Abstract
This invention presents a system for adding unevenness to keyboards in touch screens. Said unevenness will help the user to better perceive the keys on which she is placing her fingers, therefore helping her to type faster and with higher confidence and accuracy. There exist several ways to add said unevenness. In one of them, a thin sheet is placed upon the touch screen, said sheet comprising several openings or cavities. When the user moves her finger over said openings, she will, by her sense of touch, perceive the keys on which her finger is moving. The previous sheet can be transparent to allow seeing the keys located on the screen, but it can also be opaque if the keys are printed on top of it in corresponding position to the keys that are shown on the touch screen.
