A brief description of an interactive computer graphical system that allows the user to enter a curve into an IBM 360/40 computer via a RAND Tablet and to try various ways of fitting, editing, and displaying the curve on an IBM 2250 display scope. Control is by the Tablet stylus exclusively, using software-sensitized areas for pointing and Groner's character recognition scheme (RM-5016) for alphanumeric inputs. (Presented at the ACM Symposium on Interactive Systems for Experimental Applied Mathematics, Washington, August 1967.)
This report is part of the RAND Corporation Paper series. The paper was a product of the RAND Corporation from 1948 to 2003 that captured speeches, memorials, and derivative research, usually prepared on authors' own time and meant to be the scholarly or scientific contribution of individual authors to their professional fields. Papers were less formal than reports and did not require rigorous peer review.
