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
