从产品语意认知角度看情感化设计

产品情感化的设计趋势已是不争的事实,但是综观对于语意学的研究大都将目光集中在产品语意的表达之上,对于语意的认知过程的研究却是少之又少.通过一些例证提出这一问题,分析了产品语意认知的重要性,指出情感化是一个认知的过程,而不单单是产品形态与意义的一一对应关系,并且产品符号学、语意学的研究要从符号中来,更要跳出符号之外.

基于区间特征根-改进二元语义的储罐区应急救援能力评价

为了对储罐区的应急救援能力进行有效评价,识别工艺流程中的薄弱环节,提高储罐区对突发事件的应对能力,按照事故管理周期,将预防能力、准备能力、响应能力和恢复能力等纳入储罐区应急救援能力评价体系。采用区间特征根法确定指标权重,并利用改进的二元语义模型对储罐区的应急能力进行计算和评价。通过实例验证,该模型的评估结果与实际情况基本相符,能够快速、真实地反映储罐区的应急能力水平,可为管理者采取防控措施和应急管理提供理论依据。

Data driven webpage color design

This paper presents a design framework for automatic webpage coloring regarding several fundamental design objectives: proper visual contrasts, multi-color compatibility and semantic associations. The objective functions are formulated with data-driven probabilistic models: the Color Contrast model concerning visual saliencies is trained on 52,000 basic components parsed from 500 popular webpages. Color Compatibility and Semantics are modeled from a dataset of manually tagged and rated color schemes from Adobe Kuler. To incorporate the multi-objectives in optimization, the framework adopts a lexicographic strategy, which determines the best choices by optimizing the objectives one by one in a user specified sequence. We demonstrate the effectiveness of the models and the flexibility of the framework in two typical web color design scenarios: fine tuning a colored page and recoloring a page with a specified palette. Independent perception experiments verify that the system-generated designs are preferable to those generated by nonprofessionals.     

An approach to automatic adaptation of assembly models

Adaptation plays a fundamental role in case-based design. However, after decades of efforts, automatic adaptation is still an open issue. In works of case-based design, a designer usually chooses a start-up product model (a candidate model) of moderate complexity based on a query model possessing primary new design requirements (kinematic semantics and geometry), then achieves the target design by adapting the candidate model according to the new design requirements and human interventions are often indispensable. To smartly adapt the candidate model to fit the new design requirements, a novel approach to automatic adaptation of assembly models is proposed in this paper. First, in order to effectively identify the corresponding links and interfaces between two non-preregistered assembly models as relevant elements, an attributed kinematic graph is put forward and adopted. Second, based on the attributed kinematic graph, the kinematic semantics of the candidate model is automatically adapted to that of the query model. Third, through performing interface layout transferring, the geometry of the candidate model is automatically adapted to that of the query model based on the corresponding links and interfaces. A prototype system is also implemented to verify the effectiveness of the proposed approach.
