【目的】降低用户获取Web生活服务信息的细节觉察成本和决策成本。【应用背景】Web环境下的生活服务信息,需要结合用户的情景,帮助用户快速获取信息。【方法】分析总结4种常见的用户需求,结合出行链理论和信息可视化技术中的Bertin编码原则,基于加权图的性质设计算法,进行Web生活服务信息可视化。【结果】以团购类Web生活服务信息为例,对该交互原型设计进行实现。【结论】验证Web生活服务信息可视化可以帮助用户快速建立心理定位。
[Purpose] To reduce the cost of knowing details and decision-making costs of acquiring Web service information for users. [Background] The life service information under the Web environment needs to combine with the user’s scenario to help the user to quickly obtain the information. 【Method】 Four common user needs were analyzed and summarized. Based on Bertin coding principle in travel chain theory and information visualization technology, the design algorithm based on the property of weighted graph was used to visualize the information of Web living services. 【Result】 Taking the life information of group purchase Web service as an example, the interactive prototype design was implemented. 【Conclusion】 Validating the visualization of Web living service information can help users quickly establish their psychological orientation.
