The person on the screen is shown in actual size. In the absence of visitors, the person is probably looking straight or looking at a smartphone. However, when the visitor approaches 1.5 metres, the person shows a slightly nervous, excited, or unhelpful expression. However, when it comes closer to one meter, it shows more tension. If you approach less than 70 cm, the person in the video turns his or her eyes completely to the other side and shows unease. If it is less than 30 cm in length, the person on the screen cannot tolerate the discomfort and leaves the screen. Visitor can adjust the distance to see how pleasant the distance can be in relation to others.
