CPS 4601/5951 Spring 2018 Homework #2-Usability: design principles Name Due: Thursday, January 26, 2018, turned in during class. No late homework Your goal is to apply the design principles of visibility, feedback, constraints, consistency, and affordance to an existing piece of software Select any software that already existed by December 31. Preferably something you have helped to write (eg, for a class or work), but commercial or open source software is ok too. It can have a very simple (eg, just ASCII Q and A) or very complex user interface Include one or more screenshots or sketches to be referred to below (50) For each design principle listed above, provide a concrete example of how the software's Ul supports that principle, Do this by referring to specific things on that picture. Be sure to iustify why you are saying that the example supports that principle (3-5 sentences per principle). (If nothing about your Ul at all supports a design principle, you can say so, but you might have to write a lot more to justify that.) (50) For each design principle, provide a concrete example of how the software violates that principle (with screenshot, justification, etc., as above). (If nothing about your UI at all violates a design principle, you can say so, but you might have to write a lot more to justify that.) Here are the things considered while grading 1) The assignment requires examples for all the 5 design principles for full credit 2) Graded on a total of 100 points, with 50 for providing examples of how the software's Ul supports these 5 principles and 50 for how the software violates the same (i.e. 10 points per example) 3) It is necessary for you to provide concrete examples of how the software violates and supports the principle to get full credit. If the example doesn't clearly explain the violation of the design principle or if it does not explain how the software supports the design principle no credit is allotted
