Key Accomplishments:

Project: Active Heterogeneous Sensing for Fall Detection and Fall Risk Assessment, founded by National Science

Foundation (CNS-0931607), May. 2009 - Present

• Completed hands-on experience with acoustic microphone sensors and Data Acquisition (DAQ)

• Built and calibrated a circular acoustic microphone sensor array (8 microphones, radius 0.25 meter)

• Turned on sensors and recorded a long audio file consisting of a bunch of human fall and false alarm signals,

• Detected each sound event, and then recognized fall signals using carefully selected sound feature and classifier.

• Implemented a classic 3-dimension sound source localization algorithm (SRP-PHAT) to estimate the position where

• older people fell by giving an altitude angle, an azimuth angle, and the height with respect to the ground, and then

• kept tracking older people.
