Design and Implementation of a Usability Testing Tool for User-oriented Design of Command-and-Control Voice User Interfaces

명령 제어 음성 인터페이스 사용자 중심 설계를 위한 사용성 평가도구의 설계 및 구현

Recently, usability has become very important in voice user interface systems. In this paper, we have designed and implemented a wizard-of-oz (WOZ) usability testing tool for command-and-control voice user interfaces. We have proposed the VUIDML (Voice User Interface Design Markup Language) to design the usability test scenario of command-and-control voice interfaces in the early design stages. For highly satisfactory voice user interfaces, we have to select highly preferred voice commands and prompts. In VUIDML, we can specify possible prompt candidates. The WOZ usability testing tool can also be used to collect user-preferred voice commands and feedback from real users.
