using 9dof data to overlay on a distant object

hey folks just wanted to say thanks for all the info I have been reading up on a few things but wanted to get a few more narrowed answers. I first must say I am new to all of this and know just about enought to know im over my head and thought I would ask some of the experts. So please use small words haha

the end game is:

I would like to plot data for 30 seconds max of the natural movement and float of an object that a person is holding. the movements would then be overlaid on to an img that the person is looking at. the img does not have to be the exact same one but could use a stock picture. the img would be at a short distance say 10ft

I think I will be able to use a 9dof sensor to track the float of the object at the persons hand. Since I do not have the skill to make my own I thought of buying one premade like the node+ and I should be able to plot that with matlab (fingers crossed)

my main problem is how can I keep this “float” relative to the img the person is looking at?

any ideas or thoughts on the whole project?

I’ve read the above 3 times and I still don’t get it. What do you mean by “float” ? Do you mean height ?

I think he is trying to plot an object in 3D space. And have a program plot the course that object is taking. But his statement doesn’t really clarify what he wants. From what I can gather, he wants to plot the course and save it somewhere, then transfer it. That is how interpreted his second paragraph.

Now, if you want to do the above in real time, then an Arduino can’t do video processing.

sorry guys for the confusion

yes I am trying to plot the movement of a object in a 3d space record it and use it to study the movements and make adjustments

let me try it a different way

say that you are 30ft from a wall and on that wall was a 2" painted circle

you then reach out with your hand and hold a laser pointer and shine on the target

the laser will not stay in the same spot it will move around the target

also on that hand there is a sensor that captures those small movements and plots them on a 3d graph

that graph we just made needs to be relative to the 2" circle we are pointing the laser at

where on the wall does the laser first point which is normally outside of the 2" and then trace that line to where the pointer goes for the next 30sec

hope this helps and thank you for any help
