An operating system for interactive terminals

Conventional operating systems have for many-years used the ideas of standard stream interfaces to peripherals. Multi-tasking has been used in order to give an efficient response while maintaining simplicity and flexibility for the user. This paper describes an extension to an operating system which makes similar facilities available for the control of interactive workstations, and also provides a command dispatcher which enables the straightforward implementation of arbitrary user-defined command languages. The current system has been written in BCPL to run on a PDP 11/45 handling a Vector General display, but the design is suitable for use with a variety of terminals, computers and languages.     

基于心智模型的儿童移动端编程平台研究

针对移动端市场,虽然培养儿童编程思维平台的种类比较繁多,但是由于对儿童认知心理学的忽视以及平台界面展示形式的单一,导致此类软件平台的儿童体验较差。因此,提出一种基于心智模型的游戏编程创作平台。在符合儿童心理学的基础上,结合心智模型分析儿童的需求,来设计平台交互界面,使得按钮、图片等元素不仅简单易懂,并且可以极大地吸引儿童的注意。与此同时,为了能让儿童快速地设计出具备简单交互功能的游戏,提出一种基于单链表结构的交互逻辑表达方法。在该平台中,儿童只需要拖拽图形元素,并设置其相关参数就可以完成游戏的开发。实验表明,该平台具有良好的实用性,大部分儿童都可以快速地开发出具有简单交互功能的游戏。该平台不仅调动了儿童主动交互的积极性,而且也提高了人机交互的易用性。

TREE: An interactive system for editing tree structures

Many existing systems provide extensive facilities for entry and manipulation of text. Typical of these are QED (Bell Telephone), TECO (MIT), TVEDIT (Stanford), and E (Yale). Text entry, insertion, deletion, search, and display are all performed interactively with a small number of key strokes. Unfortunately, similarly powerful and general interactive tools for editing of more general data structures have not been available.The system TREE provides these interactive editing facilities for tree structures. TREE enables insertion, deletion, copying, search, and display of any branch of a given tree structure. Any tree, whether a syntax tree or a decision tree, or a LISP program could be entered rapidly and changed quickly in TREE. The program itself is coded in PDP 10 fortran IV and will run with any of a number of inexpensive graphics terminals.

Data management challenges and development for military information systems

This paper explores challenges facing information system professionals in the management of data and knowledge in the Department of Defense (DOD), particularly in the information systems utilized to support command, control, communications, computers, and intelligence (C/sup 4/ I). These information systems include operational tactical systems, decision-support systems, modeling and simulation systems, and nontactical business systems, all of which affect the design, operation, interoperation, and application of C/sup 4/ I systems. Specific topics include issues in integration and interoperability, joint standards, data access, data aggregation, information system component reuse, and legacy systems. Broad technological trends, as well as the use of specific developing technologies are discussed in light of how they may enable the DOD to meet the present and future information-management challenges.     

Problem structuring methods in military command and control

In an authorized military hierarchy organization, the procedure of problem solving must be co-ordinated with the tasks of planning, directing, and controlling. In most combat situations, problem solving knowledge is acquired from an expert (commander) or a single group of experts (staff) in a military organization. Therefore, these multiple actors (commander and the staff), multiple perspectives (multi-expertise and knowledge types), incommensurable and/or conflicting interests (resource allocation and distribution among staff planning), important intangibles (ambiguous quantitative or qualitative apparatus), and key uncertainties (unexpected internal and external situations) are part of unstructured problem. In this article, military strategy and tactics are acquired as case knowledge, rule knowledge, and heuristic knowledge content in terms of representing combat formations and planning mechanism to support problem structuring and the solution of military command and control. By doing so, this article presents a knowledge-based system architecture, including case base, rule base, heuristic base, and learning paradigm, for the military command and control procedure with strategic guidance (commander’s strategy and tactics) and tactical planning (staff plans generation) system functions in terms of implementing problem structuring methods in military command and control.

Software ergonomics: effects of computer application design parameters on operator task performance and health

Abstract

Evidence is reviewed that the operating characteristics of computer application systems, in addition to physical characteristics of display units (CRTs), are the cause of many observed effects on operator health and task effectiveness. These effects are hypothesized to occur through changes in task structure, and the man-machine redivision of labour that results when computer application systems are introduced into work setting. First, the association between task dimensions and models of operator performance effectiveness and well-being are reviewed. Second, application system design parameters that affect task structure are identified. Then, empirical evidence supporting this three-part causal linkage—application system parameters to task characteristics to operator effectiveness and health—is presented. The findings suggest that by improving dialogue quality, taking advantage of two-way communication to reduce uncertainty, using smaller and less integrated systems and matching system performance to operator needs a job can be created that is likely to improve both operator well-being and effectiveness.     

Agent-oriented design of human–computer interface: application to supervision of an urban transport network

At the present time, the approaches found in the design of interactive systems use a modular structure, with the aim of achieving a better understanding of reactivity, flexibility, maintainability and reuse at the human–machine interface level. However, most architecture models are far more concerned with user-controlled applications and they do not consider the specificities of supervision applications in which the human operator acts as the controller and commander of an independent dynamic process. A multi-agent approach is a possible answer to this type of situation. The agent-oriented model put forward in this article is the subject of an application intended in the long term to supervise the user information system of an urban transport network.

Visualization for situational awareness

We focus on theater-wide situational awareness covering a large geographic area containing many military units. The Joint Operations Visualization Environment (JOVE), developed at Sarnoff to assist military decision makers, optimizes the display of tactical data for information presentation. JOVE uses three rear-projected displays driven from an SGI Onyx2 Infinite Reality2 computer. Stereoscopic display is available. A joystick, graphical user interface, and speech commands provide interaction. JOVE delivers accurate navigation through the model over a range of viewer positions. This case study describes techniques used for effectively modeling and navigating geospatial and tactical data for situational awareness. The visualization technology could be applied to commercial air traffic control, emergency management response, and geographic information systems as well

Traffic analysis and display for the San Francisco Vessel Traffic System

To help improve harbor safety in the face of increasing shipping volume and vessel sites, an experimental Vessel Traffic System has been designed, fabricated, and installed in San Francisco Harbor. The Traffic Analysis and Display portion of the system uses computer generated synthetic map and text displays to provide an interactive system for up to three operators. A series of services has been designed which enable the operators to obtain radar contact information and to enter, modify, and recall text information through a series of simple keyboard actions.

In addition to the interactive working displays, 4 supporting displays have been provided for designated map segments of the harbor, along with two alpha numeric displays for summary text information. A set of symbols has been developed to allow quick recognition of the vessel traffic situation by the operators.

A control computer connected to three interactive display computers and five passive display units provides complete radar contact processing and display, as well as quick response to independent operator requests for information or services. The operators can put vessels into any one of 3 basic categories which allows them to keep the vessels sorted and easily follow the progress of the important ones through the harbor.

A background program supplements the operator actions by looking for and reporting specific trouble situations, such as collision warnings, allowing an operator to concentrate on a particular situation without fear of missing a major problem elsewhere in the harbor.
