P10010: Motion Tracking Sensor


Project Summary Project Information

The Nazareth College Physical Therapy Clinic has expressed the need for a portable motion tracking system capable of measuring patients' range of motion in their natural environments. The primary ranges of motion of interest in this project are:

  • the motion of a human limb, where a limb is defined as a 3-bar linkage, for example: upper leg, lower leg, and foot.
  • the motion of a human's lower back, where lower back is defined as the lumbar region, with 3 points of contact: sacrum, L1-L2, L3-L5.

This project is focused on researching the sensor aspects of a motion tracking system comprising of multiple sensors, a portable microcontroller, and some form of software interface. A sensor enclosure will also be investigated to be compatible with the human interface designed in P10011.

The goal of this project is to create a portfolio of multiple sensor options for future RIT senior design teams working with Nazareth.
