Cicada Fingerprinting System: From Artificial to Sustainable

Published on

Location estimation with artificial infrastructures for mobile computing has been actively studied, but originally, people get a lot of information from nature during a course of a day. Nature including animals and plants supplies various information acoustically and visually. In this context, we present the concept of Cicada Fingerprinting System, which is a future localization scheme that will enable us to make the most of the information from nature. In our system, users collect the chirp of cicadas as acoustic data via smartphone embedded with microphone. Using the chirp of cicadas such as Wi-Fi fingerprinting, we can specify the location of users regardless of the existence of a roof. That is to say, cicada fingerprinting system applies cicada's instinctive behavior to a localization. Furthermore, by our system, users are able to feel a sense of belonging to a nature even in urban area, where we spend much time in daily life. This novel system is designed for making general users conscious of presence of nature around.

  • People get a lot of information That is to say, in traditional works, we have never utilized the natural information
  • So, through this work, I present
  • Essentially, most of us desired to have the contact with nature through kitchen garden, excursion, and potato digging. By these experience, children learn the value of nature and the greatness of the gift from the nature. But, nowadays, we spend a lot of time in urbanized area and developed area including underground subway for commuting. Therefore, we frequently arrange a journey to go to rural area for feeling a nature. Without having the relationship with nature, we would be getting stressful and mentally exhausted.
  • So, through my research, cicada fingerprinting system, we can make general user realize the value of the gift from nature again. And, the gift is location information which is universally recognized and useful information for our society.
  • The native habitat of cicadas depends on the species
  • Pigeons/crows
  • Here, I show the one of the results of our research. We have already collected acoustic data in mid-summer. And , in particular, we can find the broad distinction in several points. Frequency components are differed in each area which is depending on each cicadas inhabiting. And, additionally, now the full data analysis is under construction.
  • I don’t believe the chirp of cicada should be unique in all points. Even in other artificial fingerprinting systems, we combine the several schemes for accuracy.//
    For example, when you are in same room, which is geographically static, the sound you hearing is almost same song.
    Therefore, we tend to process these noise as environmental noise unconsciously. The native habitat is invaluable and unchangeable, and the closer you get to trees having cicadas, the louder the sound of cicadas is.//
    Yes, actually, we build the tool for participatory environmental sensing , and took the environmental noise level in the center of tokyo by participatory sensing, but actually, the noise level has changeable depending on the season, and I believe the existing participatory sensing is not practical because they have never assumed the presence of other creatures and the change of nature.
