Real-time recognition of handprinted text

During the past 10 years, there has been considerable interest in the automatic recognition of handwritten and machine-printed symbols. Most of these studies have involved computer recognition of an already completed symbol; a few have involved special electronics for the analysis and recognition of characters or words as they are being written.

On-Line Computer Classification of Handprinted Chinese Characters as a Translation Aid

This paper describes a method for using sequential positional information to recognize handprinted Chinese characters, and a computer program which uses this method to provide a translation aid. The method is based on the fact that Chinese characters are drawn as a definite sequence of a few types of strokes. The program, which provides a direct man-computer communication via a RAND Tablet and a CRT display, simplifies using a Chinese dictionary by reducing the number of steps and the time required.

BIOMOD: an interactive computer graphics system for modeling

Many of those involved in improving the quality of life often model and simulate continuous systems as part of their work. For example, one group of investigators may model an oil refinery to learn how to produce a new fuel efficiently, while another may simulate a global weather model to determine the effect of burning large quantities of the fuel at high altitudes. An urban planning team may simulate the water flow in an estuary to discover the best location for a new sewage treatment plant or the effect of a proposed breakwater. A medical team may simulate the bodily distribution of drugs to determine optimal dosage amounts and intervals, while another team might simulate the blood-volume control system to design a more efficient artificial kidney.

Data management for clinical research

This paper discusses a prototype system intended for the personal use of physicians engaged in clinical research. In particular, the prototype is a highly integrated, interactive, minicomputer based data management and analysis system. The facilities offered by the system allow the clinical investigator to store, recall, analyze, and display his research data without resorting to computer programming. Modern data base techniques are available to the physician as aids in organizing, storing, and retrieving his data. The data base concepts are expressed in terms that are familiar to a clinical researcher.

Information processing needs and practices of clinical investigators: survey results

Although medical researchers were among the first to pursue the promise of computerization, clinical investigators, namely physicians who conduct research into the biology of human subjects and who evaluate the efficacy of new therapeutic measures, have not shared even modestly in the benefits so far available. With the expectation that improved information processing techniques and facilities can improve the quality and efficiency of clinical research and ultimately patient care, The Division of Research Resources (DRR) of the National Institutes of Health (NIH) has been sponsoring a scientific inquiry (called CLINFO) aimed at first developing a detailed understanding of the information processing needs and current practices of clinical investigators and then developing methods for generally and economically alleviating some of the most important needs. The CLINFO investigation team consists of clinical investigators (T. Graham Christopher, M.D. at the University of Washington, Arthur W. Nunnery, M.D. at the University of Oklahoma and Howard K. Thompson, Jr., M.D. at the Baylor College of Medicine), the authors and other information scientists at The Rand Corporation, and William R. Baker, Jr., the CLINFO Project Officer, and other staff members of the DRR.

Display terminals can help people to use computers

A user likes to think of a display-terminal screen as a working surface upon which he can create objects and with which he can view and easily manipulate these objects. He is interested in such objects as text, line drawings, data clusters, and natural scenes. In reality, such objects may be black-and-white or in full color, and may be 2-, 3-, or higher-dimensional.

Simulating PHYSBE with BIOMOD

GABRIEL F. GRONER received a BS in engineering with highest honors from UCLA in 1960, a MS in eZectricaZ engineering from Stanford in 1961, and a PhD in electrical engineering from Stanford in 1964. From Z962-Z964 he worked at Stanford EZectronic Laboratories on the theory and appzication of adaptive and statistical pattern recognition, and participated in the design and development of a speech-recognition machine. For the past seven years, Dr. Groner has been a member of the Research Staff of Rand’s Computer Sciences Department. He developed a reaz-time symbol recognition program that is used daily in a number of applications, and is presently directing the development of computer graphics software for modeling and simulation.
