What is the purpose of trailing in mobility?

Trailing in mobility refers to the technique where a person follows a travel line by maintaining a consistent position relative to a guide or surface, often using their cane or another mobility aid. The primary purpose of trailing is to help individuals with visual impairments maintain a straight line of travel, ensuring they can navigate their environment effectively without veering off course. By utilizing surfaces such as walls, railings, or curbs, individuals can gather spatial information and orient themselves, thereby enabling them to move confidently in a straight direction.

This technique is especially useful in environments that require precise navigation and is a fundamental skill taught to individuals learning how to move through various settings while relying on tactile feedback. Maintaining a straight line of travel is essential for safety and efficient mobility, making trailing a significant component of mobility training for those with visual impairments.
