浅谈图与字在视觉传达设计中的分析应用

图形和文字创意是视觉传达艺术设计的重要组成部分,它有着自己的形成规律和组织形式.如何进行视觉传达设计,是设计爱好者和设计师所关切及不断追求的问题.因此,只有切实有效、科学严谨、创意无限的思维方式才能推动设计的不断进步与发展.随着社会的进步,人们生活水平的不断提高,在新的时代背景下对于视觉传达设计又有着新的要求.因此,就要求我们的设计师与时俱进,不断更新自己的设计理念和设计方法,对于图形和文字进行再加工,对于图形和文字进行再研究,只有这样的设计,才是依据时代性和发展性的好设计.本文就图形和文字在视觉传达设计中的应用方法,去展望图形和文字创意在现代视觉传达艺术设计中的发展趋势.     

谈现代包装设计中的文字设计

包装设计的视觉表达要素主要有图形、文字、色彩、肌理、造型等,而文字作为最主要的视觉表达要素之一,不仅承担传达观念与信息的重任,而且它的视觉形象也展现着丰富的形式化内涵。字体作为一种符号化的表现形式,具有非常强烈的表现力和感染力。本文从文字设计负载的商品信息,文字设计所营造的视觉流程,以及文字设计所承担的传承传统文化的使命三个方面,论述了自己的设计观点。     

文字符号的图形化初探

作为信息传播媒介的文字符号在当前信息日益图形化的历程中,逐步被调整其视觉形象,使得文字符号视觉特征更具有时代气息,这触发了文字图形本身的视觉巨变,为视觉信息多元化提供了新的探究方向。     

文字图形中民族情感因素的表达

在当今图形化时代,文字与图形在设计领域尤其是平面设计当中,有着举足轻重的作用。中国的汉字延续传承了几千年,经历了多个历史阶段,具有独特的视觉魅力,从视觉传达角度说,汉字是在原始图形基础上演变而来的,其本身就具有图形之美,同时,又带有一定的民族情感因素,本文主要通过对文字图形化的民族特性、文字与图形的互融、文字图形化的视觉表现来论述文字在图形化时代的可行性。     

设计与非设计——重庆市区街头文字考察启示录

本文以城市街头文字为研究着眼点,以视觉文化的角度对重庆城市街头文字进行考察。这些文字本身所传递的信息不是我所关注的重点,而是把这些文字当作视觉造型,通过解构街头文字的表象来探求他们所呈现出来的特殊视觉形态,期望从中获得一些设计元素和设计表现方式的启示。另外,通过非设计的偶然形态与设计的必然形态的对比,思考街头文字的文化现象与设计的关系。     

英文字体的造型特征及应用

英文文字是英语的视觉信息符号,英文文字的设计被广泛地运用在广告、招贴、标志、书籍装帧等视觉传达领域,是视觉传达设计的重要组成部分。英文字体按照不同的造型特征进行分类,并因其不同的表现形式,被应用在不同的领域,以期达到最佳的视觉效果。     

设计中的视觉心理表现分析

在设计中,视觉心理的表现是指欣赏者对设计作品在视觉表现中产生的心理反映过程,其中包括图形、文字、色彩、肌理等视觉元素。研究中主要通过对艺术与视觉的关系、视觉心理表现等因素进行探究。

Counting moving persons in crowded scenes

The paper presents a method for estimating the number of moving people in a scene for video surveillance applications. The method performance has been characterized on the public database used for the PETS 2009 and 2010 international competitions; the proposed method has been compared, on the same database, with the PETS competitions participants. The system exhibits a high accuracy, and revealed to be so fast that it can be used in real time surveillance applications. The rationale of the method lies on the extraction of suited scale-invariant feature points and the successive selection among them of the moving ones, under the hypothesis that the latter are associated to moving people. The perspective distortions are taken into account by dividing the input frames into smaller horizontal zones, each having (approximately) the same perspective effects. Therefore, the evaluation of the number of people is separately carried out for each zone, and the results are summed up. The most important peculiarity of the proposed method is the availability of a simple training procedure using a brief video sequence that shows a person walking around in the scene; the procedure automatically evaluates all the parameters needed by the system, thus making the method particularly suited for end-user applications.     

三维高频风速时间序列波动特性研究

三维高频风速波动特性的研究对于全面、深入地揭示复杂风场流动及演化规律具有重要价值。采用多重分形消除趋势波动分析（MF—DFA）对高性能超声波风速传感器采集的三维风速时间序列进行波动特性分析。研究表明：水平风速和竖直风速均具有多重分形特性,但有着不同的波动结构,在竖直方向上的波动结构要更为复杂;水平方向风速信号的多重分形特性由长程相关性造成,与概率分布关系不大,而竖直方向上风速信号的多重分形特性与长程相关性和概率分布均存在一定的关联。     

Study on directional eye movements in non‐frontal face images for eye‐controlled interaction

Directional eye movements based eye‐controlled interaction focuses on interpreting the horizontal, vertical, and diagonal eye movements or their combinations as inputs to design user interfaces for people who suffer with severe mobility disabilities. In this paper, we take into consideration the inherent eye jitter and evaluate the accuracy of dynamic tracking of horizontal, vertical, diagonal, and rectangular eye movements prior to using them. We observe that the rectangular eye gesture composed of short horizontal and vertical eye movements has the best tracking accuracy in the presence of jitter. Finally, we present methods for identifying horizontal and vertical eye movements based on the trajectory of eye pupil centers from non‐frontal face images. We find that the methods are robust and effective within ±20°deflective azimuths of non‐frontal faces. This effectiveness is demonstrated by using the rectangular eye gesture as an interface to perform a painting task.     

Finding a Clear Path: Structuring Strategies for Visualization Sequences

Little is known about how people structure sets of visualizations to support sequential viewing. We contribute findings from several studies examining visualization sequencing and reception. In our first study, people made decisions between various possible structures as they ordered a set of related visualizations (consisting of either bar charts or thematic maps) into what they considered the clearest sequence for showing the data. We find that most people structure visualization sequences hierarchically: they create high level groupings based on shared data properties like time period, measure, level of aggregation, and spatial region, then order the views within these groupings. We also observe a tendency for certain types of similarities between views, like a common spatial region or aggregation level, to be seen as more appropriate categories for organizing views in a sequence than others, like a common time period or measure. In a second study, we find that viewers’ perceptions of the quality and intention of different sequences are largely consistent with the perceptions of the users who created them. The understanding of sequence preferences and perceptions that emerges from our studies has implications for the development of visualization authoring tools and sequence recommendations for guided analysis.

How should Fitts' Law be applied to human-computer interaction?

The paper challenges the notion that any Fitts' Law model can be applied generally to human-computer interaction, and proposes instead that applying Fitts' Law requires knowledge of the users' sequence of movements, direction of movement, and typical movement amplitudes as well as target sizes. Two experiments examined a text selection task with sequences of controlled movements (point-click and point-drag). For the point-click sequence, a Fitt's Law model that used the diagonal across the text object in the direction of pointing (rather than the horizontal extent of the text object) as the target size provided the best fit for the pointing time data, whereas for the point-drag sequence, a Fitts' Law model that used the vertical size of the text object as the target size gave the best fit. Dragging times were fitted well by Fitts' Law models that used either the vertical or horizontal size of the terminal character in the text object. Additional results of note were that pointing in the point-click sequence was consistently faster than in the point-drag sequence, and that pointing in either sequence was consistently faster than dragging. The discussion centres around the need to define task characteristics before applying Fitts' Law to an interface design or analysis, analyses of pointing and of dragging, and implications for interface design.     

A new technique for visual motion alarm

A new technique for motion detection and location is proposed and illustrated. It is intended for interactive visual surveillance systems. Absolute values of the differences between pairs of images belonging to a sequence taken by a still camera are computed. The absolute values are thresholded and projected onto horizontal, vertical, and two diagonal directions. Motion detection and location are derived from the backprojection image. The projections and the backprojection require two passes through a parallel pipeline processing engine (P³E). Examples are presented.
