A touch sensitive screen 12 having a face that receives a user's hand-writing 20 via a hand-held stylus 18, wherein the screen 12 vibrates so as to transmit the vibration to the stylus 18 to simulate the sensation of writing on paper. The apparatus may modulate the amplitude and period of the electrical signal applied by the vibration exciter 16. A bending wave vibration may be applied to the screen. It may also have sensors 17 to sense the velocity of movement of the stylus over the screen 12 and modulate the vibration according to the sensed velocity. The device may make use of sampling, filters and simulation models during data manipulation. The device may vibrate the screen at a particular frequency to produce a sound effect simulating that of a pen, pencil or other writing implement writing on paper. |
