Vuforia Driver for Custom Devices

Hi,

I am trying to use Vuforia Engine with an Android eyewear device which is not supported officially by Vuforia. Therefore, I am thinking creating by own Vuforia Driver. I read documents in Vuforia and examine Driver Sample. However I am not sure I understand steps to create a drive. I am asking that:

- How should implement a Driver using Driver.h file? Should I rewrite functions in RefDriverImpl.cpp? Or should I create a single cpp file and convert it to .so file?

- After creating driver how can I give to Vuforia Engine?

- How can I test this driver in Unity?

(I am new to C++ so my questions may be weird)

Thanks in advance.
