Contents I. Introduction
The convergence of cognitive informatics and communication has paved the way for innovative advancements in human-computer interactions and virtual reality (VR) experiences [1], [2]. The emergence of 3D VR holds the promise of a transformative impact, empowering users to engage with and manipulate both 2D and 3D content within an immersive digital environment [3]–[8]. The existing body of scientific literature has provided consistent evidence regarding the potential advantages of 3D VR. It suggests that users may be able to access a wide range of information within notably shorter timeframes [9] and participate in remote events without being limited by geographical or temporal constraints [10]. User efficiency studies are gaining ground in the development of digital environments. A recent study [11] defined objective metrics for user efficiency, based on which the number and quality of operations performed in each digital environment were analyzed in terms of cognitive load. It was observed that within a 3D immersive virtual environment, there was a 31 percent reduction in the number of elementary operations required to complete task workflows compared to a 2D interface. Additionally, the cost associated with accessing information was found to be 54 percent lower. Moreover, 3D VR appears to offer potential benefits for intricate cognitive tasks, including the ability to discern relationships, gain insights, apply knowledge, and engage in analytical reasoning [12]–[14].
