Explore the system

Five modes, one human data standard.

Full-body coverage, modular sensor capture, a traceable data pipeline, structured output and real interaction — translated directly from the Nexara system design.

01 / Full Body Coverage

One system covers the whole body

Front-and-back capture garments and external devices record motion, force, physiology and interaction together.

Head & torso
Gaze / expression / IMU / respiration
Hands & contact
Tactile array / six-axis force / position
Muscle & physiology
sEMG / heart rate / EDA / temperature
Lower body & sole
Gait / pressure distribution / force

Full coverage, high-precision synchronisation, wireless capture and live preview.

NexCap full-body capture coverage

02 / Sensor Matrix

Six modality families, combined on demand

The system is modular. Modalities are added or removed by task, body region and capture duration.

Vision & motion
Optical mocap / depth / gaze / skeleton / IMU / velocity
Force & contact
Six-axis force / pressure array / force plate / torque
Muscle & neural
sEMG / activation / muscle synergy / neural stimulation
Physiology & affect
ECG / HRV / respiration / EDA / SpO₂ / temperature / arousal
Voice & audition
Speech features / microphone array / source localisation
Cognition & behaviour
Gaze / attention / cognitive load / response time / social context

More than 200 synchronised channels across over 60 data modalities.

03 / Data Pipeline

Ready for training when capture ends

Time, space, task and version relationships are preserved from capture, reducing information loss in post-processing.

Unified time and space
Every modality calibrated to shared coordinates
Quality control
Automatic detection of anomalies, drops and drift
Traceable versions
Data, labels and training records remain linked

The Human Foundation Dataset supports both model training and evaluation ground truth.

04 / Structured Output

A complete human state on one timeline

Motion, contact, muscle, physiology, voice and cognitive data are accessible through one interface.

Engineering-ready
Unified format, units, coordinates and quality labels
Training-ready
Searchable by action, event and interaction segment
Evaluation-ready
The same capture establishes biofidelity ground truth

The data describes not only what happened, but how force and sensation moved through the body.

Motion & pose

3D joints / mesh / trajectory / velocity

Contact & mechanics

Pressure distribution / force vectors / torque

Muscle & neural

Activation levels / muscle synergy

Physiology & affect

HRV / respiration / EDA / arousal

Voice & audition

Speech features / sound-source localisation

Cognition & behaviour

Attention / load / response time

05 / Real Interaction

Captured inside real relationships

Scenes cover continuous interaction between people, objects, bodies and environments rather than isolated motion.

Everyday interaction
Natural movement and daily tasks
Contact collaboration
Passing / supporting / joint operation
Locomotion & gait
Walking / turning / balance change
Affect & social
Expression / prosody / social distance
Limit perturbation
Fatigue / sudden force / loss of balance

Real scenes teach the intent, boundaries and feedback behind movement.

Downstream

Human Foundation Dataset

Real human data is calibrated, repaired, annotated and versioned into the Human Foundation Dataset, which supports Human Foundation Model training and evaluation.

From capture to Human Foundation Model

NexCap full-body multimodal capture becomes the Human Foundation Dataset for model training and evaluation.
