Smarter water bottle.
Duo is a smart water bottle that provides an easy way to track daily water intake goals without oversaturating the user with granular information. It utilizes a simple interface to create a sense of shared achievement between two users – propelling each into healthier habits.
3D Printed mockups helped to determine the final form. I tested LED behavior using an Arduino and created a functioning works-like prototype.
Users can pair with a friend by "cheers-ing." Paired users can compete towards a daily intake goal and see each other's progress. The input button doubles as a coin-open battery door, revealing the two CR2032 coin cell batteries that power the bottle.
