Abstract
Methods, systems and computer program products provide touch screen erasing. A touch device includes an eraser detector that configured to analyze one or more blobs comprising a plurality of detected signals caused by a conductive pattern in or on an eraser type of touch instrument in proximity to the touch device. Each detected signal may have an associated intensity and location on the touch device. A position detector is configured to detect a position of an eraser based on the locations of the plurality of detected signals. An orientation detector is configured to detect an orientation of the eraser based on the intensities of the plurality of detected signals. An eraser reporter is configured to report the position and orientation of the eraser to a content source (e.g., an application and/or operating system providing displayed content).
