The auditory information is used for urgent notification or warning in vehicle because it is not restricted by the direction compared to the visual. However, since the hearing impaired drivers cannot recognize sound signal, various methods of visualizing the auditory information have been attempted to replace it. When visualizing auditory information, only important information should be selected and provided to prevent cognitive overload concentrated on the vision. For this purpose, analysis of the type of auditory information in vehicle should be given in advance. In this study, the types of auditory information in vehicle were analyzed based on the user experience of hearing impaired drivers. Through the observation of the driving behavior of hearing impaired drivers, 33 auditory informations experienced in vehicle were collected. The collected auditory informations were classified into 12 groups through open card sorting by an expert group, and the types of auditory information in vehicle consisting of four levels were presented through a relative comparison of importance between groups. The presented type of auditory information in vehicle can be used as a guideline for selecting important information when the auditory information is converted into visual or tactile. This study is meaningful in that the user experience analysis was conducted by observing actual driving in daily life of hearing impaired drivers.

청각 장애인 운전자를 위한 보조등을 개발하고자 한다. 청각 장애인들은 운전할 때 다른 차의 경적이나 구급차, 소방차와 같은 긴급 자동차의 사이렌 소리를 듣지 못한다. LED 기술과 아두이노를 활용하여 소리의 발생 위치와 종류를 시각적으로 표시하며, 진동으로 알림을 제공해 주고자 한다. 이를 통해 다른 운전자와의 오해를 줄이고 운전 중의 시각 집중도를 높일 수 있을 것이다. 이로써, 청각 장애인들이 운전 시 마주치는 애로사항을 완화할 수 있을 것이다. 이 제품은 다양한 차종에 적용할 수 있을 것이며, 청각 장애 운전자에게 자유로운 운전과 도로 안전을 제공할 것으로 기대된다.
