In the current Palm Operating System, there is no system for providing feedback whenever the user interacts with the scrollbar. The Palm OS could benefit from the addition of visual indication that the user has engaged the scrollbar, especially since the scrollbar typically remains active when contact is maintained with the screen but not directly over the scrollbar area. Fig 1a. The scrollbar on this panel demonstrates how the Palm OS renders a scrollbar in an inactive state. Fig 1b. There is currently no change in the scrollbar to indicate that it has been activated. Fig 1c. In the current Palm OS, once the scrollbar has been activated, it remains active as long as contact is mantained with the screen, even if the stylus is not in direct contact with the portion of the screen dedicated to the scrollbar. This is confusing to the user.
