Path integration training. a) Virtual plane from the ego-perspective. b) Schematic drawing of the possible paths. Feedback was given after each trial (‘correct’ for pointing errors less than 10°, ‘near the mark’ for pointing errors less than 20° and ‘wrong’ for a deviation between correct response and given response of more than 20°).
