I am not the fastest learner, but I like to think that eventually I catch on how to do things. This is especially true for physical activities such as perfecting my basketball shot or golf swing. According to this article, researchers at Rice University will now be studying how students (as well as older learners) can use Wii, the video game, to facilitate learning. Essentially, by detecting early on where the glitch in your swing or stroke is, the device can show you correct way to do it and thus help you learn at an improved rate.
The technology may not substantially improve the world, but it should make a lot of kids—as well as some of us older duffers—better athletes.
