dc.description.abstract Relying only on visual presentation while performing multiple tasks can lead to distraction between primary and secondary tasks and delays perception of critical information. This research has proposed the use of auditory displays with the purpose of enhancing information perception by adding another channel to capture the user’s attention when needed. The audio-enhanced user interface was designed for the case study of a clamp-lift driver in a factory. Audio-encodings of nominal, ordinal, and quantitative data types were designed by following accepted design principles. The following types of the interface designs were evaluated: visual cues only, visual plus auditory cues, and auditory cues only. A number of questionnaires are created to collect information concerning suitability and matching of audio-encodings. Two evaluations were conducted to find benefits and drawbacks of auditory displays against visual presentation when performing single task and dual task. The results indicate that sound is more useful as an alert signal than as an informative representation. Users most preferred the visual plus auditory interface. Comparing between visual only and auditory only interface, visual only was preferred for single task while auditory only was preferred for dual task. en_US
