FIGURE 9.

The relationship between performance and differences in the position of the target comprising two classes when each movement was used as a different class. Performance was calculated based on the mean accuracy across all participants. If the number of features for the individual classification was 0, the classification accuracy was not included in the mean accuracy calculation. In both cases, classification accuracy tended to be higher for greater differences in position (p < 0.01; ANOVA for both cases).
