Apple’s application for a ”Stylus with touch sensor,” as published by the U.S. Patent and Trademark Office, describes a next-generation input device that incorporates an array of capacitive touch sensors along its body to determine the position of a user’s fingers. Information gathered by these sensors can be interpreted as gestures for onscreen UI control.
In some embodiments electrodes might be installed in both longitudinal and circumferential arrangements wrapped around the body to facilitate accurate detection of multiple concurrent touch events, or contact with multiple fingers. The system is able to process both single- and multi-touch gestures, whoch can then be used to manipulate onscreen objects.
