U cannot get the sensing and the light output at the same location.
The reason being that wherever u include touch sensing, u would b adding aluminium foil or some other thin metal sheet either on the surface or beneath. The foil/sheet wont allow the LED light to pass through!!
It didnt matter much in case of the Robot design <until We would want to touch the Eyes itself to get them glowing >
Follow the pics below to see where did I place the sensing and the outputs. [The darker areas are those which have the foil beneath and are capable of sensing]
Try to make the whole thing work more intuitively by putting some time for designing it.
