This paper describes a new approach for creating and using
identification keys based on two main components: the Open Key Editor
and the Open Key Player, both of which were created within the European
project KeyToNature. The Open Key Editor can be used to produce custom
identification keys starting from a master key and to add original usergenerated
content, while the most important feature of the Open Key Player is
the possibility to track relevant user activities into an eLearning environment,
in order to collect data to improve the design and usability of identification
keys.
