A touch-screen is an electronic display that locates and captures the contact of objects within the display area. Touch-screens can be divided in two main types: those oriented to finger-input and the ones oriented to styles. Touch-screens of stylus oriented hand-held devices are based on a resistive principle and are not oriented to operation with the user fingertips. Two separated metallic layers are connected when the screen is pressed. The position of the contact point can be accurately detected, but only when the stylus is in contact with the surface, contrary to pen tablets.
