Re: [Wlug] Need some help with digital signal processing ...

by David Glaser

Tim, After your feedback and feedback received during theWLUG meeting, it seems that it is better to use something like an Arduino instead of a phone as the signal processing box. To that effect, I googled "arduino dsp" and got a whole lot of hits on DSP shields for arduino and on projects that illustrate how to write arduino sketches that manipulate the stream. One possibility would be to have an Arduino with a DSP and a bluetooth receiver. The bluetooth would communicate with a phone and/or a wearable. The phone would tell the arduino what sounds to look for - that is, provide signatures that should be matched. The wearableand/or the phone would be used to give the event to the user. I think that this configuration along with a battery could be configured to fit in a small fanny pack. The arduino could also use zig-bee to communicate with a home automation system and pass events to the phone/wearable. Hmmm, I think we are on to something. -David On 12/12/2012 08:33 PM, Tim Keller wrote: > I would have to imagine having your phone listen to ambient sound and > then filter looking for a whole range of specific sounds is basically > going to use all the phones processing power along with its ram... > > I have to imagine that not hearing the beep when the oven is done pre > heating must be annoying > > Not hearing the washing machine or the clothes dryer buzz would really > piss me off. > > imagine a box.

I would have to imagine having your phone listen to ambient sound and then filter looking for a whole range of specific sounds is basically going to use all the phones processing power along with its ram... I have to imagine that not hearing the beep when the oven is done pre heating must be annoying Not hearing the washing machine or the clothes dryer buzz would really piss me off. imagine a box. On this box would be al led screen where you could cycle through a menu and pick a input to listen to and report when either that input starts or stops. In the case of a clothes dryer when the vibration sensor stops sensing vibration, chances are good it's done. This box would also have plugs for things like a photo sensor you could stick on the face of your stove right over the led for preheating the oven. All of this stuff could be tied back to your phone that would vibrate and sent an sms message. Possibly you could tie it in with a home automation system to flash lights, etc. Just some ideas. Tim.

Re: [Wlug] Need some help with digital signal processing ...

by David Glaser

John, As a fall-back, I am considering going the Arduino/ZigBee route. You can buy ZigBee doorbells, etc. However, this requires a fair amount of installation/wiring that needs to be done to the house. I lost my hearing during my middle ageand I was given a box full of signalers by the Commonwealth of Mass. Hooking up these signalers is not the easiest of tasks and I was hoping to bypass this via having a wearable computer do the recognition. (BTW - I have a Cochlear Implant that obviated the further need for the signalers). -David On 12/12/2012 03:21 PM, John Stoffel wrote: > Doing DSP in your phone or other android device might become really > difficult, really fast.

Doing DSP in your phone or other android device might become really difficult, really fast. In any case, I'd recommend that you get one of those development boards which runs Android and work with that to start. No need to sacrifice your phone ahead of time. Also, instead of listening for sounds, maybe you can wire up a dedicated device into the home which would talk directly to the haptic device or the glasses? My brother went to RIT (Rochester Institute of Technology) and they have a large deaf population there, to the extent that some dorms are fitted out with the bright stobe lights used to wake/alert deaf people of fire alarms, etc. Listening for arbitrary sounds and trying to match them to a library of triggers sounds (sorry for the pun) like a very hard problem. Even apple is doing Siri by sending your speech to a remote datacenter for processing, since the phones don't have enough juice. Admittedly, that's a more difficult problem space, but it is similar and less open ended than your problem space. Just hooking an Arduino into my doorbell/phone/other sensors and having the arduino talk to the alerting system might be a simpler way to do it. John

Announce: Meeting December 12th 7PM, WPI Campus Center Mid-Century Room 331

by Chuck Anderson

We are having a WLUG meeting this evening, December 12, at 7:00 PM in the WPI Campus Center, Mid-Century Room 331. http://www.wpi.edu/Admin/CC/Floorplans/37678.htm This seems like a good time to talk about the WLUG website. We've had half-completed plans since about 2 years ago to replace the hardware and software to create a Wiki or Drupal site to replace the outdated and manually-maintained-by-me HTML site. This week I plan to finally migrate things over to the new server, but the content will still be the old HTML site for now. We need some volunteers to help build a new site in either MediaWiki or Drupal or some other framework. After the meeting, we'll continue discussions over at Tech Pizza. Hope to see you there, Chuck

Need some help with digital signal processing ...

by David Glaser

Hi Folks, I need some help with an Android app for the hearing impaired. Essentially, the app is to be used with a wearable android device (Google Glasses or theSony android wrist watch) and will listen for sounds such as the door bell or the tty, or any other household soundthat should be reported to the wearer. Capturing the sound using an Android device is not the problem. What I don't know is how to compare the incoming sound stream with sound signatures that should cause the event to occur. Once the event occurs, then text can be displayed on the googleglasses or the haptic transducer on the wrist watch can be activated. This app is intended to be open sourceso I'm looking for volunteer help on the algorithms. I will do the programming. Regards David Glaser dglaser(a)glaserresearch.net

I looked into the stylesheets in Gates of Madness available from: http://www.wizards.com/dnd/Feature.aspx?x=dnd/feature/abyssalplague I find: .calibre { Either they used calibre to do the conversion or someone made it look like it. Maybe I shouldn't have discounted the idea.

Re: [Wlug] Ebook Creation

If you are just doing text already, you should really check out pandoc. It converts different "text only" formats to different other formats. Markdown is the new famous "readable as plain text, parseable to fancy text" on the block, but pandoc supports a few other very famous ones. If you just do a bit of ascii beautification, you can end up with something that you can read and edit it just by itself. No reveal codes, no show source, no XML. Just simple text. Check out the example on pandoc's website: http://johnmacfarlane.net/pandoc/epub.html It even has a link to the progit github repo where you can see how well it worked under version control. You can see how a chapter looks and look at the build process that they use to make it. Here's chapter one in the raw markdown: https://raw.github.com/progit/progit/master/en/01-introduction/01-chapter1.… very readable. With github's built in markdown to html converter, it ends up like this: https://github.com/progit/progit/blob/master/en/01-introduction/01-chapter1… Once you have it in markdown or reStructured Text, you just convert to epub. From there you use KindleGen and you have .mobi which works everywhere that epub doesn't. The other option is to write your own rules for the calibre text to any-ebook-format-ever converter. You end up with not having to change your format at all, and calibre is made for ebooks. It doesn't try to do anything else. A true one trick pony - the Unix way. Also, everybody knows that epub is just a zipped up set of html files with like 3 xml files, right? Change any .epub to .zip and you've got a little archive that you can poke around in. Yoink pictures, fix typos, diff between versions... Open formats FTW!

If you create a particularly formatted *.doc file in Open Office, Amazon will convert it to Kindle with their online tools. The tricky part is getting the table of contents and footnotes correct and "clickable". My wife did manage to get it to work. She used Neo Office on Mac. https://kdp.amazon.com/self-publishing/help?topicId=A328FYMFAE7VNY#word https://kdp.amazon.com/self-publishing/help?topicId=A17W8UM0MMSQX6 Knowing what I know now, if I were to do a book, I would definitely do the work of writing in a simply structured ASCII file in source control. I would have the title, author line, chapter headings, and section headings on separate space-separated lines and the content in discrete paragraphs without hard line breaks. Then, for the e-book, I would drop it into Open Office to do the formatted doc file for Kindle, or the formatted RTF file to feed Calibre for e-pub. For the print version, I would paste it into Lyx, set the page size, go through it to change the style types for the author, chapter heading, etc, and then render it to PDF. If I had more programming and format conversion knowledge though, I think that the best method would probably be to write the book in XML, e.g. DocBook, and then use code to generate the above doc, RTF, and Lyx/LaTeX files. -Adam On Mon, Dec 3, 2012 at 4:11 PM, <dulsi(a)identicalsoftware.com> wrote: > >> Quick question...

True patriots will accept no substitutes. If you need a lot of pictures you would need a way to embeded them. If you need the occasional bold or italic, a tiny subset of HTML suffices, and remains readable even as Ascii. Are E-books being sold that can't display Ascii? I don't have an E-book, and it's going to stay that if they don't display Ascii, at least. If you are speed writing, I would think you would stay away from "formats" and just send the octets from the keyboard to the disk and out. -- Keith PS: Not a total curmugeon, I will take Unicode.
