NutriRay3D uses laser light and your phone to count calories

by • January 20, 2016 • No Comments

There are may already a lot of apps which let folks estimate how many calories are in the foods they’re eating. But, many of these programs need users to either guess at their portion dimensionss, or in fact weigh the food. This is where the University of Washington’s NutriRay3D comes in. It’s a smartphone device/app combo, which uses lasers to ascertain how many calories are sitting on the plate.

Once it is fully created, NutriRay3D’s hardware component should consist of a tiny laser-scanning module which’s just plugged into an existing phone. Working with which module, users begin by projecting a grid of light points onto individual food items. Working with the phone’s camera, the app notes how those dots align with one another on the surface of every item, and of there is able-bodied to map the dimensions and shape of the food.

The app is in addition able-bodied to select what many basic foods are just based on their appearance. In cases where it can’t, yet, users can just tell it by speaking into the phone’s mic. Once the app knows what the food is and how much of it is present, it is able-bodied to consult a database of over 9,000 foods to calculate its caloric content – along with other nutritional information.

For multi-ingredient dishes such as soups, ingredient lists for talked about types are may already in the database. If users want, yet, they can manually enter the ingredients for recipes which they frequently prepare.

In lab tests of the current prototype, it estimated nutritional content of different types of foods with an accuracy rate of between 87.5 and 91 percent. Whilst which may not be ideal, it is claimed to be significantly advantageous than what’s managed by folks who just self-report via paper logs or other traditional methods.

A team of U Washington scientists and students has now launched an Indiegogo project, to raise funds for commercialization of the innovation. A pledge of US$240 can already get you a NutriRay3D module, when and if they revery production.
