Imagine feeling the dazzling Disney fireworks display — when you cannot 
see them.

Disney Research is working on a way to share the fireworks experience 
with the blind and visually-impaired.

The system uses water jets that spray onto a screen, which are synced up 
with the show in the sky.

Feeling Fireworks is aimed at making fireworks more inclusive for blind 
and visually impaired users, in a novel experience that can be shared by 
all. Tactile effects are created using directable water jets that spray 
onto the rear of a flexible screen, with different nozzles for different 
firework effects.

It is low-cost and allows for dynamic tactile effects to be rendered 
with high spatial resolution. A user study demonstrated that the tactile

effects are meaningful analogs to the visual fireworks that they 
represent, with sighted users able to label the correct correspondence 
of tactile-to-visual effects by a large margin over chance. Beyond the 
specific application, the technology represents a novel and 
cost-ffective approach for making large scalable tactile displays, with 
the potential for wider use.
