Therefore, this study's objective was to evaluate the effectiveness of various encoding methods for conveying information based on existing sensory substitution strategies, one being a line motion tracking task and the other a direction tracking task. The first encoding method was Perceived Position Encoding (PPE), where information was encoded into the perceived position of stimulation. The second was Perceived Intensity Encoding (PIE), encoded information into the perceived amplitude of the stimuli. Twenty-one participants performed tracking tasks using both the PIE and PPE methods. The results showed similar performance in line motion tracking between the PIE and PPE methods, although the extra motors used in the PPE method appear to introduce uncertainty in users. Nevertheless, users were significantly more accurate with direction tracking when using PPE. These findings highlight the need for task-specific encoding methods, and showcase the versatility of the HD haptic vest as a tool for augmented feedback in motor rehabilitation.</p>","PeriodicalId":13215,"journal":{"name":"IEEE Transactions on Haptics","volume":"PP ","pages":""},"PeriodicalIF":2.4,"publicationDate":"2025-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143965088","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We created 154 Tactons and conducted a study to collect acceleration data from smartphones and roughness, valence, and arousal user ratings (n=36). We converted the Tacton signals into two-channel spectrograms reflecting the spectral sensitivities of mechanoreceptors, then input them into VibNet, our dual-stream neural network. The first stream captures sequential features using recurrent networks, while the second captures temporal-spectral features using 2D convolutional networks. VibNet outperformed baseline models, with 82% of its predictions falling within the standard deviations of ground truth user ratings for two new Tacton sets.

The required force level is generally predetermined during design and closely relates to the human workload. This study investigated scenarios where discrepancies between human and machine control occur frequently owing to unreliable sensor information. We propose a method to allow the operator to adjust the machine's assist level, facilitating smoother control transitions and proving useful when machine suggestions are unreliable. Conventional HSC systems generally lack sufficient information for operators to make informed decisions regarding adjusting assist levels, leading to delayed decisions and increased workloads. To address this, our research objective is to communicate sensor reliability to humans, thereby facilitating deciding the machine's assist level.

There is a growing interest in understanding the neural mechanisms associated with haptic feedback using electroencephalography (EEG) measures. In particular, EEG hemispheric asymmetry is known to be correlated with various cognitive functions such as emotions, stress, anxiety, and attention. The current study aimed to investigate EEG hemispheric asymmetry associated with perceived urgency elicited using vibration feedback on the upper body. A total of 31 participants experienced three vibration patterns designed to elicit three levels of urgency, namely the no vibration pattern (NVP), urgent vibration pattern (UVP), and very urgent vibration pattern (VUVP). In the event-related potential (ERP) analysis, N100, P200, and P300 components were observed under the UVP and VUVP conditions. Notably, these components were absent under the NVP condition. The P200 and P300 ERP components as well as the participants' self-reporting confirmed the two distinguishable levels of perceived urgency (urgent and very urgent). Furthermore, the alpha and beta hemispheric asymmetry in the centroparietal area was significantly higher in the UVP and VUVP conditions as compared to the NVP condition between 500 ms and 2000 ms after the stimulation onset (One-way ANOVA test, Bonferroni correction, p $< $ 0.05).

VibTac seamlessly integrates vision-based and vibration-based tactile sensing modes to achieve high-resolution and high-bandwidth tactile sensing respectively, leveraging a streamlined human-inspired design for versatility in tasks. This paper outlines the key design elements of VibTac and its fabrication methods, highlighting the significance of the Elastomer Gel Pad (EGP) in its sensing mechanism. The sensor's multi-modal performance is validated through 3D reconstruction and spectral analysis to discern tactile stimuli effectively. In experimental trials, VibTac demonstrates its efficacy by achieving over 90% accuracy in insertion tasks involving objects emitting distinct sounds, such as ethernet connectors. Leveraging vision-based tactile sensing for object localization and employing a deep learning model for \"click\" sound classification, VibTac showcases its robustness in real-world scenarios.

In this study, we aimed to indirectly estimate the contribution of mechanoreceptors to the perception of illusory pulling torque cues by examining the relationship between vibration thresholds and the properties of these illusions, leveraging the known decline in cutaneous sensation sensitivity associated with aging (N = 40). Our results revealed an age-related increase in vibration thresholds, which is consistent with previous research. While male participants showed consistent sensitivity to illusory pulling cues across age groups, female participants exhibited a decline in sensitivity with age. Moreover, we observed only weak or no correlations between the vibration thresholds and the sensitivity of the illusory pulling cue. Although we were unable to identify any findings that explain the contribution of mechanoreceptors, we discovered a gender difference in the sensitivity to induced illusions among older individuals.

On the way towards fully AVs, we will experience an increase in numbers of automated vehicles on our roads, requiring the human driver to take back control in situations, which cannot be handled by the vehicle. These human-robot take-over requests (TORs) can lead to safety risks, in particular in scenarios when the driver fails to understand the TOR and, hence, lacks situational awareness (SA). In this paper, the correlation between reaction time, multimodal feedback, informing the human driver of a transition in automation level, and success of transfer of control has been investigated. Nineteen human drivers have participated in experiments in a full-sized driving simulator: First, the driver was engaged in a secondary reading task while the car was in self-driving mode. Then, a TOR indicated to the driver to take back control. Seven different feedback modalities for the TORs have been created consisting of an audio chime, a visual cue or a static mechano-tactile haptic feedback, or a combination of these. The mechano-tactile feedback is hereby given through soft pneumatic actuators embedded into a novel soft robotic driver's seat. After the driver experienced the TOR, they were given seven seconds to regain SA, retake the driving task and react to a road incident ahead. Based on the results, it can be concluded that reaction times below 2.6 seconds and above 6 seconds result in an unsuccessful transfer of control. Additionally, we have found that haptic feedback results in a timely and safe transfer of control within a shorter time frame, when added to currently commercially available auditory and visual feedback.</p>","PeriodicalId":13215,"journal":{"name":"IEEE Transactions on Haptics","volume":"PP ","pages":""},"PeriodicalIF":2.4,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143763922","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
