Target Sport: runningTarget 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.

Functional Requirements: Record and reconstruct the accelerometer data into

an animationThe 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.

RequirementsRequirements

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.

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
