I
Do Do It: Three Fundamentals of Cane Travel
by
Peggy Elliott
Peggy
Elliott and Michael Gosse walk together using their canes.
From the Editor: Peggy
Elliott is one of the best cane travelers I know. She is president of the Iowa
affiliate, second vice president of the National Federation of the Blind, and
a busy attorney and city council member in Grinnell, Iowa. All this means that
she gets lots of practice using her cane. In the following article she draws
from example and illustration to distill what some consider to be her rather
eccentric cane technique from three fundamental skills. In addition she throws
in a lot more good advice. If the test of successful cane travel is getting
where you want to go safely, gracefully, and efficiently, Peggy is among our
best travelers, and we should all pay close attention to her comments. This
is what she says:
I learned to use a white
cane a number of years ago under circumstances that would now be described as
discovery learning, but before that term was coined. I was taught the fundamental
cane technique of stepping and simultaneously tapping my cane in front of the
foot I wasn't stepping on and then stepping forward and repeating the simultaneous
tapping in front of the other foot at the other end of an arc no wider than
my shoulders. The technique is often called the two-point touch technique. I
was taught to center my cane by holding it with my index finger extended and
my thumb on top. The cane handle was to be kept near the center of my stomach.
I was then drilled with daily practice for about nine months to perfect the
skills of tapping, centering, staying in step, arcing widely enough, and trusting
the information my cane provided until these techniques became so routine that
I no longer needed to think about them and did them unconsciously.
Though
I no longer use these techniques routinely, I would absolutely teach a new cane
user exactly as I was taught in order to achieve the same result--unconscious
and casual reliance on the cane to tell the user information accurately and
rapidly enough to maintain safety. In short, I would encourage personalizing
the style of cane use only after the fundamentals have been mastered and internalized.
As
I say, I don't center, stay rigidly in step, or worry about a precise arc. And,
most important to me, I don't tap. Instead I slide the cane from side to side,
never lifting the tip off the ground. People have asked me over the years how
I was taught, what I now do, and why, usually in the context of discussing some
tidbit of cane use or orientation, and often at a big national convention hotel.
So I have decided to describe a few of the things I do in case they are useful
to others.
While
I learned cane travel in a Federation center, not everyone can, largely because
the rehab system still doesn't completely believe in our Federation approach.
But the Federation approach is not taught solely at such centers. Every chapter
meeting, every state convention, every encounter between two blind people can
be a context for teaching and learning the Federation approach to cane travel;
attending a center merely speeds the instruction and roots it firmly in the
mind and soul. But people who never attend a center can and do become fine and
safe cane travelers. The only requirements are commitment to learning and practice.
So
I have boiled down advanced cane use to several basic concepts. Mastery of these
concepts through practice allows anyone to become a safe and efficient cane
traveler. Good cane users could add lots of tips and tricks gleaned from daily
use, but I think these are the foundation. For true success in cane travel,
each must be mastered.
While
confidence in the Federation approach to cane travel and daily experience using
the cane are the strongest indicators of success in traveling competently as
a blind person, these are the three fundamental concepts I use regularly. None
was exactly taught me when I learned cane travel. In fact, some techniques I
now use are actually contrary to what I was taught. This is partly why I say
that confidence and experience are the strongest predictors of success in travel.
All successful blind travelers take what they are taught, formally and informally,
and create a successful personal style. Trying to travel exactly the way one
was taught yields constant nervousness for fear one may be doing things wrong
while preventing innovation using one's own strengths and observations.
Successful
cane travel seems impossible to the novice; it certainly did to me. Looking
back over many years of cane travel, I can say with certainty that, if I had
simply kept doing what I had been taught and traveled in familiar areas only,
I wouldn't be a good traveler today. Innovation and application of the techniques
in new situations have made me a much better traveler. Again, looking back,
I once thought successful travel as a blind person was a pleasant myth. Only
when I stepped out, white cane in hand, and began applying the techniques and
adapting them for myself did I find the goal reachable. I write these words
in the hope that others will dare to move into unfamiliar places and situations
and find the methods most congenial for them. Then, one day, these experimenters
can look back as I do and say that gradually, without noticing it, their style
has changed and their skills improved until they have achieved a comfort and
confidence they once thought possible only for others. In other words, it works!
Here
are the three fundamental concepts I use. Having mastered basic cane technique
and these three concepts, anyone can experiment, try new things, and spread
his or her wings. The key is to challenge oneself to improve. Here are three
ways to do it: mapping, reversing, and pathfinding.
Mapping
is the mental gathering and retention of information about an area that allows
the blind traveler to travel anywhere in it without other information except
that contained on the mental map. Everyone uses mapping to get around. By this,
I specifically mean sighted people. Sighted hunters have mental maps of the
terrain that leads to their favorite deer stand or pheasant nesting ground.
Sighted shoppers, familiar with a mall, plan their stops to avoid doubling back
without reference to any but their mental maps. Sighted drivers moving about
a familiar city rarely glance at street signs and navigate streets and freeways
by referring to their own mental maps along with a sense of accustomed distances
and observation of familiar landmarks.
When
blind people set out for a destination, why shouldn't they use the same techniques?
In fact, why should we not expect ourselves to make such maps for common daily
use just as sighted people do? Our maps may have different reference points
and landmarks, but they can be equally useful. In fact, since our maps use touch
and sound instead of visible landmarks, we can more easily convey them to one
another. We can of course use maps or directions from sighted people, but these
are often given in visual terms and require translation into tactile and audible
ones.
Many
blind travelers use this mapping technique when traveling outdoors along streets,
especially those set in a grid pattern. But, when it comes to buildings, some
of us think that mapping doesn't work or isn't worth the effort. It most certainly
does and is absolutely worth the effort.
Let
me give a few examples. I first began rigorously to develop this technique inside
buildings when traveling to NFB conventions. As soon as I reached my room and
shooed out the bell person, I would sit down on the corner of the nearest bed
and mentally go over the route from the desk to my room, rehearsing the route
until I could remember it flawlessly then mentally practicing the reverse, walking
back to the desk. As I traveled and practiced more, my ability to remember the
route became more and more routine, so I never sit on the corner of the bed
any more. By the time I get into my room, the practice of years has enabled
me to lock in the route so that I can call upon it as needed. I usually ask
a few questions at the hotel desk like the location of the restaurants, in order
to get those on my mental map right away. Then, as I move around the hotel,
I add details to the map for each floor. Here are a few examples from Federation
convention hotels.
At
the national convention hotel in Anaheim, I first stepped onto a floor with
smaller meeting rooms to go to a specific room. To reach it, I discovered that
one angled about forty-five degrees to the right after leaving the elevator
lobby and then straightened out to walk down a long hall in the same direction
as one had been going when leaving the elevator lobby. The angled digression
was necessary to go around a large open stair well and escalators. Meeting rooms
opened off this hall and also off hallways perpendicular to it branching to
the right. Later that day I arrived at the same floor looking for a different
room and discovered that, to find it, one angled forty-five degrees to the left
to reach a different hallway, down which one proceeded in the same direction
as one had been walking when leaving the elevator lobby. Rooms opened off this
hallway and off hallways branching from it to the left. While the distances
were long, the map of the floor was almost complete in my mind.
Still
later that day I was at the end of the left hall and needed to go to a room
at the end of the right hall. By then I knew that I could have returned all
the way to the elevator lobby, walked across to the right-hand hall, and walked
back up that hall to the room, since that day I had at different times already
walked each piece of this proposed route. However, my mental map also told me
that cross halls were very likely to connect the long left and right halls at
intervals, allowing people like me to cross between them without having to go
all the way back to the elevator lobby. I started looking for such a hall and
found one almost immediately, saving myself a two-block detour.
This
brings me to an important detail in mapping: which way is north? While I know
good blind travelers who rarely pay attention to the cardinal directions, I
am not one of them. When I enter a building that I'm going to use intensively,
I try as soon as possible to learn which way north is so that I can draw my
mental maps using north, south, east, and west rather than right and left, which
are obviously dependent on which way one is facing. I find that knowing where
north is allows me to make a map of a floor or lobby area that I can mentally
look down upon, locate myself upon, and determine my next move, whereas having
just rights and lefts requires constant transposition, depending on where one
is and where one is going. When I can't find someone who knows which way north
is, I simply assign what I call a "false north" (for example, the
direction one travels when leaving the elevator), so that I can still have a
consistent map that works throughout the hotel and is not reliant on rights
and lefts.
Once
in a state convention motel I had vague directions for the path from my room
to the first convention meeting. I discovered that the path included the entire
length of a parking lot, passing along the outside of the lobby and then meandering
among several other buildings before arriving at the one we were using. Once
I arrived at the first meeting, I reviewed the route several times in my head,
since indoors and out it was nearly three blocks long and one of the longer
routes I had walked in quite some time. By using north, estimating direction,
and drawing my mental map, I discovered that I had walked around three sides
of a very large square inside which were located various motel buildings.
I
began enquiring about going from my room on the very edge of the square across
the fourth side instead of traveling around the other three sides. At first
I was told that there was no way to do that, but other convention goers staying
down at the very end as I was eventually did discover that there was a way to
walk along the fourth side, which went off hotel property and then back onto
it. Finding that route earlier would have saved me a lot of walking.
Mapping
uses all the tactile and audible features of an area as landmarks. For example,
we Iowans quickly and to our delight discovered that, when walking along the
ballroom foyer that included all the entrances to the Louisville convention
ballroom, we could just keep walking until we stepped from carpet to tile. The
next door brought us into the convention hall just behind the Iowa section.
In large open spaces I always look for details like low walls, steps, potted
vegetation, changes from tile to carpet, and seating areas--details I can find
with my cane and use as landmarks or points at which to change direction.
Then
there are fountains. I used to hate them. Their constant sound can drown out
other information. Then I discovered their utility--a huge fixed point of navigation.
You don't have to go anywhere near a fountain to know where it is and to use
it as a navigation aid. I remember a state convention with a fountain in the
hotel lobby. I arrived at the banquet from one direction and left it in another,
heading for the lobby. Using my mental map, I chose a hallway I had never used
before, confident that it would lead toward the lobby and that I would be able
to tell exactly where I was as soon as I heard the fountain. The plan worked
just fine. In fact, my husband and I have a joke that goes, "The fountain
is our friend!" by which we mean that some people think fountains are noisy
when we think them useful.
When
I enter a building I have never been in before, I start gathering information,
including asking questions of both blind and sighted people. It's my job to
create my own map, and I get information in many ways and make it useful in
building my maps. With sighted people I usually point in the direction I think
they are indicating and ask if that's what they mean. Once I confirm the direction
they mean, I find my own tactile or audible method of getting there.
This
same technique works well in airports I use regularly. My own home airport and
the one I use most often to change planes, United in Chicago, are both laid
out in the shape of a huge print H, which allows me to know at all times both
where I am and how to walk to an objective. When the new Denver airport was
opened, my husband Doug went through it for a plane change before I did. He
came back, pleased that the Denver people had been accommodating enough to build
the long United corridor just like our street at home. When we walk out our
front door, which is on the side with odd numbers, larger numbers are to our
left. This exact pattern--odd-numbered gates on one side, even on the other,
and odd numbers arranged like our neighborhood street--makes it easy for us
to know from the single fact of the number of our arriving gate exactly which
way and on which side our departing gate is located.
Many
of us have a mental map of the Capitol Holiday Inn in Washington, and some of
us actually retain three or four maps of the ground floor, which has changed
over the years. The hotel manager told us last February that the ground floor
is changing again and gave a few examples. I encountered him three days later,
and he was astonished that I could repeat exactly what he had said. I would
have been disappointed in myself if I could not have done so. Having advance
notice of a change of map was a real treat. It counterbalanced just a little
all those times, especially in airports, when the map that once worked no longer
works due to construction.
This
leads me to a final tip about mapping. If the map is not working, don't junk
the technique; just revise the map. I was recently at a state convention, and
one element of my map just wasn't working--the orientation of the elevator on
one floor. Everything else worked just fine, but I could never reliably find
the elevator on that one floor. We left the hotel and returned, coming in a
different door, and I approached this elusive elevator from a different direction,
which allowed me to discover that I had one element of my map in the wrong place.
On one of the lower floors I had the orientation of the elevator spun ninety
degrees, facing south when it actually faced west. When the map isn't working,
keep revising, and it will eventually work.
Remember,
it's your job to gather the information and to make the map, not the job of
sighted people to know how to tell you where things are. In the first place
they don't think about tile and fountains and "north" the way we do.
In the second place blaming a sighted person for giving bad directions is no
different from blaming a bad cane travel teacher or bad genes for not finding
a place. The objective is to learn how to talk to all kinds of people and make
the map for yourself. Many blind people routinely do this every day, and most
of us can learn to do so.
The
other two fundamental concepts are actually specific ways of using and enhancing
the skill of mental mapping. I call the next one reversing. Reversing is the
ability to move unerringly from Point B to Point A along the route one has already
walked to get from Point A to Point B. The most common use for reversing is
in restaurants, although the skill is universally useful. In restaurants I want
to be able to walk to the front door from my table, both for leaving and for
finding the cash register, which is commonly by the front door. And I want to
be able to return to my table or to the front door from the rest room. In order
to do either, I have to be able to reverse a route I have just walked within
the last hour or two or the last ten minutes or so. In restaurants I frequent,
the need for this specific skill of reversing fades as an actual mental map
emerges. But I want to be able to move about in a restaurant I'm going to be
in only once. I use the same technique I use when going from a hotel check-in
desk to my room, paying attention to turns and other detail such as raised areas,
sources of music, changes in flooring, and changes in noise level.
Learning
the specific skill of reversing, like learning how to map, is something I made
myself do consciously so that the skill became second nature and takes very
little effort any more. At first it felt scary to stand up from a restaurant
table and start walking toward where I thought the door was. Gradually I learned
to pay attention on the way in so that I was no longer guessing on the way back
out.
Adding
the location of rest rooms is merely a further application of this skill. I
can get directions from a server or another diner to the rest room or follow
someone there the first time. I pay close attention to the route between the
table and the rest rooms. Once there, I can then return to the table by reversing.
Or, as sometimes happens, I can add together the two routes, one to the table
and the other to the rest room, to make a broader map, allowing me to go from
the rest room to the door, where the rest of the party is gathering. All this
takes much longer to explain than to do, and all this is easily performed by
any blind person who makes up his or her mind to do it. It starts with a determination
to develop the skill of reversing and the willingness to try.
The
third fundamental concept I use is pathfinding. I became convinced a long time
ago that I cannot walk a straight line. Neither can most other people, blind
or sighted. Take as an example the sport of orienteering. Sighted people take
two things with them into wild country and make a day of going from Point A
to Point B, using only these two things. One is a topographical map, and the
other is a compass. These orienteers are sighted, but they assume they can't
walk a straight line, so they use a compass as one of their two basic tools.
Well I can't walk a straight line either. It doesn't matter how carefully I
center my cane or standardize my stride. I drift off the straight line. I suspect
that this is true of most people and thus of most blind people.
Without
additional cues, over a distance anyone will walk at an angle. Sighted people
use curb lines and objects at a distance toward which they can navigate, so
they seem to walk straight. But send them orienteering, and they'll find out
about straight. Blind people don't have curbs at a distance beyond our cane
reach to parallel or objects in the distance toward which we can steer unless
we're lucky enough to be walking toward a constant noise source like a fountain
or a busy street. So I long ago concluded I would have to find auditory or tactile
alternatives to guide me in a straight line, and I developed what I call pathfinding.
This
was the basis for deciding not to tap my cane. I learned when starting to use
a cane to arc the cane from left to right and then back to the left again, tapping
at the outer edges of the arc. I used this method for a while and then figured
out I was missing all kinds of information by picking up the cane for most of
its trip across my path. I found that, by leaving the cane on the ground and
gliding it from edge to edge of the arc, I learned a great deal more about the
surface on which I was walking and could more reliably keep to a straight path.
The
information I acquire using the glide method includes the location of cracks
between sidewalk and parking lot, an important pathfinding device when walking
along a parking lot; seams in the sidewalk perpendicular to my path, which nonetheless
convey direction; and, most important, seams between sidewalk and street, which
are often composed of two different materials, also discernible more easily
using the glide technique. Using this method, I can detect slopes, both those
going across my path, which indicate driveways, and those going in my direction,
which indicate the approach of streets or alleys. I can find details in the
walking surface which help to identify other cues so that the walking surface
itself turns out to contain landmarks like the metal strip in the floor of the
east tower in Louisville which, when one crosses it going south, is a signal
to start drifting left to find the stairs up to the second floor. I think I
also find drop-offs and stairs more reliably when my cane never leaves the ground.
All
these changes I have made in my cane technique from the original arcing technique
I was taught have led me to make yet three more changes. The first is cane length.
I took an informal survey several years ago among people who seem to travel
well using a white cane. My survey was provoked by the comment I often receive
that my cane is too long. I must say here that I am really the only one who
can tell whether or not my cane is too long as long as I am not constantly tripping
others. I use a straight cane, meaning one that does not fold or telescope,
since I find that canes in sections, while they may be convenient to store,
always give me two kinds of information: that which I need and that which continuously
reminds me that I am using a segmented cane, which alters the information on
its way from the tip to my hand. I prefer to receive information about my surroundings
only and not to be reminded constantly that I have sections. The storage problems
people anticipate for such long canes (mine is sixty-five inches) are mostly
mythical in my experience, and, when the rare problem occurs, I think it's a
small price to pay for the purity of information I'm getting.
My
informal survey showed that most of my friends who travel confidently carry
canes that, when held vertically with the tip on the ground reach a point somewhere
between the user's chin and nose. Most of these people also use straight canes.
Mine is equal to my height. While every person must choose the cane length of
comfort, I do think that my informal survey indicates that good cane users typically
use longer canes. I know some fine cane travelers who don't use canes of that
length, and I always come back to the stipulation that the cane must be comfortable
and safe for the user. But I always urge people to try longer canes. I began
my cane use with a much shorter cane. As I grew in skill, I started buying longer
and longer canes. For one thing, I can always shorten the cane as needed by
holding it more nearly upright and lowering my hand along the shaft, sometimes
in crowds gliding my cane tip mere inches in front of my feet, while the handle
is by my cheek.
But
I cannot lengthen a shorter cane. For another, when I walk at speed, a longer
cane gives me another step's warning of obstacles in my path, an extra measure
of safety I appreciate when encountering drop-offs and obstructions, before
which I can stop well short of the object or flight of steps.
My
second change of technique was to abandon for most purposes the strict staying
in step and also to abandon the tapping technique. If I were teaching cane travel
to novices, as I mentioned previously, I would teach them to tap and stay in
step as a way of getting people to pay attention to what the cane is doing.
Later in their instruction I would encourage experimentation. Instead of swinging
and tapping my cane, I glide it frequently enough to pathfind and identify obstacles.
I just don't want to spend any brain power on strictly keeping in step. I prefer
to use that brain power to do the pathfinding I described earlier. This can
be done only by constantly moving the cane back and forth in the arc that clears
the way for both shoulders. I'm just paying attention to the information coming
from the tip of the cane in a different way from the way I was originally taught.
Third,
I don't center my cane. Rather, I rest the cane in a cupped hand down by my
hip in a hold that is comfortable and then impart the arcing motion to the cane
by a combination of wrist and finger motion. This is much more comfortable to
me than centering and tapping; my cane is long enough to correct for any disadvantage
from no longer being centered; and my fingers and wrist are free to gather information
as they move the cane, without being held near the middle of my body in what
is to me an uncomfortable wrist position.
For
this method of using a cane, I find that the very lightweight, hollow, fiberglass
straight cane works best. It's got a little give so that it flexes when it gets
stuck in a sidewalk crack or at the bottom of an obstruction, allowing me time
to stop or hesitate and to move my wrist upward so that I can free the cane
without the top of the cane hitting me in the solar plexus. The combination
of cupping the cane and its light weight and flex actually tell me things rather
than striking me.
One
final note on cane physics: change tips early and often. Gliding a tip does
cause wear, although I'm not sure any faster than tapping. The tip is a vital
part of the information-gathering system. I learned long ago that, when my tip
starts sticking, it's time to change it. At first changing the tip every time
my cane began sticking seemed wasteful. But every time it sticks and I check
it with my hand, the outer steel ring is nearly gone.
Good
tip glide is necessary to me for safe, efficient travel, so I change as soon
as the sticking begins. If I don't, my cane gets harder and harder to control,
and I begin to feel like a bad cane user, missing information and veering more
sharply. Changing the tip corrects all that like magic. I used to fuss privately
about the cost until I remembered that sighted contact wearers buy cleaning
solution. My tip-changing is merely my way of cleaning my contacts, so to speak.
I change tips as needed, which can sometimes be as little as seven days and
sometimes as much as three weeks.
Back
now to pathfinding with this longer cane, this free-form arc, and this comfortable
hold. I know some people are frustrated when the cane contacts all sorts of
things in the environment. I prefer this. Touching information as I pass it
helps to keep me oriented when I already know the path, and it helps me gain
orientation if I'm passing by for the first time. Trash cans, poles, retaining
walls, columns--all the stuff in my path inside or outside--give me information
I can use now or put on my map for later. Holding my cane in a cupped hand allows
me to move it out of the way quickly so that I can touch objects and not get
hung up on them or raise my wrist slightly to shorten the cane and stop to examine
the object. With my relaxed hold I can move the cane quickly to look, learn,
avoid, or whatever as I move safely and also continue to refine my map.
While
looking around, I am sometimes asked by a sighted person if he or she can help
me. I always answer that, no, I'm just sightseeing. Which is quite literally
true. The next time I pass that way, I will likely not pause but will touch
lightly the objects I now have on my map if I need them as landmarks. But one
quick examination makes my map more detailed and precise for later use.
This
is especially true in large open areas where I'm looking for information to
use later as landmarks. Easy landmarks are often there if you take a minute
to observe them in their correct place on the map. Sometimes no information
is available until you get to the other side of a large open area, in which
case it's important to know the details of how to find the door or hall you're
seeking when you get there, and context is important. A good mental map of a
large open area uses fixed sounds like escalators and fountains for direction
and details like potted plants; the turn of a wall; a change in flooring; or,
as outside Champions in Atlanta, a huge model of a baseball for more precise
identification of where you are and where you are going.
The
convention level in the Marriott Marquis is like that. Numerous large and small
meeting rooms are scattered around the perimeter of a huge central space, some
opening right off the atrium and some hidden down winding hallways. The most
efficient way to look for a door or a hallway in such large spaces is to cross
the open area in the general direction of the room you want and then begin to
look for details matching information on your mental map that guide you to the
specific door once you've arrived at the wall.
Over the years my own techniques
have changed as I've observed what works for me and listened to my blind friends
describe what works for them. For me the absolute bottom line is that blind
people can move successfully and safely through the world by using mapping,
reversing, and pathfinding. Some people, both blind and sighted, think this
just isn't possible. Many of my blind friends prove this contention false every
day. Many more blind people learning to use white canes hope it's true and are
working toward proficiency. All I can ask these people to do is to believe it
works, keep practicing, and hold tight to the notion that others are now confidently
using the techniques. If you start with the notion that "he or she is doing
it," then progress to the notion that "I can do it if I try,"
and just keep working, one day you will look over your shoulder and say with
a little surprise and a lot of pride: "Well, it's true! I do do it."
