The real-time simulation of human crowds has many applications. In a typical crowd simulation, each person ('agent') in the crowd moves towards a goal while adhering to local constraints. Many algorithms exist for specific local ‘steering’ tasks such as collision avoidance or group behavior. However, these do not easily extend to completely new types of behavior, such as circling around another agent or hiding behind an obstacle. They also tend to focus purely on an agent's velocity without explicitly controlling its orientation. This paper presents a novel sketch-based method for modelling and simulating many steering behaviors for agents in a crowd. Central to this is the concept of an interaction field (IF): a vector field that describes the velocities or orientations that agents should use around a given ‘source’ agent or obstacle. An IF can also change dynamically according to parameters, such as the walking speed of the source agent. IFs can be easily combined with other aspects of crowd simulation, such as collision avoidance. Using an implementation of IFs in a real-time crowd simulation framework, we demonstrate the capabilities of IFs in various scenarios. This includes game-like scenarios where the crowd responds to a user-controlled avatar. We also present an interactive tool that computes an IF based on input sketches. This IF editor lets users intuitively and quickly design new types of behavior, without the need for programming extra behavioral rules. We thoroughly evaluate the efficacy of the IF editor through a user study, which demonstrates that our method enables non-expert users to easily enrich any agent-based crowd simulation with new agent interactions.

This paper presents the latest version of the Machinations framework. This framework uses diagrams to represent the flow of tangible and abstract resources through a game. This flow represents the mechanics that make up a game’s interbal economy and has a large impact on the emergent gameplay of most simulation games, strategy games and board games. This paper shows how Machinations diagrams can be used simulate and balance games before they are built.
To aid HR practitioners in their design of firm specific HRM configurations, andcontribute to the state of the art HRM knowledge, we created a simulation model. In this paper we present the simulation model, and the serious game in which it was implemented, but focus on the practical and academical implication of creating and using our initial HRM simulation model.Deciding which HR-practices to select, and how to design them in a multiyear HRMconfiguration is a challenging task for any HR-practitioner due to the large number of interrelated options to pick from. In particular as, according to configurational HRM, the configuration of HR-practices needs to reflect the organizational strategy (vertical alignment) and show internal consistency (horizontal alignment). Currently, no (technological) tool aids HR-practitioners in their quest to design an aligned HRM configuration. To fill this void, we created an HRM simulation model and used it in a serious game which was played during workshops with HR-practitioners.Configurational HRM postulates that HRM configuration need to be both verticallyand horizontally aligned. However, to date, no specific information on how to make these levels of alignment happen is present. As a result, no specific hypothesis based on configurational HRM has been defined and empirical validation of this mode of theorizing is limited. Using the simulation model and serious game we aspire to specify the configurational mode of theorizing with a new level of detail enabling more precise empirical exploration of configurational HRM.The creation of an HRM simulation model and serious game proved to beworthwhile. During the workshops, HR-practitioners stated that the simulation model and game enables them to get to grips with the complexity of designing a firm specific HRM configuration. Furthermore, the simulation model enables us to specify configurational HRM to a new level of detail enabling a wide variety of research opportunities. The simulation model, serious game, and implications are discussed in this paper.

In recent years, disasters are increasing in numbers, location, intensity and impact; they have become more unpredictable due to climate change, raising questions about disaster preparedness and management. Attempts by government entities at limiting the impact of disasters are insufficient, awareness and action are urgently needed at the citizen level to create awareness, develop capacity, facilitate implementation of management plans and to coordinate local action at times of uncertainty. We need a cultural and behavioral change to create resilient citizens, communities, and environments. To develop and maintain new ways of thinking has to start by anticipating long-term bottom-up resilience and collaborations. We propose to develop a serious game on a physical tabletop that allows individuals and communities to work with a moderator and to simulate disasters and individual and collective action in their locality, to mimic real-world scenarios using game mechanics and to train trainers. Two companies–Stratsims, a company specialized in game development, and Society College, an organization that aims to strengthen society, combine their expertise as changemakers. They work with Professor Carola Hein (TU Delft), who has developed knowledge about questions of disaster and rebuilding worldwide and the conditions for meaningful and long-term disaster preparedness. The partners have already reached out to relevant communities in Amsterdam and the Netherlands, including UNUN, a network of Ukrainians in the Netherlands. Jaap de Goede, an experienced strategy simulation expert, will lead outreach activities in diverse communities to train trainers and moderate workshops. This game will be highly relevant for citizens to help grow awareness and capacity for preparing for and coping with disasters in a bottom-up fashion. The toolkit will be available for download and printing open access, and for purchase. The team will offer training and facilitate workshops working with local communities to initiate bottom-up change in policy making and planning.
The IMPULS-2020 project DIGIREAL (BUas, 2021) aims to significantly strengthen BUAS’ Research and Development (R&D) on Digital Realities for the benefit of innovation in our sectoral industries. The project will furthermore help BUas to position itself in the emerging innovation ecosystems on Human Interaction, AI and Interactive Technologies. The pandemic has had a tremendous negative impact on BUas industrial sectors of research: Tourism, Leisure and Events, Hospitality and Facility, Built Environment and Logistics. Our partner industries are in great need of innovative responses to the crises. Data, AI combined with Interactive and Immersive Technologies (Games, VR/AR) can provide a partial solution, in line with the key-enabling technologies of the Smart Industry agenda. DIGIREAL builds upon our well-established expertise and capacity in entertainment and serious games and digital media (VR/AR). It furthermore strengthens our initial plans to venture into Data and Applied AI. Digital Realities offer great opportunities for sectoral industry research and innovation, such as experience measurement in Leisure and Hospitality, data-driven decision-making for (sustainable) tourism, geo-data simulations for Logistics and Digital Twins for Spatial Planning. Although BUas already has successful R&D projects in these areas, the synergy can and should significantly be improved. We propose a coherent one-year Impuls funded package to develop (in 2021): 1. A multi-year R&D program on Digital Realities, that leads to, 2. Strategic R&D proposals, in particular a SPRONG/sleuteltechnologie proposal; 3. Partnerships in the regional and national innovation ecosystem, in particular Mind Labs and Data Development Lab (DDL); 4. A shared Digital Realities Lab infrastructure, in particular hardware/software/peopleware for Augmented and Mixed Reality; 5. Leadership, support and operational capacity to achieve and support the above. The proposal presents a work program and management structure, with external partners in an advisory role.
The objective of DIGIREAL-XL is to build a Research, Development & Innovation (RD&I) Center (SPRONG GROUP, level 4) on Digital Realities (DR) for Societal-Economic Impact. DR are intelligent, interactive, and immersive digital environments that seamlessly integrate Data, Artificial Intelligence/Machine Learning, Modelling-Simulation, and Visualization by using Game and Media Technologies (Game platforms/VR/AR/MR). Examples of these DR disruptive innovations can be seen in many domains, such as in the entertainment and service industries (Digital Humans); in the entertainment, leisure, learning, and culture domain (Virtual Museums and Music festivals) and within the decision making and spatial planning domain (Digital Twins). There are many well-recognized innovations in each of the enabling technologies (Data, AI,V/AR). However, DIGIREAL-XL goes beyond these disconnected state-of-the-art developments and technologies in its focus on DR as an integrated socio-technical concept. This requires pre-commercial, interdisciplinary RD&I, in cross-sectoral and inter-organizational networks. There is a need for integrating theories, methodologies, smart tools, and cross-disciplinary field labs for the effective and efficient design and production of DR. In doing so, DIGIREAL-XL addresses the challenges formulated under the KIA-Enabling Technologies / Key Methodologies for sectoral and societal transformation. BUas (lead partner) and FONTYS built a SPRONG group level 4 based on four pillars: RD&I-Program, Field Labs, Lab-Infrastructure, and Organizational Excellence Program. This provides a solid foundation to initiate and execute challenging, externally funded RD&I projects with partners in SPRONG stage one ('21-'25) and beyond (until' 29). DIGIREAL-XL is organized in a coherent set of Work Packages with clear objectives, tasks, deliverables, and milestones. The SPRONG group is well-positioned within the emerging MINDLABS Interactive Technologies eco-system and strengthens the regional (North-Brabant) digitalization agenda. Field labs on DR work with support and co-funding by many network organizations such as Digishape and Chronosphere and public, private, and societal organizations.
