In the conventional studies on graphic interaction devices or systems, two important points remain. They are parallax elimination and display size enlargement. To give a solution for these problems, the device described in this report employs multiple laser beams as a display medium. Both the display part and the pointing part for the device are integrated at a thin translucent panel putted on the surface of a transparent digitizer of 370.0×370.0 mm width. Figures for display are stored in a memory unit having xy addresses of 1024×1024 with 8 bits depth per each address. The conversion between an address of the memory and a position for beam spot to display and indicate on the panel is difficult to compute. The report, however, proposes a simple approximation of the conversion for computing. Interaction experiments to certify functions of the device offer menu-driven commands on the panel. Using commands and point indications to display on the panel, interaction experiments demonstrates figures such as a sexangle with an inscribed circle by C^1 B-spline interpolation and hand-written symbols successfully on the large display panel of the device without no parallax.
