9 RealTime Assistance Prototype – a new Navigation Aid for blind people.pdf

15 m y v 12 m h 10 m x z d z 5 m Fig.4. Spatial coordinates of the object representing a displacement in a specific travel direction where the azimuth measurements are used. - Object height (h) – the elevation coordinates sound specifies the object height. - Object speed – is proportional to the pitch changing speed. Fig.5. Experimental scenario - Scene complexity – the acoustical system represents only one obstacle which is detected by the artificial Assistance Prototype required new effort and training, since vision system and classified as the nearest obstacle. the experiment with the Real–Time Assistance Prototype - Moving object – the transmission rate is proportional investigates the performances of the object detection for two to the object distance. This means that when the object types of scene
