Mr Lucas has developed more intuitive interface than the current ones for blind people, called Siafu. It lays flat like a tablet and allows the user to fully interact with it by way of touch. The surface utilizes a conceptual material called magneclay or magnetized liquid. Which has the ability to morph upward into any shape via a controlled electromagnetic field enabling the device to create a braille surface for reading and even pictures in 3D relief.

The technology behind Siafu - Magneclay, is an oil based synthetic agent that possesses limitless morphing capabilities. It has a loose molecular structure but can be infinitely rearranged when acted upon by electrical and magnetic charges. As long as the charges acting upon it remain stable, the magneclay will hold its structural rigidity, allowing it to be touched without deformation.
