Investigates how distance and interaction methods influence performance in virtual reality, suggesting design guidelines for improved user experience.
This study investigates how interaction methods and spatial distance affect user performance and experience in virtual reality (VR) tasks. We compared the Go-Go technique with ray-based Laser selection across eight target distances (0.67× to 4× arm length) in a memory task to identify distance ranges that minimize motor and cognitive demands and support working memory. Results with 41 participants revealed a trade-off: Go-Go enhanced embodiment, while Laser yielded higher efficiency and lower workload. This trade-off was distance-dependent: Go-Go performed best at 1.2×-1.4×, and Laser at 1.4×-2.2×. Our results offer practical design guidelines for adaptive, distance-aware VR systems that align performance and subjective experience.
