“…To overcome this limitation, the concept of Pervasive AR offers experiences that can be visualized continuously as users move through the environment. Such experiences are also characterized by being aware of and responsive to the user's context and pose [21,36,47].…”

Augmented Reality (AR) is a pillar of the transition to Industry 4.0 and smart manufacturing. It can facilitate training, maintenance, assembly, quality control, remote collaboration and other tasks. AR has the potential to revolutionize the way information is accessed, used and exchanged, extending user’s perception and improving their performance. This work proposes a Pervasive AR tool, created with partners from the industry sector, to support the training of logistics operators on industrial shop floors. A Human-Centered Design (HCD) methodology was used to identify operators difficulties, challenges, and define requirements. After initial meetings with stakeholders, two distinct methods were considered to configure and visualize AR content on the shop floor: Head-Mounted Display (HMD) and Handheld Device (HHD). A first (preliminary) user study with 26 participants was conducted to collect qualitative data regarding the use of AR in logistics, from individuals with different levels of expertise. The feedback obtained was used to improve the proposed AR application. A second user study was realized, in which 10 participants used different conditions to fulfill distinct logistics tasks: C1 — paper; C2 — HMD; C3 — HHD. Results emphasize the potential of Pervasive AR in the operators’ workspace, in particular for training of operators not familiar with the tasks. Condition C2 was preferred by all participants and considered more useful and efficient in supporting the operators activities on the shop floor.

“…Pervasive AR extends this concept through experiences that are continuous in space, being aware of and responsive to the user’s context and pose [ 12 , 13 ]. It has the potential to help AR evolve from an application with a unique purpose to a multi-purpose continuous experience that changes the way users interact with information and their surroundings.…”

“…The creation of these experiences poses several challenges [ 8 , 11 , 12 , 13 , 14 ], namely the time and technical expertise required to create such content, which are the main reasons preventing its widespread use; tracking of the user, i.e., understanding the user pose in relation to the environment; content management, i.e., making different types of digital content available (e.g., text, images, videos, 3D models, sound); adequate configuration of virtual content, i.e., configuring the experiences by choosing where augmented content is placed in the real world, as well as adequate mechanisms to display, filter, and select the relevant information at any given moment; uninterrupted display of information, i.e., making these continuous experiences available in order for them to be explored by the target audiences through adequate mechanisms; suitable interaction, i.e., providing usable interaction techniques to the devices being used, allowing easy-to-use authoring features; accessibility, which must be ensured for inexperienced users, while also providing experts with the full potential of the technology. Lastly, given the effects of the COVID-19 pandemic, which have abruptly upended normal work routines, it seems more relevant than ever to also consider remote features for these emerging experiences.…”

Comparing Desktop vs. Mobile Interaction for the Creation of Pervasive Augmented Reality Experiences

This paper presents an evaluation and comparison of interaction methods for the configuration and visualization of pervasive Augmented Reality (AR) experiences using two different platforms: desktop and mobile. AR experiences consist of the enhancement of real-world environments by superimposing additional layers of information, real-time interaction, and accurate 3D registration of virtual and real objects. Pervasive AR extends this concept through experiences that are continuous in space, being aware of and responsive to the user’s context and pose. Currently, the time and technical expertise required to create such applications are the main reasons preventing its widespread use. As such, authoring tools which facilitate the development and configuration of pervasive AR experiences have become progressively more relevant. Their operation often involves the navigation of the real-world scene and the use of the AR equipment itself to add the augmented information within the environment. The proposed experimental tool makes use of 3D scans from physical environments to provide a reconstructed digital replica of such spaces for a desktop-based method, and to enable positional tracking for a mobile-based one. While the desktop platform represents a non-immersive setting, the mobile one provides continuous AR in the physical environment. Both versions can be used to place virtual content and ultimately configure an AR experience. The authoring capabilities of the different platforms were compared by conducting a user study focused on evaluating their usability. Although the AR interface was generally considered more intuitive, the desktop platform shows promise in several aspects, such as remote configuration, lower required effort, and overall better scalability.

“…Prior studies had success employing AR to support HRI, integrating digital information in the robot workspace, simplifying the interaction, and removing the need for understanding the vast theory behind the robots [ 18 , 19 , 20 ]. Moreover, pervasive AR extends this concept through experiences that are continuous in space, being aware of and responsive to the user’s context and pose [ 21 , 22 , 23 ], changing the way users interact with their surroundings [ 24 ].…”

This work proposes an augmented reality serious game (ARSG) for supporting individuals with motor disabilities while controlling robotic wheelchairs. A racing track was used as the game narrative; this included restriction areas, static and dynamic virtual objects, as well as obstacles and signs. To experience the game, a prior configuration of the environment, made through a smartphone or a computer, was required. Furthermore, a visualization tool was developed to exhibit user performance while using the ARSG. Two user studies were conducted with 10 and 20 participants, respectively, to compare (1) how different devices enable configuring the ARSG, and (2) different tracking capabilities, i.e., methods used to place virtual content on the real-world environment while the user interacts with the game and controls the wheelchair in the physical space: C1—motion tracking using cloud anchors; C2—offline motion tracking. Results suggest that configuring the environment with the computer is more efficient and accurate, in contrast to the smartphone, which is characterized as more engaging. In addition, condition C1 stood out as more accurate and robust, while condition C2 appeared to be easier to use.
