Abstract
Disclosed are devices and methods of stylus devices that when in contact with a capacitive touchscreen and a grounding element, can vary the signal level detected on a capacitive touchscreen to create a more realistic writing experience. Disclosed are elements of a touchscreen stylus, which individually or in combination, can enable a touchscreen stylus to have at least one electrical characteristic that is variable. In this way the resistive link between the touchscreen and a grounding element can be varied to enable features such as a capability to vary the width of line being drawn, to vary a region of influence on the touchscreen and/or to vary a temperament of action. The elements of a disclosed stylus can include at least one mechanical feature to provide at least one electrical characteristic that is variable and/or at least one material in an arrangement to provide at least one electrical characteristic that is variable.
