We are now surrounded by multiple microphones available on various devices around us including wearables. This opens unique opportunities for acoustic sensing applications to enhance the spatial resolution of audio signals on the body. However, state-of-...

This paper presents the design and implementation of SPiDR, an ultra-low-power spatial sensing system for miniature mobile robots. This acoustic sensor produces a cross-sectional map of the field-of-view using only one speaker/microphone pair. While it ...

This poster presents the design and implementation of SPiDR, an ultra-low-power acoustic imaging system. This imaging system produces a cross-sectional map of the field-of-view using only one speaker/microphone pair. It leverages the fact that sound's ...

This paper presents a low-power and miniaturized design for acoustic direction-of-arrival (DoA) estimation and source localization, called Owlet. The required aperture, power consumption, and hardware complexity of the traditional array-based spatial ...

This demonstration presents a working prototype of Owlet, an alternative design for spatial sensing of acoustic signals. To overcome the fundamental limitations in form-factor, power consumption, and hardware requirements with array-based techniques, ...

In this demonstration we show how RFID technology can be used for sensing spatial information in indoor environments. In particular, we demonstrate how this sensed information can be used for navigation and interaction within an environment.
