A simple, thoroughly user-friendly design: this was the initial commitment for the PlayStation®. Starting from scratch, the developers applied bold thinking to create a design that also embodies high performance. The design chosen is based on elementary shapes and a clean image, in a console that is slim, compact, and attractive in most living rooms. For the controller, after many prototypes and refinements on a scale of millimeters, the shape ultimately used is one that feels comfortable no matter how small or large one's hands are. Control buttons are uniformly round, making them easy to press from any direction.
