Abstract
An apparatus including a first sensor configured to couple capacitively to a stylus when said stylus is in proximity to the first sensor, capacitive coupling between the first sensor and the stylus configured to generate a first touch input signal to enable detection of a first touch input; and a layer configured to couple capacitively to the stylus when said stylus is in proximity to the layer, capacitive coupling between the layer and the stylus configured to provide haptic feedback, wherein the layer is positioned adjacent the first sensor, the positioning resulting in capacitive cross-coupling between the first sensor and the layer, and wherein the layer includes a first aperture configured to reduce the capacitive cross-coupling.
