A system and method for sharing and manipulating digital content allows users an intuitive mechanism with which to interact with touchscreen devices. A provided device with short-range wireless connectivity can interact with a mobile device by providing physical contact points that can be moved or adjusted to interact with displayed content. A series of the physical contact points distributed about the perimeter of the provided device allows an application to collect data regarding the position and orientation of the provided device placed upon the screen of the mobile device. A second set of physical contact points, also made of conductive material, contains at least one individual contact point that functions as a capacitive ‘button’ when the user touches it. Upon placement of the provided device on the capacitive screen of a mobile device, real-time tracking of the changing touch patterns can provide a more intuitive interface for handling digital content.

A method executable by a touch screen processing module of a touch screen includes detecting, via one or more drive-sense circuits of the touch screen, one or more changes in electrical characteristics of one or more electrodes of the touch screen, determining an interface area of the touch screen based on location of the one or more electrodes, associating the interface area with a passive pen, and interpreting the one or more changes in the electrical characteristics as one or more impedance values. When the one or more impedance values is in a first range, the method further includes interpreting the one or more impedance values as a touch. When the one or more impedance values is in a second range, the method further includes interpreting the one or more impedance values as a pressure measurement.

A touch sensor detector system and method incorporating an interpolated sensor array is disclosed. The system and method utilize a touch sensor array (TSA) configured to detect proximity/contact/pressure (PCP) via a variable impedance array (VIA) electrically coupling interlinked impedance columns (IIC) coupled to an array column driver (ACD), and interlinked impedance rows (IIR) coupled to an array row sensor (ARS). The ACD is configured to select the IIC based on a column switching register (CSR) and electrically drive the IIC using a column driving source (CDS). The VIA conveys current from the driven IIC to the IIC sensed by the ARS. The ARS selects the IIR within the TSA and electrically senses the IIR state based on a row switching register (RSR). Interpolation of ARS sensed current/voltage allows accurate detection of TSA PCP and/or spatial location.
