Final answer:
Unpredictability would be least likely to be considered a common aspect of experience design, as it can lead to confusion and frustration for users.
Step-by-step explanation:
In the context of experience design, factors that are commonly considered include usability, accessibility, and visual appeal. However, a factor that would be least likely to be considered a common aspect of experience design would be unpredictability. Experience designers aim to create enjoyable and meaningful interactions, and unpredictability can often lead to confusion or frustration for users.
For example, in a website or app design, users expect certain actions to lead to specific outcomes. If these actions produce unpredictable results, it can disrupt the user's experience and make the design less effective.
Thus, unpredictability would not be seen as a common aspect of experience design as it goes against the goal of creating a positive and user-friendly experience.
