  • 27. SURVEY DATA Problems: • Uneven Heating of Food items • Oil Tadka cant be applied • Some recipes require lot of water that cannot be added in single run with microwave • Some Indian recipes require addition of oil and spices at specific duration that cannot be done with microwave alone. • It cooks the edges of the frozen food, while the inside of the food remains frozen. • Sometimes it causes sudden boiling of food items when I take it out. I’ve started wearing gloves after I burnt my hand with that. New Features Desired: • Use of metal utensils as they are already available in kitchen and cheap as compared to borosil-glass/tupperware utensils • Some provision of adding oil tadka without opening the microwave door • More presets for Indian recipes accompanied by video tutorials of Sanjeev Kapoor or Tarla Dalal or some famous cook ! • It should be Cheap! • Voice Interface, can you add that? • Automatic sensors, to detect if my food is sufficiently cooked. The microwave should automatically shut down, guaranteeing that food will not be overcooked or undercooked NiteshBhatia
