The advancement of virtual reality technologies and context-awareness give rise to new game genres such as \"live-action virtual reality games\", which we proposed in previous works. Live-action virtual reality games create a kind of \"augmented virtuality\" - a mixed-reality where the virtual world is augmented with real-world information. In these games, players wear HMD devices and see a virtual world that is constructed using the physical world architecture as the basic geometry and context information. Physical objects that reside in the physical world are also mapped to virtual elements. Live-action virtual reality games keep the virtual and real-worlds superimposed, requiring players to physically move in the environment and to use different interaction paradigms (such as tangible & embodied interaction) to complete game activities. This setup enables the players to touch physical architectural elements (such as walls) and other objects, \"feeling\" the mixed-reality environment. We propose an architecture that implements a low cost system for live-action virtual reality games that addresses indoor navigation and tracking of physical elements, providing good results due to its accuracy. The system is based on infrared markers, enabling it to operate in the spectral infrared region to work with low optical noise and better precision when compared to solutions based on fiducial markers. Furthermore, this paper describes our system and presents two case studies based on our architecture.","PeriodicalId":102706,"journal":{"name":"2015 14th Brazilian Symposium on Computer Games and Digital Entertainment (SBGames)","volume":"125 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123725114","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}

These simulations may have predefined time step sizes or may use variable time step sizes. These approaches are common in games, but not flexible. In the first approach, when the game runs on a machine with abundant resources, the game does not use the extra capacity to improve simulation quality (task results or presentation). The second approach usually runs the simulation as fast as possible, using the time elapsed between consecutive time steps to scale all computations, so as the simulation runs in real-time. However, this approach wastes processor time and energy and in multi-core hardware scenarios (e.g., GPUs and clusters), the problem of wasting computing resources becomes more severe. In this paper, we propose a parallel and adaptive architecture that employs tardiness policy in multi-core hardware to handle the aforementioned issues. The architecture uses tardiness policy to monitor and change task behavior according to the current conditions of he host hardware. On more powerful computers, the architecture is able to improve task quality if there is spare time available. On less powerful computers, the architecture restricts task functionality so that tasks are able to complete on time. We provide two examples to demonstrate how the architecture works.","PeriodicalId":102706,"journal":{"name":"2015 14th Brazilian Symposium on Computer Games and Digital Entertainment (SBGames)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128199804","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 this work two machine learning techniques, namely, a reinforcement learning approach and an Artificial Neural Network (ANN), are used in a fighting game in order to allow the agent/fighter to emulate a human player. We propose a special reward function for the reinforcement learning approach that is capable of integrating specific human-like behaviors to the agent. The ANN is trained with several recorded battles of a human player. The proposed methods are compared to other two reinforcement learning methods presented in the literature. Furthermore, we present a detailed discussion of the empirical evaluations performed, regarding the training process and the main characteristics of each method used. The results obtained in the experiments indicated that the proposed methods have a good performance against human players and are also more enjoyable to play against when compared to the other existing methods.","PeriodicalId":102706,"journal":{"name":"2015 14th Brazilian Symposium on Computer Games and Digital Entertainment (SBGames)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133289238","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}

Also, it produces rotation data based on a gyroscope, accelerometer and magnetometer embedded on it. The Leap Motion (LM) is a sensor-based cameras and infrared lights, which allows accurately to track the hands motion, including fingers. Therefore, this work describes the use of sensor data fusion techniques to combine the data from both sensors in order to create a 3D virtual simulation in real-time of an arm motion, including the forearm, hand and fingers. The purpose of this combination is also improve the performance, aiming to overcome the main sensors' limitations when they are used individually, as occurs with Myo, which is limited to produce only forearm motion data and the LM, which has a limited field of view and range tracking. The experiment results shows that the studied algorithm is able to combines the data from both sensors achieving a considerable gain in the precision and tracking of the arm.","PeriodicalId":102706,"journal":{"name":"2015 14th Brazilian Symposium on Computer Games and Digital Entertainment (SBGames)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130201921","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}
