Metadata analyses showing differential finger performance. Representative single finger trace data from a complex gesture (in this case 4 finger scale). (A) Finger performing as normally expected: fewer high velocity data points at impact with screen, relieving towards the end with many slower data points at the end. (B) stiff finger showing a significantly longer gesturing time, uniform low velocity throughout and uniform distribution of data points.
