In this paper we present an approach to simulate the evacuation of crowds in facilities such as hospitals, geriatric clinics, orphanages and etc, where agents adopt different profiles, e.g. workers, patients and families. We use Snook tables to parametrize the effort of people to push patients impacting the people speed when evacuating in this specific context. This model can be applied in games, although our main goal is to contribute with safety systems by computing evacuation times and finding out the number of trained people needed in different scenarios. To control the motion of people in crowds and to avoid collisions we use BioCrowds, but any other crowd simulator could be used as well. Results indicate that the total evacuation time is reduced by having more trained workers, smaller hospital floors and an approximately similar number of rescuers and dependents number of patients and rescuers. In addition, we compare our method with another simulation in a hospital and obtained results were coherent.","PeriodicalId":170922,"journal":{"name":"2018 17th Brazilian Symposium on Computer Games and Digital Entertainment (SBGames)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123492910","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In Virtual Reality (VR), a number of interaction techniques have been proposed to deal with this type of task. They can be based on different metaphors, that define how the interaction is performed. However, it is still not clear how these different metaphors perform under Augmented Reality (AR). We performed two experiments to evaluate two of those interaction techniques. One was based on a pointing metaphor, and the other on a surface interaction metaphor. To achieve this result, a game prototype was developed, where users had to apply the selection techniques to reach a goal and win. We evaluated the impact of two different types of devices and two types of crowd simulation (with and without flocking behavior) in the user interaction. The scenario allowed the user to easily navigate around the scene from an overview perspective. We performed a two-way ANOVA between the variables and found that the technique based on surface interaction metaphor allowed the users to select multiple objects in the shortest amount of time. However, the technique based on pointing metaphor had a higher accuracy. Moreover, both techniques performed better with a crowd with flocking behavior.","PeriodicalId":170922,"journal":{"name":"2018 17th Brazilian Symposium on Computer Games and Digital Entertainment (SBGames)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130043585","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Besides hardware capabilities and high-quality 3-D graphics, the feeling of immersion is augmented by incorporating realistic player-game interactions, including the control of game characters movements based on real/natural movements of the player and objects. To this intent, modern VR gaming usually leverages virtual reality headsets and additional devices/sensors whose costs are normally expensive for ordinary games users. In this paper, we propose a low-cost VR gaming system in which the smartphone is used as display and processing units, and its rear camera is used as the main sensor for controlling the character movements in a first-person shooter game (FPS) developed in this work. The VR game system can operate, on average, at 31 frames per second. Regarding the usability, 19 of 24 interviewed users evaluated the character movement precision as good or very good, while 95.8% considered the gun movement as good or very good. Also, all the users would recommend the movement control system as a real-virtual interaction alternative for VR gaming.","PeriodicalId":170922,"journal":{"name":"2018 17th Brazilian Symposium on Computer Games and Digital Entertainment (SBGames)","volume":"85 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129680517","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The General Video Game AI Competition (GVGAI) is one of the most famous GGP competitions, where controllers measure their performance in games inspired by the Atari 2600 console. Here, the GVGAI framework is used. In games where the controller can perform simulations to develop its game plan, recognizing the chance of victory/defeat of the possible resulting states is an essential feature for decision making. In GVGAI, the creation of appropriate evaluation criteria is a challenge as the algorithm has no previous information regarding the game, such as win conditions and score rewards. We propose here the use of (i) avatar-related information provided by the game, (ii) spacial exploration encouraging and (iii) knowledge obtained during gameplay in order to enhance the evaluation of game states. Also, a penalization approach is adopted. A study is presented where these techniques are combined with two GVGAI algorithms, namely, Rolling Horizon Evolutionary Algorithm (RHEA) and Monte Carlo Tree Search (MCTS). Computational experiments are performed using 20 deterministic and stochastic games, and the results obtained by the proposed methods are compared to those found by their baseline techniques and other methods from the literature. We observed that the proposed techniques (i) presented a larger number of wins and F1-Scores than those found by their original versions and (ii) obtained competitive solutions when compared to those found by methods from the literature.","PeriodicalId":170922,"journal":{"name":"2018 17th Brazilian Symposium on Computer Games and Digital Entertainment (SBGames)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127881991","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recent smartphones and tablets are equipped with efficient Multi-Processing Systemson-Chip (MPSoC) devices, with demanding performance requirements and energy consumption constraints. While not primarily designed for gaming, such mobile machines are quickly climbing to the top of the list of preferred gaming devices, augmented at each new product iteration with stateof-the-art multimedia subsystems and co-processors. Therefore, this work aims at designing and evaluating an efficient A* pathfinding co-processor for reconfigurable gaming devices. The co-processor is designed using Xilinx High-Level Synthesis (HLS) compiler and is implemented in the programming logic of a Xilinx Ultrascale+ Field-Programmable Gate Array (FPGA) embedded with a 64-bit quad-core ARM Cortex-A53 MPSoC, dual-core Cortex-R5 real-time processors, and a Mali400 MP2 graphics processing unit. Extensive performance, circuit-area and energy consumption results shows that the coprocessor running at only 200MHz can efficiently find paths approximately four times faster than one ARM processor running at 1.2GHz for a set of pathfinding benchmarks based on artificial maps and commercial games such as StarCraft and Baldur’s Gate, paving the way for novel dedicated gaming co-processors. Moreover, the co-processor only requires about one third of the system’s total dynamic power.","PeriodicalId":170922,"journal":{"name":"2018 17th Brazilian Symposium on Computer Games and Digital Entertainment (SBGames)","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116247321","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
