Integrated Workout Shoe

Peter Katlic, a Computer Engineering student, aims to create an integrated workout shoe device that attaches to shoelaces, recording time, pace, and distance with 10% error. Comparing to step counters and GPS devices, his design targets affordability, ease of use, and multi-user functionality.

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

  2. 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

  3. 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

  4. 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

  5. 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

  6. Components • Microcontroller • Accelerometer • Enclosure • LCD display • Battery

  7. Implementation • Take acceleration measurements • Average measurements • Calculate velocity, distance • Store data
