Our goal with this project was to create a medically trusted device that felt more like a fashionable accessory, something people would feel comfortable and confident wearing every day. Through human factors research, ergonomic testing, and iterative prototyping, we refined both form and function to strike the right balance. One key decision was to reposition the battery onto the opposite side of the strap. This allowed us to maintain a slim, low-profile main body that sits comfortably against the wrist, while still achieving an exceptionally long battery life.
