Bristol innovation challenges regular touchscreens with new spray-on technique

A team at Bristol has challenged the idea that touchscreens are limited to 2D and rectangular shapes by developing an interactive display that can be sprayed in any shape.Inspired by the way an artist creates graffiti on a wall and using a novel combination of sprayable electronics and 3D printing, the technique, called ProtoSpray, allows the creation of displays on surfaces that go beyond the usual rectangular and 2D shapes.
