Learning new things is always gratifying, but sometimes bloody difficult. As an example, I’d like to take ballroom dancing. A little less than 2 years ago, my partner and I started with ballroom dancing. It’s gratifying, it’s fun and you can immediately see progress in new figures. Sometimes, at least, some figures are a lot more difficult than others (but that’s besides the point). Now that we’re a bit more advanced we’re also looking a lot more at posture and techniue. This is the part were I can get quite frustrated with myself. I should be able to hold my posture (look left, stretch that right side, baby!) but sometimes I just don’t notice that I’ve lost it because there are other points in the dance that need my attention.
In other words, I would like to get feedback on my posture through other means than the mirror or the dance teacher. Would there be a market for these kinds of gadgets?
