Re: [PD] Pd applications for the blind or other disabled
Hi... I've done this patch few months ago : http://yamatierea.org/papatchs/#1-terface It's an interface for people who can just push one contactor (with the chin for exemple). You can choose the number of the lines, columns, the cursor's speed an have a specific action for each square. I've also worked with blind people, and as this sequencer ( http://yamatierea.org/papatchs/squareroom/OSR.htm) can be used with gamepad it's possible to compose (and make animation) without the screen. It had not been made for, but it was fun... :-) With cranial trauma, I've use this one ( http://yamatierea.org/papatchs/#detc-mvt) for them to make music with their movements. It could be use with blind people. Hope it'll be usefull.

This will also mean that any unmatched message with no path leaving the rightmost outlet will have '/' set as its path. The only snag I foresee is if the first element of an incoming OSC is a string beginning with the character '/'. In that case it will be mistaken for a path. And also the wildcard code needs fixing up... Thanks for pointing out these issues.

Sorry; that was intended as a joke -- a deliberate ambiguity between
zero ("the number zero"), zero ("the set with zero elements"), zero
("false"), and zero ("number of numbers which are 'directly
perceivable'"). It was late, I thought it was funny.

"Pair" is a word of English, and a highly ambiguous one at that -- it
might be an ordered pair, an unordered pair, a pair of pants, a pair of
aces, 'a pair' (aka "couple"), or whatever. Yes, it's semantically and
pragmatically complex. The (abstract) number "2" plays a pretty heavy
role in all of its sense I can think of at the moment, though.

What about them? They're usually related by quite simple and obvious
rules (e.g. 'add/delete an "s" at the end') except for a very few high
frequency lexemes. I agree it's interesting that number (the
grammatical feature 'number', i.e. singular/plural) is explicitly
encoded in the vast majority of human languages (even in English, which
encodes almost nothing else from the known spectrum of grammatical
features), and that it usually plays a role not just in morphology (word
formation) but also in syntax (sentence structure -- think subject-verb
agreement in English); but I'm not sure what you're getting at. Do you
mean the semantics usually associated with the feature (singleton vs.
non-singleton set) -- it's kinda cool that zero tends to get lumped in
with plurals in English (but usually not in German); not sure how other
languages go about that one (but I have solicited some references from
an acquaintance who worked on numbers and number features pretty
intensively a few years ago...)

I think I see what you're getting at, but I'm not sure where it's going.
I'll accept the "directly perceivable" term for current purposes, but
there's whole heckuvalot more going on in our heads (brains & associated
processes) when we look at and identify a small set of like items as a
set-of-N than I'm accustomed to calling "direct", and that's just the

It's a unary predicate, i.e. an intransitive. It takes a single
argument. It returns a truth value; albeit in at least one common sense
of 'exist' that value depends on the evaluation index (possible world /
place and time of utterance / speaker / etc). I'm talking about the
kind of existence which is independent of the current index, i.e.
__necessary__ existence: existence in every possible world.
Sorry, that was probably annoying. Yes, different people use the word
in different ways with different connotations.

Sorry, I don't buy that. My two main problems with that sort of hardcore empiricism are (in a nutshell) ego (aka "consciousness") and will. To paraphase the ol' p-ant hisownself, 'where does the "I think" come from which can be prepended to any proposition or perception I'm currently entertaining?'

I think we're probably bound to to disagree on this, and that's fine by me, but just to be precise here: No, in my version there's an FSM called "42" floating around __independently__ of physical laws and processes.

By your logic (if I'm reading it right), there can be no such thing as a universal Turing machine *because* its ability to simulate itself prevents its very existence. But a universal Turing machine is really not all too hard to define (Turing, 1937): sure, we can't say whether or not it __terminates__ for itself, but that's a problem with *computability*, not with existence. We may at some point actually define a `perfect' computational model of reality, we just won't be able to prove it, since at that scale the map will have become indistinguishable from the territory. marmosets, Bryan -- Bryan Jurish "There is *always* one more bug." jur...@uni-potsdam.de -Lubarsky's Law of Cybernetic Entomology ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list

Re: [PD] Extended View Toolkit
Hello ignacio! the ev_vid.pd abstraction already has an outlet that bangs out different video properties. in order to keep the number of outlets managable we did not just forward the [bang] which is produced by [pix_film] when the end of the file is reached, but rather sending out the message [end( so basically if you want to use the outlet of [ev_vid] to trigger some external processes you could achieve this by using [route end] for example, having route connected to the outlet of [ev_vid] However i discovered a bug in the ev_vid abstraction, that is due to the realtimer part, which manages fluent video-playback even when the computer is under heavy workload. With this mechanism, pix film gets a float number, telling the pix_film object, which frame it has to "play". unfortunately this somehow disables the "bang when end is reached" function. I couldnt find out, why that is, but i fixed it in the abstraction. you will find the fixed abstraction (incl adopted helpfile) attached in this mail. simply replace the ones in your EV_Toolkit directory with the new ones. with this the workflow to get the [end( message would be as described earlier: [ev_vid 0] / [route end] / [bang( feel free to ask if something is not clear. enjoy, peter Von: "Jose Luis Santorcuato" Gesendet: 21.05.2011 06:19:37 An: "Ignacio Aguirre" Betreff: Re: [PD] Extended View Toolkit Hi, in GEM the object pix_film delivers a bang when the last frame is reproduced, when the movie ends bang to [1 ( and starts the others videos...also you can bang a zero and stop the current movie.

Thanks for your time guys! hope to let you know soon about mi thesis made with pd and kinect. Hello All! I want to announce the official release of the Extended View Toolkit. http://puredata.info/Members/Weitsicht/extended-view-toolkit/[http://puredata.info/Members/Weitsicht/extended-view-toolkit/] The Extended View Toolkit is a set of abstractions developed for the art installation "Extended View streamed". It is intended to be an easy solution to experiment and realise panoramic video and complex multiscreen projection environments to createimmersive media experiences. It features a set of abstractions that are able to combine multiple related image-sources (like video input, video playback) into aconsistent panoramic image. The source-material, e.g. the camera to display has to be aligned horicontally, since image-combination is based on simple, openGL basededge-blending and not algorithmic pix by pixel comparison. Furthermore it features abstractions to create multi-screen, multi-projector environments to enable correct representation of (not only)panoramic material. The projection abstractions can be combined to form big screens out of multiple projectors with softedge betweenoverlapping borders of single projectors and contain a vertex model that can be adjusted in 4, respectively 9 points, so that projections onchallenging geometric surfaces is possible. Additionally, all abstractions are controllable via OSC-styled send/receive-messages, which simplifies OSC-based external control. Also, since streaming video was part of the project, a gstreamer based streaming solution was developed by Peter Innerhofer to distribute panoramic/multistream video over network. It can be found here: [https://github.com/peonic/streaming[https://github.com/peonic/streaming]] Libraries needed: mrpeachBuilt with pd 42.6 and GEM 92.3 Credits: Shader Programming/openGL: Cyrille Henry GEM: Marian Weger Prototyping/GEM: Peter Venus Streaming: Peter Innerhofer Initiation/Supervision: Winfried Ritsch A short demo-clip can be found here: [http://vimeo.com/20311051[http://vimeo.com/20311051]] The project was made possible through support from IEM-Institute for Electronic Music and Acoustics (iem.at[http://iem.at]) and CO-ME-DI-A.

[PD] Where to find comprehensive documentation about Firmata
Hi, This is probably slightly OT, but I am using Pduino and I guess some of you can help me find complete documentation about Firmata, especially about how the StandardFirmata firmware is expected to work. For example I was looking for the details of how the "set pin mode" message works, and I've not been able to find them. At arduino.cc I only found the reference of the Arduino's pinMode() function, while at firmata.org the most I could find was: * set pin mode(I/O) 0xF4 pin # (0-127) pin state(0=in) without even a list of existing pin modes. I guess there must be some documentation somewhere that explains the semantics of each Firmata message and how exactly the StandardFirmata firmware is expected to behave in response to each message...

It would be interresting to see if proprietary software runs better. In the blender osx faq : How can I get Blender running faster? OSX Aqua uses OpenGL extensively for drawing, so it might happen your 3d card doesn't have sufficient memory to draw accellerated with a larger window size. A solution that works well, is switching to less screen colors: set the menu in "System Preferences -> Displays -> colors" at "thousands of colors". Another common issue is with using the Dock on top of the Blender window. This kind of transparent blending takes a lot of 3d card drawing powers, and can better be avoided by setting the Dock to become auto-hide. -- Charlot ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list

Use the non-old messages now. What are the non-old messages?

Also, check the PCIe lane speeds and try running them at 4x or 8x rather than 16x. AS far as getting 4 of the same cam running, it depends on how the driver presents multiple cams to Quicktime.

So, to access only the 2nd camera, I had to create two objects and only use the 2nd one. using 4 [pix_video] objects for 4 cameras may work, but they will be assigned by creation order. ___ | Mathieu Bouchard tél: +1.514.383.3801 Villeray, Montréal, QC ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list
Re: [PD] four PS3 Eye on Mac Pro and Pd-ext and GEM
Hello Chris, If I have time to do this test the next time i will do it (putting the graphic card on the 4x PCIe bus). Now, it works fine with 2 MacPro (with one graphic card and 2 PS3 Eye on each MacPro) and Ubuntu 10.04. I have installed PureData 0.42.5, last GEM from SVN and ATI driver Catalyst for the Radeon HD 5770 and the acceleration is OK. When i was using 'dialog' message, i can't remember what i got. Thanx for your help and suggestion. I will try to test all your recommandations the next time. One remark : it seems the graphic acceleration is better under Ubuntu than MacOSX. Is there a problem with the driver under MacOSX ? (The same patch worked faster under Ubuntu). ++ Jack > Jack > > I think two of those cards might draw too much power to run at the same > time?

[PD] Pd applications for the blind or other disabled
Hello, I wonder if there exist any examples of applications developed with Pd (from simple patches to externals or libpd-based stuff) aimed at rehabilitation or human-computer interaction for disabled people. I'd be very interested in any examples on this matter. Best, Stefano ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list
