  1. Team Members: Kelly Han Kyle Mauer (Team Lead) Kevin Vo Advisors: Dr. Aziz Inan (Faculty) SrijaPidaparthy (Industry) Dr. Deborah Munro (Client) Dr. Andrew Nuxoll (Instructor) The posture pedometer cummerbund October 2012 Program Review

  2. What does the Cummerbund do? • Will indicate if user has bad back posture. • Will display the user’s step count.

  3. BUT HOW, KEVIN? • The design utilizes two inputs, two outputs, and a “brain”. Vibration Motors Flex Sensor Arduino Uno Pedometer Switch Arduino LCD

  4. Deadlines and Progress • Major Milestone • Finish Functional Specification v1.0 • Deadline: Oct. 5 • Completed: Oct. 4 • Progress • Met with SrijaPidaparthy (Oct. 2) • Received Arduino Uno from Dr. Hoffbeck (Oct. 7) • Ordered Parts (Oct. 14) • Researched LilypadArduino Components • Pedometer Predicament

  5. What’s a Lilypad? • LilypadArduino is a line of components made specifically for interfacing electronics with fabric.

  6. Pedometer Predicament • We encountered issues with interfacing a ball and mercury tilt switch for the pedometer function. • Ball switch needed 30° tilt to register a contact. • Mercury switch needed 5° tilt to register a contact.

  7. Our Solution… • Our first idea was to replace the tilt switch with an Arduino GPS Shield that would record the distance the user walked. • Problems • Problems: The GPS would not be able to determine if the user is walking or driving. • Shield is too bulky.

  8. Final Decision • Our team decided to utilize a pedometer spring switch contact. • This mechanism is powered by a 1.5v coin battery • Output is ~1.5 volts when contact is open • Output is 0 volts when contact is closed

  9. Future Milestones • (Minor) Finish first draft of Design Document • Deadline: Nov. 2 • Estimated finish date: Nov. 1 • (Minor) Finish Design document v.95 • Deadline: Nov. 9 • Estimated finish date: Nov. 8 • (Major) Interface Flex Sensor • Deadline: Nov. 14 • Estimated finish date: Nov. 14

  10. Future Milestones cont. • (Major) Complete Design Document • Deadline: Nov. 16 • Estimated finish date: Nov. 15 • (Minor) Final Budget Calculated • Deadline: Nov. 16 • Estimated finish date: Nov. 15 • (Major) Implement Pedometer with Arduino • Deadline: Nov. 30 • Estimated finish date: Nov. 30

  11. Team Concerns • Make sure the flex sensor contours with the back. • We want to make sure that the sensor detects a change in back posture effectively. • Interfacing inputs and outputs with Arduino • We still have not had much experience with Arduino hardware and software

  12. Plans for Progress • To make sure we complete our milestones we will start early on documents, testing, and continue to research Arduino hardware and software. • Our Plan • Interface Flex Sensor with Arduino • Interface Pedometer with Arduino • Determine Cummerbund Fabric
