
