Gait Analysis & Emotional State Inference

Temporal Gait Dynamics and Discrete Emotion Recognition Algorithms

This research investigates how stride timing variations, cadence fluctuations, and locomotor rhythm patterns encode specific discrete emotions such as fear, anger, and joy. The investigation yields novel computational models that decode emotional states from biomechanical gait signatures with quantifiable accuracy metrics.

Kinematic Joint Angle Trajectories as Affective Valence Indicators

This study examines how changes in hip, knee, and ankle joint kinematics correlate with emotional valence dimensions ranging from positive to negative affective states. The research produces validated biomechanical markers that quantify emotional intensity through 3D skeletal movement analysis.

Vertical Ground Reaction Force Patterns and Emotional Arousal Mapping

This research analyzes how force platform measurements of ground reaction forces during walking reveal subcortical arousal responses and emotional activation levels. The findings establish force-based biomarkers for distinguishing high-arousal from low-arousal emotional states with mechanical precision.

Gait Asymmetry Laterality and Hemispheric Emotional Processing Lateralization

This investigation explores whether asymmetries in left-right limb coordination and weight distribution patterns reflect lateralized emotional processing in cortical and subcortical structures. The research advances understanding of how embodied emotional states manifest asymmetrically in motor control systems.

Machine Learning Feature Extraction from High-Dimensional Gait Kinematics

This research applies deep learning architectures and dimensionality reduction techniques to identify latent features within complex multivariate gait data that predict emotional state classification. The contribution establishes data-driven feature hierarchies that illuminate previously unknown emotional-motor relationships.

Neuromuscular Activation Patterns During Emotionally-Induced Gait Modulation

This study investigates electromyographic signals from lower limb musculature during emotionally-evoked walking to reveal how affective states alter motor unit recruitment strategies. The research uncovers the neurophysiological mechanisms linking emotional experience to muscular activation patterns.

Cross-Modal Integration of Gait and Facial Expression Emotional Congruence

This research examines whether gait kinematics and facial expression dynamics demonstrate congruent or dissociable emotional signatures across multimodal sensing systems. The investigation produces integrated affective inference frameworks that leverage both postural and facial channels for robust emotion prediction.

Longitudinal Gait Stability Metrics and Chronic Affect Dysregulation Phenotypes

This research tracks changes in gait variability, stride-to-stride fluctuations, and dynamic stability indices in populations with mood disorders or emotional regulation deficits. The study establishes gait-based biomarkers for longitudinal monitoring of affective state transitions and therapeutic intervention efficacy.

Entropy-Based Complexity Analysis of Emotional Gait Nonlinearities

This investigation applies nonlinear dynamical systems theory, sample entropy, and approximate entropy measures to quantify organizational complexity in emotionally-modulated gait patterns. The research reveals how emotional states alter the chaotic and self-organizing properties of human locomotion.

Contextual Emotional Inference from Gait in Naturalistic Ecological Settings

This research develops methods for detecting and classifying emotional states from gait data collected in real-world environments outside controlled laboratory conditions, accounting for contextual variables. The contribution advances ecological validity of affective gait assessment and develops context-aware emotion recognition systems.
