Abstract [en]

In this study, we investigate a VR simulator of a forestrycrane used for loading logs onto a truck, mainly looking at Qualityof Experience (QoE) aspects that may be relevant for taskcompletion, but also whether there are any discomfort relatedsymptoms experienced during task execution. The QoE test hasbeen designed to capture both the general subjective experience ofusing the simulator and to study task completion rate. Moreover, aspecific focus has been to study the effects of latency on thesubjective experience, with regards both to delays in the cranecontrol interface as well as lag in the visual scene rendering in thehead mounted display (HMD). Two larger formal subjectivestudies have been performed: one with the VR-system as it is andone where we have added controlled delay to the display updateand to the joystick signals. The baseline study shows that mostpeople are more or less happy with the VR-system and that it doesnot have strong effects on any symptoms as listed in the SSQ. In thedelay study we found significant effects on Comfort Quality andImmersion Quality for higher Display delay (30 ms), but verysmall impact of joystick delay. Furthermore, the Display delay hadstrong influence on the symptoms in the SSQ, as well as causingtest subjects to decide not to continue with the completeexperiments, and this was also found to be connected to the longerDisplay delays (≥ 20 ms).
