What and when to say?

Unknown areas exist not only for the blind but also for their guides.
Although the obstacles are not physical, the guides need just as much
attention as the ones they help. As the activity requires co-operation,
it is essential that the partners would understand each other for
contacting is not possible through looks or gestures. Same goals usually
produce the same will. If the two prepare for races, they have to be on
equal terms regarding pace, timing and energy.
While running, some people who have a little vision or have a good sense
of location might run in a team or with a single guide without clinging
to a tetter. In this case, it is the best if the runners agree on ways
of communication which do not take energy yet carry the right message.
Instructions should be short and precise, lacking politeness as the goal
is not social interaction but the avoidance of accidents. Using
comparisons may ease the running process if the technique of getting
over the obstacle is compared to the object itself. If one knows the
qualities of the block, it is possible that the person will be more
confident and will know what to do because the association will make it
clear. For example, if there is a branch across the path, it is enough
to mention the railroad track, as they share some qualities with the
branch. First, they are across the path, stepping over them requires
the leg being raised in a way that is different from that of the one
used when stepping up on the bus or the other side of the road. Second,
they have their own heights which is important to notice in order to
prevent the leg from being caught. The positioning of the object is the
best if it is calculated based on both the position of the runner as
well as the obstacle. The most well known form of doing this is to use
the clock as an example. The center of the circle is the runner, the
places of the numbers on the clock are assigned to the positions of the
objects. the clockwise instruction is short, and informative. Stroller
