Interactive technologies in museums enhance the visit experienceby providing contextual information and fostering collaborationand participation. In this paper we revisit the design of theubiquitous transparent exhibition case from a museum learningperspective. Transparent cases with interactive properties cancomplement other museum technologies and mitigate some oftheir shortcomings, such as the group isolation caused by audioguides and mobile devices. This paper focuses on the design ofinteractive cases and makes three contributions. First, based onfield observations and interviews we present a list of requirementsfor interactive cases. Second, we propose a design space withdimensions grouped around the themes of hardware, interactionand information design. Our design space suggests interactivecases which present collocated information at increasing levels ofdetail, facilitate social interaction, and integrate with othertechnologies. Third, we demonstrate our design space throughsample case designs and discuss the general technical challenges.
