multidevice configuration work and work-space
aggregation into a personal ad hoc smart space for
knowledge workers. The main goal of ActivityDesk is
to reduce the configuration work required to use
multiple devices simultaneously by using an interactive desk as an activity-centered configuration space.
Through ActivityDesk a shared work space across
devices can be set up in a tangible and visible way,
after which information is automatically distributed
across all participating devices.
Based on our research on ABC and the design of dif-
ferent activity-centered systems we are able to derive
some common findings. While ABC has been shown
to be particularly advantageous in certain settings,
there are still several recurring questions that remain
unanswered. In this section we provide an overview
of our main findings so far and the open issues that
will need to be addressed in future work.
Over the many research projects, the core idea of
activity-centered computing has proven to be
extremely robust; significant improvements in
human-computer interaction are achieved by allowing users to organize computational resources into
logical bundles of activities, which can be subject to
distribution, sharing, adaptation, and suspension
Users found computational activities a useful construct to organize information and communication
processes. They reported being more focused and
appreciated the ability to switch quickly between different information contexts. In desktop environments, we observed that users generally closed fewer

This original project (Bardram 2009) focused on supporting mobile and collaborative workflows in hospitals using activity as an organizational unit to structure patient data.
