End-user computing requires that end-users trust the system and the results obtained by its use. The approach we have elaborated at the Pictorial Computing Laboratory of the University of Rome La Sapienza is the result of several experiments through the years in design and use of end- user visual computing systems and is aimed at improving the system trustworthiness. To this end, our approach adopts the notation developed by the users in their working environment as the kernel for the Visual Language used during human-computer interaction, supports users while navigating in the virtual space by establishing a system of cornerstones, within a scaffold, and provides control on the system to trap user slips and errors. The paper reports and discusses some results from our experience in the design and use of end-users visual environments.
