Wearable sensing hardware used as the basis of a custom multimodal collection system

Multimodal solution services

Synchronized sensing systems, delivered end to end.

Combine first-person vision with EEG, sEMG, IMU, pose, and continuous ground truth through custom hardware, firmware, calibration, SDK, and ODM delivery.

Custom systems

When a standard device cannot satisfy the data contract.

Zerolaw engineers the signal mix, timing precision, form factor, operating workflow, and software interface around the requirements of a research or product program.

Solution paths

One synchronized system across vision, biosignals, and ground truth.

Each configuration is adapted to the target model, collection environment, subject workflow, and output schema rather than assembled as an isolated sensor package.

Vision + EEG multimodal ODM

Hardware-synchronized first-person vision and high-density EEG.

A reference configuration for BCI research and embodied perception programs combines six-camera forehead vision with 1,024-channel EEG, unified triggering, and synchronized SDK inspection.

MULTIMODAL HUBUnified trigger, timestamp, and calibration

SDKLive inspection + synchronized replay

Ego + sEMG

Pair visible action with neuromuscular intent.

First-person RGB, grayscale, and IMU streams are synchronized with surface EMG so every action can be studied alongside the electrical signal that preceded it.

Inputs: Ego vision, IMU, sEMG
Alignment: Hardware timestamps below 50 microseconds
Outputs: Paired dataset, pose truth, synchronized SDK replay

Neuromotor & prosthetics

Train continuous control from 6DoF ground truth.

Combine first-person observation and sEMG with continuous hand-joint state to move beyond discrete gesture labels toward interpretable, frame-aligned control targets.

Ground truth: 21 keypoints x 6DoF and MANO-compatible hand state
Use cases: Prosthetics, rehabilitation, HCI, and dexterous control
Delivery: Synchronization, firmware, SDK, and calibration SOP

Solution delivery

From sensing requirements to a deployable collection system.

01Define signals
