function eyetrackerSmooth::eyetrackerSmooth ( )

This is the constructor for this class.

function eyetrackerSmooth::doSmoothing	(	in	me,
		in	in
	)

smooth data in M x N where M = 2 (x&y trace) or M = 4 is x&y for both eyes. Output is 2 x 1 x + y average position

static function eyetrackerSmooth::heuristicFilter	(	in	indata,
		in	level,
		in	steps
	)

static

Stampe 1993 heuristic filter as used by Eyelink.

Parameters

indata	- input data
level	- 1 = filter level 1, 2 = filter level 1+2
steps	- we step every # steps along the in data, changes the filter characteristics, 3 is the default (filter 2 is #+1) @out out - smoothed data

function get eyetrackerSmooth::smoothingTime ( in me )

calculate smoothing Time in ms

Property eyetrackerSmooth::smoothing

options for online smoothing of peeked data

Property eyetrackerSmooth::smoothingTime

calculates the smoothing in ms
