What is an important drawback of paper prototypes?

A notable drawback of paper prototypes is that they can be difficult to interpret, particularly for users who may not be familiar with the concepts being presented. Unlike digital prototypes, which can provide interactive elements and immediate visual feedback, paper prototypes often require users to rely on their imagination and interpretation of static images. This limitation can lead to misunderstandings regarding how the interface is meant to function or the experience it is trying to convey. Consequently, this can hinder the effectiveness of usability testing, as users may not engage with the prototype in the way intended by the designers, limiting the valuable feedback that can be gathered during testing sessions.

In contrast, the options suggesting that paper prototypes enable remote testing or collaboration may not accurately reflect the traditional use of paper prototypes, which are generally more suited to in-person interactions. As for visual appeal, paper prototypes are often rudimentary and may lack the engaging elements found in digital designs, making that choice less relevant when discussing drawbacks.
