I've been invited to give feedback to all Parsons students, regarding your thesis projects.
You are addressing a very serious problem in America today: childhood obesity. So many schools have had their budgets cut for physical education, so there needs to be more interactive and fun tools to enable movement for kids. Yours is a step in the right direction.
You would do well, however, to articulate more clearly how your system works. I see no indication of it in your blog write-up. You simply state the problem (lack of physical activity among kids) and propose a solution (encourage physical activity among kids). We need more systemic thinking on your part to show how this fits into curriculum at elementary school. Who makes it? What does it actually do? What games do kids get to play with it? How is it different from Nintendo's Wii, for example?
Great start. But more details, please! J.
