In this first‑person demo recorded in New Zealand, Tom Gellie showcases Carv’s ski performance platform. He walks through the mobile app, demonstrating how video of a run can be synchronized with pressure sensors embedded in his ski boots and an iPhone in his pocket. The demo highlights multiple data streams – pressure distribution on each foot, G‑forces, speed, altitude, upper‑body pitch, ski angles, ski path, balance analysis, and edging metrics – and explains how each can be used by coaches or self‑reflective skiers to identify mistakes and improve technique. Tom also mentions an upcoming upgraded force‑plate sensor and hints at future testing in Canada.
Chapters
Hey there. So while I was in New Zealand working with the Rookie Academy this season, I got a chance to trial out the Carve technology. So I'm just going to give you a quick little look at one of the very, very cool modes, uh, function possibilities you can use this awesome technology for. So I've opened up the app, and on this particular day, Nico and myself, we went out, and I've got the pressure sensors in my boots reading all the info coming in from that stuff, and Nico synced his iPhone up using one of the features from this app. And what it does is it records video of me skiing and then synchronizes that with the pressure sensors under my boots. So you can pause or look at any particular part of my run, and I'm going to switch modes here to this really cool option and see exactly where the pressures are at a particular point in the turn. So for instance, here, right foot, my outside foot, the pressure is more towards the ball of the foot, and on my inside foot I'm starting to feel heel pressure. And so you can see as I go down the hill, those little pressure sensors move up and down. So really cool value of this is you could find, say, a mistake, a point where there's a mistake, and then figure out, you know, just before that point what happened, where your pressures were. And so this is great for coaches and people that learn through kind of self-reflection. I'll just go through a couple of the different things you can look up here. So, I mean, this technology is crazy. It picks up, you know, the change in altitude. So as you go down the hill, your speed, g-forces. So we'll have a look at the the turn that I created the most amount of G-forces, which is right here. And what's really cool is with this, uh, so G-forces max at this point, sort of just after the fall line, and then you can see it dips off right here, which to me is really nice because it means I dealt with the pressure and the transition really nicely. So let's have a look at the next one, upper body angles. The iPhone sits in your pocket and this Carv technology will pick up on the different angles that your body tips at. So pitch being how far forward your body is. So that particular point you can see right here, I almost get caught a little bit too far forward with my torso, and that's reflected with the pitch being more forward. So really interesting stuff it picks up on there. Ski angles. Again, we'll do the inside and outside boot in all 3 dimensions. We've got ski force, so here I would need Nico to help me out with analyzing this a little further, but pressure, X moment, Y moment. Let's see Ski, Ski Path. This would be interesting if you're looking at, say, even a race course. So you could perhaps look at line and see red where max pressures are, blue less pressure. And Live Replay Force and Motion. Unfortunately, my little things weren't totally synced up exactly, but here you can even see as I ski down that the, the pressure soles are moving in 3 dimensions as well as picking up on the forces. So that's a very cool mode on that one. Balance analysis will tell you difference, you know, between the right and left turn at the beginning and the middle and the end. And then edging, it'll just give you different colors for depending on where you're creating the most amount of edge angles. Overall, incredibly awesome technology. This is probably my favorite mode here to check out, to be able to see where your pressure is at particular points in the turn, if it's in the right spot or not, and checking left versus right, those sorts of things. Really awesome stuff. The guys at Carv are doing an incredible job. They're about to release a new updated sensor force plate, so look out for that one. And yeah, tune in more as I get to hopefully test this stuff in Canada. Thanks, see ya.
