People unconsciously have bad postures such as crossing their legs, tilting their body left or right, hunching their backs or hanging their bottoms on the seat while they are sitting on chairs. Those bad postures are bad habits which destroy balancing of people’s body system, and could cause lots of problems on people’s spines gradually. We wanted to develop a device that assist people sit right.

Background
Sitting right is all about the position of one's pelvis. A pelvis should be in a right position to balance our spine. It can be achieved by sitting straight up, but not touching your back to the chair, and not crossing your legs.

Audience
People who are working at a desk.

User Scenario
While a person is sitting on the Dr. Posture, it detects balance of one’s weight on it. Once it detects unbalancing, there is a physical avatar collapsing instantly which helps one paying attention on one's posture. There would be also a Processing application on the screen that if the person doesn't correct one's position for a certain period of time, a monster reaches to a virtual figure and burns the figure.

Implementation
Dr. Posture is a sitting mat that is made of 6 wooden plates with four FlexiForce 100 lb sensors inside and covered with a fabric. Two sensors on the front detecting a position of one's legs, and two sensors on the back of the mat are sensing balancing of one's body.
Physical avatar is made of wood with two servo motors attached at the bottom. According to values of sensors, the physical figure is instantly collapsing its body or/and moving its legs. Processing sketch on the screen reacts also instantly, but it gradually shows its reaction based on times one's posture.

Conclusion
Simple technology can interact with people well.
