Introduction to Areas
and Sequences
There are two ways that messages can be
associated with keys. The first method is through
Areas. Area means only a single message is
recorded within a key Area. The key areas can
be of different sizes (large or small as seen on the
overlays) and the messages can be of different
lengths (from single sounds, words, phrases or full
speeches or songs). There is no relationship
between the length of a message and the size of
a key area. For example, you may program a
large area that says `Hello!' or a little one that
says `It's raining today; let's stay home.'
The number of messages possible on a level
depends on the keyboard layout chosen for that
level. For a 4x8 overlay, we are able to record 32
messages on one level when using Areas. You
can put one message in each key when using
Areas. For information and steps to programming
in Areas, you will read Chapter Three, Set Up and
Basic Programming of the DigiCom: Areas.
The second method of associating messages with
keys is called encoding or message sequencing.
Both Picture Sequencing and Spell Sequencing
use this method. Through sequences, a message is
accessed by pressing a combination of one or
more keys. Programming and communicating
using Picture and/or Spell Sequence is usually
more complex. For information about using
DigiCom in these methods, please refer to
Chapter Five, Picture and Spell Sequences.
( This chapter will also describe the sequence
prediction capabilities available to make these
methods easier to use.)
