Understand the key concepts concerned with modelling.

Explain why and how models are used in interactive systems design.

Explain why user-centred requirements modelling is more effective for interaction design than traditional methods.

Describe several user-centred techniques that can be used to capture user requirements (e.g., Soft Systems Methodology & participatory design).

Explain what is meant by a cognitive user model, give an overview of the range of models available and indicate the usefulness of such models

Distinguish between the high-level (GOMs) and low-level (KLM) cognitive models.

Produce GOMs and KLM analyses of simple user tasks.

Show how GOMs and KLM can be used to analyse an existing system or proposed design.
