Hi. I am trying the example in tobii tutorial but cannot make it work. It is showing me error [The behaviors dose not exist in namespace “clr-namespace:Tobii.EyeX.Wpf;assembly=Tobii.EyeX.Net”].

Hi @dawood154, can you kindly be more specific in terms of which example script you are running.. I assume the samples supplied as is (without modification) are running as intended? Thank you for the greater detail.

Please go to the following link: https://tobii.github.io/CoreSDK/articles/wpf.html . I am trying example under example under GazeAware behaviour. I am trying example as given but still cannot run the code and it shows the error I mentioned above.

Hi @dawood154, apologies, but there is a mistake in this sample code whereby the command

using Tobii.EyeX;

should now be replaced with

using Tobii.Interaction;

The code should run as expected from here, but let us know if you hit any further problems.

Unfortunately this dose not solve the problem as I was already using Tobii.Interaction. I am still getting the same error and unable to run the code.

using Tobii.Interaction;
using Tobii.Interaction.Wpf;

I am using these two libraries. I tried to put others but it shows me that they are unused. I found another code in example under “Getting Started with WPF Application” in following link : https://tobii.github.io/CoreSDK/articles/getting_started.html. which is using

using Tobii.EyeX.Wpf;

I tried this also but it show me error. Please let me know what should I do now.

Hi @dawood154 sorry for the delay in reply during the holiday period.

I think it might be worthwhile for you to try running the pre-written WPF samples available online @

https://github.com/Tobii/CoreSDK/tree/master/samples/Wpf/Interaction_Wpf_101

The User Presence is a useful place to start and let’s see if you get the same errors. thanks.

Hello I am looking for some sample code in WPF based on “look and click” without any keyboard interaction in Tobii Core SDK. Thank you

[Grant [Tobii]]

Hi @devi, the additional API samples for the Tobii Core SDK you can download @ https://github.com/Tobii/interaction-samples
which should hopefully point you in the right direction.

There’s still an error in the WPF example (https://developer.tobii.com/consumer-eye-trackers/core-sdk/getting-started/)

The line
xmlns:tobii=”clr-namespace:Tobii.EyeX.Wpf;assembly=Tobii.EyeX.Net”
should be
xmlns:tobii=”clr-namespace:Tobii.Interaction.Wpf;assembly=Tobii.Interaction.Net”
