Abstract

In designing electronic overlays or forms to be variably placed upon a sheet of paper or presented on a screen the relationship between various orientations can be difficult to perceive. A slide-rule calculator having a base and two coaxial independently rotatable wheels indicates: 1. the relative orientation of the overlay or electronic form with respect to a sheet of paper or screen, and 2. the relative orientation of the text and graphics to be included with the overlay with respect to the overlay and to the sheet of paper.

Graphic Orientation Slide-Rule Calculator

In designing electronic overlays or forms to be variably placed upon a sheet of paper or presented on a screen the relationship between various orientations can be difficult to perceive. A slide-rule calculator having a base and two coaxial independently rotatable wheels indicates: 1. the relative orientation of the overlay or electronic form with respect to a sheet of paper

or screen, and 2. the relative orientation of the text and graphics to be included with the overlay with respect to

the overlay and to the sheet of paper. The calculator wheels are apertured and carry indicia representing orientation such that the rotation of the two wheels allows the user to align the apertures with orientation-indicating legends for quickly perceiving the relative orientations between text and graphics, the overlay, and the sheet of paper or screen. The slide-rule calculator has a rectangular base rotatively supporting a pair of orientation-calculating wheels coaxially disposed about the wheel axis. The base also contains legends indicating the direction of paper travel through the printer with which the slide rule calculator is to be employed. Additional scale areas, such as metric and English units, machine units (pels or pixels) and typographic font height, can be disposed along the peripheral edges of the base. A help screen or other legends can also be printed on the base. The overlay orientation is determined by rotating the o...
