Revealing the hidden lives of underground animals using magneto-inductive tracking
SenSys '10: Proceedings of the 8th ACM Conference on Embedded Networked Sensor SystemsPages 281–294https://doi.org/10.1145/1869983.1870011Currently, there is no existing method for automatically tracking the location of burrowing animals when they are underground, consequently zoologists only have a partial view of their subterranean behaviour and habits. Conventional RF based methods of ...

IN-Visible: perceiving invisible urban information through ambient media
CHI EA '04: CHI '04 Extended Abstracts on Human Factors in Computing SystemsPages 1348–1350https://doi.org/10.1145/985921.986061In this paper, we introduce IN-Visible, an urban system that enhances the contact between people and the subway. IN-Visible was conceived as a two-way system that brings users of the subway closer to the "exterior" urban environment and, through ambient ...
