Have a look at Asset Administration Shells (AAS) -- it is a data exchange format built on top of JSON and XML (and RDF, and OPC UA and Protobuf, etc.).
XBox doesn't work outside & in the class room. Now, I wouldn't advocate for playing computer games outside -- but this might be a nice gimmick for children's birthdays when celebrated in the garden.
A friend of mine uses these games in the classroom as a primary school teacher. Kids here all have a laptop, so when they get nervous, it's a neat way for them to make a break & move a bit. Apparently, this works well for kids with hyperactive tendencies. Kinect would be too complicated in that setting as you need to purchase & maintain 20+ Kinects.
