Interactive Generation of Object Models with a Manipulator

Abstract: Manipulator programs in a high-level language consist of manipulation procedures and object model declarations. As higher level languages are developed, the procedures will shrink while the declarations will grow. This trend makes it desirable to develop means for automating the generation of these declarations. A system is proposed which would permit users to specify certain object models interactively, using the manipulator itself as a measuring tool in three dimensions. A preliminary version of the system has been tested.

Object description with a manipulator

Abstract: This paper presents an interactive system, called POINTY. The goal of this system is to solve problems encountered when a high‐level manipulator lanaguage, as AL, is employed. Those problems are related to the necessity of supplying any manipulation program with a complete description of the objects involved. The object description has an important role in any task description oriented language. In these languages the procedural part, which expresses the assembly steps, is reduced by increasing correspondently the descriptive part, which expresses the knowledge a program has about the physical world. An approach to the generation of object models is presented, and the system based on it is illustrated. The basic idea is to point to the objects with the manipulator for building an incremental model of the world, and then to generate the AL corresponding instructions. The preliminary experiences using it demonstrate that the object model part of an AL program can be easily obtained and tested.

Object models for computer-aided design.

Abstract: A computer aided design system must deal with large amounts of both spatial and non-spatial data. It must also provide quick graphic response to user interaction. If the CAD system is to support re...

Current Concepts of Object Relations Theory

Abstract: The Chairman, Mark Kanzer, reminded us that “Object Relations Theory” has become especially associated with direct observations on preoedipal phases of the mother-child unit. The difficulties in verifying reconstructions derived from adult treatment from these early phases and correlating them with the data of direct observations are well known. At the same time, object relations observers find it harder and harder to follow the child’s development as he grows older. Despite these difficulties, a solid core of interest in child development has inevitably characterized the history of psychoanalysis. Studies of the child’s actual object relations can no longer be considered “peripheral,” if indeed they ever were. Preoedipal reconstructions played a very important part in Freud’s own self-analysis. Later, when he developed a theory of instincts and their vicissitudes, he defined them in relation to the ego (or self, or subject) and the external world as objects. Differentiation and relatedness developed between self and objects as the personality matured. Kanzer then traced the modem phases of object relations thinking from Hartmann’s work through that of Jacobson, Kris, Anna Freud, Erikson, Spitz, Loewald, his own work, and others. Associated with the new emphasis upon object relations, a dyadic approach in the traditional treatment of adults became perceptible. Tracing transferences all the way back to early.
