A data mining technique for discovering distinct patterns of hand signs: implications in user training and computer interface design

Hand signs are considered as one of the important ways to enter information into computers for certain tasks. Computers receive sensor data of hand signs for recognition. When using hand signs as computer inputs, we need to (1) train computer users in the sign language so that their hand signs can be easily recognized by computers, and (2) design the computer interface to avoid the use of confusing signs for improving user input performance and user satisfaction. For user training and computer interface design, it is important to have a knowledge of which signs can be easily recognized by computers and which signs are not distinguishable by computers. This paper presents a data mining technique to discover distinct patterns of hand signs from sensor data. Based on these patterns, we derive a group of indistinguishable signs by computers. Such information can in turn assist in user training and computer interface design.

工业设计中的抗疲劳研究

西方工业革命迫使产品使用者与设计者由同一化分离,形成了崭新的社会分工格局。在这样的社会背景下,使用期望与产品设计间的断层往往会引发设计缺陷。设计缺陷将会引起使用者的不适与疲劳,而疲劳积累则是造成事故的主要原因之一。因此在设计多元化的今天,我们依然不可忽视"适用于使用者"这一设计的根本出发点。文章通过对生理疲劳与心理疲劳的产生因素、作用机理等方面进行分析,提出了改进设计以缓解疲劳的措施。     

HCI and Society: Towards a Typology of Universal Design Principles

The task of this article is to focus on aspects of design from a theoretical perspective that works out a general framework of techno-social design that is grounded in the notion of the participatory, cooperative, sustainable information society. The approach is normative in that it is based on the judgment that not just any information society is needed, but one that has specific qualities that this article tries to identify. Methodologically, the article works out a conceptual framework that synthesizes general social theory and human–computer interaction. Design is seen as a social process that shapes society and techno-social systems. First, a model of society that is based on the dialectical interaction of economic, political, and cultural subsystems is introduced. Then, the notion of the the participatory, cooperative, sustainable information society is introduced. This theoretical definition is then used for classifying design principles of techno-social information systems from a social theory perspective.

Design evaluation and modification of mechanical systems in virtual environments

Design is one of the most important stages in the manufacturing cycle and influences all the subsequent stages of product development. In the context of today’s iterative design methodology, the modification of any design is a process involving many evaluations and improvements to the solutions chosen in earlier stages. For this purpose, in the most recent decade, 3D computer simulations have become common tools used within industry. Whilst virtual reality (VR) technology is seen as the interaction technology of the future, much of the current research in this area is carried out to explore the potential benefits and added value brought by the integration of this into standard software technologies currently used at various stages in manufacturing life cycle. A lot of attention has been given to exploring the usability and benefits of interactive VR for assembly planning, knowledge elicitation and design and simulation. However, little research has focussed on the analytical aspects of the design process, for example in the use of VR as an interface for simulation software in finite element methods and multi-body systems. This paper introduces research focussing on applications of virtual environments (VEs) for interactive design evaluation and modification adapted and used with standard simulation software. The use of such interactive visualisation offers the engineer more realistic real-time representations of the design and advanced facilities to interact with the model during the design process. While design evaluation is based mainly on visualisation; design modification requires interactive changes of the model during the simulation, and the interfaces described here highlights such applications. In this work, two software prototypes have been developed using VR technology. First, a software tool called design evaluation in virtual environments is presented together with an application in civil engineering to illustrate the mode of operation and added value of the use of an interactive visualisation environment. Linking the simulation software with the VE provides real time bi-directional communication of graphical information which can be successfully achieved even within the limits of current computer technology. The tool includes a suite of software modules and a user interface to facilitate the link between the simulation results and the VE. The second tool facilitates the design modification in virtual environments system by providing real time dynamic simulation. Two dynamic approaches are investigated in order to study the real time simulation issues in the context of design modification and system performance: the classic approach based on rigid interconnected bodies, and a new and novel approach developed by the authors based on particles dynamics. Both implementations have been tested and compared on a mechanism application under the same computing conditions. The research applications presented demonstrate the practicality, flexibility and versatility of the visualisation in virtual environment in design evaluation and modification. However, the computer efficiency whilst carrying out real time dynamic simulation is limiting the range of applications to models of moderate size; however, this is an improvement on previous similar applications.

关于传统文化元素在当代展示设计中传承与运用的思考

展会究其实质是传播,传播关乎受众,因而观众的思维意识是不得不考虑的因素;设计则关乎创意,是创意的视觉再现,创意源自设计师自身的眼界与素养,归根结底是一种文化的积累与创新。最终,创意将取决于受众(观众)的理解与认知。而受众的审美意识与精神素养总是与其所受的文化熏陶、历史环境、社会习惯相统一。因而,在展示设计中融入具有本土特色的传统视觉元素,形成具有中国传统文化内涵的展台形象,有助于迎合参观者的心理需求,取得受众在文化上的认同,更好地实现设计诉求。

Shoppers and Tailors: Participative Practices in Small Australian Design Companies

The focus of this paper is the relations between the work practices and technology needs of small Australian design companies and the discourses of Participatory Design. Because these companies use off-the-shelf technology, these relations are shaped not just by factors specific to company size, but also by the geographic and cultural separation between the situation of use and the situation of design. User participation focuses on shopping decisions, and the fitting of purchased technology to the local work situation. While many aspects of job design can be extremely flexible within small companies, participation in the design of computer systems is bounded by the available products and the options for continuing design-in-use that are embedded within them. The paper starts from the recognition that participative practices are important in the design of any job. From this perspective the discourses of Participatory Design that are relevant to small companies are those that support the participative design of work, irrespective of the national or industrial location of the people involved.     

A part affordance-based approach for capturing detailed design knowledge

Design knowledge reuse is widely accepted as an effective strategy for designers to develop robust artifacts with less time and lower cost. However, there has been very little research on how to help designers capture detailed design knowledge for reuse. As a result, most detailed design knowledge still has to remain in designers’ memories as tacit knowledge, which can easily get lost due to oblivion or the mobility of designers. Therefore, this paper attempts to develop a part affordance-based approach for externalizing and capturing detailed design knowledge for effective reuse. It first introduces a part model for representing the detailed design-related information. Based on the relational theory for design, the concept, part affordance, is then employed to help designers externalize and capture various lifecycle factors that are implicit in a detailed design. Based on the affordance constraint axiom, a systematic approach is then proposed for deriving tacit design knowledge from captured part affordances through the analysis of extreme working situations. The proposed approach has been implemented as the Design Knowledge-Capturing System (DKCS). A fixture design case has been employed to illustrate the proposed approach.
