This British invention by an Oxford physics graduate with an economics PhD is getting rave reviews from skiers. Carv inserts electronics into each ski boot, connects by Bluetooth with your phone, and gives users a full-time virtual instructor on the slopes, measuring, quantifying and gamifying their skills.

Carv, inventor Jamie Grant tells me, involves two thin boot-shaped inserts, each containing 48 pressure-sensitive capacitors and loaded with accelerometers, gyroscopes and magnetometers. Your iPhone or Android also joins the party, tracking your body motion. All these sensors work in concert to sense outside ski pressure, turn symmetry, edge angle, balance and some 30 other metrics. You can customise your learning from beginner skills to quite fancy stuff and challenge yourself, your skiing companions or the whole world in acquiring certain skills.

It took Jamie and his team some 18 months to develop the first version in Shenzhen. This, version three, is the one that is making the breakthrough.
