It seems that we've come full circle. First, the ball was invented, and we used it to play catch. Then, the video game was invented, and we used it to pretend to play catch. Then, the motion-sensing video game was invented, and we used it to mimic playing catch. Now, a Mr. Louis Rosenberg is trying to patent a ball with which you can play catch.
It's not quite as ridiculous or opportunistic as it sounds. Rosenberg's idea is to fill an actual ball with electronics that can record direction, speed, and other variables. You actually play with the ball, and the ball's processor can score your throws. These scores can be displayed on a nearby console, such as a PSP, or shown through a head-mounted display. The game of catch has never seemed so high-tech.
