They are(definitely) Happy, Interactive Installations, 2013

We are living together in one and only real world. But, the ways of recognizing real world are different from each other. For example, we can see many kinds of people like politicians or economists arguing about some problems caused by opposite interpretations for one incident everyday on news. In conclusion, we are living in an our own world interpreted by our own way. The artwork, 'They are (definitely) happy' is inspired by this sense of subject, that is, 'One real world and different my own world'. In this artwork, one participant is watching the video filled with hundreds of faces through unique glasses. All of them are smiling and look so happy. However, the other participant watching exactly same video without the glasses says that there are much more angry faces than happy faces. The participant wearing glasses tries to find the faces with different expression, but he fails. Finally, each participant draws completely opposite conclusion from what they saw, the one is "They are happy" and the other is "They are not happy". In other words, one real world is recognized totally differently. There is no correct answer or world. What I saw makes my own memory and constructs my own world.
Among the five senses of human, we trust the 'seeing' best. The saying 'Seeing is believing' is one of those clues. However, as the fovea which is responsible for accurate vision comprises less than 1% of retinal size but takes up over 50% of the visual cortex in the brain, human eye can recognize something accurately only in the region about five degrees from where they are focusing. This artwork is using this nature of human eyes. The participants are wearing a special glasses that can track their eye movement and this eye tracker finds where they focus. Among hundreds of faces in the video the participant are watching, several faces near the focused region are changed to 'happy' and the others become 'angry'. But the participants cannot aware the dominant 'angry' faces due to the feature of the fovea, and recognize only 'happy' faces.
