Visually impaired individuals often face various obstacles when navigating blind roads, such as road disconnections, obstructions, and more complex emergencies, which can leave them in difficult situations. Traditional early warning methods suffer from low accuracy lack real-time capabilities. Therefore, this study proposes a novel system for traffic jams on roads. By analyzing the emotional state (normal, mild anxiety, extreme anxiety) electroencephalogram (EEG) signals of visually they are trapped, determine whether distress require assistance. Additionally, considering complexity environment fact that EEG prone to external interference during acquisition, introduces an improved deep residual shrinkage network based dense blocks (DB-DRSN). DB-DRSN replaces convolutional hidden layer original module with integrates connections optimize use both shallow features. The results show achieves 96.72% recognizing difficulties faced by impaired, significantly outperforming traditional models. Compared other methods, proposed offers quicker assistance individuals. demonstrated strong performance detecting about jams, greatly enhancing safety enabling timely detection intervention.

Highlights•Introduces ECG-EEG integration with eye-tracking for emotion recognition.•Employs pupil diameter metrics to refine emotional data accuracy.•Innovative Granger causality approach study brain-heart interaction.•Utilizes ResNet-18 high accuracy: 91 % and AUC of 0.97.•Outperforms state-of-the-art enhancement.AbstractThis introduces a groundbreaking method enhance the accuracy reliability recognition systems by combining electrocardiogram (ECG) electroencephalogram (EEG) data, using an gated strategy. Initially, we propose technique filter out irrelevant portions employing from data. Subsequently, introduce innovative estimating effective connectivity capture dynamic interaction between brain heart during states happiness sadness. (GC) is estimated utilized optimize input highly pre-trained convolutional neural network (CNN), specifically ResNet-18. To assess this methodology, employed EEG ECG publicly available MAHNOB-HCI database, 5-fold cross-validation approach. Our achieved impressive average area under curve (AUC) 91.00 0.97, respectively, GC-EEG-ECG images processed Comparative analysis studies clearly shows that augmenting refining strategy significantly enhances performance across various emotions.

Emotion recognition is crucial in human-computer interaction and psychological research, utilizing modalities such as facial expressions, voice intonations, EEG signals. This research investigates AI-driven techniques by employing Graph Neural Networks (GNNs) on functional connectivity matrices derived from data to advance emotion recognition. Our approach integrates sophisticated preprocessing methods, including Integrated Signal Enhancement (IESE) novel augmentation Gaussian Time Warping Generative Adversarial Network (GTW-EEG-GAN). integration aims at enhancing quality diversity. decomposition using EMD-Wavelet Hybrid Decomposition further refines feature extraction, enabling robust analysis of Functional metrics capture critical neural interactions intended for precise characterization. The GNN architecture effectively processes these features, achieving significant accuracy improvements. Evaluations the DEAP dataset demonstrate promising results, attaining 94.5% before hyperparameter tuning improving 98.6% after tuning, highlighting system's efficacy. methodology showcases advanced signal processing with AI, offering a comprehensive framework future studies. findings advocate potential applications areas personalized mental health monitoring, adaptive learning environments, responsive gaming experiences, demonstrating broad impact versatility EEG-based
