- •
Tapping a cane on a paving is a substitute for visual information in spatial orientation.
- •
Analysed the acoustic cues generated by different materials impacted by the blind cane.

Introduced a new parameter to describe the acoustic contrast of paving materials.
- •
Good correlation with the perception of the signal by a sample of blind people.
