Task 4.1: Evaluation of existing systems for the realization of UIs

months 1-6 (5,4 man-months) D1: report about evaluation

Mainstream UI visual design resource based code generation

Example tools: Visual C++, J++, ... Shift towards “model-based / task-

based” (ref. CADUI’99) for “administrative GUI” applications Direct manipulation? Multimedia? Embedded systems???
