In order to help the visually handicapped people better find their ways independently, a team of researchers from the National University of Singapore have collaborated an electronic cane that lets its users explore through unfamiliar ways with no difficulty.
Based on geographical apps like Foursquare, the users can find their way ahead with no barriers, because the information of hurdles ahead would be sent to the visually handicapped via a Bluetooth earpiece to help them distract from the way to escape from the obstacles. Almost at the same time, the wheels of the cane will change their direction automatically too, to keep the visually handicapped away from possible obstacles. On the other hand, the Blindspot can connect its users to their friends as well, via the combination of ultrasonic sensor and tactile GPS navigator.
