Our inspiration for our project came from the Senior Vice President & Chief Information Officer, John M. Miester and his talk at the opening ceremony.
What it does
Simply take a photo of your food and get nutritional facts about it! The nutrition facts that are returned are the fats, carbohydrates, proteins, and calories. All the nutritional data is based on around a 100 gram sample so the units of fats, carbohydrates, and proteins are in grams and the units of calories are kilo calories.
How we built it
We used Android Studio to create the app interface, an api called clarifai for the camera recognition software and an api called fatsecret4 for all of our nutrition data.
Challenges we ran into
Originally we were trying to use the nutrition database api from the USDA, this proved to be extremely difficult because of the lack of documentation on the api and once we managed to extract some data, it became a massive string text wall. So we switched to fatsecret4 which had much better documentation and easily integrated into Android Studio.
Clarifai though ended up being successful was also difficult given its lack of documentation from being updated one day before our project started.
Our lack of experience with Android Studio also slowed progress.
In general finding good open source api's with good documentation was difficult.
Accomplishments that we're proud of
We are proud of this entire project, after attempting to deal with bad api and learning new programs for the majority of the project, our vision of our project seemed to fade, but with persistence we achieved our original vision.
What we learned
What's next for Macrofinder
If we were to continue developing this app we would start by reformatting the interface and making it look nicer.
Then we would filter the results of the picture to prevent non food options that crash the app.
Finally we would have a scaling feature that would more accurately give the nutrition facts based of the portion size by placing a certain object next to the food.
