A design guide-line of auditory display for electric appliance
MetadataShow full item record
The auditory channel is important for communication between computers and users because of its properties, such eye-free communication and strong attention grabbing properties. However, interpreting the meanings of sounds is not a trivial task. Users have to learn and memorize the mapping between sounds and their meanings for each device. Therefore, as the number of devices increases, this becomes challenging for users. To mitigate the challenge, it is desirable to use sounds that users can understand intuitively. Thus, investigating the intuitiveness of sounds is of significant interest. In this work, we investigated 2,012 sounds consisting of 48 earcons, 80 auditory icons, and 1,884 beep sequences through a series of user studies using Amazon Mechanical Turk as well as a lab study that validated the results of the Mechanical Turk studies. The results provided a guideline for designing sounds that users might understand more intuitively.
