The process of exploring is an important aspect of a user's general understanding of the environment they are navigating through in computational systems. The research outlined in this paper briefly presents an empirical study of user exploratory behaviour within the web context. It outlines the development of an exploratory grid obtained from this study and its use in forming the DIANE nx task model, enabling user interface and web designers to model users' exploration. Need for a New

Considering the abilities of various models and the context in which the exploratory task model will be used, the DIANE+ formalism was chosen for its very powerful, formal representation of a task, rich graphics notations and high usability for modelling and communication [6] . The DIANE+ formalism was analysed against the exploratory grid. This indicated where DIANE+ lacked in its ability to model task exploration. The following two issues arose when modelling forward and backward tracking behaviours using DIANE+. Linear Representation. Large navigational tasks will produce a long linear model.
