When we are busy or anxious or even excited, the common mental state that arises is that we forget the mundane things of our life. This means that when trapped in any one of these emotions you would leave your wallet or your keys or your cell phone or in any important item behind and if you are a habitual unmindful person, you will always forget something or the other. The Ladybag is a unique handbag with sensors attached to it that reminds you of the items missing from your bag and even alerts you about your emotional state.
The contents of the bag are managed through RFID technology that requires tagging important items with RFID tags. If any of your item is missing from the bag a small icon of the missing object will appear on the Ladybagâs LED screen. The emotional state of the user is displayed on the bagâs LED screen by emoticons while the user unconsciously interacts with the bag. If the user were excited or happy, she would hug the sides of the bag producing a smiling emoticon. I only hope all users would react in the same fashion under all circumstances to help the sensors attached to the bag to display the correct emoticon. Another advantage of the bag is that the RFID tags would also alert you about the stealthy acts of pickpocket.
