Where to Start

By kuailesyj , 23 July 2013

Ok, I am incredibly newbie to this forum with a keen interest in coming up with ways of obtaining useful data.

So I am reading the white paper on motion processing.....I read about a sensor that can get the information from a bowling ball throw.

What I am looking for is to first find a sensor (fairly rugged) that could be put into the bottom of a finger hole and measure the rotation, tilt and forward motion of a bowling ball as it is thrown. Ultimately if the sensor had a battery and RF feature I would like to develop a coaching application where the bowler could use the information when combined with a video to get accurate feedback on what is and is not working.

All of this said if the sensor also measured the impact level on the pins that would be an added bonus.

I have yet to program applications but in the past I programmed in 4-5 languages that I became fairly good at. I have a master in Computer science with database specialty and I am just looking for better ways to improve my bowling as well as perhaps someday be involved in selling the sensors that individuals could buy to improve their own skills....perhaps a virtual coach once I gather enough data.....for example if your rotation is lower then your angle to the pocket may provide you with better results than simply adding speed to your ball.

Anyway if anyone can start leading me down the right path that would be fantastic. Ultimately I don't want to manufacturer anything as much as I want to have a dedicated source where the device could be purchased for a reasonable price then by purchasing the application you could start getting solid feed back.......who knows maybe it develops into much more.....or perhaps not but I know I would like to see what type of rotation and tilt I have without trying to go frame by frame on a HD video.....

I'm fairly new to this forum as well, but I must ask -- why does it need to be in the finger hole? Get an MPU-9150 with MotionFit and attach it to the back of your hand. You can get plenty of quality bowling data from a rig like that :)

Your idea is really cool! Once you accumulate enough data, you can start finding positive/negative patterns in your performance :)

We have some customers which utlize the sensor in a basketball, tennis racquet, or other sports equipment in a similar way. Sounds like a fun application. One thing to check, however, is the expected motion from the bowling ball. The sensor may saturate if it experiences accelerations above 16G, or rotations faster than 2k dps. If the bowling ball fits below this limit, one of the MPU 6 or 9 axis devices may be suitable for your testing.
