This paper describes the design of user-interface widgets that include non-
speech sound. Previous research has shown that the addition of sound can im
prove the usability of human-computer inter faces. However, then is little
research to show where the best places are to add sound to improve usabilit
y. The approach described here is to integrate sound into widgets, the basi
c components of the human-computer interface. An overall structure for the
integration of sound is presented. There are many problems with current gra
phical widgets and many of these are difficult to correct by using more gra
phics. This paper presents many of the standard graphical widgets and descr
ibes how sound can be added. It describes in detail usability problems with
the widgets and then the non-speech sounds to overcome them. The non-speec
h sounds used are earcons. These sonically-enhanced widgets allow designers
who are not sound experts to create interfaces that effectively improve us
ability and have coherent and consistent sounds. (C) 1998 Elsevier Science
