Rest class thresholding: rest magnitude threshold
The rest magnitude threshold was introduced to cope with the problem of separating intermediate gestures from the rest class in the proposed proportional control. In order to evaluate the influence on the user success rate, multiple tests were conducted with the gesture sets (rs, pw, fl, ex) and (rs, pw, pn, fl, ex).Figure Influence of rest magnitude thresholding, pilot experimentsInfluence of selected gestures, introducing rest magnitude threshold (Since there was no difference recognizable between the success rates of It has to be noted that the results of RR-RFF yielded larger standard deviations than in all kNN cases. This could signify that kNN performs more stable and robust with less nondeterminism in the algorithm’s behaviour.
