Abstract:

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.
