				Undo as concurrent inverse in group editorsChengzheng SunUndo is a standard feature in most single-user interactive applications. The user can use undo to recover from erroneous operations, to learn system features by trial and error, and to explore alternative solutions by backtracking. The availability of undo in multi-user collaborative applications is particularly valuable because: (1) features…

				Rainbow usabilityDiane NortonThe March-April 2002 interactions Whiteboard column caught my eye. Focusing on usability terminology, the article declares that a product's intuitiveness depends on its users' previous life experience and learning. "Aha!" I thought. "This sounds like mental models."

				Advancing UCD while facing challenges working from offshorePradeep HenryIndia develops a substantial percentage of the world's software. Hundreds of software companies in India do software development work for various clients, including organizations in North America and Europe. Although it is accepted that Indian programmers are skilled, would users say that the best interfaces come from India? Hardly…

				Using HCI to leverage communication technologyGary MarsdenWhat is the benefit of human-computer interaction (HCI) to a developing country? On a continent where an estimated one in 130 people has access to a personal computer (PC) [3], surely interface design is an irrelevant luxury? On the contrary. Precisely because access to information and communication technology (ICT)…

				Enabling computer interaction in the indigenous languages of South AfricaLaurette Pretorius, Sonja BoschIntroduction Ubiquitous computing, the Web, and the ever-increasing processing power of computers have made the study of human-computer interaction (HCI) and the design of intelligent human-computer interfaces fields of crucial importance. If we further assume a human-centered approach to interface and systems design, then human preferences for modality of…

				Cultures, literacy, and the webMarion Walton, Vera VukovicWhen discussing how people get the "scent" of information on the Web, and thus how best to design for them, we seldom consider the role of literacy. Literacy, in its broadest sense, is not a neat parcel of skills easily packaged and given to someone. Anthropologists have found that…

The other was to enable the Brazilian IT industry to compete in a globalized world in…

				HCI in the so-called developing worldDerrick CogburnAll around us, information, knowledge, and the use of networked computing continues to revolutionize how we live, work, and play. Although this perspective is obvious to many of us and in danger of becoming hackneyed, important structural changes are indeed occurring. Driven by social, political, economic, and technological factors,…

				Universal, ubiquitous, user-interface design for the disabled and elderlyAaron MarcusIntroduction How many of you have friends or relatives who are seriously disabled or elderly?
