摘要
眩晕问题是影响虚拟现实体验的一个重要因素。以动感单车的虚拟骑行为例,从侧倾体感反馈的角度,提出了降低用户眩晕感的设计方案,并对其进行了用户体验度量。首先,设计了可能的3种骑行姿态的反馈方式,分别是基于用户自身侧倾的体感反馈方式(IR模式)、基于用户转弯角度的体感反馈方式(PR模式)和无反馈方式(NR模式)。然后,对3种反馈方式进行了用户体验度量。研究表明,IR模式不适用于虚拟骑行;PR模式与NR模式相比,除了能降低用户在转弯过程中的眩晕感外,还提高了用户的临场感、系统的易学性及易用性。
Dizziness in virtual reality is an important factor that affects users’experience.This research takes the immersive virtual riding as an example to propose a solution to lower dizziness as well as to measure the users’experience from the perspective of heeling feedback.Firstly,three patterns of heeling feedbacks responding to relative riding positions are put forward and applied in virtual cycling,including the pattern based on active rolls(IR mode),the pattern based on angles of turns(PR mode)and the pattern without feedback(NR mode).Then,the users’experience when riding under these three patterns is measured.The results show that IR mode is not suitable for virtual cycling.Moreover,compared with NR mode,PR mode not only reduces dizziness in the process of turning but also improves the users’sense of being present on site,as well as the cycling system’s learnability and usability.
