I started of by building a circuit of 8 infrared LED´s. When the surface is touched the LED´s light up and the camera underneath the surface reads the lightest spot of the polycarbonate sheet. I choose to use MDF wood for my prototype and graved my name and the name of the project into the sides of the product. First I had to get the LED´s to work and then to place them at the side of the sheet so it would light up. I spend quite a lot of time constructing the product and finalizing it. I used processing to make the interface, when the camera reads the brightest spot of the surface, processing reacts with waves around the brightest spot.
