Bracelet + Shoes

This concept utilizes runners' shoes to hold electronic components, so the main PCB would be housed in the shoe. The shoe's sole could include piezoelectric generators to power/charge the electronics. The user would be able to control the device through a slim lightweight bracelet that communicates wirelessly with the PCB via Bluetooth. Wireless audio headphones would also use Bluetooth communication with the PCB.

Glove

The glove concept uses Samsung's flexible screen technology for display. The screen would be placed on the back of the runner's hand. A unique control system was developed for this concept:  each finger prompts an action when it makes contact with the palm. The electronic components would be housed in the glove's collar, around the wrist. As for audio, this concept also would use wireless Bluetooth headphones.

The team decided to focus on the glove prototype after consulting with the professor and Samsung design advisors. 

Showcasing the concepts and low fidelity prototypes provided a ton of feedback that was implemented into the next iteration of prototyping. This iteration's goal was to emulate the user experience that the final product would have, but due to lack of technical capabilities, only a couple of features were included.

We were able to test the playing and controlling music while running. The low fidelity prototype suggested that finger to palm contact might be triggered accidentally when the user's fist is closed during a run or exercise. The new control system, finger-to-thumb contact, prompts different commands when the thumb makes contact with fingers. This uses a simple voltage divider circuit that changes a voltage reading depending on the finger being touched. The commands then controls the music the user is listening to via Arduino and Bluetooth communication.
