Dolphin-inspired technology helping the blind to ‘see’
“The Sixth Sense, inspired by bats and dolphins, will transform the lives of visually impaired people by giving them more independence,” said Brian Mwiti Mwenda, who saw the challenges facing blind students at his school in Kenya and was inspired to try to make their lives easier.
He created a small, handheld device that uses ultrasonic sensors to mimic the echolocation used by animals such as bats and dolphins, which he’s now testing with members from the Kenya Institute for the Blind. The device vibrates to warn the user when they’re close to an object, with the frequency of the vibration increasing as they approach it. There’s also a distress button, which can send a text with the person’s location to a preset contact
