Comments on: OSC, processing and an iphone accelerometer http://www.codingnature.com/osc-processing-iphone-accelerometer/ The creative endeavors of Tor Guttormsen Fri, 26 Feb 2010 04:06:34 +0000 hourly 1 http://wordpress.org/?v=3.0.4 By: Dave Pentecost http://www.codingnature.com/osc-processing-iphone-accelerometer/comment-page-1/#comment-26 Dave Pentecost Fri, 26 Feb 2010 04:06:34 +0000 http://www.codingnature.com/?p=223#comment-26 Finding this has been a big help - I have been thinking of a similar use of Processing (except in my mind it has spheres instead of cubes, and a live video signal) and this was a perfect headstart. For others who are trying this, I would only add that the OSC messages coming out of the TouchOSC app are pretty well documented in the pdf you can find on the TouchOSC page: http://hexler.net/software/touchosc There is also an OSCulator file on that page that can be opened in OSCulator and you can then use that app as a kind of OSC "sniffer" to watch for the messages that come from TouchOSC. http://www.osculator.net/ Finally, there are some Processing sketches there that will help in using TouchOSC and OSC in general. Thanks again.

Some very interesting and creative data visualizations with excellent visuals. Thanks :) I checked out your site and must say I really like what I see.

Gonna check it our tomorrow... Some nice stuff on your site btw. Saw your data visualisation from this month, it's quite impressive :) Yeah thanks!

Basically those floating values are a measurement of the G-force being applied to the axis in question. Hope that helps :) Hi Sander,

I can understand that 1 of them has to do with the X-axis, one with the Y-axis and one with the Z... But I would still hope you could tell me some more about what the actual values really mean.. again, thanks in advance! sander After looking at your source code, I saw there are actually 3 values coming in with that OSC message.

Seems to work like a charm eh? I was just playing around with my iPhone and tried to get in the values from the accelometer. I've done some other stuff with (Touch)OSC + iPhone + Processing, so reveiving data was no problem. But I was just googling around to see what the values exactly mean. When i println them, it seem to be all floats from -1.0 to 2.0? So, while googling I came across your site, and you obiously seem to know what you're doing, hence the question: What are the values coming from the iPhone Accelometer? And what can I extract from them (movement, iPhone positioning?) Thanks in advance! Hello there,

I'll go ahead and email it to you as well. I had hoped to have some time to write up something of a tutorial on this, but I have been very busy with school and other projects lately so it has sort of gone on the back-burner (sorry, Patricio). I still hope to get around to it at some point in the not too distant future. For now, If you (or anyone else for that matter) have any questions about the source code or anything else, be sure to let me know, and I'll try to help out as best I can. Hi Ben,

Many thanks, Ben Really impressive stuff, I’m just starting out with OSC and processing after discovering reacTIVision and Abelton, I’d love to have a go using my iPhone too but don’t really know where to start – any chance of sharing the source?

But, i don't understand who to communicate with processing. Is very frustrating being a designer and not a developer... :( You really want to do a tutorial based on your work?
