Controlling moving of character using nuitrack sdk

Hello ,

I am trying to create a unity game using nuitrack sdk and intel realsense 415D, which I want to know if the user moves left or when he moves right and jump. i found another question was asking that if we can detect jump without the distance of joint to floor.
can you advise me how to start and how can I detect this actions?.

@iosif.semenyuk can you help ?
