Haptic guidance by a force feedback device is a recent and original technology which provides additional proprioceptive cues during visuo- motor learning tasks. The effects of two types of haptic guidances-control in position (HGP) or in force (HGF)–on visuo- manual tracking (‘‘following’’) of trajectories are still under debate. Methodology/Principals Findings: Three training techniques of haptic guidance (HGP, HGF or control condition, NHG, without haptic guidance) were evaluated in two experiments. Movements produced by adults were asses
