In-Depth Information
Walking with a walker is similar to the use of crutches in that it results
in a noncontinuous action and, like the use of crutches, is executed in
two separate and distinctive parts. Initially the walker is lifted or pushed
to a forward position. At this point some of the figure's weight is taken
by the upper body and arms, but more important, the frame affords
the figure a more stable platform and offers increased balance, which
enables the figure to walk to the forward position. The walk is then
interrupted as the walker device is once again lifted or pushed to the
forward position.
Discussing motions that are determined by factors other than an individual's
physical aspects or tangible external elements that have an impact on
movement leads us to the emotional and psychological factors that instigate
and drive our actions. This takes us into a realm of study of the human
condition, culture, society, and civilization. These are deep waters. Motivating
factors underpin the fourth and highest aspect of the Four A's of Animation:
acting. It is performance-based animation that makes up a major part of
animation production today in commercials, TV series, shorts, and features.
The study and analysis of action to create animated movements that may
be considered performance-based animation are the work of a lifetime. This
is a topic that deserves more in-depth study, but we can at least begin to
take a look at how these emotional factors may influence some of our rather
pedestrian and everyday actions.
A Happy Walk
It is evident that the way a figure walks will be determined by mood and
emotion. It should not really be necessary to state, though I will, that
obviously these states of being vary from individual to individual. Some
people keep their emotions hidden and their effect may be difficult to detect;
with other people it is only too apparent how they are feeling. How many
times have you been able to assess the mood of a friend or a family member
by their body language alone?
Let's consider for a moment the nature of a walk cycle that is influenced by
happiness. Receiving good news or, for that matter, anything else that puts a
person in a good mood and makes them happy may result in that individual
walking in a way slightly different from their normal manner. They might
move with more of a spring in their step; they might hold their body in a more
upright position; the stride may be slightly wider and the walk may be a little
quicker. There may be less evidence of a bend in the knee of the supporting
leg during the passing position. There may even be evidence in the angle of
head to the body; the chin may be held at a more upward angle and stick out
a little more. These signs may be very slight and could vary only marginally
from a standard walk, but they could be enough to identify the walk as a
“happy” one.
