The Fujitsu New Generation GPS Cane is a prototype walking stick with a lighted display built into the handle. It can give directions or show the user's heart rate with the aim of helping seniors get around. Fujitsu packed the cane with GPS, Bluetooth, and Wi-Fi. A route can be programmed into it, and it then takes over with helping to get the walker to the right place.
