Argumentation Systems are reasoning systems that provide automaticcomputation of arguments. ?Argument Assistant Systems? are graphic-orientedtools for supporting end-users to manipulate arguments. Recently, the novelfamily of ?Hybrid Argumentation Systems? (HAS) has emerged, combining thesetwo approaches. Even when some HAS have been presented, either they show inthe interface only final results of the computation of the dispute situation underconsideration, or have not explicit considered usability features focused on realfinal users. Besides, current semantic goes from the definition of theoreticalconsiderations to the graphical representation of the dispute situation underconsideration, avoiding the direct manipulation of arguments is a graphicalfashion. This paper discusses lessons learned at the development of DeLP Client,a particular HAS software oriented towards end-users where main goals includegoing beyond the above limitations. To achieve usability goals, some usability-oriented design guidelines recently proposed for the argumentation systemsdomain are considered.
