Current means of locomotion
The first easiest way to travel is to support someone else.
This solution does not allow autonomy.
The second means of displacement is the classic use of the white cane.
It requires a good training supervised by a locomotion instructor.
The sweeping of the cane in front of the walker provides protection, but only the lower body 50 cm and does not allow him to anticipate obstacles. It is used as a travel tool by less than 5% of the population. This low rate can be explained by access to very poor rehabilitation services for visually impaired people over 20 years of age.
The third means of travel used in France is accompanied by a guide dog. It must anticipate and avoid obstacles at the height of man. The training of the dog is long and expensive and its duration of activity is of the order of 8 years. This solution concerns about 1% of the population. This means is also limited by poor access to rehabilitative care.
The optronic case is thus fixed on a CLASSIC WHITE CANE. The infrared acts on the wide field and the laser on a central vision so as to have a good frontal protection including for the small anti-parking black poles.
The user sweeps his white cane in front of him on a range of + or - 30 ° as he would usually do with the cane alone. In addition to the information on the ground given by the rolling tip of the cane, is added a vibrating information to detect passages. The range of the device is easily modifiable by the user according to the place in which it circulates and can reach 12 meters. The visually impaired equipped can move comfortably in autonomy and safety without the stress of a collision that can occur at any time.
To be able to use this material, criteria are required: solid bases in locomotion, training of about twenty-five hours spread over time by a locomotion instructor. The beneficiary does not own the equipment. It is loaned over an indefinite period during which the user has a follow-up of the equipment in case of breakdown or evolution. He also has a personal follow-up of his travel capacities at least every two years.
This solution currently concerns in France about 1% of the blind as the guide dog.
