Symforest is an interactive installation/experience manipulated by human emotion.

As a participant walk through the small dark forest in the room with a lantern, audio events (field recorded sound, narratives etc..) are activated depends on where he/she is. Galvanic Skin Response sensor, which detects emotional arousal of its holder by measuring sweat level on the skin surface, is embedded in the lantern handle; therefore, the lantern light changes its brightness depending on the emotional condition and controls audio volume. Therefore, each person has different impression of the space.
