We believe that "earables" is the next significant milestone in wearable computing. With sensing, signal processing, and communications converging into these devices, we envision a host of new possibilities within the next 5 years. The leap from today’s ear-phones to "earables" would mimmic the transformation from basic-phones to smart phones. Today’s smartphones are hardly a calling device anymore, much like how tomorrow’s earables will hardly be a wireless speaker or microphone (see our vision slides here).
Earable Computing: A New Area to Think About
ACM HotMobile, Feb 2021.
This position paper argues that earphones hold the potential for major disruptions in mobile, wearable computing.
Angle-of-arrival (AOA) Factorization in Multipath Channels
IEEE ICASSP, June 2021.
This paper considers the problem of estimating K angle of arrivals (AoA) using an array of M > K microphones, for unknown and correlated source signals.
Ear-AR: Indoor Acoustic Augmented Reality on Earphones
ACM MobiCom'20, September 2020.
Ear-AR enables indoor acoustic augmented reality on smart earphones, by using a fusion of ear IMU, phone IMU, and acoustics to do better indoor localization.
STEAR: Robust Step Counting from Earables
ACM Earcomp (Workshop with Ubicomp'19), September 2019.
STEAR identifies smart earphone IMU as a much better sensor compared with phone or watch IMU to do step counting due to the much cleaner IMU signals on the ears.
We are looking for PhD students with background in sensing, (acoustic) signal processing, communications, embedded systems, and machine learning.
