Recognising a certain gesture
Hi guys
I posted a while back about recognising a significant movement (gesture) and everyone was really helpful.
I now have a similar question regarding a gesture that is specifically right to left. Is the best method of recognising this gesture to monitor velocity? Or should it be a combination of monitoring gesture velocity and gesture position?
Or is it something completely different?
All the best

Hi
it would depend entirely on what kind of data you're getting (noise-level, resolution etc) but the simplest method for me would be to subtract a previous value from the current, then a positive result means decreasing input/numbers, and vice-versa:
But you said as much in your question :)

ooops
just saw the related thread you mentioned; the above patch doesn't really add anything new to the solution I posted there : {
With that patch you posted, can it be changed to only toggle on when the movement is really fast and the distance is about 50% of the scale?
Does that make sense?
All the best

You'll have to judge for yourself what constitutes "50%" as you haven't given us any specific environment variables, but you can set a threshold like this:

HI JOE
"I posted a while back about recognising a significant movement (gesture) "
---> could you tell me where your post is please.
Thanks so much

n00b, sorry I was being a bit unclear. I am getting a constant stream of x&y coordinates, but I am trying to get a bang when the velocity (which I have now set thanks to your addition to the patch) and the distance (ie the x coordinates which ranges from 0 - 320) is "significant". By that I mean the numbers for the x-coordinates quickly changes from a number like 300. to 30..
Does that make it any clearer or am I just talking nonsense
All the best,
J
Thank you JOE, it's kind of you
