The next step is to start interpreting the calculated gaze positions into a
switch activation. opengazer outputs everything to a port as it works, which
should make things a bit easier. Any suggestions on good assistive software
I can play around with? I hear there's this great "Jambu" thing... :)

in response to this from Stephen, if you need anything done on Windows I could write a socket application to listen for that port and then interpret the gaze positions     to detect for switch activationbased on the threshold method at first.  I might have the wrong end of the stick, but if any of this sounds useful let me know.

Hi Tom, I think that is the technique to use. The question I see is
what form it should take.

It would be great to have it integrated in Jambu (thanks Stephen).
That could be done by having it add events to the switch event queue
as got by Switch.getEvent()
http://www.oatsoft.org/trac/jambu/browser/trunk/src/Switch.py

Otherwise a more general purpose input device or adding synthetic
events to opengazer would work.

How do you detect switch activations? Dwell?

I was rather hoping you would say that :)

I think that directly integrating with Jambu is an excellent place to
start. A generalized virtual device approach can always come later
when we can prove that the concept works.

The question of detecting switch activations is an important one. Mick
Donegan's original suggestion was something like a threshold glance -
looking far enough in one direction fires the switch.

I think the quickest route to a basic proof-of-concept would be
something like this basic threshold technique, though I am sure there
are better options - ideally something like Simon's gestures idea.
Perhaps Mick would like to join in on this discussion?

Thanks Steve for suggesting Jambu here. From my perspective the main
goal now is to set up an environment for experimenting with different
activation options and Jambu sounds like a good options for this. Is
there an subversion repository I could check out to get started?

Sorry for the absence of any opengazer build-instructions. I'll write
them up today.

Hi Tom

Thanks for the offer of help on Windows. I'm sure that platform will
be a barrel of fun, so probably the first thing to investigate is
whether we can get opengazer built and running. I _think_ that most of
the dependencies can be built on windows, but perhaps we should see
what the author has to say.

Hi

It turns out the opengazer readme has been updated with answers to
most of the questions that I encountered, so rather than repeat what
has been written there I'll just point you on to the homepage [1] and
the readme [2]

[1] http://www.inference.phy.cam.ac.uk/opengazer/
[2] http://www.inference.phy.cam.ac.uk/opengazer/README

I can confirm that the apt-get installation of libcv-dev and all that
does work on ubuntu.

I found installing vxl a bit tricky as I am not familiar with cmake,
but the vxl page does a good job of expaining it:
http://vxl.sourceforge.net/releases/install-release.html

Just make sure to set BUILD_SHARED_LIBS to ON. I also changed
CMAKE_INSTALL_PREFIX on my system to /usr as I think it was /usr/local
which ubuntu doesn't include in its search for shared libraries.

also, I had trouble with the latest release, so perhaps use vxl-1.8.0
till you have things working.

I also found the Makefile quite fiddly in opengazer 0.1.1, but that
seems to have been improved in 1.1.2. The only thing I had to do was
change the VXLDIR to reflect that '/usr' prefix on my system (it is
set to /opt by default).

The rest is described well in the makefile. I imagine there will
probably be some hackery about the webcam. I found that I definitely
needed the

"sudo modprobe pwc size=vga"

line before anything would work for me. One more catch I'm afraid.
Ubuntu 2.6.20-16 seems to have removed the pwc driver, rather
unhelpfully (it wouldn't even build under ubuntu!). If you're using a
camera that requires this driver than roll back to 2.6.20-15 like me.
I think the next webcam I buy will have to be supported by UVC or
SPCA5XX or something else that actually works in ubuntu. I'll have to
investigate the driver issue more thoroughly.

I hope that helps a bit. Please respond with any problems you have and
perhaps we can figure them out. Personally, I'm learning a lot of this
as I go along so I welcome any feedback from more experienced linux
hackers.

Good luck!

OK will have a go! Though it'll be next week before I get a chance

The one sent at Wednesday, October 03, 2007 11:31 PM is as detailed as
I've written so far I'm afraid. I can mail you this directly if you
like

[Steve Lee-3]

svn access is http://www.oatsoft.org/svn/jambu/

e.g
svn checkout http://www.oatsoft.org/svn/jambu/trunk jambu

It's public readonly so I can add you when/if you want to commit.
Jambu is undergoing fairly high churn at the moment so you may want
work with me on merging later. Or we could create you a branch.

bringing in Simons comments on how it might work. I was imagining a
small JAMBU widget. This has 'target' cells too look at generates the
events to control applications. The current Firefox set is a
reasonable starting point. Threshold detection doesn't need
interaction with Jambu visuals and ties in with controlling apps
directly from devices with gestures, ,a long term goal of jambu's
capability pallette concept.

For this the work new code would perhaps get the display locations of
the cells (View.py), do it's gaze hit/dwell detections and input
switch events to jambu.

Transparency could be used to make it less obstructive if the user has
compiz or other window manager that supports alpha. A little tweaking
is need to ge tthis fully working.

Hello all,

I am new to the great opengazer Software and I found this thread via google.
Is there any news porting the software to windows?
I would really recommend it.

thanks a lot

cheers

[Stephen Emslie]

Hi Chris

I agree that it would be great to see opengazer ported to windows.
Personally I dont know how easy this would be as it appears to depend
more than one large library, but I've cc'd its developer so perhaps he
can tell us :)

I think the big ones are VXL and OpenCV, both of which seem to be
portable to windows.

Hi Chris, that's probably a question to ask the OpenGazer project directly.
We'd love to know the answer though as it would be useful on all platforms.

Hi all,

I don't know it it would be better to open a new thread or to post it here... :)

I tried to get opengazer work, but I get one error when I triy to make it:

Where should the missing files be?
Or to which package are they belonging?

thank you very much for any answer!

Cheers Chris

Hi Chris, I have no experience of the packages in question but Stephen
recently posted some notes that may help.

In general a problem like this can be resolved by the following

1) ensure the files are installed correcty - use 'find' to see if they
exist. Did you install the required dev packages?
2) check the build configuration is correct so the compiler finds them
(often through an environment variable called INCLUDE). did you need
to fun ./configure or equiv before making?

[Chris Feser]

thx Steve,

I tried several thnigs, but I couldn't get it to work.
Always the same error.

A "sudo find / |grep vnl_svd.h"
Answers with:
/home/chris/Desktop/software/vxl-1.9.0/core/vnl/algo/vnl_svd.h

but my compiled vxl is there:
 /home/chris/Desktop/software/bin
but there is no vnl_svd.h in it

When I run the ctest in the bin directory, every test passes except this one:
531 - vpgl_algo_test_camera_compute (SEGFAULT)

But this couldn't be the problem, could it?

My Makefile looks like this:
# required libraries: vxl, opencv, boost, gtkmm

VXLDIR = /home/chris/Desktop/software/bin
VERSION = opengazer-0.1.2
CPPFLAGS = -Wall -g -O3
LINKER = -L$(VXLDIR)/lib -L/usr/local/lib -lm -ldl -lvnl -lmvl -lvnl_algo -lvgl -lgthread-2.0

# change the following line if your vxl library is installed elsewhere
INCLUDES = $(foreach prefix,/usr/local/include $(VXLDIR)/include $(VXLDIR)/include/vxl, \
        $(foreach suffix,/core /vcl /contrib/oxl,-I$(prefix)$(suffix)))

# -I/usr/include/ffmpeg
# -lcv0.9.7 -lhighgui0.9.7
# -lvgui
....

I tried
VXLDIR = /home/chris/Desktop/software/vxl-1.9.0
because there are the header files, but it didn't work neither.

What do I do wrong?
Thx for any idea...

Cheers
Chris

Hi Chris

Just a quick stab in the dark, but did you compile vxl with the
"BUILD_SHARED_LIBS" flag on?
