Immersion is the key, no matter who you are.
As an adult who has spent the last ten years surrounded by all of the new technology as it becomes available, being filled with wonder as you step into a virtual world is an incredible feeling. It's the kind of thing that makes you want to host regular parties to introduce as many friends as possible to this new tech, and I have. Over and over again I find myself amazing at how similar the reactions I see on every new users face matches my own, and it's so damn cool to watch I'm usually planning the next get-together in my head as the current one is happening.
Kids are a little different, thought. The experiences of a child rarely line up with the experiences of an adult, due to their perception and the sheer volume of differences when considering things like life experiences. To really get a feel for how kids experience VR, you have to talk to them and get a feel for what they want out of a virtual experience. So we did.
My oldest daughter has been fortunate enough to spend more time in VR than most people in the world today, which allows for a unique perspective on several levels. Her opinions are no less valid than anyone else's, but it's fascinating to hear how similar her thoughts are in this situation to most adults I've encountered. The ability to move, the ability to reach out and interact, and the ability to look down and see your hands are a huge part of what makes the HTC Vive stand out as something special for now.
