Mean performance measures accuracy, precision and reaching time, as well as the mean path length of the reaches in Experiment 1.

<p>Error bars indicate standard deviation over subjects and asterisks indicate significance (*: p<0.05, **: p<0.01, and ***: p<0.001). The assisting guidance condition improved the subjects’ performance with respect to all other guidance conditions: reaches were completed faster (both types of trials) and with increased accuracy and precision (blind trials).
