Patent number: 8462106Abstract: Systems and methods control resizing a presentation of an image on a flexible display. A user flexes a flexible display in a particular manner to control magnification or size reduction of the image presented on the display. The amount of magnification or size reduction of the image presented on a flexible display increases along with the absolute magnitude of flexible display flexing. The flexible display can be double flexed within a defined time to indicate that another action is to be taken, such as fitting the presently displayed document to the width of the flexible display or fitting the entire document to the flexible display. The direction of flexing, such as flexing in a concave or a convex direction, is a flexing characteristic that causes other desired actions.Type: GrantFiled: November 9, 2010Date of Patent: June 11, 2013Assignee: Research In Motion LimitedInventors: Alek Tziortzis, Bashar Jano, Alexander Hirsch
