Title: Tactile device for scrolling

Abstract: A tactile touch-sensitive device for use as an electronic input device for navigating an electronic document on a display device is described. The tactile aspect of the device provides a document location indicator, such as a protrusion or a depression, which may be perceived through the sense of touch. The device may incorporate additional features such as multiple modes of navigation, namely isotonic and isometric scrolling. Various sensors, such as force sensors and capacitive sensors, may provide the user with coarse and fine scrolling capabilities through different types of interactions with the scrollbar. The force sensors may allow the user to alter the rate of scrolling by adjusting the magnitude of force applied. Additionally, capacitive sensors may detect absolute positions of a user's finger movement and navigate through a document pursuant to those movements.
