Integrated Workout Shoe Peter Katlic Major: Computer Engineering Minor: Japanese Advisor: Shane Cotter

Goals Produce a device that meets the following criteria: Able to be attached to the shoe laces for testing and integrated into a shoe for the final design Have a total cost in between step counters and expensive solutions ($30-$50) Record time, pace, distance Measure distance within 10% error

Current Offerings – Step Counter Uses internal switch to count “steps” Simple design Small size Low cost($10-$20) Accuracy(up to 50% error rate) Single user

Current Offerings - GPS Garmin Forerunner Uses GPS signals to record waypoints  distance Accuracy(1-5% error rate) Ease of use Multiple users Cost($120-$330) Loss of signal under tree cover Bulky design

Current Offerings - Accelerometer Apple Nike + iPod Uses accelerometer to measure acceleration  distance Accuracy(up to 10% error rate) Ease of use Multiple users Cost($30) (factoring in iPod($150-$350)) Reliance on iPod

Components Microcontroller Accelerometer Enclosure LCD display Battery

Implementation Take acceleration measurements Average measurements Calculate velocity, distance Store data
