Abstract
An expandable and contractible stylus for interfacing with a touchscreen of an electronic device. The expandable and contractible feature allows for a stylus that contracts to fit into a stylus holder in a small handheld device and expands to facilitate its removal from a device and to fit more comfortably in a user's hand. It holds either its expanded or contracted position for any orientation in space. An expandable and contractible stylus may facilitate the user's experience and thus provide an advantage over other conventional styluses.
