Students at Canada’s Simon Fraser University have come up with an idea to remind you if you forgot your cell phone, keys, or other important items before you leave your home or office. Utilizing RFID technology, they have created the Ladybag. The handbag reacts by showing what is missing on its LED display. Taking it one step further, the bag reflects emotions via sensors. Grab its sides and it shows a happy face. Play with the zipper and it shows nervousness. While we are not sure that we like the second attribute, we can’t wait until this prototype is picked up by an enterprising backer.
