“…Reusing data from this visual feedback group enables a direct comparison of the current motor learning study to results from our previous work [27]. Visual feedback is commonly used for control groups in motor learning studies [24], [39]. We hypothesized that training with the visual feedback allows the participants to learn spatial movement aspects at least as well as with the path control-based haptic control strategies, since the visual sense is highly specialized to perceive spatial information [40].…”

In literature, the effectiveness of haptics for motor learning is controversially discussed. Haptics is believed to be effective for motor learning in general; however, different types of haptic control enhance different movement aspects. Thus, in dependence on the movement aspects of interest, one type of haptic control may be effective whereas another one is not. Therefore, in the current work, it was investigated if and how different types of haptic controllers affect learning of spatial and temporal movement aspects. In particular, haptic controllers that enforce active participation of the participants were expected to improve spatial aspects. Only haptic controllers that provide feedback about the task's velocity profile were expected to improve temporal aspects. In a study on learning a complex trunk-arm rowing task, the effect of training with four different types of haptic control was investigated: position control, path control, adaptive path control, and reactive path control. A fifth group (control) trained with visual concurrent augmented feedback. As hypothesized, the position controller was most effective for learning of temporal movement aspects, while the path controller was most effective in teaching spatial movement aspects of the rowing task. Visual feedback was also effective for learning temporal and spatial movement aspects.

“…When the motions of interest involve multiple degrees of freedom, specific applications seem to need a unique tactile interface [2,4,5,8,9,11,12]. Actuators are strategically placed on specific joints or limbs that are identified as likely to need correction and users undergo a training session to learn how to correct their motions in response to the feedback.…”

“…Seven vibrotactile actuators were placed on their elbow, wrist, and torso to guide adjustments in posture, violin placement, and bowing hand movement. Other applications using similar methodologies include dance training [2], stroke rehabilitation [4,5], rowing [8,13], gait retraining [9], and snowboarding [11]. Advantages of this application-specific approach are that complex motions are broken down into components and that users are limited in the motion adjustments necessary; a disadvantage is that these tactile interfaces are not easily adaptable for other motor-learning applications.…”

“…Each developer uses different tactile algorithms, which range from providing graded vibrotactile stimuli [6], distinct levels of stimuli [14], saltatory patterns [7,10], or some combination thereof [1,8,9,11]. Recognizing this conundrum, Spelmezan et al and Jansen et al studied how users naturally react to vibrotactile stimuli applied on the body [3,11].…”

“…Jansen et al were able to demonstrate that users react faster to vibrotactile stimuli correlated to wrist rotation when users move toward a stimulus, and suggest that it is most intuitive to apply stimuli from an extrinsic (world) reference frame, as opposed to an intrinsic (body) reference frame. Of the above studies, [8,9,[11][12][13] have tested their systems on users with promising results, but only [9,12] have shown statistically significant results.…”

We present and evaluate an arm-motion guidance system that uses magnetic tracking sensors and low cost vibrotactile actuators. The system measures the movement of the user's arm and provides vibration feedback at the wrist and elbow when they stray from the desired motion. An initial study was conducted to investigate whether adding tactile feedback to visual feedback reduces motion errors when a user is learning a new arm trajectory. Although subjects preferred it, we found that the addition of tactile feedback did not affect motion tracking performance. We also found no strong preference or performance differences between attractive and repulsive tactile feedback. Some factors that may have influenced these results include the speed and the complexity of the tested motions, the type of tactile actuators and drive signals used, and inconsistencies in joint angle estimation due to Euler angle gimbal lock. We discuss insights from this analysis and provide suggestions for future systems and studies in tactile motion guidance.
