Abstract:
A model-based user interface environment refers to a runtime environment
which contains meta-knowledge about an application and its connection to
the interface presented to the user. We capture in our application
model actions which can be invoked by users, their operational
constraints, and data objects on which these actions operate. We capture
in our interface model interface components, actions which users
apply to these interface components, and operational constraints on these
actions. We then capture the mappings from the application model to the
interface model as a way to construct an interface to an application.
The modeling components used in the application and interface models are
active at runtime, and are the key which drives the runtime architecture
to support intelligent behavior such as partially automatic control
sequencing, automatic generation of textual and animated help, and
recordings of statistical and chronological command usage history. Also,
the modeling components used are task-oriented; specifying an interface
through these components eliminates the low-level programming from the
user interface creation process.
