What is a disadvantage of using visual scenes in AAC?

Using visual scenes in Augmentative and Alternative Communication (AAC) devices presents a notable disadvantage in that they can be difficult to understand without context. Visual scenes typically consist of images that represent a location, activity, or situation. While these scenes can effectively convey meaning in the right context, their interpretation heavily relies on the user's familiarity with that specific environment or scenario. Without context, a user might struggle to derive the correct meaning or intent from the visual, which can hinder communication effectiveness.

This issue emphasizes the importance of ensuring that users have the knowledge and understanding of the environment or situation depicted. In contrast, other elements, such as portability or reliance on advanced technology, do not inherently limit the understanding or accessibility of visual scenes in the same way that context-dependent visuals do.
