Abstract
A touch screen device includes a panel; a sensor coupled to the panel for detection of a force applied to the panel and a data processor coupled to the sensor for processing data transmitted by the sensor upon detection of the force. The sensor is provided to be co-deformable with the panel for detecting a deformation of the panel itself as a result of the force being applied. This avoids the use of a rigid frame as in conventional devices, saving weight, costs and components, and reducing manufacturing problems. The sensor means may comprise strain gauges that are physically integrated with the panel. Combined with a display such device presents a minimum parallax.
