Abstract

Currently, people are paying more attention to smart home businesses. Therefore, the research on smart home system is becoming important. Smart Home App, which is an important component of smart home system, needs to consider the development of evaluation indicators for usability. In this regard, this paper takes smart home App as the object to develop the usability evaluation indicators of smart home App design. For this purpose, this study performed three rounds of survey by using the Delphi method. In the first round, 8 suitable areas were selected by collecting opinions from experts and analyzing the Content Validity Ratio, which was derived from literature review. Based on the results of the first survey, a total of 38 evaluation items were collected through prior research and user interview surveys. For the 38 collected evaluation items, 27 evaluation items have been selected by analyzing Average Value, Standard Deviation, Content Validity Ratio, Consultation and Convergence in the second and third rounds. The result of this study can be used as a guideline when evaluating the usability of smart home App design.
