“…Body vibrations with frequencies ranging from 10 to 20 [Hz] were shown to decrease arousal levels and induce sleepiness 2 . Moreover, drowsiness in vehicle drivers was shown to be induced in the frequency range of 4–10 [Hz] 34 , while motion sickness was reported below 0.5 [Hz] 6 , in particular, reported at 0.2–0.4 [Hz] 1 , sometimes enhancing arousal 3 , 7 , 35 . In the present study, simulation results obtained in condition 1 demonstrated that arousal level was high in a frequency range of 0.15–0.4 [Hz], while it was low in a range of 10–20 [Hz] (Fig.…”

“…Whole-body vibrations with a frequency range of 1–8 [Hz] cause health risks for drivers of forestry machines 52 , while those with frequency range of 2–8 [Hz] tend to decrease their operating performance 53 . Further, whole-body vibrations with a frequency range of 4–10 [Hz] were shown to induce drowsiness in vehicle drivers 34 . Based on our results from larger vibration stimuli, the BR and HR increased with greater vibration stimuli, but the LC entrained the respiration, which in turn entrained neuron groups within the brainstem.…”

Slow rocking chairs can easily put people to sleep, while violent shaking, such as during earthquakes, may lead to rapid awakening. However, the influence of external body vibrations on arousal remains unclear. Herein, a computational model of a locus coeruleus (LC)-norepinephrine (NE) system and cardio-respiratory system were used to show that respiratory entrainment of the LC modulates arousal levels, which is an adaptation to avoid physical risks from external vibration. External vibrations of sinusoidal waves with different frequencies ranging from 0.1 to 20 [Hz] were applied to the LC based on the results of previous studies. We found that respiratory entrainment of the LC decreased the breathing rate (BR) and heart rate (HR) to maintain the HR within its normal range. Furthermore, 1:1 phase locking enhanced arousal level while phase-amplitude coupling decreased it for larger vibration stimuli. These findings suggest that respiratory entrainment of the LC might automatically modulate cardio-respiratory system homeostasis and arousal levels for performance readiness (fight/flight or freeze) to avoid physical risks from larger external vibrations.

“…In future works, two Leap Motion sensors can be used to expand the interaction zone. Moreover, real social situations [59,60] will be examined in future work, introducing factors such as vibration [61] from driving and other means of transportation which would affect the position of the camera sensor. Therefore, this issue will be a challenging topic in future.…”

Most of the existing methods focus mainly on the extraction of shape-based, rotation-based, and motion-based features, usually neglecting the relationship between hands and body parts, which can provide significant information to address the problem of similar sign words based on the backhand approach. Therefore, this paper proposes four feature-based models. The spatial–temporal body parts and hand relationship patterns are the main feature. The second model consists of the spatial–temporal finger joint angle patterns. The third model consists of the spatial–temporal 3D hand motion trajectory patterns. The fourth model consists of the spatial–temporal double-hand relationship patterns. Then, a two-layer bidirectional long short-term memory method is used to deal with time-independent data as a classifier. The performance of the method was evaluated and compared with the existing works using 26 ASL letters, with an accuracy and F1-score of 97.34% and 97.36%, respectively. The method was further evaluated using 40 double-hand ASL words and achieved an accuracy and F1-score of 98.52% and 98.54%, respectively. The results demonstrated that the proposed method outperformed the existing works under consideration. However, in the analysis of 72 new ASL words, including single- and double-hand words from 10 participants, the accuracy and F1-score were approximately 96.99% and 97.00%, respectively.
