Team2 9/2/09 Target Sport: running Target Users: coaches and athletes Concept: ◦ Put accelerometers on athlete's body ◦ Reconstruct motions based on recording data ◦ Can be used in various applications Motivation: ◦ Runners cannot see how they run unless someone videotapes it; this is difficult while moving. ◦ Being able to see a 3-D model of their running style will allow them to improve.

Competitive Analysis 9/2/09 - Aware XC2 Athletic Form Monitor System ◦ Product page:  (spec: ◦ Price: $5000 ◦ Sport: general athletics training ◦ Contains several accelerometers and some other biometric sensors

Requirements 9/2/09 Functional Requirements: Record and reconstruct the accelerometer data into an animation The animation should be accurate up to 85% of the actual motions of the athletes. Timing Requirements: The system will record in real-time and take no more than 3 minutes to finish reconstruction. Reliability: The parts attached to the runner should tolerate normal running wear and tear. The battery should last at least 3 hours.

Requirements 9/2/09 Portability: The parts that connect to the athletes should be able to operate in a variety of conditions without hindering the athlete. Safety: The system should not harm the athlete in any way.

Technical Specification 9/2/09 Hardware ◦ Accelerometers ◦ Minimal processors to record accelerometer data, such as the PIC18 ◦ Flash drives for storage of data ◦ A way to attach hardware to the user, such as a bodysuit or Velcro straps Software ◦ The program will use inverse kinematics to reconstruct the data into a 3-D model
