Augmented and Virtual Reality Evolution and Future Tendency

2020

Augmented reality and virtual reality technologies are increasing in popularity. Augmented reality has thrived to date mainly on mobile applications, with games like Pokémon Go or the new Google Maps utility as some of its ambassadors. On the other hand, virtual reality has been popularized mainly thanks to the videogame industry and cheaper devices. However, what was initially a failure in the industrial field is resurfacing in recent years thanks to the technological improvements in devices and processing hardware. In this work, an in-depth study of the different fields in which augmented and virtual reality have been used has been carried out. This study focuses on conducting a thorough scoping review focused on these new technologies, where the evolution of each of them during the last years in the most important categories and in the countries most involved in these technologies will be analyzed. Finally, we will analyze the future trend of these technologies and the areas in which it is necessary to investigate to further integrate these technologies into society.

“…Tait et al also indicated that the provision of independent viewpoints led to faster task completion in remote collaboration [4]. By using a head-mounted display (HMD) and tracking system, users can freely move to set their viewpoint independently in such VR/AR-based systems [5,6].…”

“…The environments of local users were captured and reconstructed in a virtual environment, which was shown in the HMDs of remote users. In addition, the remote user's movements were captured and presented as an avatar to local users [5,20,21]. In contrast to these systems using HMD, Pejsa et al used projected augmented reality techniques instead of HMDs to develop a life-sized co-present environment including the complete body of a remote participant for remote communication [22].…”

“…Usability is the degree of ease with which a system can be used to achieve the required goals. It includes several aspects, such as learnability and ease-of-use, and has been widely used to evaluate remote collaboration systems [4,5,11,19,20,38,39]. The workload is the amount of effort a user must spend to accomplish a task.…”

“…The workload is the amount of effort a user must spend to accomplish a task. No standard method to evaluate the workload in a task performed using a remote collaboration system exists; some researchers have employed a self-designed questionnaire [5], although most studies have used an existing questionnaire, such as the NASA Task Load Index (NASA-TLX) [29,30,[40][41][42], SMEQ [20,39], or SEQ [20]. The performance is a fundamental aspect in evaluating a remote instruction system.…”

In manufacturing, augmented reality (AR)-based remote instruction systems, which enable workers to receive instructions from an avatar, are widely used. In this study, we developed such a system and investigated the effect of the body representation level of the avatar on the quality of AR-based remote instruction. Drawing on the avatar designs of previous works, three different avatar designs (“Hand only”, “Hand + Arm”, and “Body”), representing three body representation levels, were created. In the experiment with a within-participant design, the avatar pointed at blocks sequentially and participants touched each block as soon as they identified it. The results of the experiment indicate that an AR-based remote instruction system with a “Body” avatar exhibits higher usability and can enable the participants to have a lower workload and higher efficiency.

This paper studies users' learning perception in a virtual titration experiment with differentiated instruction. We develop a virtual reality chemistry lab and use leap motion to detect users' hand gestures for operations. Users wear a head‐mounted display and use their bare hands to interact with virtual objects to perform a titration experiment. Our system implements a complete titration process and provides assistance tools for learning and operating virtual items. We report the essential ideas for building the system. We applied differentiated instruction to study the learning effectiveness of users under different learning intensities. Two groups of students with and without chemistry background participated in a user study. Our results indicated that the virtual reality chemistry lab could enhance and promote users' learning confidence under suitable learning intensities.
