be easily detected by means of distant acoustic sensing. This result was also confirmed by means of direct measurements of velocity field of the vortex flow.

We consider the rate-distortion problem for recording a Gaussian acoustic field with an array of sensors equipped with microphones. Our analysis is based on the field’s spatiotemporal correlation structure, which is induced by the physics of sound propagation. Under certain assumptions about

Abstract—The issue of how to efficiently represent the data collected by a network of microphones recording spatio-temporal acoustic wave fields is addressed. Each sensor node in the network samples the sound field, quantizes the samples and transmits the encoded samples to some central unit, which

-pand the expressiveness of touch interfaces by augmenting touch with acoustic sensing. In our vision, users can natu-rally express different actions by touching the surface with different body parts, such as fingers, knuckles, fingernails, punches, and so forth- not always distinguishable by touch technologies

This dissertation evaluates the claim that “acoustic sensing on mobile computers can provide accurate user presence and location information while requiring no new hardware. ” We introduce two new acoustic sensing techniques for computers; one is a sonar system for detecting user presence

We describe Lamello, an approach for creating tangible in-put components that recognize user interaction via passive acoustic sensing. Lamello employs comb-like structures with varying-length tines at interaction points (e.g., along slider paths). Moving a component generates tine strikes; a real

We present the design, implementation, and evaluation of the Acoustic Embedded Networked Sensing Box (ENSBox), a platform for prototyping rapid-deployable distributed acoustic sensing systems, particularly distributed source localization. Each ENSBox integrates an ARM processor running Linux

In this paper, the problem of underwater scene understanding from multisensory data is addressed. Acoustic and optical devices onboard an underwater vehicle are used to sense the environment in order to produce an output which is readily understandable even by an inexperienced operator. The main

ii ACKNOWLEDGEMENTS Piranha has a very distinctive smell. I’m guessing that whenever I am unlucky enough to smell this obnoxious odor in the future, I will be reminded of life under yellow light in a bunny suit. However, I don’t think my mind will dwell for long on memories of late nights in the cleanroom or lengthy finite element computations. Instead, I’m sure my thoughts will quickly turn to the faces and voices of the people who populated the cleanroom, the graduate student offices, and the laboratories in Ann Arbor. Because people, of course, are what make an experience worth remembering. First, let me thank my family; the foundation on which everything else has been built. The most important year of any PhD is the middle year because that’s the year you get married. So, Jane, thanks so much for your love, support, and friendship. I also want to thank my parents and sister for all their support and love, and my parents-in-law and sister-in-law for their support and love. I am very grateful to Prof. Grosh for his direction, advice, and guidance over the course of the degree. He has always made time to help me with any difficulties I encountered, and has made it as smooth as possible to progress through the various stages of the degree. I appreciate his creativity, clear thinking, and good humor. I am also thankful for the help
