Human computer interaction has evolved from studying one person using one computer, to individuals and groups collaborating with others in a variety of roles. To support our working lives, and our lives beyond work, we all undertake a wide range of activities, using a diverse set of technological devices, for numerous purposes. With these changes in the use of computers have come changes in design goals, from a narrow definition of ‘ease of use’ to enjoyment, from empowerment to enablement, and from convenience to attractiveness. In response to these changes HCI researchers and practitioners have developed new research foci and methods, and new design and evaluation methods to understand, create, develop and evaluate interactive computing technologies in their rich variety of forms, uses, and contexts. The activities that now need to be understood and supported by design include multiple and collaborative tasks. They do not always have single, clear goals, they often lack discrete start and end points, and sometimes the multiple goals are incompatible. Tasks are frequently carried out in parallel, with various levels of interleaving and interruption. People perform the same task with the same technological support in different ways, depending upon their social context, and the degree of cooperation and collaboration. Collaboration introduces overheads for managing the collaboration, which have to be traded off against gains in efficiency of the task itself.
