Abstract

This study was conducted for the purpose of improving the usability of the product through the usability evaluation of the voice tag reader to improve the life convenience of the visually impaired. Perceived usability evaluation was conducted for 19 evaluation items based on the evaluation model considering the usability principle and the characteristics of the visually impaired. A total of 50 participants were included for the analysis. As a result of the perceived usability evaluation of the visually impaired, the safety of the voice tag reader, voice and sound quality, and accuracy of voice information were relatively satisfactory. It was found that the reader received a low evaluation in terms of efficiency in use, including the size and weight of the reader, and the convenience of carrying and storing. For the usability improvement, the procedure for using a product needs to be more simplified, and it would be helpful to input and supply tags for commonly used objects in advance.

이 연구는 시각장애인들의 생활 편의성 증진을 위해 음성태그리더기의 사용성 평가를 통한 제품의 사용성 개선을 위한 목적으로 수행되었다. 사용성의 원칙과 시각장애인의 특수성을 고려한 평가 모형에 근거하여 19개의 평가 항목에 대한 지각된 사용성 평가가 실시되었다. 제안된 시스템의 베타 버전과 정식 버전에 대한 조사에 1번 이상 참여한 총 50명의 시각장애인이 분석 대상에 포함되었다. 비모수 통계방법을 사용하여 분석한 결과, 음성태그리더기의 안전성과 음성 및 음질, 음성정보의 정확성에 대해서는 비교적 만족한 편이었으나. 리더기의 크기 및 무게, 휴대와 보관의 편의성을 포함한 사용상의 효율성 측면에서는 낮은 평가를 받은 것으로 나타났다. 사용성 향상을 위해 제품 사용을 위한 절차가 보다 간소화될 필요가 있으며, 일반적으로 자주 사용하는 사물에 대한 태그는 사전에 입력을 시켜서 보급하는 것이 도움이 될 것으로 판단된다.
