Gait Recognition based on Underfoot Pressures
As an NSERC IRDF postdoctoral research fellow at ViTRAK Systems Inc., I evaluated a variety of existing and novel pattern recognition approaches to recognizing people by the way they walk, or their gait. Included in this was a phase of data collection, which involved acquiring the appropriate ethics approval. We found that it is indeed possible to identify people by their walking underfoot pressures, but that it is more challenging when a familiar user changes into different footwear.
