Join Steven Lipton for an in-depth discussion in this video Signal and noise motion, part of Advanced iOS App Development: Core Motion.
- [Instructor] The second motion we want for our fencing app…is a parry, or block.…This is a side-to-side motion that blocks…the opponent's foil.…We'll model this as a positive or negative value of x.…As we did for thrust, we'll look at the data first.…Close the console and print the x-data, the console.…So before the y, we'll put x, colon, space, and again…percent seven point four, space,…and then add Excel x,…and we're ready to run,…so wake up your phone, and run.…
Start by running the phone width on your desk.…Pick up the phone and hold it in place for a second or two.…Move it back and forth from one shoulder to the other.…Go ahead and stop…and take a look at the data.…If you go back through the data, you'll see…values that greater than zero point one…and less than zero point one…are the side-to-side motions.…
When we looked at thrust, there was a very big number.…That made it obvious that we were thrusting.…In most applications, it's not that easy.…The noise, the data that doesn't mean anything to us,…might look a lot like the signal, the data that does.…
