ABSTRACT
Many technological approaches have been proposed during recent years to transform the personal computer (PC) and make it usable in new places and situations. As computer use spreads to novel situations and locations, as well as begins to support activities currently not supported by conventional computers, they will have an even greater impact on everyday life. Continuous access to devices that provide enhanced communication and information processing functionality will change the environment in which we live as the devices influence the way we communicate and interact socially. While the approaches to transform PCs differ from each other, not only in their view of how computers should be designed, but also in how they imply different use and relationship to computers, they, in one sense, promise the same thing: to free the user from the boundaries of the desktop and the limitations of the desktop computer interfaces.
