An auditory icon is a remantic iconic sinsign. Suppose that a program is closing and
real sound of closing window come out. Actually there is no relation closing program and
closing a window. But people may infer event of closing a program from only listening of
closing a window sounds. Sound of closing window has its own character. Although it does
not mean closing a program people accept it as a sign of closing program so that it is an iconic
sign, especially a metaphor. And it has only possibility of event of closing a program. It is not
closing a program in itself but something interpreted as closing of a program. And we can not
judge sound of closing a window true of false as using on event of closing program but
interpret it as a sign of some event happening actually so that auditory icon is a remantic iconic
sinsign.
Usability as Interpretation
Usability is a key concept in HCI (Preece, 1994). It is comprehensive concept including
safety, utility, effectiveness, and efficiency. It is concerned with making system easy to learn
and easy to use. It can be measured by accuracy, efficiency by time and satisfaction by
subjective workload. Even though a computer system may have a powerful capacity, users
avoid using the computer system which makes them annoying or confusing. For system
designers it is important to evaluate usability of their system design adequately.
Semiotics of auditory interfaces
Whatever auditory interfaces used in computer system are signs. The semiotic process
consists of the three stages. “In the first stage, ‘percept’ is produced by the action of
‘perceiving’ with the material sense data or external object. In the second stage, ‘sign’ is
