🎮 EMG Wrist-Controlled Paddle Game

Requirements:

• Device: Shimmer3R (EMG)
• Firmware: Version ≥ v1.0.22

⚡ EMG Electrode Placement

This game uses wrist extension and wrist flexion to control the paddle. To get good signals, place electrodes on the belly of each muscle. For the right hand, use EMG1 (Ch1N red and Ch1P brown). Polarity doesn't matter because the signal is rectified. Place the reference electrode (green) at an electrically neutral bony prominence (e.g., wrist).

✅ FLEXION — Locate Flexor Muscles

• 📍 Target: Flexor carpi radialis / ulnaris
• 🔘 Location: Inner forearm, 2–3 fingers below elbow

1. Sit with palm up
2. Bend wrist toward body
3. Place electrode on firm bulge

✅ EXTENSION — Locate Extensor Muscles

• 📍 Target: Extensor carpi radialis longus
• 🔘 Location: Outer top of forearm, near elbow

1. Rest forearm palm-down
2. Lift hand upward
3. Place electrode on tightening band

Tip: adjust the activation threshold slider to tune sensitivity.

Got it!
