These feelings are not, of course, universal, but the amalgam does convey an image of the truly pleased user. As I talked with these enthusiasts and examined the systems they used, I began to develop a model of the features that produced such delight. The central ideas seemed to be visibility of the object of interest; rapid, reversible, incremental actions; and replacement of complex command language syntax by direct manipulation of the object of interest-hence the term \"direct manipulation.\" Examples of direct manipulation systems

Direct Manipulation: A Step Beyond Programming Languages

1. SUMMARY Computational Thinking [1] is a universal metaphor of reasoning used by both mankind and machines. From this perspective it has the potential to be a comprehensive umbrella for capturing the intrinsic nature of computing and conveying this in an understandable way to students and the general public. It represents a broad spectrum of reasoning across time and disciplines. Learning to count is a beginning of human computational thinking, followed naturally by arithmetic computation and abstract levels of symbol based thinking, often starting with algebra. Counting, arithmetic, symbols and abstract thinking are fundamental to the study of computing.

Basics of Software Engineering Experimentation is a practical guide to experimentation in a field which has long been underpinned by suppositions, assumptions, speculations and beliefs It demonstrates to software engineers how Experimental Design and Analysis can be used to validate their beliefs and ideas The book does not assume its readers have an in-depth knowledge of mathematics, specifying the conceptual essence of the techniques to use in the design and analysis of experiments and keeping the mathematical calculations clear and simple Basics of Software Engineering Experimentation is practically oriented and is specially written for software engineers, all the examples being based on real and fictitious software engineering experiments

During its long history the problem of reducing language to writing, and conversely that of interpreting written signs as language, has found a variety of solutions which still exist in the form of different writing systems. Written by a leading expert, this new textbook provides an accessible introduction to the major writing systems of the world, from cuneiform to English spelling. Florian Coulmas presents detailed descriptions of the world's writing systems and explains their structural complexities as well as the intricate relationship between written and spoken language. The book also provides a clear and engaging account of the history of writing and its consequences for human thought and literate society. This illustrated textbook includes questions for discussion at the end of each chapter, and an up-to-date explanation of theoretical issues. Clearly organised and engagingly written, it is the ideal textbook for use on courses on writing systems.

Writing Systems: An Introduction to Their Linguistic Analysis

Human?computer interaction (HCI) is the area of intersection between psychology and the social sciences, on the one hand, and computer science and technology, on the other. HCI researchers analyse and design-specific user-interface technologies (e.g. three-dimensional pointing devices, interactive video). They study and improve the processes of technology development (e.g. usability evaluation, design rationale). They develop and evaluate new applications of technology (e.g. computer conferencing, software design environments). Through the past two decades, HCI has progressively integrated its scientific concerns with the engineering goal of improving theusabilityof computer systems and applications, thus establishing a body of technical knowledge and methodology. HCI continues to provide a challenging test domain for applying and developing psychology and social science in the context of technology development and use.

This paper describes previous research on flowcharts and a series of controlled experiments to test the utility of detailed flowcharts as an aid to program composition, comprehension, debugging, and modification. No statistically significant difference between flowchart and nonflowchart groups has been shown, thereby calling into question the utility of detailed flowcharting. A program of further research is suggested.

Experimental investigations of the utility of detailed flowcharts in programming

Preliminary results on a system for delivering dynamic pion radiotherapy treatments are reported. The desired treatment volume is scanned across a small, focused pion beam using a computer-controlled treatment couch. A computer-controlled rangeshifting device modulates the stopping pion depth distribution in coordination with the couch motion to conform the dose to the shape of the treatment volume. For certain shaped tumors, the system can result in substantial normal tissue dose sparing and better field flatness as compared to irradiation by static treatments with broad beams. The characteristics of this new system, plus preliminary results for typical dose distributions as measured with thermoluminescent dosimeters (TLDs), are presented.
