Abstract: A stylus has a body portion and a tip portion coupled to an end of the body portion. The body portion defines a first cross-sectional area and is configured to be engaged by a user. The tip portion has a first end disposed adjacent to the body portion and having the first cross-sectional area, and a second end defining a second cross-sectional area different from the first cross-sectional area. The tip portion is formed from a flexible material that elastically deforms when placed in contact with a touch sensitive display to define an engagement surface that is input to the touch sensitive display. The engagement surface has a first size when the stylus is in a first configuration and a second size different from the first size when the stylus is in a second configuration.
