Distinctive and predictable smells in the urban environment can work as useful landmarks
From fish to fried chicken people with sight loss use all sorts of smells as navigational cues. Like any other landmark for a smell to be useful it has to be predictable.
Implications:
Smell is a useful and effective way for some people with sight loss to absorb information about their environment.
Opportunities:
There may be ways to use smell more widely as a navigational indicator.
