Handling connected devices

[mshukun]

I created an application that requires both the Microsoft Xbox controller and Oculus Rift HMD connections. The Vizard throws error messages in Vizard IDE when these devices are not connected. I would like notify device connection errors to the user using vizinput.message(). Unfortunately, I haven't been able to find the way to do it. I appreciate if you have any suggestions/solutions regarding the problem.


Pseudocode:
IF Both Oculus Rift HMD and Xbox controller are connected
THEN start the application
ELSE
THEN show message and Exit the application


Thank you,
