New Post: Website Recording + Dual Monitor Setup

When trying to record a website slide, on replaying the experiment from the replay module, the eye gaze is displayed, but no background of what the person is seeing is shown. On the other hand when recording the desktop slide, the background is shown on replaying. Do I need to install some software for website slides?

Also, no dual monitor functionality was available, and after installing K-Lite Mega Codec Pack, this functionality became available, but on recording, the application keeps on crashing. Do I need to install other software?

Thank you for your help

New Post: Problem with AVI Export in Replay Module

Hello,

I just started using Ogama to analyze some eye tracking data from a recently completed study, and I have not been able to get the "Export to avi" function in the replay module to work correctly. We have chunks of eye tracking data about 8-12 minutes in length, and I need to be able to export a video of that entire duration. However when I try to do this, Ogama only exports a small portion from the beginning of the data to the .avi file.

After I click the "Export to avi" button and click OK on the options dialog, a window appears in the middle of the screen which says Ogama is rendering the video and displays a progress bar at the bottom. But after a short time, and while the progress bar is only 5-10% filled, that window just disappears. Opening the .avi file which Ogama has created confirms that only a small portion of the replay has been exported. The actual amount of the replay which Ogama exports before stopping seems to be random, and I have observed the duration of the resulting video to range from about 10-40 s. But in all cases, the .avi file is much shorter than the full replay.

I have tried all of the different video compressors listed in the video export options dialog, but the same problem occurs regardless of which one is chosen. If anyone else has encountered similar problems, or has any ideas of how this issue may be resolved, I would greatly appreciate your insights.

Thanks,
Kevin

Hi Lindadeleeuw, would you please explain better your method?

I am having troubles with AOI import from a file to one other (actually, two slightly different version of the same experiment).
The import process is successfully and Ogama is able to calculate stuff relative to the imported AOI. Though, the AOI module gets stucked all the time with an error:

The entered value is violating columns argument rules.
For example: the given value does not matches the columns type

I tried to vary the table structure with no results at all.

Thanks!

I am also having the same problem using Ogama with the Eye Tribe tracker on Macbook Pro with Bootcamp Windows 10.

For me the replay window also freezes after playing back a short amount of video, although the video will start playing again if I move the play head forwards and start again. However the video always freezes when exporting to avi.

Could this be a problem with how i'm exporting my videos to .swf? I'm using adobe media encoder to go from mp4 to .flv and then flash cs6 to go from flv to .swf

This fixed the problem for me:

I downloaded this codec pack: http://www.free-codecs.com/k_lite_mega_codec_pack_download.htm

the installer uninstalls outdated codecs and installs the ones required to play the avi files OGAMA puts out. The replay window also works and the output works the whole way through.

Not sure if this will work for you. My issue is I'm using bootcamp Windows so didn't have anything installed.

Do have a new problem which is that the spotlight/other visulations of the data move les/more slowly than they do in the replay module. presumably theres a setting somewhere I need to change. Any help with this?

New Post: How to install Ogama V5 - sqlite problem?

Hi,

I am upgrading to Ogama V5, but cannot get it to work. I have not been ble to find any installation instructions - what should I do to install successfully?

I have:
1) Uninstalled Ogama V4.5
2) Uninstalled all MicrosoftSQL applications and related files.
3) Downloaded the latest version of SQLite from https://www.sqlite.org/2016/sqlite-tools-win32-x86-3120000.zip.
4) Created a 'C:\sqlite' folder and unzipped here - including the 'sqlite3.exe' file.
5) Added sqlite to path on the commnd line 'SETX /M PATH "%PATH%;C:\sqlite"'. I can call sqlite3 from any directory on the command line.
5) Downloaded Ogama V5 from http://ogama.codeplex.com/downloads/get/1456939
6) Installed 'OgamaSetupV5.msi' without any error messages.

Ogama starts up, but when I try to create a new study I get a:

"Connection to SQLite database failed.
Take a careful look at the database file to attach and its path. The .db file should be named the same as the experiment .oga file and located in the Database subfolder of the experiment.
The error message is:
unable to open database file"

Where do I go wrong?

Thanks

Hi John,

the steps 3 to 5 are not necessary to run Ogama, it has its own sqlite access dlls.
I´m not quite sure wether the installation of the 2016 sqlite tools may break ogamas own sqlite connection.

The error message indicates just what it says, the connection to the newly created database (by default PERSONALFOLDER\OgamaExperiments\Experiment1\Database\Experiment1.db) fails because sqlite could not open this file.

I can think of one of the following reasons:
1) The file is not there (for what reason whatever)
2) The file is there, but ogama has no rights to access it (no admin, network storage, ...)
3) The file location is not URL compatible (special characters, spaces, >255 characters)

Hope this helps, regards,
Adrian

Hi Adrian,

Thank you for a quick reply!

This helped me solve the problem and I can now design and record :-) The error arose from access rights I think: I used the default folder proposed by Ogama in My documents (the same 'OgamaExperiments' as in V45). Ogama seems to write all the files and folders (including the Experiment1.oga file), but then has problems accessing the database. When I put new experiments in e.g. C:\temp there are no problems.

Great that V5 does not need the heavy SQLEXPRESS installation anymore. It will be much easier for my not-so-IT-savvy students to install and use Ogama with EyeTribe now.

Two suggestions:
1) Maybe add a note on installation of V5 saying that all necessary files are now included in the installer. There are several places where the old instructions are available and some people may try to do all that in case of errors like mine (e.g. https://www.youtube.com/watch?v=yL9t-bPGalE)
2) For the specific error message maybe add something like "Try saving the experiment in a different location"

Thanks for all the work on V5 - I look forward to using it!

Best

New Post: Stopping flash video (swf) stimuli?

Hi,

I have a problem stopping flash video (*swf) stimuli: If I set the time a video takes (e.g. a video of 2:04 = 124,000 ms) the video does not stop after 124 seconds - instead it loops and starts over. Even when I set a shorter timer e.g. 15000 ms the audio continues on the next slide.

Is there a good way to make video and sound stop at the same time? I had the same problem in V4.5 also.

Thanks

New Post: Reaction Time

Hi there,

I'm hoping someone can help me.

I have programmed a slideshow task whereby pictures appear with a text question underneath. I have the test response as specific keys (Y for yes and N for no). I was wondering if there is anyway to calculate reaction time using this software? I.e. the amount of time it takes the participant to hit Y or N from when the picture is first presented on screen? I can't seem to find an option to export this information when analysing.

Many thanks,
Alex

Hi Alex,
you are right, there is no time information on the key responses in the statistics module. It would be relatively easy to implement this using the sources and I put this on the wishlist. In the meantime it might be a workaround that you look at the database module at the trial events table. There is a column called event time with the time until this response (e.g. key press) happened counted from the beginning of the trial. You can export this table also.
Regards,
Adrian

Hi Adaszem,
the tobii license policy did not allow us to deliver an interface with ogama for this tracking device, even if it would be possible to integrate.

New Post: Time stamping Fixations

Hi Adrian,

I was wondering if you could help me with the following query:

I have recorded eye-tracking during a 2 minute video and have drawn an AOI over a certain part of the video that I want to know: total looking time and number of fixations. However, I only want to know this information during certain points in the video- so for example I want to know the number of fixations and total looking time within that specific AOI from 1 min 46 sec to 1 min 49 sec. Is there a way that I can time stamp all of the fixations during the 2 minute video and then manually chose all of the fixations that fall within the time period that I am interested in?

Hope that makes sense! Please let me know if you require further clarification.

Many thanks,
Alex

Dear all,

I have just found OGAMA and would like to play a little bit with it. I took a look to the documentation, but I have some questions. In my research, I like to represent eye tracking data with heatmaps. These heatmaps are filled with the z-scores of the number of fixations. This allows direct comparison between conditions. I was wondering whether it is possible to do this with OGAMA.

Thanks!

Hello,
I write here because I have to do tests between some simple software free eye tracking to understand, through the data, which is more efficient.
I have the task of creating a graphical interface or a simple path that the participant will have to follow with the eyes, collecting data in specific locations on the screen, so finding the most accurate software and presenting a report at the end of experiment.
The software that I have not found it possible to have a log file containing all of the gaze coordinates in real-time participant but the Ogama program might be my solution!
you know help me? there is a guide?
sorry for my english, I'm an Italian student
Thanks again

Dear Sir or Madam,
I had a measure by Eye-Tribe ET100 and OGAMA. I evaluate the results and I have problem with correct setting in OGAMA sw in window Experiement Settings window.
I set the sampling rate for gaze to 60 Hz. The size of moniotr was 1600x900. I am not sure in setting other values. They are Fixation calculation parameters - Maximum distance... and Minimum number.... If I change the maximum distance from 20 to 40 (50) and recalculate fixation, the number of fixation rapidly incerases. What numer for maximum distance is correct in my case of size of mentioned monitor? The "Minimum number for of samples" I set to 5. I suppose it is correct.
Thak you for answer.

New Post: Eyetribe Calibration

First of all thank you for the software. I'm currently running a study using the Eyetribe eye tracker. I was wondering if it was possible to automate the calibration process. What would be ideal is for the participants to sit down at the monitor and once they start, the calibration begins. If the calibration achieves a score of 4 stars or more, the test itself begins. If the calibration doesn't reach this level then it begins again.

Mostly I don't want to have to have to stay by each participant to ensure that the calibration was completed properly and I don't want the participants to need to click on anything to begin the experiment. The more automated the process can be the less likely that outside variables will be introduced.
