Current desktop environments provide weak support for
carrying out complex user-oriented tasks. Although individual
applications are becoming increasingly sophisticated and featurerich,
users must map their high-level goals to the low-level operational
vocabulary of applications, and deal with a myriad of routine
tasks (such as keeping up with email, keeping calendars and
web sites up-to-date, etc.). An alternative vision is that of a personal
cognitive assistant. Like a good secretary, such an assistant
would help users accomplish their high-level goals, coordinating
the use of multiple applications, automatically handling routine
tasks, and, most importantly, adapting to the individual needs of a
user over time. In this paper we describe the architecture and its
implementation for a personal cognitive assistant called RADAR.
Key features include (a) extensibility through the use of a plug-in
agent architecture (b) transparent integration with legacy applications
and data of today’s desktop environments, and (c) extensive
use of learning so that the environment adapts to the individual
user over time.
