Using and creating prototypes for effective communication of design ideas in a development project and specification of features & interaction. For Hi-fidelity prototyping you may want to look at the Pencil prototyping software.
Lecture slides on user interface evaluation with cognitive walkthrough. It is recommended that the evaluation of the user interfaces created in the assignments contain a cognitive walkthrough analysis of the critical interaction/navigation path.
Cognitive walkthrough is based on modelling users' thinking structures and concepts that the user is familiar with. A cognitive walkthrough of a user interface consists of the definition of interaction steps (user's decision making points and actions) and the review of following questions at each step:
Question 1: Will
the users be trying to produce whatever effect the action has?
Question 2: Will users
be able to notice that the correct action is available?
Question 3: Once users
find the correct action at the interface, will they know that it is the right one for the effect they are trying to
Question 4: After the
action is taken, will users understand the feedback they get?
