Accuracy and identification size. Translucent dots represent samples, with size specified by x-axis. Intervals represent 95% CI over the binomial success rate. Note the difference in scales between the top and bottom panels: 18DOF (top) uses positional and rotational data of head and hands and provides more features to train on than 3DOF (bottom) does.
