In this paper we presented an audio sensor array designed for person tracking and fall detection.
Key design features of the array such as the number of microphones, the preamp setting and radius, were determined using a Matlab array simulation toolbox.
Due to the lack of space, we only presented the array radius choosing procedure, the other choices being done in a similar fashion.
While we showed that person tracking is a possibility, we have not implemented a complete audio tracking algorithm.
Preliminary fall recognition results are encouraging, although more realistic experiments such as fall in presence of noise (such as TV) are necessary.
