Bug: 5265529 Rewrote the velocity tracker to fit a polynomial curve to pointer movements using least squares linear regression. The velocity is simply the first derivative of this polynomial. Clients can also obtain an Estimator that describes the complete terms of the estimating polynomial including the coefficient of determination which provides a measure of the quality of the fit (confidence). Enhanced PointerLocation to display the movement curve predicted by the estimator in addition to the velocity vector. By default, the algorithm computes a 2nd degree (quadratic) polynomial based on a 100ms recent history horizon. Change-Id: Id377bef44117fce68fee2c41f90134ce3224d3a1 |
