Question 6

Describe one major difference between high-fidelity and low-fidelity prototyping.

Answer 6

One major difference between high-fidelity and low-fidelity prototyping is that in the latter you’re designing, while in the former you’re programming. When you’re designing, you need the freedom to generate and consider alternative designs, and high-fidelity prototyping environments often constrain design creativity.
