Real-time Motion-to-Haptic
Feedback System Built on nRF
Capturing hand movement and translating it into precise physical feedback using a dual-device architecture — motion sensor node to haptic actuator node, over BLE.
System Architecture
The setup consists of two independent units:
Core Challenges
Low-Latency BLE Communication
Maintaining fast, reliable communication between two independent devices over BLE — where any lag directly degrades the user experience.
Real-Time Motion Processing
Processing IMU data accurately at speed, filtering noise without introducing delay in the motion-to-output pipeline.
Drift-Free Movement Mapping
Translating orientation and movement into consistent haptic response — without accumulated sensor drift corrupting the feedback over time.
Stable Motor Control Circuitry
Designing motor driver circuitry that delivers precise, repeatable actuation — stable under varying load conditions and power states.
What We Built
IMU Motion Sensing Module
IMU-based motion sensing integrated directly with the nRF platform — capturing orientation and movement with the precision needed for real-time haptic mapping.
BLE Communication Pipeline
A low-latency BLE data pipeline connecting the control unit to the feedback unit — reliable, fast, and built to handle continuous motion data without packet loss.
Custom Motor Driver Circuitry
Purpose-built motor driver hardware for precise haptic actuation — stable under load, designed for the exact response characteristics the application required.
Real-Time Processing Engine
Firmware-level processing that keeps motion sensing and haptic output in tight synchronization — no buffering lag, no drift between input and physical response.
Tech Stack
Outcome
The system delivers responsive and synchronized behavior where physical feedback closely follows user motion, making it suitable for applications requiring precise interaction.
The end-use application is confidential, but the system reflects real-world implementation of motion tracking and haptic feedback.
