It is acknowledged that multiple views technology improves designer’s work efficiency by filtering redundant information. However, the increased need of cooperative activities in product design process requires views incorporating Cooperative awareness information (CAI), content of which should be lean for understanding and sortable according to importance. To achieve this target, this paper proposes an Object-based cooperative awareness model (OBCWM) and corresponding multiple views system. Requirements of CAI in product design are firstly analyzed. Then OBCWM is proposed, which consists of a CPM (Core product model) based concept framework. By use of CPM, an algorithm to calculate awareness intensity is developed based on object-oriented method. To support the mechanism of OBCWM, a multiple views system is then designed with “flexible view”, content of which is adjustable according to awareness intensity between CAI objects. After introduction to the system, application on a case is presented, followed by the evaluation of this system. 相似文献

在分布式合作学习环境中,学生和老师需要一个共享的信息空间去与学习材料交互作用,并从中知晓合作者的存在及其活动.学生和老师还需要一些协同和通信手段去协调他们共同的活动.为此,提出了一种视觉化协同超媒体技术.它可以提供所需的共享信息空间.在此空间中,形象的超媒体对象既可以表示学习材料(学习内容),又可以表示学习过程(学习方法).这种协同超媒体集成了灵活的过程支持、通信渠道以及文件处理功能.因而,它可以支持学生(和老师)按一定的学习方法并通过文字或声音渠道去协调他们共同的学习活动.这种协同超媒体可以通过万维网(浏览器)访问.为了揭示这种技术的实用性,还给出了一个案例和一些用户体验. 相似文献

The field of computer supported cooperative work aims at providing information technology models, methods, and tools that assist individuals to cooperate. The presented paper is based on three main observations from literature. First, one of the problems in utilizing information technology for cooperation is to identify the relevance of information, called awareness. Second, research in computer supported cooperative work proposes the use of agent technologies to aid individuals to maintain their awareness. Third, literature lacks the formalized methods on how software agents can identify awareness. This paper addresses the problem of awareness identification. The main contribution of this paper is to propose and evaluate a formalized structure, called Policy-based Awareness Management (PAM). PAM extends the logic of general awareness in order to identify relevance of information. PAM formalizes existing policies into Directory Enabled Networks-next generation structure and uses them as a source for awareness identification. The formalism is demonstrated by applying PAM to the space shuttle Columbia disaster occurred in 2003. The paper also argues that efficacy and cost-efficiency of the logic of general awareness will be increased by PAM. This is evaluated by simulation of hypothetical scenarios as well as a case study. 相似文献

Team situation awareness (TSA) is a critical contributing factor in establishing collaborative relations among team members
involved in cooperative activity. Currently, however, there is still a lack of a clearly understandable and commonly agreeable
model of TSA. To resolve misunderstanding or conflict among team members or between a team and machines, our research aim
is to find out the underlying mechanism of TSA that reflects team cognitive process in a way consistent with team cooperative
activity, and to focus on how to achieve mutual understanding, and how to effectively incorporate human teams into a socio-technological
system. In this paper, we argue that earlier models of TSA, where TSA was discussed as the intersection of situation awareness
(SA) owned by individual team members, are inadequate for study of a sophisticated team reciprocal process. We suggest that
it is necessary for the definition of TSA to integrate the notion of individual SA (ISA) into cooperative team activity. In
particular, understanding of mutual awareness is an essential element in cooperative activity. We propose a new notion of
TSA, which is reducible to mutual beliefs as well as ISA at three levels. Further, we develop an operational TSA inference
method and discuss human competence and system-related factors that are required to build TSA. We then try to demonstrate
how TSA is actively constructed via inferencing practices. We also develop criteria to assess appropriateness of TSA from
two aspects: soundness and completeness of mutual beliefs. Comparison of evaluation results indicates that the notion of TSA
proposed in this work is more suitable to depict team cooperative activity than conventional ones. 相似文献
