Iteration 3: Speculate

Plan for Iteration 2 Minimum Viable Product (MVP): When Gaitkeeper can accurately sense a normal walking gait and provide recognizable feedback when the gait is improper. This will include an accelerometer whose reading will be processed in a program to determine walking gait and in turn vibrate the user to notify them that the gait is improper. Total Feature List (prioritized):

1. Detect walking with accelerometer High 65 hours

2. Research walking gait and angles associated at various steps High 20 hours

3. Use potentiometer and bend sensor to test ROM Medium 10 hours

4. Use switch on brace hinge to detect full extension Low 10 hours

5. Learn how to use Arduino Nano BLE function Medium 6 hours

6. Use BLE/wifi to send data to computer High 30 hours

7. Integrate walking data with computer readings to activate buzzer High 20 hours

8. Use data on computer to do data analysis for user and PT Low 25 hours

9. Test various batteries (9V, portable phone charger) Medium 5 hours

10. Test and determine best feedback mechanisms (buzzer, haptic, etc) High10 hours

11. Attach and adjust placement of sensors on brace Medium 5 hours———————————————————-——-TOTAL: 216 hours

NameFeatureHours

Mallory Add pressure sensor to brace, collect more walking data on IoT cloud, refine placement and color of wires for better aesthetics, continue working to make brace wireless, finalize PT data visual ~24 hours

Elsy Add pressure sensor to brace, collect more walking data on IoT cloud, refine placement and color of wires for better aesthetics, continue working to make brace wireless, finalize PT data visual ~24 hours

Elijah Add pressure sensor to brace, collect more walking data on IoT cloud, refine placement and color of wires for better aesthetics, continue working to make brace wireless, finalize PT data visual The desired outcome of iteration 3 is a fully functioning prototype (our MVP) where walking is properly detected. We would like the brace to have all the new components we decided upon connected and to detect the walking motion properly. This will include replacing our current components with refined ones and using our conceptual gait research in practice.
