网页设计中的色彩运用原则与技巧

网页的色彩是树立网页形象的关键要素之一。当浏览者观看网页时,首先看到的就是网页的色彩搭配,在不经意间,浏览者对网页的印象就从此固定下来了。在实用美术中常有“远看色彩近看花,先看颜色后看花,七分颜色三分花”的说法。这也说明在任何设计中,色彩对视觉的刺激起到第一信息传达的作用。既然色彩可以产生如此大的作用,那么在具体运用中是不可以随心所欲、任意发挥的,它需要有一些原则可供参考,在设计过程中也会有各式各样的配色技巧,这种搭配不仅体现在整体感觉上,还体现在网页的各个要素之间色彩的运用。     

Photoshop工具的使用技巧浅析

AutoCADR12使用技巧

1图层（LAYER）的使用技巧在一般的手工绘图中，只有一张图纸，没有图层可言。但在AutoCAD中，用户却可以通过图层Layer命令将一张图分为若干层，以便于检查和控制。在不同的图层中，可以定义不同的颜色、线型等。因此建议操作人员在建立图层时要养成一个良好的习惯，即不要以1，2，3……等阿拉伯数字作为层名，这将不便于以后查找图层，最好以图层实际用途的英文名称来作为层名，如：DAS（DASHED虚线）层即虚线层，进入此层无论画什么线如：直线、圆、弧等都是由虚线构成的；CEN（CENTE中心线）层即中心线层；HID（IDDEN隐藏…

Brush up your painting skills

Most present-day interactive paint applications lack the means of adequately capturing a user’s gestures and translating them into realistic and predictable strokes, despite the importance of such a mechanism. We present a novel brush design that adopts constrained energy optimization to deform the brush tuft according to the user’s input movement. It incorporates bidirectional paint transfer and an anisotropic friction model. The main advantage of our method is its ability to handle a wide range of brush tuft shapes that are animated using a freeform deformation lattice, which is associated with the tuft’s geometry. This way, almost no conditions or limitations are placed upon the appearance of the brush. Examples range from round brushes modeled as polygon meshes, to flat brushes with individual bristles. Less common deformable tools that are used to apply or remove paint on the canvas, like sponges, can be created as well. The model is integrated in our interactive painting system for creating images with watery paint.

How consistent is your web design?

Previous studies have indicated that when interfaces are designed consistently with regards to structure and physical attributes, higher performance and lower error rates are achieved than when interfaces are designed inconsistently. The objective of the current study was to develop a methodology to measure all aspects of computer interface consistency and assess the impact of linguistic inconsistency of interface design on user performance. Based on the background literature, seven factors were identified as affecting overall consistency. Based on this identification, a structured questionnaire of 125 items was developed and a factor analysis was conducted which reduced the number of items in the questionnaire to 94 and identified the following nine factors which contribute to consistency: text structure, general text features, information representation, lexical categories, meaning, user knowledge, text content, communicational attributes and physical attributes. A series of four experiments were conducted with 140 subjects using four different tasks and eight different interface types. The internal reliability of the questionnaire was 0.81, and the inter-rater reliability was 0.75. The instrument effectively identified all of the inconsistencies in interface designs. The instrument can be utilized both as an evaluation and as a design tool for Web-based interfaces.

Integration of metacognitive skills in the design of learning objects

Recent studies have demonstrated that specific instruction about metacognitive strategies improves achievement, the accuracy of knowledge monitoring, and the application of learning strategies in hypermedia environments. However, there are no models to date for instructional designers who design and develop learning objects for the incorporation of specific scaffolds to aid student reflection about their metacognitive skills; thus making it difficult to identify tasks to orientate learners in improving such skills. In this paper, we propose the use of specific ontologies as the basis for incorporating information about metacognition in learning objects so that a Learning Management System can select and recommend tasks designed for the development and/or improvement of the learners’ metacognitive skills within the context of e-learning.     

基于用户认知能力的自助服务终端界面交互设计方法

大众用户认知能力的多样性问题一直是自助服务终端界面交互设计领域的一大挑战。基于分布式认知理论对自助服务终端界面交互活动进行分析和建模, 确定人机交互过程中交互活动和信息呈现之间的关系, 并在此基础上提出基于用户认知能力的自助服务终端界面交互设计方法。采用这种方法, 设计人员首先要进行用户调研, 识别出需要照顾的用户群体, 然后进行认知能力分析, 建立用户认知负荷模型, 接下来描述用户的交互行为, 确定基本的交互框架, 再运用通用可用性设计方法建立交互设计矩阵, 提出交互设计方案。以酒店自助服务终端为实例, 采用该方法制定设计方案, 通过与传统方法形成的设计方案进行对比, 验证所提设计方法的有效性。这种交互设计方法能够帮助设计人员开发易于大众用户理解和使用的自助服务终端界面, 降低用户的认知负荷, 更好地满足自助服务终端用户的认知多样性需求。     

Wang laboratories' VLSI design strategy or Putting blinders on your engineers keeps your horse in the race

The article discusses the rationale used to make the decision to implement a constrained design capability for VLSI in Wang. A CAD/CAM system will be put in place that will permit product designers to achieve design and manufacturing turn-a-round times that are consistent with a product development cycle of 18 to 24 months. The functional requirements of the various subsystems are discussed as well as those for the excutive, the data base, and the audit capability. The latter capabilities are necessary to achieve a controlled constrained design environment.     

Concept mapping your Web searches: a design rationale and Web-enabled application

Although it has become very common to use World Wide Web‐based information in many educational settings, there has been little research on how to better search and organize Web‐based information. This paper discusses the shortcomings of Web search engines and Web browsers as learning environments and describes an alternative Web search environment that combines a concept mapping and a data mining technique to address their drawbacks.
