Question:

Apply the design principles of consistency, affordance, visibility, feedback, constraints, mapping from Section 1.6 from Rogers/Sharp/Preece book and Normans book to Deep Fryer.

Choose any existing Deep Fryer. It can have a simple or complex user interface. Include one or more screenshots or sketches to clearly show the product.

• For each design principle in Section 1.6, provide a concrete example of how the software or products UI supports that principle? Do this by referring to specific things on that picture. Be sure to justify why you are saying that the example supports that principle (3- 5 sentences per principle). If nothing about your UI at all supports a design principle you might have to write justification, why the principles are unsatisfied?
