1. A method comprising:
- receiving, by a computing device, an input responsive to a user contact with a surface of a first layer of a touch screen, the first layer comprising one or more sensors configured to sense the user contact;
generating an input signal associated with the input;
providing tactile feedback responsive to the user contact via one or more micro electromechanical machines (MEMs) included in a second layer of the touch screen, the second layer of the touch screen being below the first layer of the touch screen; and
providing visual feedback via a third layer of the touch screen based, at least in part, on the input signal, the third layer of the touch screen being below the second layer of the touch screen, wherein the first layer and the second layer are substantially transparent and wherein the visual feedback is visible through the first layer which is sensitive to the user contact and through the second layer configured to provide the tactile feedback;
wherein the visual feedback comprises highlighting, enlarging or moving a visual representation of an image associated with the input, andwherein receiving the user contact with the surface of the first layer comprises;
receiving a user touch against the surface of the first layer,inducing a voltage across the second layer by compressing at least one piezoelectric crystal in the second layer in response to the user touch against the surface of the first layer, andinducing the tactile feedback provided via the one or more MEMs using the voltage induced across the second layer.
