It's 8:00 a.m. and you are running out of the door. You walk outside and your handbag suddenly says, "Wait! You forgot your keys!" A talking handbag? Yes, it's true. This "smart bag" can "talk" to the things you often bring with. If you forget your keys or drop your purse, for example, the bag will tell you. How does it work? There is a "smart chip" in the bag. You put other chips on your phone, purse or keys. Then the bag and the others can "talk" to each other--and you! SMART CLOTHES These clothes change colors--while you are wearing them! Is it hot outside? Watch your jacket change from dark blue to a lighter color to protect you from the sun. Did you spill coffee on your white trousers or shirt? No problem. These smart clothes never get dirty! Who needs the "smart clothes" most?
Someone working in a library. Someone who has a bad memory. Someone working in a restaurant. Someone who always loses his or her mobile phone.
