The article by Mark Weiser discusses the emerging field of ubiquitous computing, which aims to make computers invisible to users by integrating them into everyday environments. Weiser outlines the challenges and opportunities in this field, emphasizing the need for new computer science research. The article covers various aspects of ubiquitous computing, including hardware components, network protocols, interaction substrates, applications, privacy, and computational methods. Key examples include the Liveboard, Tab, and Pad prototypes, which are designed to be small, low-power, and easily integrated into daily life. The author also highlights the importance of addressing privacy concerns, such as preserving the privacy of location data. The article concludes by discussing the potential for ubiquitous computing to revolutionize office environments, particularly in energy management and environmental control.The article by Mark Weiser discusses the emerging field of ubiquitous computing, which aims to make computers invisible to users by integrating them into everyday environments.
