This project is motivated by the growing trend in super high heels. Improper posture in high heels can lead to knee stress and injury. The core pieces of Cinderella are force sensors that are placed inside of high heels: one at the heel and one at the ball of the foot. Correct posture and movement in high heels would show that the foot is making first impact at the ball of the foot, and the second impact point would be at the heel of foot. When the user is stepping incorrectly in the shoes, a processing sketch will trigger an audio reminder to straighten up. When the user is stepping correctly, there is the creative reward of a motion generated artwork being produced by the same processing sketch. This sketch can be saved as a .jpeg file that can be uploaded on a website, or printed out.
