Person e.g. blind person, assistance system, has optical sensor unit serving for surrounding detection based on surrounding data, where output of unit takes place in combination with position data

摘要

The system has a navigation unit (3) i.e. global positioning system-receiver, for position determination based on position data, where output of the navigation unit takes place via an output unit (8) i.e. audio output unit. An optical sensor unit (4) i.e. video camera, serves for surrounding detection based on surrounding data, where output of the sensor unit takes place in combination with the position data via the output unit. An additional sensor unit (5) serves for detection of position and/or viewing direction and/or turning rate and/or acceleration of a person. An independent claim is also included for a person i.e. pedestrian, assistance method.
