Resumen
The field of human-computer interaction (HCI) came into being more than 25 years ago with the mission of understanding the relationship between humans and computers, often with an eye toward improving the technology's design. But that relationship has since been altered so radically -- changes in the sociotechnical landscape have been so great that -- many in the community of HCI researchers and practitioners are questioning where the field is headed. HCI was mainly a scientific and engineering endeavor, using techniques derived from cognitive psychology and human-factors engineering. During the 1990s, the objectives of HCI began changing along with the growth of communication networks that link computers. Despite the progress, gradual but now very visible transformations in people's relationship to computers are leading many in HCI to urge a radical rethinking of the underpinnings of HCI: its mission, goals, and philosophical approach, both for research and practice.
