“…The quantitative judgments of the perceptual attributes obtained in this study demonstrate a relationship between the physical parameters of seat vibration and attribute ratings. Interestingly, the attribute ratings seem to be comparable for different locations of introduction (hand vs. thighs), but the same vibration parameters [30].…”

“…Furthermore, it should be investigated whether the attributes of the suggested design language are also sufficient for describing vibrations introduced at other locations of excitation, e.g., hand-arm vibration or fingertip vibration. A comparison of seat vibration to hand-arm vibration suggests that identical vibrations elicit very similar sensory-perceptual attribute ratings at both locations of excitation [30].…”

In vibrotactile design, it can be beneficial to communicate with potential users about the desired properties of a product. However, such users' expectations would need to be translated into physical vibration parameters. In everyday life, humans are frequently exposed to seat vibration. Humans have learned to intuitively associate specific labels (e.g., "tingling") with specific vibrations. Thus, the aim of this article is to identify the most common sensory-perceptual attributes and their relationships to vibration parameters. First, we generalized everyday-life seat vibration into sinusoidal, amplitude-modulated sinusoidal, white Gaussian noise and impulse-like vibrations. Subsequently, the (peak) level, (center/carrier) frequency, bandwidth, modulation frequency and exponential decay rate parameters of these vibrations were systematically varied depending on the signal type. A free association task was conducted to reveal the most common sensory-perceptual attributes for each vibration. After aggregating similar attributes, the 21 most frequently occurring attributes were utilized in a second experiment to rate their suitability for describing each vibration stimulus. Principal component analysis guided the selection of six attribute groups, which can be represented by "up and down," "tingling," "weak," "repetitive," "uniform" and "fading." The observed relationships between vibration parameters and attribute ratings are suitable for future model building.

Smart wearable devices for human exposure vibration measurements on two-wheel vehicles

<p class="Abstract">The comfort experienced while driving a motorcycle is becoming a subject of great importance; indeed, the driver is exposed to vibrations that are typically caused by irregular profiles or wear of the road surface as well as by the aerodynamic influence and high-frequency rotation of the motorcycle engine. This paper discloses an original solution that allows the driver to monitor their exposure to vibration during a ride using a low-cost wearable device (smartwatch). A suitable measurement system has been designed and tested using a real motorcycle. The system captures acceleration signals in real time through Bluetooth communication and interfaces with a wearable device with a microcontroller unit that calculates vibrations transmitted through the driver’s hands. Different indexes proposed in the literature are adopted for the comfort analysis in both time and frequency domains. The hand transmitted vibrations are also experimentally compared with those measured through a fixed accelerometer according to the prescription included in the standard ISO 5349 to show the feasibility of the proposed approach in typical application conditions.</p>

Haptic virtual reality is often misunderstood as being solely a physically identical copy of real environments. Thus, a perfect recording and reproduction of vibration that is indistinguishable in an A:B comparison is often the aim. However, in most virtual reality applications the real environment is not available for direct comparison. Instead, when judging the plausibility of a presented scene, the user compares the vibration to his expectations shaped by the audiovisual context. Therefore, it should be sufficient to find any vibration that the user expects to potentially occur in the given context. Such a vibration needs to elicit a perceptual profile with a minimal distance to an expected profile in the sensory tactile perceptual space. Building onto this formalization, this paper demonstrates a novel generative model-based approach to authoring vibrations. First, users quantify expectations as tactile profiles consisting of ratings of six sensory tactile attributes without the presence of vibrations. Subsequently, the model predicts vibration parameters from such profiles. This ensures the fulfillment of user expectations and thus high plausibility. Furthermore, it eliminates the necessity of recordings, infeasible for scenes with no real counterpart and opens the door to crowdsourcing the authoring process with laypersons for the haptic metaverse.
