Virtual Reality (VR) is a technology well equipped to enhance learning processes. The development of Learning Activities with Virtual Reality (LAVR), however, remains a complex process. This makes it a somewhat costly process, the full cost of which can be reduced by using a set of tools (framework) for implementing LAVR, involving an educational model with which to guide the developer. In this paper, we review scientific articles that focus on learning processes that use immersive technologies, seeking to identify frameworks and guidelines for the creation of LAVR. To do this, a systematic mapping of the scientific production in ScienceDirect was carried out, observing those studies from 2015 onward that involved topics including virtual reality, learning activities, Bloom taxonomy, and the state of the practice in which they are found. The results show that no studies are to be found in the literature on frameworks, guidelines, or recommendations either for the creation of LAVR or for the production of frameworks that facilitate this process using the Bloom taxonomy. However, studies can be found that guide the creation of LAVR, and these could be used as the basis for creating a framework. Based on the review, it could be concluded that VR favors learning processes at the various levels of education in a range of areas but that there is a paucity of directives able to facilitate the creation, adaptation, and incorporation of LAVR. This, therefore, constitutes a field of interest that merits further research.

“…A task description or also known as the detailed diagram reflects on the overall flow of the task analysis of maintenance workers. Task analysis can be a powerful tool to give insight in task execution and to identify potential improvements in human-machine interaction 11 . In this study, the task analysis is performed in three phases, which are based on an HTA task decomposition with four levels of detail: task level, subtask level, within subtask levels.…”

Rail maintenance routines are necessary to enable the all rail operations to achieve its aim in maintaining a safe and efficient operation. The maintenance tasks expose the workers to vibration and noise, as they handle specialized machineries and heavy self-propelled vehicles. Exposure of noise above the permissible exposure limit and over the daily allowable duration may cause noise-induce hearing loss (NIHL). Investigation on the type of task that has high noise level exposure on the maintenance workers was conducted to justify the needs to further detailed of this study. This paper will describe the task analysis on maintenance workers and to identify possible tasks with exposure to high level of noise. It scopes down to grinding crew of the maintenance department of light rail transit. Methods used were real-time sound measurement using a sound level meter, observation and interviews. Then, data were analysed to understand the situation of exposure of noise during rail maintenance. An ergonomic risk assessment was also conducted by adoption of the latest guideline on Ergonomic Risk Assessment (ERA) at Workplace Guidelines recommended by Department of Occupational Safety and Health (DOSH), Malaysia. A hierarchical task analysis (HTA) was generated on the task of the maintenance worker, focusing on rail grinding crew. The newly generated HTA had allowed better understanding about the nature of work and the task conducted by a rail grinder during the work shifts. Tasks involving high noise level was identified. Data recorded shows that the noise level for the blowing activity was relatively high and exceeded the permissible exposure limit of 90dBA. The exposure level was currently controlled by practicing the usage of hearing protection equipment (HPE) and by controlling exposure time in accordance to recommendations of the Factory and Machinery Act (FMA). Thus, it had confirmed that maintenance workers were exposed to high noise levels when performing their daily task. Further studies are needed to investigate the relationship between the duration of exposure and noise-induce hearing loss (NIHL) with consideration of the lifestyles of the maintenance workers.

“…It can be assumed that in addition to decreasing performance, variable master-slave misalignment also increases the cognitive workload of the operator, as they permanently have to adapt to the changing master-slave misalignment. Thus, the importance of a master device that allows the operator to perform the necessary orientational motions without indexing seems evident, especially as Boessenkool et al [12] found that in teleoperated fine positioning tasks, the control of the tool orientation is particularly difficult, even without master-slave misalignment.…”

The handle design of telemanipulation master devices has not been extensively studied so far. However, the master device handle is an integral part of the robotic system through which the user interacts with the system. Previous work showed that the size and shape of the functional rotational workspace of the human-robot system and its usability are influenced by the design of the master device handle. Still, in certain situations, e.g., due to user preference, a specific grasp type handle might be desired. Therefore, in this article, we provide a systematic approach on how to assess and adjust the functional rotational workspace of a human-robot system. We investigated the functional rotational workspace with two exemplary grasp type handles and two different mounting orientations for each handle. The results showed that by adapting the handle orientation in the home configuration of the telemanipulator, the functional rotational workspace of the human-robot system can be adjusted systematically to cover more of the mechanical workspace of the master device. Finally, we deduct recommendations on how to choose and adjust a telemanipulator handle.
