Blink Up and Drink Up

Smart Water Bottle will remind you to drink water after certain amounts of time. Drinking water is one of the most important elements to maintain a healthier lifestyle. If the smart water bottle is lighting up, it is time to drink up your water!


Ideation

I care about health and healthy interaction with the object and human. This is the mind map of how I came up with the smart water bottle -the way to make a healthier interaction between human and water bottle.

For Whom?

Smart Water Bottle is for people who forget to drink water regularly or need to drink every certain time. This is for the women who are expecting or breast-feeding need additional fluids to stay hydrated. From my research, the Institute of Medicine recommends that women who breast-feed consume about 13 cups of fluids a day.


How does it work?

The smart water bottle will count time to give a reminder to drink water to the users. Every time when the user lifts up the water bottle and puts it down on the desk, the smart water bottle counts certain time and then light up.

User Flow

The user flow is simple. Once the user holds the water bottle to drink water, the sensor detects the pressure and then counts the set-up time. As the set-up time arrives, the bottle lights up as a reminder of drinking some water.

Demo

I set the timer after about one minute. So, the water bottle lights up after one minute at the end of the video.

Key Codes

I had to figure out what sequence would be followed by different conditional sentences. At first, I tried to use a delay function to make the lighting reaction happen late, but it has a problem of detecting input. For the final, I used the millis function to make the if statement possible for delaying the output.

Sketches

I considered where the sensors should go to detect the input and where the output should be positioned. From user testing, I realized that people tend to put their thumb on the little hole, so I put the force sensor on that hole. The led strip should be on the bottom of the bottle so that it doesn’t distract people from drinking water.
