The classic walking cane has been recently revamped by Fujitsu. The new smart cane from the company adds sophisticated technology to the traditional cane by including Bluetooth, GPS, WiFi and a cellular radio. The front of the cane features multi-color LED lights that light up to show directions using the GPS. Green arrows show the direction to walk in and red flashes alert users to upcoming turns. Additional sensors on the device can monitor temperature, humidity and heart rate and can notify loved ones of abnormal vital signs. Loves ones can then remotely send directions to a hospital or safe resting location.
