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

Jeff, I will look at reddit forums. However, I am hoping for someone local for beer and pizza based information interchange. Face to face bandwidth is really fast. -David =================== From: Jeff Moyer <jmoyer(a)redhat.com> Date: Wed Dec 12 08:33:35 CST 2012 To: David Glaser <dglaser(a)glaserresearch.net>, Worcester Linux Users Group <wlug(a)mail.wlug.org> Subject: Re: [Wlug] Need some help with digital signal processing ...

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

Re: [Wlug] Ebook Creation

by dulsi＠identicalsoftware.com

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.
