However, drivers remain responsible for driving safety. In the case of an automated vehicle failure, a driver must disengage from their NDRTs and take control of the vehicle. When fully engaged in NDRTs during Level 3 automation, NDRTs can compete for the resources for driving tasks, thereby depriving cognitive and physical readiness. This study investigated how compromised driver readiness affected takeover performance in situations with varying urgency levels. A simulated driving experiment was conducted with 32 participants in four states of readiness deprivation created through NDRT assignment, and two time budget levels were applied to represent multiple urgency scenarios. First, subjective ratings on readiness deprivation showed that depriving drivers of one form of readiness (i.e., cognitive or physical) adversely affected the other. Furthermore, retaining cognitive readiness may provide greater self-assessed utility. The NDRTs with similar interaction attributes generate comparable readiness deprivation ratings, offering a systematic way to evaluate their impact on takeover. Then, the impact of readiness deprivation on takeover performance varied significantly based on time budgets. With ample time, depriving drivers of physical or full readiness increased takeover time. However, these delayed actions, combined with stable lateral control, suggested a safe takeover strategy aimed at readiness recovery. Conversely, limited time hindered this recovery. Drivers performed takeovers despite impaired readiness, resulting in quicker but often abrupt post-takeover lateral movements. Notably, takeover actions were initiated once both cognitive and physical readiness were achieved, regardless of the time budget.","PeriodicalId":48916,"journal":{"name":"IEEE Transactions on Human-Machine Systems","volume":"56 1","pages":"171-181"},"PeriodicalIF":4.4,"publicationDate":"2026-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146045340","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}

Existing methodologies that employ transfer learning and knowledge distillation encounter challenges with limited generalizability due to substantial intersubject variability and constrained data availability. Furthermore, their applicability is often questioned, as most lack comprehensive external validation and cross-script evaluation. To address these limitations, we introduce P3-FSLNet, a few-shot metalearning framework that integrates prototypical networks and contrastive learning within a spatial-temporal convolutional neural network augmented by dual-channel attention for the selection of relevant electroencephalogram channels. Episodic metatraining facilitates the transfer of robust knowledge across different subjects. Evaluated on a self-recorded Devanagari script dataset, P3-FSLNet attains a classification accuracy of 93.17%, surpassing state-of-the-art methods by 1%–14%, while simultaneously reducing trainable parameters by up to 400 times. External validation using English-script datasets from BCI Competition II and III confirms its robustness in cross-subject and cross-script generalization. These findings demonstrate the efficacy of P3-FSLNet and represent a substantial advancement toward the development of script-agnostic P300 spellers that are lightweight, scalable, and conducive to multilingual applications.","PeriodicalId":48916,"journal":{"name":"IEEE Transactions on Human-Machine Systems","volume":"56 1","pages":"124-134"},"PeriodicalIF":4.4,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146045342","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}

To address this gap, this article proposes a comprehensive HCAI methodological framework (HCAI-MF) comprising five key components: HCAI requirement hierarchy, approach and method taxonomy, process, interdisciplinary collaboration approach, and multilevel design paradigms. A case study demonstrates HCAI-MF’s practical implications, while the article also analyzes implementation challenges. Actionable recommendations and a “three-layer” HCAI implementation strategy are provided to address these challenges and guide future evolution of HCAI-MF.

The widely used Text-to-Speech technology has issues such as privacy leaks in practical applications, and most of the new interaction designs proposed in recent years have limited application scenarios. Geared toward enriching interaction methods for users with visual impairments, this article explores the potential for translating Braille into vibrotactile cues as a way of conveying universal information. We designed a set of schemes and implemented them based on the vibration motor of a mobile phone. These schemes convert a single Braille character into several highly distinguishable vibration combinations, thereby conveying any information that Braille can express. Experiments were conducted on both sighted and visually impaired participants to evaluate the accuracy and efficiency. With a brief learning period of just 10 minutes, individuals can attain an accuracy rate greater than 95%, and the accuracy degradation remains minimal when playback speeds increase. By employing vibration motors to deliver comprehensive information, this framework shows promise for application in a wider range of technological devices.","PeriodicalId":48916,"journal":{"name":"IEEE Transactions on Human-Machine Systems","volume":"56 1","pages":"12-21"},"PeriodicalIF":4.4,"publicationDate":"2025-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146045334","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}

However, existing methods remain constrained by dependencies on specific reference videos or proprietary face mesh structures, limiting their applicability across diverse production pipelines and reducing compatibility with industry-standard animation workflows. To overcome these fundamental limitations in generalization and deployment flexibility, we propose Speech2Blend—an end-to-end hybrid convolutional-recurrent network that directly learns nonlinear speech-to-blendshape parameter mappings. This novel approach enables markerless speech-driven facial animation generation without restrictive inputs like video references or specialized facial rigs. Trained on the largest available digital human dataset (BEAT) and rigorously evaluated using three benchmark datasets with photorealistic visualization tools, Speech2Blend achieves state-of-the-art performance. It delivers superior audio-visual synchronization through learned temporal dynamics and reduces lip vertex error by 30% compared to existing baseline methods. These advances significantly lower production costs for virtual human speech animation while enabling cross-platform compatibility with common game engines and animation software.","PeriodicalId":48916,"journal":{"name":"IEEE Transactions on Human-Machine Systems","volume":"56 1","pages":"48-57"},"PeriodicalIF":4.4,"publicationDate":"2025-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146045351","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}

In such a context, physical human-robot contact becomes inevitable. Ensuring safety during human-robot interaction in home environments becomes a critical challenge. However, conventional methods mainly rely on creating a collision-free environment, which is insufficient for inevitable or even desirable human-robot contact. This article proposes a proactive safety architecture that smoothly switches between collision avoidance and contact reaction. To enable proactive sensing for homecare robots, a proximity sensor is customized with the abilities of approach and contact awareness. Based on the proximity sensing data, a proactive safety architecture is proposed to ensure continuous task execution while avoiding potential collisions. For inevitable contact, a pretouch and contact reaction strategy is designed to enable a seamless transition from proximity-sensing-based collision avoidance to contact reaction. Comparative experiments are conducted to validate the proactive safety architecture on a telerobotic system prototype. Compared with the three state-of-the-art approaches, the proposed strategy reduces contact force (by at least 35.21% along the primary collision direction) while maximizing motion-tracking performance. A user study is conducted to investigate the user experience. Feedback from 10 participants highlights positive evaluations of this system’s usability, indicating the feasibility of the proposed strategy in enhancing safety during human-robot interaction for the tele-homecare system.","PeriodicalId":48916,"journal":{"name":"IEEE Transactions on Human-Machine Systems","volume":"56 1","pages":"135-146"},"PeriodicalIF":4.4,"publicationDate":"2025-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146045344","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}

Due to the mechanical flexibility of exoskeletons, users can intentionally manipulate the resulting step length without alteration of the exoskeleton’s reference trajectory. This is generally achieved by manually applying wrench upon the exoskeleton and the ground using crutches. This work sought to investigate this mechanism as a deliberate means to control foot placement. Ten nondisabled participants were asked to pilot a user-balanced exoskeleton to target step lengths of 0.1 to 0.4 m, with the exoskeleton trajectory unchanged throughout the experiment. Performance was evaluated by mean absolute error (MAE) and standard deviation (SD) of resulting step lengths. To explore the degree that these results might apply to users with impairments, participants were asked to minimize leg muscle activations during the experiment. Simultaneously, surface electromyography (sEMG) data were collected and normalized between resting (0.0) and unassisted walking (1.0). Activations ranged between 0.014 and 2.853, and were used to categorize participants into High muscle activation (HMA) and Low muscle activation (LMA) groups. The LMA group (median MAE 0.026 m, SD 0.028 m) performed differently compared to the HMA group (median MAE 0.021 m, SD 0.021 m), however, most participants achieved acceptable performance across all target step lengths, compared to a 0.05 m guideline. The results confirm that step length can be controlled through exoskeleton users’ manual efforts. Whilst the range of adjustments may vary with device and user, this could facilitate simplified exoskeleton control strategies and an intuitive method of user control.","PeriodicalId":48916,"journal":{"name":"IEEE Transactions on Human-Machine Systems","volume":"56 1","pages":"2-11"},"PeriodicalIF":4.4,"publicationDate":"2025-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146045314","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}
