In this chapter we will deal with perception, i.e., the process of
transforming sensorial information to higher-level representations which
can be used in associative processes (memory access) and cognitive
processes such as reasoning. In the perceptual process, two basic
components can be identified as described earlier (figure 1.1 ,
right part). First there is the human sensory system with its typical
characteristics and constraints, providing the ``human input channel''
(HIC) processing functions. Second, there are those components of a
computer system which provide a multidimensional signal for the human user:
``computer output media'' (COM).
According to our basic model introduced in section 1 ,
we use the term perception to describe the communication from a
machine to a human. First, we will show the different kinds of human input
channels through which perception becomes possible and give a short
overview on these channels at the neurophysiological level ( 2.1 ).
The second part of this section ( 2.2 ) deals with devices and
methods used by computers to address these human senses. Finally,
in 2.3 we will present our results of bi- and multimodal
