Nkululeko Tunzi is an aspiring young entrepreneur whose innovations blaze trails and whose global vision seems to set him apart from his peers.
The computer science graduate from the Tshwane University of Technology (TUT) has invented an innovative walking aid that helps blind people navigate traffic.
The product, called Bulatsela, uses cutting-edge artificial intelligence (AI) and machine learning features to interpret surroundings.
“It helps detect objects and obstacles, creates a path and provides feedback to the blind person,” Tunzi said.
The idea came about after observing a blind elderly woman waiting to cross a street.
“I was in a bus and I saw a woman standing at the traffic light and she stood there for a while. The traffic light turned green, turned red and green again, and she did not cross the street. That’s when I thought that there must be a way [to help people in her position] and started with my research and looked at existing options.”
