State-of-the-art sound tech could soon allow blind people to play ping-pong

SYDNEY, Australia — Folks with visible impairments could quickly have the chance to play desk tennis, because of superior acoustic know-how. This revolutionary strategy combines object monitoring with a speaker array to supply real-time, three-dimensional audio suggestions, based on scientists.

Presently, sports activities like desk tennis are sometimes inaccessible to people who’re blind or have extreme imaginative and prescient issues. Nonetheless, Phoebe Peng, an Engineering Honors pupil on the College of Sydney in Australia, is exploring strategies to allow folks with low imaginative and prescient and blindness to play ping-pong utilizing sound.

Her analysis makes use of neuromorphic cameras and a loudspeaker array, permitting gamers to find the ball and discern actions via auditory cues.

“The small measurement of the ball and desk, together with the motion of the ball in 3D house, are issues that make desk tennis tough to play for these with low imaginative and prescient and complete blindness,” says Peng in a media release. “Making this sport extra accessible whereas additionally exploring the potential of neuromorphic cameras had been my two greatest motivators.”

The researcher notes that neuromorphic cameras, which she employs in her research, are significantly efficient for tracking small objects like ping-pong balls. These cameras differ from conventional ones in that they monitor modifications in a picture over time, fairly than capturing full static photographs.

By strategically positioning two of those cameras, Peng can precisely monitor a ball in three dimensions in real-time. This knowledge is then processed by an algorithm that controls a collection of loudspeakers positioned alongside the desk’s sides. These audio system create an auditory illustration of the ball’s location.

Whereas the system reveals promise, Peng acknowledges that additional experimentation is important earlier than folks with imaginative and prescient issues can use it in precise gameplay.

“An ongoing technical problem is the matter of human perception of sound,” Peng provides. “There are limitations on how precisely folks can understand sound localization. What kind of sound needs to be used? Ought to the sound be steady? This can be a technical problem we’ll be tackling within the subsequent stage of growth.”

The researcher offered her findings on the Acoustics 2023 conference in Sydney.
