Hi,

I think Pedro Lopes was implementing a Dynamic Time Warping external, which is a very common technique in pattern recognition... I don't know the state of the project, but since he presented it in the last PD-Con it should be in beta at least.

Dear PD-List

I recently decided to get into gesture recognition for several different performance-art purposes. one of them is for fireshows, where i would like to be able to control events on my computer throug the circling movements of torches. another one needs to be able to recognize simple gestures with the hand like swyping, cyrcling etc.

my question: has anyone worked with gesture-recognition? are there specific objects or patches? tracking-wise i would use an infrared-cam or wiimote-ir for the fire, for the hand-gestures maybe a normal webcam which films the hand only, on the side of my body.

big thanks for reading and any ideas or suggestions!

greets, matt

Hello,

I know there is time delay neural network (TDNN) for this purpose. So you can get the ANN externals. I know that it exists other methods but I have never tested them. ++

Hi all,

Indeed I have an DTW external, still need to find free time to get it there for everyone (as a working external, and probably only for linux - not enough free time!). Anyhow when I did my presentation at this year's pdcon, I did show easystroke as an example. Easystroke is absolutely fantastic, and the recognizer is robust for my usage (I have about 20 gestures that I use for more than a year, to control the OS). That would be an interesting take on the gesture recognition issue.

If your gestures are not multi-streamed (e.g., multitouch) you can also use on of the many 1$ gesture recognizer implementations out there - which is a very famous calligraphic recognizer. e.g., http://depts.washington.edu/aimgroup/proj/dollar/

hope it helps, Best, Pedro p.s.: regarding the DTW, I still need some time, but its definitely gonna happen. Although for calligraphic gesture detection it is very robust, I would go for easystroke or 1$.
