Abstract
An information handling system with a haptic stylus may include a processor; a display device includes a digitizer sensor; the haptic stylus, including: a stylus housing; a microcontroller housed within the housing; a stylus writing tip operatively coupled to a pressure sensor and to detect a pressure on the display device of the information handling system; a spacer mounted around and operatively coupled to a circumferential surface of the stylus housing; a haptic film assembly operatively coupled to the spacer at the circumferential surface of the stylus housing and operable to provide haptic output via an EAP section to a user; and the microcontroller to: receive, as input, a detected pressure applied at the stylus tip from the pressure sensor; and provide the haptic output, via the haptic film assembly and EAP section, at an amplitude and a frequency mimicking an inking sensation.
