DESIGN NAME: Tele Echo Tube
PRIMARY FUNCTION: Allows Users to Interact With a Forest
INSPIRATION: Tele Echo Tube is a speaking tube that acoustically interacts with a deep mountain echo through the slightly vibrating lampshade-like interface. In ancient times, interactions between nature and human societies were significantly less frequent due to cultural and mythological reasons. Japanese farmers prayed to gods in seasonal festivals for the weather conditions needed to ensure successful crop production and the general population was taught to respect the gods that resided in and protected the mountains. However, recent technological and information advancements, including satellite imaging, have been unable to confirm the presence of mythological creatures in undeveloped natural locations, and very few humans now believe in the existence of the creatures that control the weather or other farming conditions. However, because we no longer embrace the presence of such cultural and imaginable metaphors in our daily lives, especially in city life, there has been little outcry at the severe materialism brought about by the globalization process. Tele Echo Tube aims to increase the mythological awareness in the midst of a modern city beyond our cultural and imaginable boundaries. It is a speaking tube installation that acoustically interacts with a deep mountain ECHO through a networked remote-controlled speaker and microphone. It allows users to interact with the ECHO in a sanctuary forest in real time through an augmented echo-sounding experience. In doing so, this novel interactive system can create an imaginable presence of the mythological creature in undeveloped natural locations.
UNIQUE PROPERTIES / PROJECT DESCRIPTION: Tele Echo Tube is a speaking tube installation that acoustically interacts with a deep mountain echo through the lampshade-like interface. Tele Echo Tube allows users to interact with the mountain ECHO, Mr. Yamabiko in real time through an augmented echo sounding experience with the vibration over satellite data network. This novel interactive system can create an imaginable presence of the mythological creature in the undeveloped natural location beyond our cultural and imaginable boundaries.
OPERATION / FLOW / INTERACTION: To interact with the echo, users sing out YO-HOOOOO! very lively from the local speaking tube to the speakers in the mountain forest. A loop back call at the remote occurs while the playback sound from the speaker is re-captured and transferred to the user through the networked microphone with spontaneous network delay, experiencing a distant mountain forest soundscape in immersive and ambient ways.

PRODUCTION / REALIZATION TECHNOLOGY: Tele Echo Tube consists of remote and local speaking tube systems with one-way echo canceller through a full duplex audio I/O system over the network. The remote system, consisting of weather-resistant microphones and speakers, is placed in an uninhabited mountain forest in Japan (35,56,17.28,N, 138,48,11.04,E, Cyber Forest project site, located 1,200 m above sea level, 150 km from Tokyo). The remote and local systems perform an interaction to create an augmented echo-sounding its live sound pipe.
SPECIFICATIONS / TECHNICAL PROPERTIES: The technical operational testing notes of Tele Echo Tube can be found in our previous study.

RESEARCH ABSTRACT: Tele Echo Tube allows users to interact with the mountain echo in an uninhabited mountain forest in real time through an augmented echo sounding experience with the vibration over satellite data network. Tele Echo Tube is a speaking tube that acoustically interacts with a deep mountain echo through the slightly vibrating lampshade-like interface. This echo sounding loop, which transfers live sounds bidirectionally from the remote and local sites, creates echo sounding effect, and in doing so, gives the user the opportunity to feel the presence of a fickle echo even in the midst of a modern city.
CHALLENGE: The study was conducted in an uninhabited mountain forest at Chichibu University Forest, University of Tokyo in Japan. The availability of electric power and information infrastructures is either limited or nonexistent. The following system specifications were defined for the development.
1. The equipment must be able to operate in an extremely humid and hot subtropical forest environment.
2. The equipment must be highly stable to facilitate longterm unmanned operation.
3. The equipment must be remotely controllable to facilitate recovery from any unexpected system problems.
