Recognition of Fingers movement Using Fiber Bragg Gratings in Silicon Elastomer Packing

Abstract

This work presents preliminary results from a single FBG sensor used to recognize fingers movement pattern. Six subjects had their movements acquired to signal processing through Linear Discriminant Analysis (LDA) further. Firstly, the index and middle fingers movements are discriminated within a training group of four subjects. To apply the LDA result, a test group of two subjects is used. Despite the non-symmetrical Gaussian samples distribution, the LDA technique was able to differentiate between the two fingers within all the subjects.
