Social Media Data in an Augmented Reality System for Situation Awareness Support in Emergency Control Rooms
During crisis situations, emergency operators require fast information access to achieve situation awareness and make the best possible decisions. Augmented reality could be used to visualize the wealth of user-generated content available on social media and enable context-adaptive functions for emergency operators. Although emergency operators agree that social media analytics will be important for their future work, it poses a challenge to filter and visualize large amounts of social media data. We conducted a goal-directed task analysis to identify the situation awareness requirements of emergency operators. By collecting tweets during two storms in Germany we evaluated the usefulness of Twitter data for achieving situation awareness and conducted interviews with emergency operators to derive filter strategies for social media data. We synthesized the results by discussing how the unique interface of augmented reality can be used to integrate social media data into emergency control rooms for situation awareness support.

Habits Over Routines: Remarks on Control Room Practices and Control Room Studies
The evolution of computer tools has had profound impacts on many aspects of control rooms and control room studies. In this paper, we discuss some key assumptions underpinning these studies based on a new case of the electricity distribution control rooms, where the reliability of the electricity infrastructure is managed by a combination of planning and real-time maintenance. Some of these practices have changed remarkably little over the past decades – partially because they have been considered to have been ‘digitalized’ since the 1950s and have continued to amass digital solutions from different periods. Hence, the gradual transformation of control room work demands nuanced attention, both conceptual and empirical. To outline a framework for this work, we provide a conceptualization of organizational routines, habits, and reflectivity and synthesize existing CSCW and control room literature. We then present an empirical study that demonstrates our concepts and shows how they can be applied to study cooperative work. By addressing these aims the paper complements, and advances, the important topics recognized in this special theme issue and hence develops new research openings in CSCW. We address the necessity to avoid implicit determinism when analyzing new digital support tools and suggest focusing on how working habits mediate social changes, distribution, and decentralization in representing the power distribution in control rooms.

Exploring the use of IoT Data for Heightened Situational Awareness in Centralised Monitoring Control Rooms
This paper traces the expansion of a network of IoT sensors to improve the effectiveness of a centralised control room in Brazil in anticipating natural hazards. This centralised model relies on using IoT data by highly qualified experts replacing previous smaller local structures. We draw on the notion of Situational Awareness to carry out the study. Results show that although the operators were not always familiar with the characteristics of locations, the use of IoT data heightened their situational awareness in the centralised control room by improving perception and comprehension. However, they still relied on local knowledge and learned experiences to support projection and anticipation of risks. The study highlights that although data analytics systems are capable of expanding operators’ perception of local elements, they must be complemented by local richer forms of information, needed to anticipate risks and make critical decisions with major impact on local population.

Usability of Mobile Control Room and CCTV Systems for Crowd Control at Large-Scale Events with the Occurrence of a Large Number of People With Focus on the Czech Republic
This article deals with the issue of the use of modern instruments for crowd control, in particular the use of a mobile closed-circuit television system connected directly to the control room during largescale events. The article has two aims: to check the usability of this type of system especially from the perspective of increasing the safety of event visitors, and to identify the optimal technical solution for crowd monitoring and management and possible obstacles for deployment in the field. The article further focuses on the practical usability of the information obtained through the mobile camera system and the control centre for increasing the safety of event visitors from the perspective of security managers. The conducted investigation identified obstacles to the deployment of a mobile camera system as well as described the optimal parameters for the use of a mobile camera system, and it collected feedback from the security team participating in the security management of the event. The results of the contribution enable easier orientation in the selection of suitable hardware and software for crowd control; Key vulnerabilities in deploying mobile CCTV systems were identified, including issues such as data transmission stability over LTE networks and the financial costs of alternative solutions like satellite connections. Based on field testing and feedback from security teams, recommendations were made to improve the system’s effectiveness and adaptability, leading to more precise decision-making and proactive risk management at large-scale events.

Analysis of operator’s activity in control rooms of underground coal mines
The analysis for estimating operator’s activity and quantity of information in control rooms of underground coal mines is presented in this paper. Monitoring of operators in control rooms was conducted in mines Rembas, Soko, Ibar, Jasenovac and Stavalj. The network models are used during the analysis of operator’s activity in control rooms. The result of the analysis is proposed critical path network model. The application of network models improves the quality and level of research, making it more efficient. Most of the analysed information are related to normal and alarm state data received from the mine shaft and operator’s response to this data. Results are given according to actual scope of work depending on the work dynamics in underground coal mines, via histogram of changes in average number of activities per 1 h for 24-h period, then number of operator’s activities per work hour and insight into the global view of technological process in the coal mine with focus on the work scope of mine workers. Analysis of operator’s activities presented in this paper determines the relations between devices in control rooms and operators’ capabilities in order to get better ergonomic design of control rooms.

Towards Speech Recognition and Training Utilization in the Nuclear Power Main Control Room
Speech, as the material shell of language, is the external form of language, and is the symbol system that most directly records people’s thinking activities. As a means of interaction, it has the characteristics of simplicity and speed. For a long time, due to insufficient recognition accuracy, it cannot be applied in industry. However, with the rapid development of big data and machine learning technology, the training effect of speech model has greatly increased, and the reliability of speech recognition has been greatly improved. The application of speech interaction in nuclear power plants with extremely high safety requirements brings feasibility. The purpose of this system is to establish an intelligent speech control system and its related speech model training system, and use Kaldi and Python scripts as model training scripts to train the corpus. And designed experiments to verify that after using speech recognition, it can effectively reduce the operation time by about 45%, and the overall task execution efficiency has been significantly improved. Therefore, the use of speech recognition can significantly reduce the operator’s task load and reduce the probability of human error.

KISTI remote control room for CDF and Belle II collider experiments
Particle collider experiments would be continued even when one is not present at the laboratory (on-site). To achieve this, we require an e-Science paradigm of studying particle physics anytime anywhere. One of the components for establishing this paradigm is a remote control room for data acquisition (DAQ). We developed and embedded a remote control room at the Korea Institute of Science and Technology Information (KISTI). Since then, we have been adopting on/offline shifts for conducting collider experiments at KISTI, that is, the experiments are done even when we are not on-site. In this paper, we introduce our experience of our remote control room for both CDF and Belle II experiments. This remote control room includes international networks, security, DAQ systems, data transfers, and monitoring systems. We also presented the results of the shifts done in the remote control room at KISTI.

Remote situatedness beyond the control room: enhanced seeing and sense of place in railway operations
This paper contributes to the long-ongoing research on control room work by exploring the work practices of traffic controllers and information officers in the domain of train traffic. This study examines how distributed, socially, spatially, and temporally dynamic work activities are enacted within train traffic control rooms. By exploring the situated knowledge of traffic controllers and information officers, we identify the challenge of maintaining remote engagement with, and attachment to, places beyond the control room. By employing a workplace study approach, the paper illustrates how the workers manage the demands of being distributed and dependent on artefacts, as well as their acquired ability to ‘see’ the rail, while physically present elsewhere. We introduce the concept of ‘sense of place’ to better understand the remote aspects of work and how workers develop and maintain their engagement with railway operations in locations far from their own. To conceptualise this phenomenon, we introduce a new term—remote situatedness. This concept integrates cognitive and technological aspects of enhanced seeing with the sense of place, capturing professionals’ ability to engage with distant locations. Our findings highlight three key examples: Mutually enacted situated seeing, Mediated sense of place, and Failed sense of place. These illustrate how remote situatedness is enacted, technologically mediated, and challenged. In conclusion, the paper highlights the need to put the workers’ engagement with their material and social environment at the core of control room research and suggests future research directions for studying work practices from a holistic perspective.
