This research investigates the possibility of designing active behaviour stimuli for websites users. Since hypermedia need the users actions chain to communicate, this dissertation argues that hypermedia products can be configurated to carry, within themselves, the elements that stimulate, guide and interconnect the users actions. This dissertation reflects upon new approaches of the relation between the design product and its user - approaches that are based in the concepts of experience design and emotional design, which are understood, within this research, primarily as consequence of new demands of the contemporary design practice and theory. The idea of engagement is developed as translation of interactivity dynamics and requires topics on motivation, strangement and involvement. Projects that stimulate the audience action can be identified in the histories of Art and Design. From these projects, this research recognized patterns that can also be recognized in websites. The main aspects of these patterns are categorized as conceptual elements that envisage to orient the engagement dynamics within hypermedia.
