If I continue to look at the real world through the screen, and then look at the real world without looking through the screen, I sometimes come back to myself and say, "Oh, so it's virtual. This work rediscovers the boundary between the real and virtual through the experience of touching an object in augmented reality, in which objects that should have been there disappear when touched. There is a trend in the world of imitating real-world expressions in augmented reality, and the boundary between the real and virtual is dissolving. On the other hand, I feel the ephemeral nature of augmented reality, which is expressed mainly through the visual and auditory senses, as experienced on smartphones, in which there is no substance, no matter how far you go. I used the motif of a dandelion's downy hair, which seems to fly away when you blow on it, to express this ephemeral nature.
