Stereoscopic oscilloscope displays have been slow in gaining acceptance due in part to the past scarcity of applications, but perhaps mainly due to the apparent unavailability of a general-purpose instrument. But now the increasing use of computer-generated displays has begun to focus attention on them. The stereovectorscope, developed in our laboratories, is a new stereo oscilloscope with an initial 4-6 month availability. In addition to stereo, it provides linear perspective and two axes of manually-controlled spaceform rotation. Use of a proprietary spaceform rotation mechanism results in a simple, compact, lightweight instrument. One embodiment of the stereovectorscope is as a compact desktop laboratory instrument, designed to be viewed in the same manner as a stereo microscope. It has provisions for connecting a large-screen monoscopic monitor for group viewing. One immediate application is as a device for displaying vectorcardiograms. Another immediate application is as an OEM device for displaying computer-generated spaceforms. In this application, the stereovectorscope frees the computer and programmer from the requirement to provide rotation, perspective, and stereo transformations. In all applications it provides a highly natural man-machine interface for spaceform rotation via its "integrated" rotator.
