Mistake in the javafx-sample code

Hello,

I am trying to use the sample calibration in "javafx-sample" and I found a bug. The ImageView "gazeIndicator" is not placed in the preview well. The gaze point does not correspondent with the center of the circle-image. I think the method "getGazeIndicatorAnchor" in SceneController should be written in a different way.

JavaFX example as a Netbeans project

I've tried to open the gradle project on Netbeans but it doesn't work at all.
Can you make available a Netbeans project instead?

thank you.

ControlsFX Update

The build is not working with the more current versions of Java.

The line ControlsFX Error: ControlsFX 8.40.10 requires at least Java Version 8 Update 40 convinced me it was a version issue. I have Java 8 Update 111 currently installed. Updating ControlsFX to 8.40.12 in javafx-sample/build.gradle resolved the problem on my machine.

Published JavaDoc is outdated

The JavaDoc at http://eyetribe.github.io/tet-java-client/ that is linked from README.md shows version 0.9.60, not the current version 0.9.77.

virtualbox

Hi,

I'm using an VirtualBox machine running Windows 10 to use Eyetribe Server/UI on Ubuntu 16.04 host. All USB devices are readable except the EyeTribe. Any add-on or protection to fix/disable ? Should I open ticket on VirtualBox support ?

Regards,

Kannar.

Constants about eye-tracking state not correct in class GazeData

I found that two of the fives constants of the class GazeData do not correspond the constants values of the class. Maybe the field gd is not correctly updated

gd = 7 in gaze state while STATE_TRACKING_GAZE = 1
gd = 6 in eyes state while STATE_TRACKING_EYES = 2

The GazeData object is retrieved via the onGazeUpdate implemented method of the interface IGazeListener.

Sincerely,

Francis

Netbeans Maven Repositories

It seems that the only reason why I am not able to use bintray (eyetribe) is because you are not publishing an index at bintray (if I got it right...).
It is really annoying not to be able to connect to jcenter or bintray jfrog with Netbeans.
Any help you can provide me?

Thank you.

sdk for linux?

Hi,

Does your jar and sdk api works on linux ?

Possible issues when calibration change

Hi,

When you calibrate with the "EyeTribe UI" outside a Java application, the listener method onCalibrationChanged() is only called after the first calibration, not after the next ones.

Moreover, the calibration average error in degrees seems not to be updated (it equals 0.0) when you use either:

the parameter CalibrationResult.averageErrorDegree of the onCalibrationChanged() listener method
the attribute GazeData.getLastCalibrationResult().averageErrorDegree

But, if you desactivate and then reactivate the server, the attribute GazeData.getLastCalibrationResult().averageErrorDegree is updated.

Sincerely,

Francis

GazeManagerCore.ApiVersion is not visible

GazeManagerCore offers many publicly accessible methods that overload activate() and take an ApiVersion parameter, as in the example in http://dev.theeyetribe.com/java/:

public static void main(String[] args)
{
   final GazeManager gm = GazeManager.getInstance();        
   boolean success = gm.activate(ApiVersion.VERSION_1_0, ClientMode.PUSH);
}

Because GazeManagerCore is package-protected, it is not possible to access GazeManagerCore.ApiVersion from outside com.theeyetribe.clientsdk. Maybe turning ApiVersion from a nested to a top-level enum would solve this problem.

Eye tribe SDK with Unity

Hello,

I am new to eye tribe and unity both. I want to know how are the gaze points (pixels) recorded from the use of Eye tribe ? I mean in Unity (0, 0) is the bottom left corner in pixel coordinates, and the top-right corner is (Screen.width, Screen.height). So if we use Unity with Eye Tribe does it follow the same pixel coordinates ?

(Usually for our computer system (0,0) begins on the top left corner. So I am confused regarding this.)

Any help would be greatly appreciated. Thank you

Need help

I sorry, know that this is not the place but lost my dev kit for mac and there is no way to downloaded from the site of the eye tribe, can someone contact me and help me with that? thanks

Str message to JSon fails

I print the string response message but when converted to json, all x y values are 0s.
I use Windows 7, 64 bit, JDK1.7, Netbeans 7.4
Here is my EyeTribe1.java Code:

public class EyeTribe1 implements GazeApiResponseListener {

    public void onGazeApiResponse(String strResponse) {
        Gson gson = new Gson();        
        System.out.println(strResponse); // response is gaze data         
        GazeData msg = gson.fromJson(strResponse, GazeData.class); 
    }

    public static void main(String[] args) throws AWTException, InterruptedException {
        GazeApiManager gm = new GazeApiManager(new EyeTribe1());
        boolean res = gm.connect("localhost", 6555);                        
        gm.requestTracker(GazeManager.ClientMode.PUSH, GazeManager.ApiVersion.VERSION_1_0);                

        while (true) {       }
   }
}

It will be extremely useful if you add a java class with main() that uses the callback function, and do something simple, like print to screen but after the GazeData object is formed.

Thank you,
Kris

onGazeUpdate not working with new SDK

Hello,

I am trying to use the new SDK (v.0.9.60) and the code from your websites gives mi no output - I can not get the gaze data from the eye tribe.

package com.theeyetribe.javafx;

import com.theeyetribe.clientsdk.GazeManager;
import com.theeyetribe.clientsdk.IGazeListener;
import com.theeyetribe.clientsdk.data.GazeData;

public class TETSimple {
    public static void main(String[] args) {
        final GazeManager gm = GazeManager.getInstance();
        boolean success = gm.activate();
        final GazeListener gazeListener = new GazeListener();
        gm.addGazeListener(gazeListener);
        Runtime.getRuntime().addShutdownHook(new Thread() {
            @Override
            public void run() {
                gm.removeGazeListener(gazeListener);
                gm.deactivate();
            }
        });
    }

    private static class GazeListener implements IGazeListener {
        @Override
        public void onGazeUpdate(GazeData gazeData) {
            System.out.println(gazeData.toString());
        }
    }
}
