How to fill out a JotForm in VR mode?

Dear Sir/Mdm, i would like to create & integrate (embed) a JotForm into my VR (Google Cardboard) experience. However, would like to seek your advice on how best for user to input the Typeform whilst in VR mode - short of removing the phone from the headset and typing (breaks the VR experience). Is there a 'hack' to enable a more seamless experience? e.g. voice response? virtual keyboard typing etc?

Thanks much.

As far as I can see, Google Cardboard will work only with certain apps, I'm not sure how it behaves while filling out web forms, if the keyboard is opened or if it works with voice commands. However, this does not seem to be a functionality that JotForm would have to apply, for example, the apps already developed to work in VR mode have already their own way to get the input data, so it seems most likely that the app developed to work in VR should handle the user's inputs.
