Abstract:
We have come to regard the human user, manipulating
physical input devices as the sole driver of interaction in
the graphical workspace. It is conceivable that for a vari
ety of applications, such as help and tutorial systems,
macro-by-example systems, session-playback systems and
in collaborative work, we may require an alternative agent
to perform tasks on the workspace, alongside the user. In
this paper we describe a relatively non-intrusive and porta
ble scheme for supporting such "synthesized interaction"
on the X window system, and illustrate how toolkits may
be instrumented to cooperate with such an agent at runt
ime, by providing information about the location of
objects in their interfaces. In particular we describe the
integration of synthesized interaction in the Artkit toolkit,
which is structurally similar to most modern toolkits and
should serve as relevant example.
Keywords:
