  • This study, as a case study of four university dormitories in Gwangju, examined the situation of interior space and conducted a quantitative survey investigating importance about the interior space and assessment factors of residential environment on users. Then user satisfaction at the assessment factors of residential environment was analyzed to draw problems and explore improvement. The results showed the following problems that should be resolved: Bedrooms should increase the area of convex space; toilets and bathrooms should be changed into a cluster type at least in common use by floor; rest space should reinforce heating and cooling system; robby space should become mixed space for various user's behavior; private fitness rooms should be planned as group fitness space; private libraries should reinforce lighting facilities; and computer rooms should complement and improve HVAC.

  • Smart home in the 4th industrial revolution environment is where all devices in the home are connected to each other to provide the optimal living environment desired by the user. Artificial intelligence speakers are being used as a way to manage and control all devices used in this environment. The function of an artificial intelligence speaker ranges from simple music playback to serving as an interface that controls and manages all devices in a smart home space. In this study, we investigated and analyzed the usability of artificial intelligence speakers based on the current status of domestic and overseas markets and the survey contents of two organizations (Korea Consumer Agency and Korea Information and Communication Policy Institute (KISDI)). In addition, we investigated and analyzed the usability of artificial intelligence speakers. Based on the results of responses from users from two related organizations, major problems were derived, and major improvement measures, such as discovering new functions and improving voice recognition performance, were also described.
