刘丽群[1] 李晨琛[2]
内容提要：用户对技术的选择和接受是媒体实践和数字媒介技术应用研究领域的重要议题。文章以智能手机密码系统为例，从可用性视角出发对媒体实践中的用户技术选择与接受进行了研究。通过控制实验和问卷调查，文章发现在效率、可记忆性、低出错率、主观满意度四个可用性维度上九宫格图形密码的表现均优于文字密码。在此基础上文章提出：可用性是影响用户技术接受的重要因素，在产品设计中应当占据重要位置，以可用性为基础的优秀设计理念可以引导技术的发展。这些观点为以用户为中心的新媒体技术产品设计提供了研究参照。

The Study on User Acceptance and Choice of Technology Based On Usability Theory:A Case Study of Smartphone Password System
Abstract:User acceptance and choice of technology is an important issue in the research filed of media practice and digital media technology.This paper did a case study of smartphone password system based on the usability theory.By controlling the experiment and questionnaires，this paper find out that Jiugongge graphical password's performance is better than text password in four dimensions of usability:efficiency，memorability，low error rates and subjective satisfaction.On this basis，the paper stated that usability is an important factor affecting user acceptance of technology，which means the product designers should occupy an important position to usabilitybased design.This view can be instructive for the development of new media technology product.
