What's cooking at the Consumer Electronics Show? AI meal planning, a robot to chop your onions and vegan pork. Food and tech have come together at the annual lifestyle and gadget extravaganza, with blockchain, artificial intelligence, voice recognition and computer vision technologies keeping things fresh. Here are a few of the innovations on display in Las Vegas this week: Many a family is flummoxed by getting meals on the table every night of a busy week. AI may be able to help with that. Its use in meal planning and preparations was a hot topic at CES. GE Appliances, a division of China's Haier, unveiled its smart hub integrated into a microwave which uses AI to analyze food in a consumer's refrigerator and make recipe suggestions. "You can see all the food you have and get a recommendation (for recipes), to cut down on waste," said GE's Jeremy Miller. If the unit is paired with a compatible cooktop and oven, the system will also keep track of the cooking process to help ensure adequate, personalized cooking. GE also announced a new kitchen concept dubbed Shift, which will use face and voice recognition technology to personalize its design in real-time to accommodate family members of different heights, ages or cooking abilities.
