If your algorithm is accurate, the ROC curve will be well above the 45 degree line. See http://en.wikipedia.org/wiki/Receiver_operating_characteristic. The ROC curve is a plot of true positive rate vs. false positive rate. The more accurate your code is in predicting the "true" gesture, the more your ROC curve will look like an upside down "L" shape (or capital Gamma shape).
