this behavior is expected because the WikitudeWorldBrowser does not change the interface orientation into landscape in the cam view. There is currently no workaround to change this specific behavior.

I have developed an app using the Architect Engine and I run it in Wikitude Browser on my iPhone 5. My problem is when I ask the user for input in the landscape mode, the keyboard orientation doesnt change with it and remains in the potrait mode. I tried using the sample twitter app and facebook app and found the same issues. Can you point out what the problem is and whats the work around for the problem?
