Head movements to turn page for organ players
#1
Hi,

this would be especially useful for organ players as they can't use a pedal to turn pages.
I know there is a Window app similar to MSPro where you can use head movements to turn pages.
Maybe opencv (opencv.org) could be handy for this?

What do you thinks?

TIA,

Frank

Maybe this is useful: AirTurn (not affiliated) has tongue and bite switches.

My Samsung P900 has settings that are used to detect whether or not you are looking at it - used to pause a video, or something along those lines.

Quite honestly, I've never even tried using them, but there might be something in there that would allow you to do what you require.

Interesting, indeed, but not practical here. Thanks

Yes, I remember that, but it is not very practical, and I doubt that it works with anything else than samsung's own apps. IRC turning your head away would stop 
the movie player and tilting your head down would scroll in the browser... But I'm not sure if this genrates a pagedown event that any app could receive.
Graeme, if you still have the stock rom on your Note, could you try if it works, please? 

Thanks a lot in advance,

Yes - it's stock.

I'll have a play with it later and let you know what I find. Never used it, so it's a new adventure for me as well Smile .

OK - had a look at this ..... forget it Smile . It's not going to be of any use at all (TBH, the whole face detection idea struck me as a bit OTT, which is why I never bothered turning it on to start with).

I doubt if there is a practical software solution and it's going to have t be some sort of hardware device. Not sure what - four manuals, swell and a full pedal board is a bit of a handful in which to throw another control element Sad .

I read up on OpenCV, and it looks like there are examples on how to detect head or eye movement. Might be a fun project to work on in the future, but due to the complexity, it will certainly have to wait for awhile.

Good luck with that!

Do you have a link to these examples? Would be interesting to have a look at how they work. Smile

I found a lot of information in various places. Here are some things I found just looking around briefly:

If you can neither use your hands nor your feet to turn pages (as it is the case for organ players) you might find ideas if you look around what is offered for disabled persons.
http://www.pageflip.com/usesPedals.html mentions "sip-and-puff" and "Jelly Bean" pushbuttons that can be easily connected to a common bluetooth pedal

MSP primarily mimics paper, so who turned the pages before MSP?

OK - maybe I was a bit tongue in cheek with that comment, but we are talking about a very limited market here and I suspect there are improvements/changes, that would be far more universal in appeal.

I would be happy to have a page turner solution without hands or feet. Head movement sounds like a promissing concept.

If you have an iPad, you can get an idea for how it works: (or doesn't) Piascore for iPad has the feature. In my experience, it is clumsy at best. It tends to assume your head turn meant to turn the page forwards even if you turned your head the other way. It is a good proof of concept, though. FWIW
