People who are visually impaired miss out at firework displays.
But a new prototype system lets them sense the explosions via touch.
Feeling Fireworks, created by Paul Beardsley of Disney Research in Zurich, Switzerland, and his colleagues, relies on five jets that fire patterns of water at the back of a large screen on which users place their hands.
The resulting vibrations mimic expanding dots of light.
“For rockets, one feels pulses of vibration that travel up the tactile screen with stronger vibrational explosions at the apex,” says Beardsley.
