'Haptic baton' offers new hope for blind musicians

A conductor’s baton has been created that allows the visually-impaired to follow its movements, opening up the potential for blind people to join more orchestras.

The ‘Haptic Baton’ contains sensors that pick up even slight motions. These are then transmitted via radio signals to vibrating devices attached to musicians’ wrists or ankles. 

They vibrate and buzz in different ways to indicate to the player the pace and dynamics the conductor wants.

Violinist Abie Baker, who went blind as a child due to a cataract operation, said she was confident that with the device she could start playing her instrument at the same time as others.

“In the past, we’ve been reliant on hearing sounds around us. So I’ve been playing in a violin section and I’ve been reliant on hearing the other musicians putting up their instruments and then guessing roughly when to come in,” she told Reuters.

“So this is brilliant because there’s no need to count in or anything. I can literally just feel a buzz or two and then know to come in and I can come in confidently knowing that it’s right, which is amazing,” she added.

When playing as a soloist, blind pianist Kevin Satizabal said he has previously had to sit close to the conductor and listen for their breathing to know when to begin.

“But if you’re in a big orchestra and you’re miles from the conductor, that’s going to be really, really difficult information to pick up and this technology essentially plugs you into the conductor’s movements, which is really exciting,” he said.

“Orchestras won’t have any excuse not to hire visually impaired musicians because the technology’s right there allowing them to be an integral part,” he added.

The Human Instruments device was developed by designer Vahakn Matossian. He was inspired by the ‘Beat Buzz’ baton which was created by his father, composer Rolf Gehlhaar, in 2017.
