Today I present my idea, dynamic interactivity idea and concept, my idea is I am afraid of horror movie so my concept is using a small dark room and using the heartbeat sensor machine to test the audience after that the music slowly play, the music is using horror music to let the audience feel scared, when the audience heartbeat become faster the projector will show the horror picture on the wall. After critique I want to change my installation, i will make different type of installation with the same concept.
