Phd Thesis “Basic Research in Human-Computer-Biosphere Interaction”




This thesis presents the author’s vision of Human-Computer-Biosphere Interaction (HCBI) to facilitate a sustainable society. HCBI extends the subject of Human Computer Interaction (HCI) from countable people, objects, pets, and plants into an auditory biosphere that is uncountable, complex, and non-linguistic. Utilizing HCBI to experience forest soundscapes can help us feel one with nature, unaffected by physical distance. The goal of HCBI is to achieve ecological interaction between humanity and nature through computer systems without causing environmental destruction.

To accomplish this, information connectivity must be created despite the physical separation between mankind and the environment. This combination also ensures ecological neutrality. This paper presents the concept overview, related work, method and developed interfaces. Using prerecorded animal calls, bio-acoustical feedback from the target wildlife was produced. This thesis focuses primarily on reviews of the design and evaluation of a bio-acoustic interaction system utilizing tracking collars, microphones, speakers, infrared cameras, infrared heat sensors, micro-climate sensors, radio-tracking devices, GPS devices, radio clocks, embedded Linux boards, high capacity batteries and high speed wireless communication devices.

Furthermore, this paper demonstrates that bio-acoustic based food chain information in a biosphere is a potential nonverbal information interface among human beings, computers, and the biosphere and can facilitate interaction with life in ecosystems such as wild animals. Furthermore, the study investigates the potential application of a wildlife presence detection method based on their animal call detection and remotely controllable capacitance sensors for wildlife telemonitoring in ecological studies, which could integrate computer systems into the global ecosystem.
