What is an example of a fixed tactile cue?

A fixed tactile cue is a physical reference point that conveys information through touch and is consistent in its location and form. Tactile paving serves as a prime example of a fixed tactile cue, as it is specifically designed to provide a tactile feedback mechanism for individuals with vision impairments. These paving blocks have a textured surface that can be felt underfoot or through a mobility device, guiding individuals along a path or alerting them to important locations, such as street crossings or station entrances.

In contrast, sounds of traffic, shifting sidewalk textures, and changing traffic signals involve variables that can change in positioning or occurrence and do not provide a consistent, stable reference point for navigation. Sound cues, while helpful, are auditory and do not rely on tactile information. Shifting sidewalk textures and changing traffic signals both refer to elements that may vary over time or location, which undermines their effectiveness as fixed cues. Therefore, tactile paving stands out as the only option that aligns with the concept of a fixed tactile cue.
