BD-UIMS:How It Supports Semantic Feedback and Direct Manipulation

In this paper we present some results from our research on representation methods and architectural model of UIMS, suitable for accommodating various interactive styles. By roughly describing an experi- mental system of BD-UIMS, we lay emphasis on how to support direct manipulation and semantic feedback. Particular attention is given to a simple conceptual model of user interface as well. Based on this model, the designing process of user interface is rather easy. Although current work is under DOS environm…
