Sam Colley is joined by father and son inventors Peter and Rohan Rickards.

Along with Vision Australia's Kathy Letch, Peter and Rohan joined Talking Vision to tell us about Sensaball, their adaptable multi-directional white cane tip designed to give improved feedback, reduce friction and vibration and interact more intuitively across different surfaces.

Sensaball is still in the Kickstarter stage but if you'd like to find out more or make a donation you can head to the Sensaball website to keep updated.
