Abstract
Dette studie undersøger, hvor godt virtuel virkelighed (VR) kan bruges til at lære praktiske procedurer, og om typen af controller har betydning for, hvor godt læring overføres til virkeligheden. Vi sammenlignede to inputenheder i et virtuelt læringsmiljø: en traditionel håndholdt Vive-controller, der giver vibrationsbaseret haptisk feedback, og SenseGlove DK1, en bærbar handske med et højere udførelsesniveau og kraftfeedback (følelse af modstand). Deltagerne lærte “forward-pipettering” – en almindelig laboratorieteknik til at måle små mængder væske. Med et mellemgruppe-design trænede én gruppe med Vive-controlleren og en anden med SenseGlove. Vi målte præstation på to måder: en virtuel øveopgave (VP), hvor deltagerne lærte handlingssekvensen i VR, og en realopgave (RP), hvor de skulle gentage proceduren. Gennemsnitspræstationer blev sammenlignet mellem grupperne. Under den virtuelle øvelse var resultaterne ens for de to controllere, men i den virkelige opgave klarede SenseGlove-gruppen sig signifikant bedre. Det tyder på, at håndbårne controllere med højere udførelsesniveau og kraftfeedback kan forbedre overførslen af procedurale færdigheder fra VR til virkelige situationer sammenlignet med traditionelle håndholdte controllere, der primært giver vibrotaktil feedback. Dog kunne ikke alle effekter isoleres i dette studie, og resultaterne afspejler den samlede virkning af inputsystemet og dets interaktioner. Desuden var stikprøven lille (N=20), så SenseGlove-fordelen kan være overvurderet; større studier er nødvendige for mere præcise estimater.
This study examines how well virtual reality (VR) can teach hands-on procedures and whether the type of controller affects how learning transfers to real-world performance. We compared two input devices in a virtual learning environment: a traditional handheld Vive Controller that provides vibration-based haptic feedback, and the SenseGlove DK1, a wearable glove with a higher level of execution and force feedback (a sense of resistance). Participants were taught “forward pipetting,” a common lab method for measuring small volumes of liquid. Using a between-subjects design, one group trained with the Vive Controller and another with the SenseGlove. We assessed performance in two ways: a virtual practice task (VP), in which participants learned the action sequence in VR, and a real-world performance task (RP), in which they attempted to reproduce the procedure. Average performances were compared between groups. The controllers produced similar results during virtual practice, but in the real-world task the SenseGlove group performed significantly better. This suggests that hand-worn controllers with a higher level of execution and force feedback can improve the transfer of procedural skills from VR to real settings compared with traditional handheld controllers that mainly provide vibrotactile feedback. However, not all effects could be isolated in this study, and the findings reflect the combined impact of the input system and its interactions. The sample was small (N=20), so the SenseGlove advantage may be overestimated; larger samples are needed for more precise estimates.
