다중제품 상호작용의 인터페이스 디자인을 위한 사용성가이드라인

Background More products are using network and communication technologies. These products work together with other products as a system that provides expanded benefits to users. The product interface should be designed to reflect the features and requirements of the user's interaction with multiple device interface. This paper aims to propose usability guidelines for interface design of multiple device interaction on the basis of understanding the user's interaction. Methods From reviewing the related studies, I first studied usability problems previously recognized in the network and device association fields and solutions that attempted to provide intuitive user interaction. Second, through diagramming the interaction between a user and multiple devices in different cases, I found a feature of user interaction, which is different than single device interaction. Third, by interviewing technicians, I examined what users are required to perform when handling the connection of products. Fourth, based on the understanding of features and requirements of user interaction, I suggested usability guidelines for interface design of multiple device interaction. Results When a user interacts with multiple devices, the user deals with not only each device's interaction but also interaction between the devices. A user is required to handle complex interactions when establishing a connection between devices such as the devices' preparation, search of a device from another device, selecting a target device, approving and establishing the connection, and using the function of the system. The products' user interface should work as a system image for complex interactions. Conclusions The product interface should be designed to provide visible interaction status between devices, structured information and feedback to help users handling multiple device interaction, standardized interface and terms to help users' understanding, and proper help for recognizing, diagnosing, and recovering errors during interaction.
