webcam mouse movement = mouseTrap

[Flavio Percoco Premoli]

Greetings!!

I'm working right now in a new project called mouseTrap. It is based in
at-spi and OpenCV libraries using the python programing language.

mouseTrap is an accessibility application to move the mouse pointer with
a web cam and face detect features without using the mouse or keyboard,
it  will use the eye track too (working on it ) so there wont be no need
to move the head.

I'm trying to install the vxl library which gives me a compiling error
(any help??) to test the opengazer features and so implement them in
mouseTrap.

Well, I won't bother you with a long mail, here are the demo links:

The first one uses a complete face detection (with require a lot of CPU
usage), the second one is the one that uses the latest improvements
where i changed the complete face detection for a point tracker (less
CPU Usage). Well, I'm working on it, and i hope you like it.

Hi and thanks Flavio, that looks pretty smooth.

There are some here who have managed to build OpenGazer so may help.
Can you supply specific errors you are getting?
Plus there was a discussion which should be in the archive.

Sure!!

I'll read the complete discussion.

This is the error I'm getting:

I know it is the beta1 but even with the stable i get the same error :(

Hey Flavio,

That is fantastic!!!

Should you be linking up with

http://blogs.sun.com/wwalker/entry/low_cost_control_of_the

(from a mail from Steve a while back)?

I assume since you are using Python and OpenCV it will be able to work
across operating systems?

I look forward to playing with this, in fact, I'll do it now!

Cheers.

Simon

Oh no, I thought the links were binaries! I can't play with it!

Videos look good though.

That's the same Flavio in both cases Simon ;-)

I spotted pyatspi (great) is used which is GNOME only, but IA2 reduces
the gap evenif no python binding yet.

@Flavio: where does pyatspi get used, just for selecting useful
windows to auto-focus?
Can we look at the code? Don't be shy about it not looking too neat.
It works well and polish can follow. ;-)

Cheers

Steve

Looks like a great project Flavio. If you're kind enough to make the
source available then perhaps we can try to build it on our own
systems.

[Flavio Percoco Premoli]

Hey guys!!

Thanks all for your Opinions and motivations, I'm really glad you all
like the project.

@Steve:  where does pyatspi get used, just for selecting useful windows
to auto-focus?

Well, pyatspi is used for several things:

1) Mouse movement listener
2) Keybindings listener
3) In the widgetsTrap feature is used to get all the selectable and
focusable widgets.
4) Execute the movements of the mouse

It would be really nice to create mouseTrap as a multi-platform
application so I/We could think in a way to reduce the use of pyatspi
which is the only library that isn't multi-platform in the mouseTrap
API. I don't know IA2 so I'll take a look at it immediately. :)

I've no problems to share the code with you so I'll create an svn under
my domain and I'll create a private project for mouseTrap. I'll send you
the username and password that will allow you to download the code. The
user and password is because I don't want to make it completely public
until a first version can be released :P (Nothing to worry about, I just
want to do a great job :P )

I'll added a file in de source called TESTS with a list of things that I
would like you to test ( If you can, it is not obligatory :P ) to know
how mouseTrap works in other computers and architectures.

Right now, My first goal is to reduce the CPU Usage and improve de
facedetection (reducing time and producing best results ) just after
this, I'll get to work in the mouse click execution ( Ideas are
welcomed, I'm thinking to use the eyebrows up/down movement or the eyes
blink ). I'll be making a lot of changes in the code this days. I'll
keep you all in touch.

@Simon: How can I add the project to oatsoft? I logged in but I don't
know where I shoud add it.


Well, I think this is it for now, I hope we can share many ideas and
knowledge.

Again thanks to all.

P.S:  Right now I don't remember if i sent this link [0] to the list. So
I send it again. Feel free to give your opinions too.

P.S 2: I'll send the svn info tomorrow, today I had to travel and my
bateries ran out of charge :P

P.S 3 and hopping it to be the last P.S :) : I would like to work a
little bit in the arts of mouseTrap, I completely sucks creating images
with gimp or inkscape so as I said before, and help is welcomed.

Have a nice day

Hi,

To add a project, click 'add oats' from here:

http://www.oatsoft.org/Software

HowTos:
http://www.oatsoft.org/Info/HowTos/SubmissionGuide
http://www.oatsoft.org/Forge/Info/ForgeFAQ/how-do-i-manage-my-software-relea
ses-on-the-oats-site
http://www.oatsoft.org/Forge/Info/ForgeFAQ/how-do-i-use-my-forge-pages

I think there might be a permissions problem at the moment with adding
releases, let me know if there is a problem.

RE clicking:  you would make me a very happy man if you could produce a
click from a blink. I have been prodding/looking for something that JUST
does this for ages.  Occasionally we have clients who can only blink, or
maybe just move a muscle to raise their eye brow. It is VERY hard to get a
physical or EMG switch to pick this up, a video based switch (i.e. something
that triggers off a blink or small movement) would be GREAT!  

Nowadays we might use eye gaze for such a person, however I think such a
video-switch would still have uses (e.g. people with problems with eyes,
people wanting simple systems, people wanting a backup method of access....)

Anyway, keep up the good work, look forward to playing with the
binaries/tests when I get a chance.

Cheers.

Simon

Cheers.

Flavio,

 http://www.flaper87.org/2008/05/21/mousetrap-an-accessible-control-of-the-mouse-via-web-cam

looks to be a really exciting project.

had you tried this with os x**?

the avi demo does not work for me using

ppc 10.5.2

quicktime Version 7.4.5 (25)

the video downloads and plays ‘white-screen’ with no audio.

**I filed a bug enhancement with apple when they introduced the webcam in laptops, along these lines…

comments posted there..

cheers

getenv is declared in stdlib.h (C) or cstdlib (C++) and that is not
explicitly included in the testlib_main.cxx which IMHO is a bug. My
Guess is that on some systems it gets included indirectly via the
other includes depending on conditional compilation.

hmm, interesting, how so as you are simulating the the mouse?

I guessed that, I wonder if driving X might be better in the long run
but don't know the issues. Will Walker has worked on X and pyatspi so
may give us some info.

Yes that is currently the platform dependent bit if you use UI widget sets etc.
IAccessibile2 basically extends MSAA on windows to be very similar in
semantics to AT-SPI.
For now you need to create other code and no one has yet done it
(though NVDA uses IA2 with Python).
A port of pyatspi to 1A2 has been dreamed about ;-)

Yeh I know the feeling. Sometimes it good to overcome that and release
early as it can save you work in the long run if some spots something
or has an idea ;-)

will do :-)
