The images displayed on the lumbar belt can come from both the 3D sensors located on the glasses and the screen of a computer. They are then adapted for tactile restitution, then conveyed as sensory information by the nerves to the visual cortex of the brain. They are then treated in the same way as if they came from the eyes. This new source of information is naturally interpreted whether one is blind from birth or not. The system adapts to each user and their level of control of the device. It works both indoors and outdoors, whether you are in the middle of nature or in the corridors of the metro at peak times.
As with learning to read or ride a bike, a learning
phase is necessary to master the device. The various software improvements have made possible to shorten this
time as much as possible.
After 10 minutes :
« For the locomotion task, despite the short training time (10 min), participants walking with the belt and the white cane detected obstacles significantly more than when they were only carrying their white cane or only wearing the belt. »
« 10/13 participants felt that the belt was useful or very useful for moving around. »
Quotes from the Streetlab report
After 1 or 2 hours, the mental load is reduced and perception becomes more and more
After about ten hours of use, users can perceive up to 10 meters away realise the number of activities that become much more accessible to them. The mental load becomes zero and perception becomes a reflex, which makes the device very relaxing to use.
