Most of us have heard from health experts that we’re supposed to consume at least eight 8-ounce glasses of water a day, but how can we know if we’re hitting this target? Smart Intern and Lab collaborator Simone Capano set out to explore a solution to this problem with Hydramate, a simple system that passively reminds us when it’s time to drink more water.

The project explores the notion of time and how it can be represented in an ambient way through a 3-dimensional interface. “I’ve always been very interested in finding a way to manage time in a physical way. Time is for sure an abstract element, and nowadays a lot of applications allow us to manage time effectively, but what if time were controlled through a tangible object, acting as a reminder, speaking to the user with a specific language/behavior?” asks Simone.

Hydramate is an electronic coaster that measures a one hour cycle, divided in four quarters, each representing 15 minutes. As time passes, each quarter begins to gently glow giving the user a visual cue of how many times they have raised their glass to drink. Once a whole hour has passed since the last sip, the device begins to blink signaling that it is time to get hydrated. The blinking becomes stronger while the user is drinking, and once they set the glass back down it resets to the gentile glow of the first quarter .

Simone created a fully functioning prototype with an Arduino micro controller. The shell  is  made of spray-painted polycarbonate, and the technology inside of it is very simple:

- A Photocell senses when a glass has been placed on it

- An Arduino Pro Mini  powered by a 3.3V Lithium batter receives the input from the photocell and controls the LEDs accordingly

We look forward to hearing about how this project has developed since the prototype was constructed, and how well test users feel the device helps them to manage their hydration.

    While I’m intrigued by the interaction design here, please let’s remember that the 8 glasses of water a day recommendation itself appears to have been mistaken. See for example http://www.scientificamerican.com/article/eight-glasses-water-per-day/
