PowerPoint演示文稿中交互性的实现

在ＰｏｗｅｒＰｏｉｎｔ演示文稿播放时,默认的是幻灯片按物理顺序播放,当然,我们可以在演示过程中通过鼠标右键,在弹出的快捷菜单中来定位下一张要播放的幻灯片;也可以通过菜单命令“幻灯片放映”中的“自定义放映”来重新定义播放顺序,但总显繁锁且缺乏交互性,不能满足演示中的多种需要。事实上,ＰｏｗｅｒＰｏｉｎｔ提供了很强的超级链接功能,灵活运用这一功能,就能制作出满足各种要求的有较强交互性的演示文稿。 所谓超级链接就是将幻灯片中的某些对象（可以是文本、图形、表格、图表、图片或动作按钮等）设置成特定的索引标…     

探讨如何将ppt演示文稿里的文字转换成word文档

在日常生活和工作中,ppt演示文稿和word文档都是人们最常用的办公软件,由于其具有强大的办公功能,辅助人们解决大量的办公问题,因此受到人们的欢迎,应用范围十分广泛.但同时也有着明显的制约之处,所以有时就需要将ppt演示文稿中的文字转化成word文档,以方便人们在工作中使用来处理各种公务.     

PowerPoint中实现超链接的几种方法

所谓超链接是指将幻灯片中的某些对象(包括文本、图形、表格、图片或动作按钮等)设置成特定的热对象(也称热物体),演示文稿时,只要鼠标移过或单击这些热对象就可跳转到指定的幻灯片、另一份演示文稿、某一音频和视频片断,或激活某一应用程序,甚至打开Internet上的某一主页,大大增强了演示文稿的交互性、灵活性和趣味性.

After the package is situated in the general framework of network synthesis, its general objectives are described. A detailed presentation is given of the package structure, user interaction, input and output. Examples are included to illustrate terminal interaction and program output.     

Teaching, Exploring, Learning—Developing Tutorials for In-Class Teaching and Self-Learning

This paper presents an experience report on a novel approach for a course on intermediate and advanced computer graphics topics. The approach uses Teachlet Tutorials, a combination of traditional seminar–type teaching with interactive exploration of the content by the audience, plus development of self-contained tutorials on the topic. In addition to a presentation, an interactive software tool is developed by the students to assist the audience in learning and exploring the topic's details. This process is guided through set tasks. The resulting course material is developed for two different contexts: (a) for classroom presentation and (b) as an interactive, self-contained, self-learning tutorial. The overall approach results in a more thorough understanding of the topic both for the student teachers as well as for the class participants. In addition to detailing the Teachlet Tutorial approach, this paper presents our experiences implementing the approach in our Advanced Computer Graphics course and presents the resultant projects. Most of the final Teachlet Tutorials were surprisingly good and we had excellent feedback from the students on the approach and course.     

软件性能工程方法在交互式软件开发中的应用

在诸多交互式软件系统中,包括软件开发工具及基于万维网的工具,性能问题是至关重要的.然而在软件开发过程中,性能问题并未得到足够的重视.主要目的是展示一种有效方法, 使得经过细致设计后交互式软件有满意的性能.展示如何应用软件性能工程方法于交互式软件工具开发中,特别注重在设计阶段的性能估算及其在决定实现方案时之效果.除了源于软件性能工程的严格的量化估算方法,提出性能亦可半量化或非量化方法进行有效而经济的估算. 基于结果的描述,最终建议为源于软件性能工程方法学中苛求采用系统环境参数进行细化定量性能估算未必是惟一手段.演示了在软件工具开发早期阶段中一种用以评估性能的基于分析和实验的有效综合途经.希望能反映出了良好的实验计算机科学之本质.     

Research issues in perception and user interfaces

Current visualization tools are capable but still require too much visualization knowledge on the user's part. This requirement restricts the user in what is possible. Nor do the tools take account of what is known regarding cognition and perception. The authors focus at on three things: presentation of information to best match human cognitive and perceptual capabilities, interactive tools and systems to facilitate creation and navigation of visualizations, and software system features to improve visualization tools     

Interactive Explanation of Software Systems

This paper describes an effort to provide automated support for the interactive inquiry and explanation process that is at the heart of software understanding. A hypermedia tool called I-Doc allows software engineers to post queries about a software system, and generates focused explanations in response. These explanations are task oriented, i.e., they are sensitive to the software engineering task being performed by the user that led to the query. Task orientation leads to more effective explanations, and is particularly helpful for understanding large software systems. Empirical studies of inquiry episodes were conducted in order to investigate this claim: the kinds of questions users ask, their relation to the user's task and level of expertise. The I-Doc tool is being developed to embody these principles, employing knowledge-based techniques. The presentation mechanism employs World Wide Web (WWW) technology, making it suitable for widespread use.     

Could a laptop computer plus the liquid crystal display projector amount to improved multimedia geoscience instruction?

In this study, a multimedia computer‐aided tutorial (MCAT) on the topic of debris‐flow hazards was developed for senior high‐school students in Taiwan. The format of the new course is a blend of whole‐class presentations, interactive discussions among the teacher and students, and classroom activities using the MCAT software. The whole‐class presentation was presented using both a laptop computer and a high‐resolution liquid crystal display projector to display the MCAT contents on a large white screen in front of a whole class. Besides, class discussions between the teacher and the students and among students were also embedded in the teaching format. Students' earth science learning outcomes were evaluated by administering an achievement test and a survey of attitudes towards the earth science subject before and after the course. The results indicated that MCAT accompanied by the current ‘interactive whole‐class teaching’ form could significantly help the students' grasp of earth science concepts and greatly improve their attitudes towards earth science.     

True multimedia presentations: A case study

This paper describes work undertaken as part of a three-stranded project. The main deliverable will be a suite of software tools, classes and components, as well as teaching resources and methodologies to facilitate the production of intelligent multimedia tutoring systems.

The three strands of this project explore differing aspects of multimedia, and while they stand as separate pieces of work in their own right, they also form the building blocks of the final deliverable, which is an intelligent tutoring system. Intermediate outcomes include a multimedia shell and the Manley Group Demonstrator.

This paper focuses on the design and development of the “true multimedia” demonstrator that has now reached the stage of being a fairly mature prototype. It is used commercially by a communications company to illustrate the varying levels of sophistication which can be achieved in presentation systems and provides an exemplar demonstrating the varying degrees of functionality possible using current technology. The main requirement in the design and implementation has been usability both for end users and content developers.

Real-time control of the multimedia devices is achieved using sophisticated software which is tightly integrated with dedicated control hardware. The software can be used to produce canned presentations or highly interactive systems.

The system is installed in a dedicated presentation suite, thus allowing the true nature of multimedia to be demonstrated. It is scaleable in that it can be used to produce stand-alone portable solutions, highly interactive touch-screen controlled applications or complete multi-device high end presentations. This is achieved using the appropriate combination of software tools and hardware for a specific application.
