jiahansu / gazejs Goto Github PK

I'm very Beginner....
Please help!!

I don't know how to use this.
When I use this ,arise error.「Cannot find module 'myclass'」
what should I do?please help ....

First I would like to thank you for this package. It is really helpful to be able to integrate my EyeX with my js project.

I am wondering how I should calibrate the eye tracker. Should I do this from the Tobii software before running my js project, or is there a way to access the calibration procedure from within gazejs. I notice that the calibration file in the Tobii folder is empty.

The following sequence of steps does not work:

• init()
• start()
• stop()
• start()

Invocation of start() after stop() throws an exception. Reason is that start() checks the status of the tracker and throws 'Illegal status to start tracker' if the status is not INIT.

I tried to modify the start() function as follows:

start: function() {
if (this.status === module.exports.INITED || this.status === module.exports.STOPPED) {
            var eventLoopErrorCode = new bridjs.NativeValue.uint32(),
                self = this;

Now I get an exception from bridjs:

                    throw new BridjsException("Buffer was allocated: " + this.
                          ^

My modification worked for bridjs 1.7.3. I only have this problem with bridjs 2.x.

Hi there,

I'm trying to get your demo app to run locally and running into some issues. It seems like the app is able to connect to the eye tracker - it's able to console.log the OnConnect and OnStart hooks just fine. But something goes wrong right after that:

Could you help me figure out what's going on here? I did some research on the Tobii developer forums, and it looks like they have deprecated their Gaze SDK - does that mean it's no longer possible to use gazejs?

Thank you!

Hi,

I tried to use your node package but it looks like the binding with bridjs need to be update for the latest version of the gaze sdk?

I used: Tobii Gaze SDK C API 4.1.0 Win64 (http://developer.tobii.com/?wpdmdl=131)
Alternatively, can you send me the link of the gaze sdk version that you have been using (4.03)?

Thanks a lot!

Hi

I'm using the package with my Tobii Eye Tracker 4C. I ran using the sample code in README.md and it worked with output as follow:

{
  left: { x: 0.35557255148887634, y: 0.5967899560928345 },
  right: { x: 0.33398452401161194, y: 0.5947821736335754 },
  prefered: { x: 0.34477853775024414, y: 0.595786064863205 },
  timeSeconds: 8.643278199015185 
}

It changes when I‘m moving fixation point on screen, so I'm sure the data is valid. The only question I'm facing is how can I convert the data to match the pixels on screen. I don't know what should I do to finish the conversion, or I should use a different API. I tried to search but find nothing useful. So is there any advise for the problem? Thx and RSVP.
