Problem Statement The objective of this project is to develop a non-athletic track-oriented pedometer that would sell commercially for no more than $100. Its features include: A distance calculation based upon global position satellite (GPS) data. Elapsed time measurement. Average speed in miles per hour.

Design Objectives Design Functionality Design Constraints -Provide fairly inexpensive, accurate and interactive pedometer for people who exercise outdoors. Design Constraints -Software cost will be less than $100 -Weigh less than 1.5 lbs -Compact dimensions Intended Users / Uses -Runners, cyclists, rollerbladers, canoers -Display elapsed time, distance traveled, average speed, and total calories burned

End Product Description The GPS Pedometer is a combination of a GPS receiver connected to a Palm PDA, via a data cable. The Palm PDA contains software that is implemented using Java to interact with the user. The developed software will retail for less than $100.                                               

Assumptions and Limitations The user already owns a PDA and GPS Receiver The software is limited to serial port based Palm PDA’s Weather will not affect the unit The GPS Pedometer will not be dropped from a great height The software for the GPS Pedometer will retail for less than $100 The unit must be lightweight GPS resolution is at best 6.1 feet

Technical Approach Hardware Software - GPS receiver - Palm m105 PDA - Serial port connections Software - Java interpreter on Palm OS - Interactive software prompts user for weight, age, sex, and activity
