“…A vibrotactile feedback system, combined with motion capture, has been developed also in the field of music in order to support the teaching of good posture and bowing technique to novice violin players with important results [11]. Several studies have shown the efficacy of vibrotactile feedback also during stroke rehabilitation [12] [13] [14] and gait retraining [15]. Vibrotactile displays can also support navigation and orientation while walking [16] [17] [18], driving [19] and operating in a helicopter cockpit [20].…”

Abstract-In this paper we investigate the influence of the location of vibrotactile stimulation in triggering the response made using two handheld joysticks. In particular, we compare performance with stimuli delivered either using tactors placed on the palm or on the back of the hand and with attractive (move toward the vibration) or repulsive prompts (move away from the vibration). The experimental set-up comprised two joysticks and two gloves, each equipped with four pager motors along the cardinal directions. In different blocks, fifty-three volunteers were asked to move the joysticks as fast as possible either towards or away with respect to the direction specified by a set of vibrating motors. Results indicate that participants performed better with attractive prompts (i.e. responses were faster and with fewer errors in conditions where participants were asked to move the joysticks in the direction of the felt vibration) and that the stimulation delivered on the back of the hand from the gloves gives better results than the stimulation on the palm delivered by the joysticks. Finally, we analyse the laterality, the relation between correct responses and reaction times, the direction patterns for wrong responses and we perform an analysis on the Stimulus-Response Compatibility and on the training effect.

“…This system used an array of servomotor-actuated paddles along the length of the arm to indicate contact in the virtual environment. One could also use tactile signals to help position players on a sports field or soldiers on a battlefield, utilizing the privacy of these signals in comparison to auditory or visual cues in order to gain a competitive advantage [1]. Rotational skin stretch represents an additional interesting method for tactile displays [2].…”

We present four wearable tactile actuators capable of recreating physical sensations commonly experienced in human interactions, including tapping on, dragging across, squeezing, and twisting an individual's wrist. In seeking to create tactile signals that feel natural and are easy to understand, we developed movement control interfaces to play back each of these forms of actual human physical contact. Through iterative design, prototyping, programming, and testing, each of these servo-motor-based mechanisms produces a signal that is gradable in magnitude, can be played in a variety of temporal patterns, is localizable to a small area of skin, and, for three of the four actuators, has an associated direction. Additionally, we have tried to design toward many of the characteristics that have made high frequency vibration the most common form of wearable tactile feedback, including low cost, light weight, comfort, and small size. Bolstered by largely positive comments from naive users during an informal testing session, we plan to continue improving these devices for future use in tactile motion guidance.

“…For instance, if the user has performed the movement accurately, she can receive a soft vibration as a reward; in turn, if she performs the movement in an incorrect way, the system can produce some force so that the user perceives resistance to that movement and thus, has to try in a different direction or way. Existing reviews show that vibrotactile devices are an appropriate means of providing immediate feedback for motor learning and augmentation [12]. By providing vibrotactile non-invasive stimulations to the surface of the skin, vibrotactile feedback does not hinder other tasks (e.g., speaking, seeing and hearing) and receives a high level of user's acceptance [15] without the need to shift the visual attention [13].…”

“…Anyway, haptic feedback is the one that makes the difference from non-motor skills training systems, as it can be specifically applied when physical movements are involved in the learning process [12]. This kind of feedback can be classified into [13] (1) tactile stimulations (i.e., electrotactile, thermal and mechanical); (2) kinesthesic (including exoskeleton forced-feedback systems); and (3) vibrotactile (i.e., vibrating components that deliver information through temporal parameters in the signal such as frequency, amplitude, waveform and duration).…”

Toward Personalized Vibrotactile Support When Learning Motor Skills

Personal tracking technologies allow sensing of the physical activity carried out by people. Data flows collected with these sensors are calling for big data techniques to support data collection, integration and analysis, aimed to provide personalized support when learning motor skills through varied multisensorial feedback. In particular, this paper focuses on vibrotactile feedback as it can take advantage of the haptic sense when supporting the physical interaction to be learnt. Despite each user having different needs, when providing this vibrotactile support, personalization issues are hardly taken into account, but the same response is delivered to each and every user of the system. The challenge here is how to design vibrotactile user interfaces for adaptive learning of motor skills. TORMES methodology is proposed to facilitate the elicitation of this personalized support. The resulting systems are expected to dynamically adapt to each individual user's needs by monitoring, comparing and, when appropriate, correcting in a personalized way how the user should move when practicing a predefined movement, for instance, when performing a sport technique or playing a musical instrument.
