移动终端三维用户界面的可用性评估

本文针对移动终端的三维用户界面进行了可用性评估.从系统性能,任务绩效和用户偏好三个方面进行了全面的考察.物体选取是三维用户界面中基础的交互任务,我们结合实验数据分析,基于二维环境下的指点模型,提出并验证了一个新的基于三维用户界面的通用性能模型.同时通过用户调查和问卷分析,说明了三维用户界面在移动终端上具有较高的用户偏好.

An Usability Testing for the 3D User Interface on Mobile Terminals

This paper gives a usability testing for the 3D user interface on mobile terminals.The test is based on the investigation on system performance,task performance and the user preference.We analyze the data collected from user performance in pointing in the 3D user interface which is the most fundamental interaction task,and building upon the results in the modeling of pointing in 2D environment,we propose and validate a new general performance model that describes pointing at targets in the 3D user interface.We also prove that the 3D user interface on mobile terminals has a high user preference using user questionnaires survey.
