A Study on the User Experience to Improve Immersion as a Digital Human in Lifestyle Content

With the expansion of the digital environment and the metaverse, and the intervention of artificial intelligence, interaction in the virtual world is becoming more active. Humans are discussing the social reality of the user experience in this virtual space. Technology has created an object called a human-like digital human to enhance human immersion in the metaverse. This will become a factor that improves immersion so that the experience of the virtual world becomes more intimate for humans who feel unfamiliarity, alienation, and the rejection of new technologies. However, a clear definition, expression, and approach to the digital human are still being continuously improved. This article studied the direction of improvement in factors that can improve immersion in the user experience. In the process of communication between humans and digital humans, a qualitative survey was conducted based on the five human senses, where the user experience of the digital human was central. In-depth interviews were conducted with 20 men and women regarding their digital human experience, targeting Generation Z, who are familiar with the digital environment. Using NVIVO, global qualitative research software, 1000 main frequency words were derived, and the top 20 words with the highest frequency were classified into emotions and the five senses to analyze their correlation. As a result, we found that the mental models of developers and users are different in the digital human experience. Users felt more comfortable and a higher degree of intimacy when they saw the digital human as a technology, and the technology that the developer was showing was more focused on the external aspects that look similar to a human. It was found that, in order for users to immerse themselves in the digital human, various non-verbal expressions using the five senses should be further developed, rather than focusing on the human-like appearance. This study intends to serve as a cornerstone for research that can improve immersion in digital humans, with a high potential for future development.
