Supposedly, it worked quite well - wearers got VERY good navigating with it and seemed to like the tech overall. Not sure why it disappeared - cost (it was probably made from pretty pricey tech for the time)? Weight ? battery life ?
Yes.
After 30 years of exclusively "joystick must be inverted Y" I got tired of being able to help other people play a tough spot of a game using their controller, and switched cold turkey. It took 2 - 3 weeks before I didn't randomly aim the wrong way, and 2 months to regain full accuracy.
Similar on the inverted scroll switch that Apple did when they married up scroll on iPad and Magic Trackpad. For several OS versions I stayed with the old way, then too many new users were a direction I couldn't handle, so switched. That switch took maybe 3 days to grok.
One of the weirder tricks you can do is hang upside from jungle gym or over the edge of a top bunk bed and "toss" a ball to your friend, which means you have to throw the ball "down" to them instead of toss it up. You can invert gravity much faster than you'd think!
