Motion parallax from head movement enhances stereoscopic displays by improving presence and decreasing visual fatigue
Section snippets
Related work
In this section, we briefly review previous studies of FTVR, CAVE, and measurement of visual fatigue.
Experimental methods
Our objective was to determine the extent to which motion parallax enhances user experience beyond that obtainable with a stereopsis-only display. We focus on two properties of a FTVR system that affect a wide array of activities, rather than the users’ performance of a specific task. The first property is the level of presence that the system provides for the user, because increased presence will indicate increased naturalness of interaction in tasks requiring 3D awareness such as 3D modeling
Results
This section presents results of the experiment. We begin with results on visual fatigue, which are followed by results on level of presence, view mode comparisons, head movement, and participants’ feedback.
Discussion
In this section, we discuss our observations about users’ behavior, provide some interpretation of the effects, and make some recommendations for future FTVR projects.
Conclusion
This paper describes a thorough study of the importance of motion parallax cues for the user’s sense of presence and fatigue in FTVR interfaces. In the experiment, we focus on determining the extent to which motion parallax enhances stereopsis. We use the Simulation Sickness Questionnaire (SSQ) to measure visual fatigue and the Presence Questionnaire (PQ) to measure the level of presence experienced by the user. The activity in this experiment is designed to require an extensive amount of time
