For people with impaired vision, canes can act as a symbol to alert others to their condition. This can be especially useful when crossing a road or in crowded areas to make drivers and pedestrians aware that the person may not see them accurately or at all, and may need to move out of their way.
There are three main types of canes used by people with visual impairment. People with low vision may use an identification cane to help them check the height of stairs, or any changes in the ground level to prevent trips and falls. Alternatively, they may use a support cane to provide stability when walking as well as identify differing floor surfaces. Thirdly, long canes are used for people with reduced or no vision. These lightweight, foldable canes allow the user to be one step ahead, assisting them to identify any obstacles or hazards before they reach them. They improve orientation, posture, confidence and safety. They help give the user feedback about their environment without having to feel the ground with their feet or look down to check the floor surface.
Training:
The Guide Dog Association in each state provides training on how to use the canes and assistance in selecting the most appropriate type of cane for the individual. There are a number of techniques that are taught for use in different settings.
Different tips can be used on the end of the cane, depending on what the user prefers and the type of activities they participate in. Generally a rural tip makes it easier to determine textures than a pencil tip, and doesn’t get caught on uneven surfaces or crevices as easily.
