How does it work? It’s pretty cool actually. The iPhone’s capacitive touchscreen display knows what we want it to do by reading where our fingers distort its electrostatic field. Halo simply uses a circuit layer to re-route that current, allowing your lower left touch to register in the top left corner.
Cool!
