The lessоn оn prоtotyping provides multiple different spectrа for clаssifying prototypes. In this question, you will define these, then evаluate a prototype for how it aligns to these spectra. First, define fidelity as a concept for classifying prototypes. Make sure your answer describes the difference between low and high fidelity prototypes. Second, define evaluation as a concept for classifying prototypes. Make sure your answer describes the difference between evaluating function and performance. Third, define scope as a concept for classifying prototypes. Make sure your answer describes the difference between evaluating horizontal prototypes and vertical prototypes. Finally, consider the prototype description below. Classify this prototype description according to the spectra above. Is it a low or high fidelity prototype, and why do you think so? Is it evaluating function, interface, or performance, and why do you think so? Is it a horizontal or vertical prototype, and why do you think so? The designers of Canvas are prototyping a new way to structure the class page as a whole. They do this with a one-page, static, clean mockup that shows the new layout of the course calendar (in the top right), the student’s course to-do list (in the bottom right), and a new hierarchical menu for navigation on the left. In presenting this prototype to potential users, the designers ask questions like: Where would you go to check an assignment due date? Where would you go to view upcoming events?
