Abstract
A computer dynamic cylindrical display provides a natural scrolling capability, giving the appearance of a much larger display in a very small size. The display encloses the electronics of the device and contains a simple weighted cam that senses roll (using rotation sensor much like in a mouse). When the cylinder is placed on a flat surface and rolled up and down, the pixel display scrolls in correspondence with the rolling movement, giving the visual feel of rolling a cylindrical magnifying glass across a finely printed document. A “snap-to” scrolling algorithm makes it easier for the user to stop right on the center of a line of text. Parallax algorithms compensate for the cylindrically wrapped text making it appear flatter. Twisting the cap adjusts the angle of presentation for when the user is not looking straight down onto the display. A touch sensitive overlay allows the user to select menu items or hypertext links as the display “rolls over” that line of text. The display also works without a flat surface (although not as naturally) by turning it while holding it in the air.
