| Summary: | 碩士 === 國立雲林科技大學 === 工業設計系碩士班 === 91 === In order to improve the design of aural interface of human-computer interaction, this study, by using digital cameras as examples, has investigated the applicability of sound signals to the operational interface of electronic products and discussed the user’s cognition on sound signals and the selection of appropriate sound signals to convey demanded messages.
There were three experimental surveys conducted in this study. In the first survey, the use of the sound signals of digital cameras at present was explored. The second survey, which included an observation study of product operational behavior and an interview study, concluded that the applicability of sound signals was mainly affected by operational behavior, attention, image analogy, and discrimination. In the third experimental survey of quantification evaluation, 50 subjects were recruited to conduct the SD evaluation on the selected 30 sound samples and to evaluate the applicability of these sound samples to each of the selected 8 operational functions. The result of applicability evaluation showed that the sounds suitable for indicating operational functions could be classified into two kinds: abstract sounds and melodious sounds. The result of SD evaluation revealed that the users’ cognitive evaluation toward sound signals was affected by four factors: emotion, melody, tempo, and discrimination.
The result of the research concluded: 1. Among the 8 operational functions, the “on-off switch,” “confirmation of on focus, ” “low battery or off focus warning” were in common of the cognition of applicability. 2. There existed correspondence between operational functions and sound signals. For example, melodious sounds are applicable to “on-off switch” function; concise dual tonal sounds can be used with the “confirmation of on focus” function; downward gliding sounds are mainly suitable for “cancel” and “off focus” functions; whereas long single sounds, which can attract user’s attention, are supposed to be used for “low battery warning. ” 3. The suggestion of designing sound signals on operational interface summarized in this study can be directly applied to similar products, and provides the reference for developing related products and conducting related academic studies.
