Many of us use our smartphones to find our way around. Staring at your smartphone while walking is not a good idea though. Docomo’s Yubi Navi is an innovative device that serves as your “finger navigator.” It is a silicon-covered stick that leads you in the right direction when connected to your smartphone. It tells you to turn left or right by a series of vibrations and contortions. When you reach a point to make a turn, the device vibrates and nudges your thumb to the right or left. No need to keep your on your smartphone when you have something like this. We are not sure how big a market there is for a such product though.
