From your hands to the game

Hardware → signal → adaptation · reasoning across the stack

Most UX portfolios stop at the screen. BlitzMind’s interface starts in silicon — sensors feed on-device ML, which produces the metrics the UI is built around. Designing across that whole chain is the differentiator.

01 · Sense
PPG · AFE4900

Optical pulse sensor in the grip

→ Heart rate · HRV
Grip · FSR

Force-sensitive resistor per handle

→ Grip pressure · tension
Motion · BNO055

9-axis inertial measurement unit

→ Micro-tremor · motion
02 · Compute · ESP32

On-device ML fuses the three streams into player-state metrics — no cloud, low latency.

The game responds silently — no pop-ups, no pauses.

The same signals power the session report — correlating Calm Score and HRV against win rate, reaction time, and recovery, so the loop improves every session.
