There is a Quora topic dedicated to frequently asked questions about JARVIS.  In terms of the 3D part (as opposed to the voice recognition part), see my recent Quora answer about Magic Leap (company):

• What are the possible applications of Magic Leap’s augmented reality technology that adds CGI 3D objects into the real world?

• How do I make my own JARVIS?
• How do I build Jarvis (at least a prototype)?
• How do I make a simple robotic servant?
