Abstract

This study examines how presenting data visualizations in augmented reality (AR) affects user experience and mental effort. We use the User Experience Questionnaire (UEQ) to capture users’ perceptions and NASA-TLX, a widely used workload rating scale, to assess perceived effort. These are related to task performance metrics, including time on task, task success rate, and task duration. To add a physiological perspective, we record blood volume pulse (BVP) and electrodermal activity (EDA). Together, these measures are used to estimate cognitive load, especially the portion caused by the way information is presented rather than by the task itself (extraneous cognitive load). We developed a dynamic, fully AR-integrated data visualization application (n = 29) and compared it with a static, limited AR version (n = 29) to see how the AR medium influences experience and load. The findings are statistically significant: user experience improves, and extraneous cognitive load increases, when the fully integrated AR application is compared with the limited one.

Dette studie undersøger, hvordan datavisualisering i udvidet virkelighed (Augmented Reality, AR) påvirker brugeroplevelse og mental belastning. Vi anvender User Experience Questionnaire (UEQ) til at måle brugernes vurdering af oplevelsen og NASA-TLX, en udbredt skala for arbejdsbelastning, til at vurdere oplevet indsats. Disse vurderinger sættes i relation til mål for opgavepræstation, herunder tid på opgave, opgavesuccesrate og opgavelængde. For at belyse den fysiologiske side måler vi blodvolumepuls (BVP) og elektrodermal aktivitet (EDA). Tilsammen bruges disse mål til at estimere kognitiv belastning, herunder den del, der skyldes præsentationsformen snarere end opgaven (extraneous kognitiv belastning). Vi udviklede en dynamisk, fuldt AR-integreret datavisualiseringsapplikation (n = 29) og sammenlignede den med en statisk, begrænset AR-version (n = 29) for at se, hvordan AR-mediet påvirker oplevelse og belastning. Resultaterne er statistisk signifikante og viser, at brugeroplevelsen forbedres, men at extraneous kognitiv belastning øges, når den fuldt integrerede AR-løsning sammenlignes med den begrænsede.
