This article presents the system used for navigation and orientation of blind persons in
an unknown terrain. This system called
‘
Tactile Navigation System
’
constitutes a compensation
instrument for blind persons. It is composed from three basic elements: a
camera, a control unit
and a tactile activator. The tactile navigation system converts the image from the camera to the
tactile information and it transfers this information to the blind person. The blind person can
recognize by vibration of the tactile a
ctivator placed on the antebrachium whether he comes on
an impediment or if he can continue free walking. The main advantage of this system is the
possibility of detecting any individual impediment earlier than using other common compensation
tools, such a
s a simple blind stick, which is not a competitor with this device, but a helper. This
way the system facilitates the orientation of a blind person an in an unknown terrain. The article
describes in detail the overall composition and functionality of the s
ystem as well as the principle
and funct
ion of its individual elements.
