Landmark correct answers Object, sound, odors, temperatures, tactile or visual clues that are
easily recognized, are constant, and have discrete, permeant locations in the environment that can
give a traveler unique, specific information about the individual's location in space.
Primary landmark: correct answers An environmental feature that is detectable to visually
impaired travelers, that is ALWAYS present, and is NOT likely to be missed as one travels a
route (i.e. cane will come in contact).
Secondary Landmark: correct answers Any environmental that is INTERMITTENT or that may
not be encountered by travelers as they travel a route. (i.e. a fan in a water fountain or an object
on the sidewalk opposite of the traveler)
, Information point: correct answers A feature of a travel environment that by itself does not
convey specific information about a traveler's location in space, but when juxtaposed with other
features permits travelers to locate themselves relative to their surroundings.
Primary information point: correct answers traveler can locate themselves relative to their
surroundings.
secondary information point: correct answers any environment that is intermittent or that may be
encountered by travelers as they travel route.
Cue correct answers critical objects or sounds emitted from those objects that trigger an instant
recognition of one's location. Cues are not always present but when they are you know where
you are like a basketball bouncing. (aka primary information point)
clue correct answers Any auditory, olfactory, tactile (including temperature) kinesthetic, or visual
stimulus affecting the senses which can be readily converted to give the traveler information
necessary to determine his position or a line of direction. Clue is not unique to an area
information point can be like a landmark but (i.e a water fountain if there are more than one in a
hallway) (aka secondary information point).
Primary Landmark example correct answers on a route there is a large landscape design in
middle of sidewalk with flowers inside. The traveler always contacts this landmark for it is
permanent, unique and easily found for his cane come in contact with it each time he travels the
route. It is the only landscape flower arrangement on the entire route and the traveler must move
around it in order to continue his way.
Secondary landmark example correct answers there is a bench that is unique to this route.
However, the traveler does not always encounter this bench. It is off the sidewalk just enough
that his cane only contacts the bench if he is Shorelining or close to the right side. Sometimes he
contacts this landmark and sometimes he does not and therefore it is a secondary and mark.
Because this is the only bench on this route it is unique, and it never moves therefore it is
permanent, it is easily found for a low vision traveler but only easily found by a blind cane
