San Francisco, United States | Microsoft is putting its machine brains into a Liebherr refrigerator.

The US technology giant and Liebherr are collaborating on a new "SmartDeviceBox" that take the kitchen appliance beyond cooling comestibles to reminding people what they need at the market, Microsoft principal data scientist TJ Hazen said in a blog post

The box is an internet-connected module that fits inside refrigerators and freezers.

Microsoft is putting machine vision capabilities to work to enable boxes to recognize milk cartons, ketchup bottles and other food inside refrigerators, according to Hazen.

The SmartDeviceBox uses cameras and object recognition technology to track what is in a refrigerator, keeping an inventory list, so that can be accessed through applications tailored for smartphones powered by Android, Apple or Windows software, Microsoft news center staff member Athima Chansanchai said in an online post.

"In the near future, Liebherr refrigerators will help you shop and plan meals through intelligent food management," Chansanchai said.
