Surprisingly, limited research has paid attention to the cognitive load of operators in their collaborative tasks, especially via VR interfaces. Once task demands become complex, many researchers focus on optimizing the design of the interaction interfaces to reduce the cognitive load on the operator. In this paper, we propose a new collaborative VR system with edge enhancement to support two teleoperators working in the VR environment to remote control an uncrewed ground vehicle. We use a compared experiment to evaluate the collaborative VR systems, focusing on the time spent on tasks and the total number of operations. Our results show that the total number of processes and the cognitive load during operations were significantly lower in the two-person group than in the single-person group. Our study sheds light on designing VR systems to support collaborative work with respect to the flow of work of teleoperators instead of simply optimizing the design outcomes.","PeriodicalId":54628,"journal":{"name":"Personal and Ubiquitous Computing","volume":"23 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140928167","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Prevention of unauthorized access and defining access domains for legitimate users are crucial. Attribute-Based Access Control System (ABACS) techniques play a vital role in defining boundaries in a multi-agent environment. However, adopting traditional ABAC in IoT-based resource-constrained networks is not feasible. This research analyzes the effects of attributes as key performance metrics, including execution time, memory overhead, and computational complexities. To address these challenges, this research proposes a Physical-Social Attributes Access Control Policy (PS-ABACS) framework that secures Multiparty Computation (SMC), symmetric encryption, and randomization-based access control methods. PS-ABASC introduces a lightweight two-party set intersection technique to generate an access policy. The analysis shows that the proposed technique is efficient in computing access policy and session key generation, and less number of attributes based on randomness characteristics is appropriate for resource-constrained networks. Moreover, it demonstrates advancements by reducing memory usage up to 0.048 KB for 60 attributes. The framework generates session keys proficiently, encrypts data, and minimizes computational expenses through a randomized attribute vector. In terms of communication overhead, the framework surpasses expectations by supporting up to 100 attributes, resulting in a reduction of transmission costs to 1120 bits. Overall, this framework improves security, reduces resource consumption, and enhances data exchange efficiency in IoT ecosystems.","PeriodicalId":54628,"journal":{"name":"Personal and Ubiquitous Computing","volume":"19 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140886247","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It provides users with a visual overview of multivariate data and the possibility to interactively explore it. While pattern recognition is a strength of the human visual system, it is also a strength of the auditory system. Inspired by the integration of the visual and auditory perception in everyday life, we introduce an audio-visual analytics design named Parallel Chords combining both visual and auditory displays. Parallel Chords lets users explore multivariate data using both visualization and sonification through the interaction with the axes of a parallel coordinates plot. To illustrate the potential of the design, we present (1) prototypical data patterns where the sonification helps with the identification of correlations, clusters, and outliers, (2) a usage scenario showing the sonification of data from non-adjacent axes, and (3) a controlled experiment on the sensitivity thresholds of participants when distinguishing the strength of correlations. During this controlled experiment, 35 participants used three different display types, the visualization, the sonification, and the combination of these, to identify the strongest out of three correlations. The results show that all three display types enabled the participants to identify the strongest correlation — with visualization resulting in the best sensitivity. The sonification resulted in sensitivities that were independent from the type of displayed correlation, and the combination resulted in increased enjoyability during usage.","PeriodicalId":54628,"journal":{"name":"Personal and Ubiquitous Computing","volume":"14 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140886497","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
