Task Analysis: to identify the tasks the potential users will perform, and in what order.

3. Heuristic Evaluation: Consolidate your findings from your user and task analysis and

propose a design and specify system requirements to realise the recommended interface. For

example, the number of items to display, the screen size, what colours, how many different

screens to display, the devices to you, the physical design.

4. Low-Fidelity Prototype: Develop a low-fidelity (paper) prototype (a minimum of 4

screens). Based on the above requirements, develop a preliminary design of the user interface.

At this stage, the prototype is basically a medium to support your initial concept and ideas. For

example, the prototype should show where the relevant button locations, how much information

would be presented on each screen etc. Low- fidelity prototyping is mainly to allow designers

to produce alternative designs expediently without having to go into depth or functionality.

Think of low-fidelity prototyping as the 5D tool for: design, draft, decide, discard and do-over.

5. Feedback and Survey: Perform an interim evaluation of your design by creating a method

of feedback and asking 3-4 potential users (e.g. friends, family members, classmates, etc.) to

complete the feedback for your low-fidelity paper prototype. Carry out the evaluation according

to prescribed methods found in the textbook (Shneiderman & Plaisant, 2017) or from other

scholarly sources.
