Hey, how about we build a gesture‑driven haptic UI that lets us feel data trends in real time? Imagine tapping or sliding and actually feeling the velocity of a stock’s price or the oscillation of a sensor—hands feel the math, not just see it. What do you think?

Totally, low‑band signals work—let’s slap a low‑pass on the feed, map the filtered amplitude to vibration strength, and use a quick debounce so sudden spikes don’t feel like a punch. If the market drops faster than a hand can feel, we mute it. That way the user gets a steady pulse, not a jolt. Let's prototype the filter with a 5‑Hz cutoff, tweak the gain, and see if the hand keeps up. If it does, we’re good; if not, we’ll just say “nope” to that frequency.
