First Claim
1. A touch-sensitive device for scrolling a document on a display screen, said device comprising:
- a central scrolling area extending along a longitudinal axis; and
first and second end scrolling areas positioned along the longitudinal axis on opposed sides of the central scrolling area, said first and second end scrolling areas being physically separate and spaced from the central scrolling area; and
first and second scroll input surfaces positioned immediately adjacent to said central scrolling area, and on opposing sides of and spaced from said central scrolling area in a direction perpendicular from said longitudinal axis, said first and second input surfaces enabling the scrolling of a document in opposite directions along a first axis.

Abstract
A touch-sensitive device for use as an electronic input device for controlling by scrolling the visible portion of a document or image relative to a display. The device can include various improved configurations such as physically separate opposed input surfaces at opposite longitudinal ends and/or lateral sides. The end regions of a touch sensitive surface may be rounded and/or tapered to provide relative positional feedback to the user. Tactile positional feedback can also include surface texture changes on the scrolling area and/or changes in the surface of the frame in the region immediately adjacent the scrolling area. The touch sensitive areas may be provided within a split alphanumeric section of an ergonomic keyboard to enable scrolling without the user having to remove his or her hands from the alphanumeric section.

23. A system for scrolling a document on a display screen, said system comprising:
-
a first touch-sensitive device having an elongated touch sensitive input surface; a second touch-sensitive device having an elongated touch sensitive input surface, said second-touch sensitive device being spaced from and adjacent to said first touch-sensitive device; and a physical divider disposed between first and second touch-sensitive devices, said divider having a contoured edge immediately adjacent the elongated touch sensitive input surface of at least one of said first and second touch-sensitive devices; wherein said contoured edge is sawtoothed shaped assisting the user in locating a position between a top and a bottom of at least one of the first and second touch-sensitive devices. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31, 32)
