I enjoyed seeing the kids interacting with the elderly in an inter-generational environment such as the playground. Perhaps, this field of obstacles could very well be implemented in such an environment.
Looking at this field of obstacles, it would be nice if there were a set of rules that went with every single obstacle. These set of rules could very well make the game a lot more enjoyable for adults and children. And perhaps children and adults could pair up?
There are a lot of possibilities. It's a good cheap alternative to the high tech tools such as virtual reality headsets.
