Lissajous figure

(ˈliːsəˌʒuː; ˌliːsəˈʒuː)
n
(General Physics) a curve traced out by a point that undergoes two simple harmonic motions in mutually perpendicular directions. The shape of these curves is characteristic of the relative phases and frequencies of the motion; they are used to determine the frequencies and phases of alternating voltages
[C19: named after Jules A. Lissajous (1822–80), French physicist]

Terminal feedback was provided to the participants via a computer monitor (AMA VGA colour monitor, model SC-431VS), situated 45 [degrees] to the left of the participant, that displayed a Lissajous figure (a real-time summary of the displacement-displacement plots of the right limb against the left limb, see [ILLUSTRATION FOR FIGURE 1 OMITTED]).
Lissajous Figures, displaying V/I curves, or the phase difference between two waveforms is possible in XY Mode.
Both voltage and current signals were plotted as lissajous figures on the screen of oscilloscope.
