Since the sensor gets attached to the Velcro of the golf glove, does the sensor analysis the hand movement using an accelerometer? How the sensor analyzes ""Why did the ball go there?..."? How does it sense the trajectory of the ball and the distance the ball travels with that swing?
I wonder though, because the button attached to the golf glove, if that's the optimin location. I'm sure you get more info than not having it, but is there a better location? Or is attaching it to the glove the the best compromise between accuracy can practicality?
I've seen a lot of sports and fitness devices that use a smartphone as their UI and link to the Internet. This one also uses the phone's accelerometer as one of the sensors for the golfer's actions. The unit measures the hand movements while the smartphone measures the hip movements. I think it was a clever idea to make the phone part of the product's sensor array since it can be assumed to be already present as the display device.
Baseball has been into using data and statistics for several years now, but thiswill provide yet another set of metrics. But, it will be years, if ever, before players wear such devices in game situations. Baseball has only this year adopted video reviews of plays and we've had that capability for years.
In a way data acquisition might be better than video. Take a foul tip. Such a device would unquestionably tell if even the slightes foul tip occurred. Vidoes can still lave doubts if the foul tip is slight enough.
For baseball (a.k.a, American-rules cricket, sort of), knowing the trajectory of the ball eliminates any doubt of home runs. Crowd interference would be indicated by an abrupt change in the ball's trajectory. Strike zones would have to be defined by an umpire for each batter, which would allow the umpires some control of the game. They could even have a heads-up display to see the position of the ball as it passed over the plate and call balls and strikes appropriately and accurately, even consistently.
Drones are, in essence, flying autonomous vehicles. Pros and cons surrounding drones today might well foreshadow the debate over the development of self-driving cars. In the context of a strongly regulated aviation industry, "self-flying" drones pose a fresh challenge. How safe is it to fly drones in different environments? Should drones be required for visual line of sight – as are piloted airplanes? Join EE Times' Junko Yoshida as she moderates a panel of drone experts.
