Changing the number of calibration points will affect the quality (and thereby success rate) of your calibration process.

If you want to modify the calibration process you need to look at the methods that create the calibration points, change those to generate the desired number of points in the desired positions and then start the calibration process with that number.

Also, you should make sure to use the latest version of EyeTribe Unity DevKit as this contains more comments than the early samples.

Unity • Calibration

2016-05-26T08:47:53+02:00

Hello,
I would like to know if it's possible to reduce the number of calibration points in the calibration scene. I use the calibration script of Aircraft. I've tried to put a 6 instead of a 9 in

Code:: GazeManager.Instance.CalibrationStart(9, this);

and delete 3 lines _CalibrationPoints.add in order to only have 6 but it does not work, the calibration didn't want to launch. I don't mind if there's 6 or 9 points, all I want is to have the possibility of having all my points on the left side or on the right one. I've also tried to put twice the same line and to delete an another one but this time it's launch the calibration but I've got few calibrations points and after nothing..

Is there someone who have an idea of how I can do that ?

Thanks

Unity • Re: Lowering calibration time

2016-04-29T23:22:45+02:00

So the number in the Invoke(...) calls changes the delay between points?

I have already talked with others at your company about this use case for approval.

Unity • Re: Lowering calibration time

2016-04-29T14:50:55+02:00

You should have a look at the calibration script and change the timings of the Invoke(...) calls to fit your needs. Bear in mind that doing so will affect the successrate of the calibration process.

Also, please remember that doing commercial software with the EyeTribe Dev Kit is in breach of the license agreement that comes with the kit.

Without knowledge of you implementation, it is impossible to answer your question. Please supply information about the following:

Have you implemented your own calibration script?

Are you using a calibration script from one of the open source examples?

Have you looked through the code of the calibration script?

2016-04-15T21:27:28+02:00

What options do I have for lowering the calibration time? I'm making a game for an exhibit that has a high volume of users. I would like to cut back on waiting time in line.

Unity • Re: Store Data

2016-04-11T14:13:27+02:00

Should be possible with the builtin .Net StreamWriter class.

Something along the lines of:

Code:: string saveFilePath = "gazedata.txt"; StreamWriter logWriter; public void OnGazeUpdate(GazeData gazeData) { if(logWriter == null) { logWriter = new StreamWriter(File.Open(saveFilePath, FileMode.Create, FileAccess.Write, FileShare.Read)); } logWriter.WriteLine(gazeData.SmoothedCoordinates.X + ":" + gazeData.SmoothedCoordinates.Y); logWriter.Flush(); } public void StopAndSave() { if(logWriter != null) { logWriter.Flush(); logWriter.Close(); } }

Unity • Store Data

2016-04-11T13:25:49+02:00

Hello, I would like to use the EyeTribe in Unity and I was wondering if it's possible to store the data of the the gaze in file. For example in the game aircraft I would like to know if it's possible to store the data of the gaze position in a tsv, txt or csv format. And if it's possible how can I do this ?

Thanks

Unity • Re: Unhandled Exception: System.Reflection.ReflectionTypeLoa

2016-04-06T09:47:23+02:00

To elaborate, the Newtonsoft.Json uses reflection which is not part of the .Net 2.0 subset default setting in Unity. Hence the change is needed.

Unity • Re: Unhandled Exception: System.Reflection.ReflectionTypeLoa

2016-04-05T22:00:43+02:00

Thank you for your response. I had already updated that setting. There are known issues with Newtonsoft.Json in Unity I guess.

This issue kind of mysteriously went away just like it came.

I believe this was answered in this thread.

This will be better documented in the next EyeTribe C# SDK release.

I recommend using the unity example as basis for your project.
