Dear Martin,

I just executed and it is working fine - Thanks.
I need to use my page instead of existing page for scrolling. Also I need the sample for eye click event sample program.

Could you please guide me for above.

Chithirai,

Check the our GitHub open source archive. Scrolling in C# is done in this sample.

Click event you will have to decide upon yourself. It's very easy to get the X/Y screen coordinates using the API. The C# client is available with corresponding docs. Of course also API Clients for Java, C++, ObjectiveC and Unity (C#).

Click after 1 second dwell on button?

Have fun!

Hi Friends,

My name Chithirai, I am happy to join in The Eye Tribe Dev forum. I just purchased Eye Tribe Tracker and would like to get sample code/solution for click event and scroll event. I need it to apply one of my demo just to click ppt.

Thank you in advance.

Chithirai

You should insepct the TET Open API, the C# SDK Documentation or C# SDK Source Code if in doubt about a value.

Thank you very much, Anders.

One more question, what is the frequency of the sample rate? I saw the sample time in the EYETRIBE UI. Is the unit of sample time milliseconds?

Your problems seem to originate from general C# programming issues. The TET C# SDK is a library project. It cannot be 'run' but is designed to be referenced by C# projects and enables developers to quickly write programs that use our technology.

Looking at your code I strongly advise you to use the C# SDK instead of writing your own network layer. If you clone the C# samples and open that solution in VS you will see how usage of the C# SDK is intended in a WPF C# project. You should inspect the code examples to learn how to use the SDK library. If you use the example code setup as a basis for the project you are doing then you will save a lot of time.

Also, several users of this forum have shared their code. Maybe inspecting those projects could be an inspiration to you?

Best of luck!

Hi Anders,

Thanks for your reply. Unfortunately, it doesn't help.

I downloaded the examples several days ago. There are calibration, scroll and mouse control examples. But what I need is only the gaze data.

I created a new project in visual studio, included the SDK in references. I copied the "getting data" example on the website into a main( ) program. However, I still got an error that "} expected" at the first "{" in the main() program, though I did close the main().

Actually, I read every topic in the forum. Most of the topics are the same question as mine. But they were always answered with a link to your examples or a simple sentence. I do believe if you could please give more details about how to get the gaze data, it will help a lot of beginners like me. Thank you very much in advance.

Regards,
Chandler

run the example on the website

2015-05-02T18:58:27+02:00

Hello,

I have problem running the example "getting data" on the website (http://dev.theeyetribe.com/csharp/).

I add the example into the C# SDK in visual studio. The original property of the SDK is class library, and I got the error of "A project with an output type of class library cannot be started directly". if I change the property to console application, then I got the error of "does not contain a static 'Main' method suitable for an entry point".

Can anybody help me with this issue? I want to run the example of "getting data" on the website and get the coordinates of the gaze point. But I am really new to C#. Any help is much appreciated. Many Thanks.

Chandler
