Smart appliances have a proud cheerleader in LG. They made the LCD fridge in Arrested Development's Bluth model home, and they just keep pushing toward the future, throwing ideas at the wall, waiting for any of them to catch on.
The latest development is a smart cookbook, equipped with RFID chips that can communicate "information of food" to another device—something like LG's SmartThinQ oven.
In the patent application, LG eloquently proposes that when a user tries to cook a recipe from a cookbook, he or she "may cook by guess because of insufficient information of the book." A recipe with an RFID chip could wirelessly provide some sort of useful time or temperature info to the oven, so that you don't burn your fish or undercook your bell peppers.
Of course, smart cookbooks have already been available for about three years. Apple makes one; it's called the iPad. Let's see if LG's paper version ever manages to make it to market.
