Abstract:
Methods, systems, and computer readable media are disclosed having methods for correcting a location of a touch sensed by a capacitive touch screen when using a stylus, especially an active electronic stylus. The various corrector methods correct touch locations such as manufacturer's built-in offset designed for fingertips, touchscreen drive/sense electrode banding, stylus angle offset, parallax, long linear stroke smoothing, and/or loop smoothing. The corrector methods used may depend on the stylus model and/or the tablet model detected. The corrector methods may configure themselves to conform to the stylus model and/or tablet model detected.
