Effects of Steering Strategies and Posture for 360° Object Selection in Virtual Reality
DescriptionWhile pointing and object selection in VR have been extensively studied for 2D interfaces, their behavior in 360° immersive environments remains a nontrivial issue. Much of the existing research limits targets to the initial field of view, which restricts ecological validity for omnidirectional applications. To address this gap, this study investigates how posture (standing vs. seated) and steering strategy (physical movement vs. controller) affect 360° object selection. A within-subject experiment was conducted with 36 participants selecting targets arranged in a full-spherical layout. Objective performance was measured via selection time, alongside subjective workload and perceived usability. Results showed that standing produced a significantly higher perceived workload than sitting. A significant interaction between posture and steering emerged: physical steering was faster and more usable when standing, but its effectiveness degraded when seated. Conversely, controller steering provided stable selection times across both postures and improved usability when seated. Spatial analysis also revealed that slower selections concentrated in the rear peripheral regions. Ultimately, physical rotation enhances efficiency in standing VR applications, whereas controllers improve usability and consistency in seated systems.
