intermittent EyeXGazeAwareElement problem

[Hanz]

Hi,

I have created a WPF form with button and web bowers element.
The button is created using UserControl.xmal as I need some styling and effect on it.The button will have EyeXGazeAwareElement whenever there a gaze.

However, there was intermittent gaze aware each time I run my program. sometime the button have gaze aware and sometime it fail. Sensor is working fine.

So can anyone advise?

Hi, Is it because the On Aware element is an inner of a Element resulting intermittent sensing?

[Eddie [Tobii]]

Hi Hanz,

I’m very sorry for the long delay in answering this issue. If I understand you correctly, you mean that sometimes when you start your application, the button is gaze-aware, and other times the button never react to gaze?

Which version of the Tobii Engine are you running?

I made a small application with the code you provided, and could unfortunately not reproduce what you describe. If you approve we could discuss your issue via email.

Kind regards,
Eddie
