  • The aim of activity-based computing is precisely to help users to manage the
    complex set of actions, tools, materials, resources, and people involved in an
    activity by introducing an explicit representation of the activity into the computer
    system.
  • The principle of activity-centered resource aggregation simply states that activity-based computing needs to support this bundling of relevant resources and services. In hospitals where a great number of electronic medical systems are used, a given activity might, for example, encompass the electronic patient record (EPR), access to lab request applications, medical images, lab results, medical observations such as blood pressure, etc.
    These services and resources may come from many different sources but all are
    part of a single activity, which is what gives them meaning to the clinicians
    involved.
  • In activity-based computing,
    the term “activity awareness” denotes the principle that the computer system
    maintains information about the users’ real-world activities.
    This awareness is used to give the user easy access to appropriate resources and tools. Links
    between particular activities and work contexts can be created to facilitate
    resumption of relevant activities.
  • In this article we have presented the principles, design, and evaluation of
    activity-based computing support for hospital work. The principles of activity-based
    computing have emerged through ongoing collaboration with clinicians
    working in large hospitals. Studies and design sessions with these clinicians
    pointed to a set of challenges associated with the use of computers in hospital
    work.
