A graphical user interface uses scroll bars having a single pixel width and a much larger scroll button or thumb. Both the scroll bar and the scroll button may be controlled to have selective degrees of transparency so that they underlying image information may be seen under certain conditions. In one application, the scroll bar itself is invisible until a cursor approaches to within a specified proximity. The graphical user interface permit scroll bars to be displayed which follow an arbitrary path in either two or three dimensions.

Why it's free to use
- Filed September 16, 1998. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended September 16, 2018.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by September 16, 2020.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
