one of the hardest parts of racket sports is learning proper
swing mechanics, for instance golf, tennis, table tennis.
You can hire a coach and spend years and lots of money
perfecting a swing.
the hard part is some shots have limited feedback, i.e it's
hard to FEEL if you're doing it right
due to limited
resistance, instead you rely on feedback from a coach
adjust your swing, then hopefully lock it in and practice
practice practice until it's good.
I suggest a two part technology.
First pro's would wear a high resolution motion capture
suit, plus accelerometers on their racket, wrist etc to give
detailed information about how their perfect strokes move
next the amateur would wear the same rig, plus some
cleverly placed gyroscopes and vibrating motors. During
the stroke the computer would compare your wrist angle,
racket position etc to the pro player. If it saw that you
were twisting your wrist too early or late or what not. It
would apply resistance on that axis in the form of
gyroscopes and vibration.
That way you could FEEL if your stroke is right or wrong.
This could be applied to other activities like driving
vehicles etc. anywhere you can study a "good movement"
then compare the students sloppy movement and try to
nudge them back into a better position.
alternatively you could use one of thoses powered
exoskeletons but have it apply resistance instead of
State of the art haptic feedback

||Oh it's a racket alright...
||...and don't call me 'sport'.
||sounds like a Wii that fights you.
||Definite (+). I'm not sure if the Wii can be
programmed to give enough feedback -- you'd need a
mechanically tracked system adjusted to a larger
scale (see link)
||I think people are fishboning it because golf isn't a
racket sport... it's a "club" sport, the point is they
both have very complex strokes, with limited
feedback during the stroke. This technology would
help you to feel a proper stroke better and get it
into muscle memory easier
||You get tennis clubs as well you know.
||has anyone tried using a racket for golf? I wonder how a tensioned string head would do?
||Technically, aren't these all 'stick-and-ball' sports?
