Apple engineers file for patent on 'active' stylus
Engineers working for Apple have applied for a US patent on an "active" stylus, reports say. In most respects the concept is like any current stylus, but instead of simply blocking electric field lines on a capacitive touchscreen, the Apple stylus could generate an electric field, and/or act as a sense electrode for signals from drive rows and columns. The patent filing remarks that this could improve response on a touchscreen without "significant" extra cost.
