Abstract:
Learning Objects – LOs – were devised in order to cut down on production costs and time, as well as to facilitate the distribution and reuse of didactic contents by means of a series of functions, such as reutilization, traceability, interoperability, durability and easy editing. Our main objective in the present paper is to propose an interface environment for LO search and pre-visualization. The distinctive feature of such environment is both the easy access to all search refinement functions available, thus allowing users to fulfil their search objectives without requiring much cognitive effort, and the well-structured LO pre-visualization. We started the project by defining a set of criteria to assess LO research and solutions, and one of such works was used as our starting point for the interface environment. Our theoretical foundation relies on HCI (Human-Computer Interaction), and the major outcome of the present project is a nonfunctional prototype (in storyboard) of the inte
rface environment proposed, which in turn solves the majority of the problems we came across when revising the pertinent literature.
