스마트홈 월패드 UI디자인에 대한 사용성 평가 연구

Abstract

As the information and communication technologies are embedded in Smart Home Wall-Pads, people can use smartphone at home or outside the home to control house temperature, lighting, security and gas, changing the paradigm of residential environment Wall-Pads manufactured by Hyundai Telecom, Kocom and Commax—which are Smart Home Wall-Pad manufacturer in Korea were selected for this study and examined through a heuristic evaluation. Based on the results, the direction of Smart Home Wall-Pad UI design development could be suggested. The results of UI evaluation of Hyundai Telecom Wall-Pad showed that users could carry out task without difficulty or discomfort, which implied high effectiveness and efficiency for users. On the contrary, Kocom and Commax Wall-Pad produced some errors when displaying icon for each function and consumed considerable time. Such errors in the function should be displayed with intuitive icon or words for menu in order to minimize error rate. The evaluation result showed low efficiency and memory simplicity for Commax Wall-Pad. Although the research was carried out after the task 1, the efficiency in the instruction was quite low and user’s experience hindered from remembering fully. It’s expected to see this study could help to conduct later research in UI design for Smart Home Wall-Pad systematically and professionally so that users could use advanced UI efficiently with no difficulty.
