Building Environments for EUD: a Model-based
Approach
Abstract
End-User Development (EUD) and tailoring is
characterized by several phenomena, which have been studied separately and separately
faced in the development of EUD environments. A recently proposed model of HCI
is used to study these phenomena in a unique frame. This model recognizes explicitly
that each message in an interaction process is subject to two interpretations,
one performed by the human and one performed by the machine according to the
programs embedded in it. The closer are the two interpretations the more usable
is the system by the human. Starting from these premises, a bottom-up approach
(from observation to theory) to the development software environments designed
to support various activities of EUD is illustrated. The approach requires users
to directly collaborate to the system design and to the tailoring process to
balance the effects of the phenomena. The strategy is illustrated, outlining
its implementation through web-based prototypes.
