Researchers Develop 3D Sensing Wheelchair for the Visually Impaired

Researchers from LuleƄ University of Technology in Sweden are developing a wheelchair that senses its environment in 3D and transmits this information to its user. It features a laser scanner that uses a time-of-flight technique to map its surroundings in 3D. A haptic robot, held in the left hand, translates this data to useful information for the user, enabling one to feel obstacles, essentially acting as a virtual white cane. A joystick is used with the right hand for steering.
