Beyond the desktop metaphor
As an extension of the self, the avatar—a familiar concept from the world of computer games—could become a new paradigm for operating system interfaces. Three tendencies may contribute to this paradigm shift. First, computers are becoming increasingly mobile. Not only are laptops outselling desktops, they are also becoming smaller and lighter. Second, computers are becoming more ubiquitous: computer operating systems are increasingly powering other devices as well, such as cell phones, PDAs and music players. Third, networks are becoming pervasive, allowing more communication between connected mobile computing devices.
