“…Measures of cognitive load consist of the Paas mental effort scale [29] , [55] and custom questionnaires [7] , [56] . Several studies employed a dual-task methodology to measure cognitive load, whereby a user performs a secondary task in tandem with the primary task [29] , [46] .…”

Augmented Reality (AR) systems have been shown to positively affect mental workload and task performance across a broad range of application contexts. Despite the interest in mental workload and the increasing number of studies evaluating AR use, an attempt has yet to be made to identify the relationship between the effects of AR on mental workload and task performance. This paper seeks to address this gap in AR technology literature. With a better understanding how AR affects mental workload and task performance, researchers and developers can design more effective AR systems. 34 articles investigating the effects of the use of AR systems were selected for the review. A positive correlation was found between effects on mental workload and effects on task performance: if the effect on mental workload is positive, then the effects on task performance are more likely to be positive as well, and vice versa. Effectiveness of AR systems were shown to be influenced by the type of AR display device used, relevance and timeliness of content, information presentation, user characteristics and task characteristics. Additionally, the paper addresses the use of the concept of mental workload and limitations in current literature.

“…We offer another approach through AR that is visually richer and allows people to understand, interact with, and use data in its natural context based on findings in cognitive science. Despite the currently inconclusive evidence on the actual impact of using augmented reality on cognitive load [6,29,44], the proposed approach postulates that interactions with the Fused Twins may lower cognitive load by externalizing cognitive processes [37], logically organize the information [32], and enable more participation by a broad range of users (not only experts).…”

“…The externalization of cognitive processes into the augmented space allows for the reduction of perceptual and cognitive load when reasoning about data by removing the need for keeping the context in mind [37]. Using AR enables immersive analytics [9], has been shown to reduce task completion time in manufacturing [29,44], and can help to logically organize the information [32]. Viewed through a Fused Twins, data can be provided in a more natural context, allowing non-experts to engage more easily with the data in an augmented space.…”

a) Entering the augmented lobby in the Fused Twins. (b) Coming down the stairs into the augmented lobby.Fig. 1. The Fused Twins are used to augment the building's lobby with visualizations of sensors and agents through a HoloLens 2.Recent advances in Augmented Reality (AR), the Internet of Things (IoT), cloud computing, and Digital Twins transform the types, rates, and volume of information generated in buildings as well as the mediums through which they can be perceived by users. These advances push the standard approach of media architecture to embed screens in the built environment to its limits because screens lack the immersive capacity that newer media afford. To bridge this gap, we propose a novel AR approach to media architecture that uses a Digital Twin as a platform for structuring and accessing data from various sources, including IoT and simulations. Our technical contribution to media architecture is threefold. First, we extend the possibilities of media architecture beyond embedded screens to three dimensions by presenting a Digital Twin using AR with a head-mounted display. This approach results in a shared and consistent augmented experience across large architectural spaces. Second, we use the Digital Twin to integrate and visualize real physical sensor information. Third, we make artificial occupancy simulations accessible to everyday users by presenting them within their natural context in the Digital Twin. Observing the Digital Twin in situ of the Physical Twin also has applications beyond media architecture.Fusing the two twins using AR can reduce the cognitive load of users from consuming big and complex information sources and enhance their experience. We present two use cases of the proposed Fused Twins in a university building at ETH Zürich. In the first use case, we visualize a dense indoor sensor network (DISN) with 390 IoT sensors that collected data from March 2020 to May 2021. In the second use case, we immerse visitors in agent-based simulations to enable insights into the real and projected uses of space. This

“…The choice derives from the analysis of the information involved in the task that also depends on task complexity. This assembly task model was used as a theoretical basis in the study of Yang et al [ 34 ] that involved the joining subtask, too. They proposed as AR assistance, highlighting the target part with a black rectangle for the commissioning subtask, while for the joining subtask, a 3D model of the part to be assembled is displayed on the assembly zone.…”

“…This is just an example considering two types of visual assets, but we can generalize by saying that presenting a large amount of information quickly leads to a cluttered presentation, making it difficult for a viewer to gain insight into the data [ 33 ]. However, it is not clear from the literature how different designs of visual assets affect operator performance in achieving an industrial task [ 32 , 34 ]. Then, the following research question is formulated: “How does the information provided through AR visual assets affect user performance in task completion?”.…”
