交互设计提升理财类APP可用性研究

目的通过研究提出交互设计原则,提升理财类APP的交互设计水平,进而提升其可用性。方法归纳理财类APP可用性目标,通过用户访谈与问卷调查的方式,探索用户行为习惯与使用偏好,提出基于可用性的理财类APP交互设计原则。对某财富APP进行再设计,使其遵循交互设计原则。对改良前后的设计进行可用性测试,被测试者分别使用改良前后的设计原型完成4组任务,统计并对比用户完成任务的操作时间、成功率、用户满意度,判断改良后的设计在可用性方面是否有所提升。结论理财类APP可通过包括符合用户心智模型的呈现形式、合理的信息搜寻路径与信息展示方式、确保可学习性、确保安全性、提升社交体验的方式提升交互设计,有效提升应用的可用性。

Enhancing Usability of Financial APP through Interaction Design

The work aims to propose the interaction design principle through study to improve the interaction design level of financial APP,thus enhancing its usability.The purpose of financial APP usability was summarized,and user's behavior habits and preferences were explored through user interviews and questionnaires.Finally,the interaction design principle of financial APP based on usability is put forward.A fortune APP was redesigned to follow the interaction design principle.For the usability test,the tested users completed four groups of tasks with the design prototype and the optimized design.The time,success rate and user satisfaction of usability test were counted and compared to determine whether the optimized design was improved in usability.Financial APP can enhance the interaction design by the following ways,including the form of presentation that meet user’s mental models,reasonable information search paths and information presentation modes,ensuring learnability and safety and enhancing social experience,thus effectively improving the usability of the application.
