Proportionality offset scaling: scale offset divisor
As described, besides the rest magnitude threshold, a proportionality offset was introduced. This offset is divided by the scale offset divisor Influence of scale offset divisor (with rest thresholding, Figure Higher averaged success rates were achievable for all scale offset divisors in kNN than for RR and RR-RFF. The best averaged performance when the pointing gesture was included could be achieved for With higher scale offset divisors, low-intensity level gestures Because of this, 5 was favoured over 10, although their performance appeared to be comparable (with 5 providing a slightly better performance when averaging over all dataset configurations, i.e. 93% vs. 91% with a comparable standard deviation).
