Menus whose geometry is bounded by two radii and an arc
ActiveUS7210107B2Cathode-ray tube indicatorsSpecific program execution arrangementsGraphicsPointing device
Sector menus track a pointer's position as a pointing device is moved. Each sector menu is a geometric figure bounded by two radii and an included arc of a circle. Menu items are housed in segments formed from multiple radii cutting the sector menu. Users select menu items housed in segments by making a direction change from a trajectory course to pass over a desired menu item so as to invoke its operation. The sector menu lacks a segment, defining a devoid segment, which is oriented in a direction toward which the pointer is moving. Segments with different sizes are available to represent the likelihood that a user would choose a given operation in a corresponding menu item housed by a corresponding segment.

Vertices of an annotation are projected onto a surface of a (2D or 3D) model and reconnected to preserve the original appearance of the annotation. The result of our method is a new set of geometry for the annotation that geometrically conforms to the surface of the model. A plane is defined by the midpoint of the original line segment and the two projected vertices. This plane is used to create the new line segments that conform to the surface, e.g. by doing a “surface walk” between the projected points along the line defined by the intersection of the plane and the surface.
