Introduction: Searching


'Searching' is a project by team '1+1', aiming to activate the interaction and collaboration between the students from different departments in the university(Korea National University of Arts), as it is not well carried out as student's expectation. In this project, the interactive installation searches a post-title which includes specific words("구함"/"구합"/"구합니다"-"search", "searching") in the website Everytime (, online university community) and accumulates them into a data file in real-time through python program in Rasberry Pi. When a person presses a button of the installation, a voice reads the title of a certain post through a speaker from the list of the data, and the time when the post is written is printed out in a piece of paper. (Team '1+1' members: Hwaeun Kim, Kyungjin Kim, Jungyoon Park, Yoonji Lee, Daeun Joo, <Team Learning 2019: Trouble Shooting @Seok-gwan Dong>, Art Collider, Korea National University of Arts)
