Childhood Obesity fought using Computers?

It seems like the UK has caught on to the Dance Dance Revolution video game where players dance on a sensored floor based on dance move instructions that pop up on the screen.

Apparently health and fitness workers in the UK have adapted something similar using a computer and a dance mat. I hope they don't get sued for patent infringement! Apparently this is being done in Luton, Beds.

I think it's a great idea making physical activity fun. I wish more kids would get involved in activities like this.
