What is "three-dimensional mapping" in mobility?

Three-dimensional mapping in mobility refers to the cognitive process of creating a mental representation of an environment’s layout. This involves understanding the spatial relationships between various elements in an environment, which can significantly enhance a person’s ability to navigate effectively.

By visualizing the environment in three dimensions, individuals can better anticipate obstacles, plan routes, and improve their overall mobility skills. This mental mapping is particularly important for individuals with visual impairments as it allows them to conceptually "see" the space around them, which aids in orientation and navigation.

The other options, while relevant to mobility, do not capture the essence of three-dimensional mapping. Drawing maps on paper focuses merely on the graphical representation rather than the cognitive process. Using apps to navigate urban environments emphasizes technology over mental mapping. Lastly, physical training for navigating steps addresses physical skills rather than the cognitive understanding of the environment's layout.
