Abstract
An input device, such as a stylus, can include adjustment capabilities that changes a size, shape, stiffness, or other characteristics of a portion of the stylus, such as the tip. The size, shape, stiffness, or other characteristics of a tip of the stylus can be altered to mimic characteristics of a particular writing or drawing tool. For example, the stiffness at the tip, the weight distribution, and/or moment of inertia of a particular tool can be simulated by altering the features of the stylus.
