The digital human experienced through virtual space and lifestyle content was not perceived as a human being and was mainly expressed as a technology. Therefore, in terms of emotions, words such as awkwardness, fear, alienation, rejection, and discomfort were predominant. In addition, looking at the word frequency ranking, it can be seen that the emotional content of the extracted words was overwhelmingly large Figure 5.  
It was observed that humans were unfamiliar with digital humans through the number of negative words related to 'emotion'. Furthermore, as a means of showing this emotion, it was found that appearance, behavior, face, voice, and movement had a great influence via words related to the 'five senses'. As a result, there were many elements related to non-verbal communication, and the senses that presented the greatest influence were sight and sound, Figure 6.  
Figure 5: Word Frequency Ranking for ‘Emotion’. The cluster map in Figure 7 shows the importance of the size of the circles, and the distance between the circles shows their correlation and depth. Moreover, the color of the circle was grouped according to the relationship of the words. Therefore, it is composed of words that are seen in the realm of a digital human and a human, and words that relate to the interface between the two. Looking at the area of contact, it shows that the sense of heterogeneity between the two areas can be reduced and the gap can be reduced depending on the space, expressive power, atmosphere, technology, and means of communication for empathy between the two areas. When looking at the results of each data analysis and the context of the interview, the point that humans sympathize with in relation to digital humans was 'unfamiliarity'. In addition, it was possible to see the difference between the viewpoints of the digital human expressed by the developer and the digital human experienced by the user in the elements inherent in the phrase'sense of difference'. Currently, artificial intelligence companies that

However, it was this 'humanity' that people felt most uncomfortable with when they encountered the digital human. * Interviewee A: When a digital human takes actions to make friends with humans, it seems that is good or that the marketer writes well. In the end, because you don't feel like a digital human, you're reminded of the real person behind them. * Interviewee B: When I watch Disney's or Pixar's animations, I never thought that I felt alienated because I was different from humans. Some even think that they are'real people', but when I see a digital human, I get a lot of the feeling that it's fake.
