Sound Foresight, a British medical device manufacturer, has released its new Ultracane, a cane for the 21st century that utilizes ultrasonic waves to determine the location of obstacles and relays the information to the user by vibrating buttons on the unit’s handle. The user interprets the vibrations to determine the direction and distance to the obstacle.
Perhaps technology will one day allow the unit to be built into one’s shoes or clothing and make the whole process more passive and easier on the user.
Sound Foresight has a short flash video demonstrating the device.
