seminar 2 notes

Chapter 11 discusses prototyping and mentions the two classes of prototypes, low-Fidelity and high-Fidelity prototyping and mentions several advantages and disadvantages with them. Obviously, low-Fidelity prototyping is much easier and faster and can demonstrate conceptual ideas without big problems. High-fidelity prototyping becomes only relevant when you’re in a stage where you want to test that the details are well-formed and integrated in the design.

The chapter also mentions scenarios and storyboards, which really are just detailed scenarios where the user’s interaction with the device is narrated. Although it’s good to imagine how the user may interact with the device in a given context, i feel like this technique suffers from the fact that the designers know everything about their design and may not easily comprehend what difficulties a real user may run into.

Question: What is actually a mood board??

In chapter 13 the authors present us with the evaluation framework DECIDE. Most of it are general instructions like “Determine the goals”, “Explore the questions” etc.

In chapter 14 the authors mention different types of evaluation studies, Usability testing and field studies. The difference between them is that the first one is conducted in a controlled lab environment while the second one is done in the wild.

Which one to choose depends on what the product is. For evaluating a new computer or mobile phone it makes sense to do it in a lab where you could for example extract information through eye tracking. But if you want to evaluate a product that is highly integrated in some outer environment, field studies should be conducted. Although it could be complemented with some usability tests too.
