“…Haptic sensations can be presented at two locations. We determined that the dorsal side of the forearm is appropriate for the index finger, whereas the ventral side of the forearm is suitable for the thumb when touching a VR object [6]. Therefore, the upper and lower haptic presentation sites can be driven independently in conjunction with the movement of each finger.…”

“…However, the time and effort required to attach and detach most of these devices are significantly high, and the size of the device may interfere with the movement of each finger. To address these problems, we previously proposed a five-bar linkage mechanism that presents the information on the direction of the force applied to the fingertips and transmits it to the forearm [6]. This mechanism was driven by servo motors, and the direction of the force was successfully transmitted to the forearm.…”

“…First, we developed a system for accurate force presentation by extending our previous research. In our previous research, 1-0 control using RC servo motors was used, and there was no calculation and evaluation of the force being presented [6]. In this research, we constructed a device capable of transmitting the direction and magnitude of the force continuously by driving a five-bar linkage mechanism using a dc motor.…”

“…The Pump-and-Vibe has eight vibration motors mounted on the forearm arm and an air pump on the upper arm to modulate pressure (“squeeze”). Squeeze is thought to more effectively elicit emotional responses than vibration ( Tsetserukou, 2010 ) and has been deployed in a number of previous devices for various applications (e.g., Chinello et al, 2014 ; Gupta et al, 2017 ; Moriyama et al, 2018 ; Stephens-Fripp et al, 2018 ; Pezent et al, 2019 ). The Pump-and-Vibe system aimed to increase the emotional impact of music.…”

Cochlear implants (CIs) have been remarkably successful at restoring hearing in severely-to-profoundly hearing-impaired individuals. However, users often struggle to deconstruct complex auditory scenes with multiple simultaneous sounds, which can result in reduced music enjoyment and impaired speech understanding in background noise. Hearing aid users often have similar issues, though these are typically less acute. Several recent studies have shown that haptic stimulation can enhance CI listening by giving access to sound features that are poorly transmitted through the electrical CI signal. This “electro-haptic stimulation” improves melody recognition and pitch discrimination, as well as speech-in-noise performance and sound localization. The success of this approach suggests it could also enhance auditory perception in hearing-aid users and other hearing-impaired listeners. This review focuses on the use of haptic stimulation to enhance music perception in hearing-impaired listeners. Music is prevalent throughout everyday life, being critical to media such as film and video games, and often being central to events such as weddings and funerals. It represents the biggest challenge for signal processing, as it is typically an extremely complex acoustic signal, containing multiple simultaneous harmonic and inharmonic sounds. Signal-processing approaches developed for enhancing music perception could therefore have significant utility for other key issues faced by hearing-impaired listeners, such as understanding speech in noisy environments. This review first discusses the limits of music perception in hearing-impaired listeners and the limits of the tactile system. It then discusses the evidence around integration of audio and haptic stimulation in the brain. Next, the features, suitability, and success of current haptic devices for enhancing music perception are reviewed, as well as the signal-processing approaches that could be deployed in future haptic devices. Finally, the cutting-edge technologies that could be exploited for enhancing music perception with haptics are discussed. These include the latest micro motor and driver technology, low-power wireless technology, machine learning, big data, and cloud computing. New approaches for enhancing music perception in hearing-impaired listeners could substantially improve quality of life. Furthermore, effective haptic techniques for providing complex sound information could offer a non-invasive, affordable means for enhancing listening more broadly in hearing-impaired individuals.

“…LinkRing is designed to deliver multi-modal and multi-contact stimuli at the finger pads. The proposed device is based on the planar parallel mechanism, which was previously applied in several works [1,6,10]. Two parallel inverted five-bar mechanisms with 2-DoF each deliver tactile feedback in two independent points on the finger pads.…”

LinkRing is a novel wearable tactile display for providing multi-contact and multi-modal stimuli at the finger. The system of two five-bar linkage mechanisms is designed to operate with two independent contact points, which combined can provide such stimulation as shear force and twist stimuli, slippage, and pressure. The proposed display has a lightweight and easy to wear structure. Two experiments were carried out in order to determine the sensitivity of the finger surface, the first one aimed to determine the location of the contact points, and the other for discrimination the slippage with varying rates. The results of the experiments showed a high level of pattern recognition.
