一种基于眼动追踪的产品用户需求获取方法

为提高用户需求获取的准确性,提出一种基于眼动追踪的产品设计用户需求获取方法。通过设计眼动实验,分析人眼对不同风格产品形态观察时的运动轨迹并得出实验数据。从心理学角度研究眼动实验参数与用户消费心理的联系,选出首次注视持续时间、首次注视时间、注视总次数、平均瞳孔直径四项参数构建用户需求获取指标评判体系。使用综合赋权法确定参数的权重,加权各样本并比较,最终确定用户需求。以手机设计的用户需求获取为案例对该方法进行了验证。

融合用户满意度的产品需求配置方法研究

为合理地确定用户需求偏好及其优先程度以适应大规模定制生产模式,最大限度 提升用户满意度,提出一种改进的产品用户需求配置方法。将模糊聚类分析方法融入Kano 模 型中对用户需求进行归属分类,根据用户需求对满意度提升的贡献程度进行筛选,计算需求 满意度及重要度评价因子,建立产品用户需求递阶层次结构模型。在模糊层次分析法(FAHP) 中通过采用模糊最优最劣法(FBWM)构造一致性三角模糊数互补判断矩阵,引入可能度概念实 现去模糊化,得到用户需求初始权重,并将需求评价因子作为初始权重的修正因子,将修正 后的权重进行归一化处理,得到用户需求综合权重,以此为依据实现产品需求配置。以某企 业眼镜产品设计开发为例,验证了该方法的有效性,为眼镜及其他产品设计开发提供了用户 需求配置策略。     

产品经理和用户需求

最近,同事跟我讲了一个笑话：长沙21岁大学生和女友在网吧通宵上网时,女友手机被偷。为帮女友找回手机,小李在网吧兼职做夜班网管,蹲守了13个通宵后,小李终于等到窃贼,将其抓获。女朋友知道后十分感动但是她已经跟了送她爱疯5的学长。他说：“这是一个产品经理和用户需求的故事。”

PDM中面向角色用户管理的研究

PDM中直接将权限分配给用户的用户管理方法已经被淘汰,目前大多数采用面向对象技术的用户管理技术,它主要由用户、权限和角色三个对象构成,将权限赋给角色,再将角色分配给用户。这种方法显然比前一种优越许多,它不但节省了时间、而且还方便了操作,用户不需要花大量的时间重复分     

基于用户需求的产品深度个性化定制

为解决现有产品个性化定制中用户需求分析复杂、需求契合度低与用户参与度不 足的问题,提出一种基于用户需求的产品深度个性化定制方法。通过结合用户个性需求表达模 型与质量功能展开(QFD)将用户需求映射为定制需求,运用实例检索与匹配进行产品配置求解。 用户通过可视界面对定制方案进行实时反馈与调整,并结合变型设计加深产品个性化定制程度, 最后通过优度评价将最优方案提供给用户,实现用户高参与度、高满意度的定制。以披肩定制 为例,验证该方法的可行性,为产品深度个性化定制提供了一种有效方法。     

Effective user involvement in product development by improving the analysis of user needs

User involvement has been shown to be beneficial in the development of useful and usable systems. The trend of software development becoming a product-oriented activity creates challenges to user involvement. Field studies appear a promising approach, but the analysis of the gathered user needs has been shown to be demanding. This study presents, on the basis of seven case studies, an early user-involvement process showing how user needs can be analysed and how the input to product development can be identified. In addition, the process is evaluated in two industrial cases with interviews and a questionnaire. The results show that the process supports effective early user involvement; the resulted requirements were evaluated as being more successful and their quality as better than average in a company. However, the case studies show that user involvement not only provides useful information about users' needs but also increases the understanding of users' values.     

Present-ing the user: constructing the persona

Abstract

During the last few years personas has become an established design technique within the IT-design field. Using personas has proven itself as a valuable approach for designers to switch between a developer's perspective and a user's perspectivein the design process. The technique is claimed to help designers in keeping a clear focus and shaping a consistent user-interface by making ‘the user’ present in the design work. In this paper we report on a number of projects where we have elaborated on the persona approach for collaborative design. With the goalof creating ‘user presence’ in the design process, we have developed an approach building on a combination of ethnographic exploration, participatory inquiry, and collaborative design. This paper carries two interrelated points: the grounding of personasin existing practice; and the notion that ‘the user’ is created as an ongoing process throughout the design work.     

Configurable product views based on geometry user requirements

This paper describes an approach at Volvo Truck Corporation where geometry users' requirements are utilised to define configurable product views. The paper is derived from a research framework on geometry management. The objective of the research framework is to improve reuse of geometry by providing relevant geometry-based product information, so-called geometric product views, through application of configuration management. In order to provide relevant product views, specific fundamental product information must exist. This type of information will vary depending on the different types of product views. Several examples on product view are presented. The product views are realised by a developed configuration management system, an example of a configured product view is presented as proof of concept. The configuration management system is currently under industrial implementation.     

Constructing user requirements: a social process for a social context

We discuss our approach to constructing user requirements whereby users build requirements models themselves. The approach, termed user-led requirements construction (ULRC), is a social process that addresses a major problem: the user-developer culture gap. An important feature of the approach is that we have conducted, with users, an interpretivist empirical evaluation study of its constituent event flow diagram (EFD) modelling method and associated training. The ULRC has also been used in a live environment. The results are that users regard the EFD as effective for the requirements process, the EFD may be used for further studies to deepen our knowledge of the requirements process and the results contribute towards a set of public results for general evaluation and improvement.     

A novel approach for capturing and evaluating dynamic consumer requirements in open design

In the product design, understanding consumer requirements (CRs) is essential due to the fact that it influences the success of the product. Currently, it has been recognized that consumer involvement in an open design (OD) environment is an effective way to reduce the gap between what is required by consumers and what companies can provide. In the process of OD, the initial CRs may shift as the consumers can influence each other, and it is a challenge to capture and evaluate dynamic CRs in OD. In this study, the dynamic relationship between consumers who participate in OD is discussed based on Nash equilibrium. Corresponding to the dynamic relationship, a novel approach is proposed to explore the crucial CRs from consumers’ perspective. Initially, the platform of OD is constructed on the Internet to collect the CRs and its evaluations. Thereafter, a similarity-based filtering method (SFM) is presented to filter out the most differentiated evaluations. Furthermore, to get the weight of the CR evaluated by consumers, an improved fuzzy Delphi method is introduced. Meanwhile, to solve the problem of excessive number of CRs, a dual-index evaluation method is put forward to control the opening degree of OD. Finally, to demonstrate the applicability of the suggested approach, a product of smartphone is examined as a case study. The results confirm that the proposed approach is appropriate for capturing and evaluating dynamic CRs in OD.
