It looks to be possibly an exciting new advancement, and as a prototype I think it is on its way. However due to the fact that the very first person
in the video runs into a chair while using it, I think it may need some more work.
I invented a cane that uses infrared and ultrasonic sensors to see objects up to 15 feet away. There are blind people in the video using the cane for
the first time. Most are able to avoid all obstacles without more than a minute of practice feeling the vibrations in the handle.
The cane works by sending out sound and light waves and bouncing them off targets in front of the cane. As you approach an object the long range
sensor (Ultrasonic) sends a slight vibration to the forefinger that increases as you approach an object or wall etc. The intensity of the buzzing
increases until you get within reach of an object (3ft) and another buzzer in your middle finger kicks in much stronger than the first long range
buzzer . This gives the user depth perception.
The user can stand in the middle of a room without knowing the layout, stand up and energize this cane and find the exit without taking a step or
touching anything in the room. With a little practice the user will be able to identify objects easily without ever touching them. Some objects are
hard to differentiate, but it will be easy to tell a chair from a table or wall and a hallway from a closet. Depth perception allows a 15 foot view of
the user in any direction simply by pointing the sensor in that direction.
