In this paper we introduce high performance wait-free hash maps for the System access of Components within the ECS pattern. This allows non-locking read and write operations, leading to a highly responsive low-latency data access while maintaining a consistent data state. Furthermore, we present centralized as well as decentralized approaches for reducing the memory demand of these memory-intensive wait-free hash maps for diverse RIS applications. Our approaches gain their efficiency by Component-wise queues which use atomic markup operations for fast memory deletion. We have implemented our new method in a current RIS and the results show that our approach is able to efficiently reduce the memory usage of wait-free hash maps very effectively by more than a factor of ten while still maintaining their high performance. Furthermore, we derive best practices from our numerical results for different use cases of wait-free hash map memory management in diverse RIS applications.","PeriodicalId":131714,"journal":{"name":"2016 IEEE 9th Workshop on Software Engineering and Architectures for Realtime Interactive Systems (SEARIS)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132671095","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}

Its fulfilment is already challenging for low-interactive application areas. It is additionally complicated by complex system designs of Real-time Interactive Systems (RISs), required for Augmented, Mixed, and Virtual Reality, as well as computer games. If such systems incorporate AI methods, as required for the implementation of multimodal interfaces or smart environments, it is even further exacerbated. Existing approaches strive to establish software technical solutions to support the close temporal and semantic coupling required for multimodal processing and at the same time preserve a general decoupling principle between involved software modules. We present two key solutions that target the semantic coupling issue: (1) a semantics-based access scheme to principal elements of the application state and (2) the specification of effects by means of semantic function descriptions for multimodal processing. Both concepts are modeled in an OWL ontology. The applicability of our concepts is showcased by a prototypical implementation and explained by an interaction example that is applied for two application areas.","PeriodicalId":131714,"journal":{"name":"2016 IEEE 9th Workshop on Software Engineering and Architectures for Realtime Interactive Systems (SEARIS)","volume":"81 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115196002","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}

Contemporary game engines, such as Unity and Unreal, feature component-based architectures, in which an object's appearance and behavior is determined by a collection of component scripts added to that object. This design pattern allows common functionality to be contained within component scripts and shared among different types of objects. In this paper, we describe a flexible framework that enables programmers to design modular, reusable widgets for real-time interactive systems using a collection of component scripts. We provide a reference implementation written in C# for the Unity game engine. Making an object, or a group of objects, part of our managed widget framework can be accomplished with just a few drag-and-drop operations in the Unity Editor. While our framework provides hooks and default implementations for common widget behavior (e.g., initialization, refresh, and toggling visibility), programmers can also define custom behavior for a particular widget or combine simple widgets into a hierarchy and build arbitrarily rich ones. Finally, we provide an overview of an accompanying library of scripts that support functionality for testing and networking.","PeriodicalId":131714,"journal":{"name":"2016 IEEE 9th Workshop on Software Engineering and Architectures for Realtime Interactive Systems (SEARIS)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125237566","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}

Low latencies are required for VR to reduce perceptual artifacts and cyber sickness. Additionally, latency jitter denotes the variance in the pattern of latency changes which additionally may cause unwanted effects. This paper analyzes latency jitter caused by typical inter-thread communication (ITC) techniques commonly used in todays computer systems employed for VR, the influence of the operating system scheduler, and the effect of different garbage collection (GC) methods to understand their effect on latency spikes, here for different Java Virtual Machines (JVM). We measure the scalability and latencies for various ITC techniques with an increasing number of threads and actors performing prototypical concurrent tasks. Four different benchmark implementations on a vanilla Linux kernel as well as on a real-time (RT) Linux kernel assess if a RT variant of a multiuser multiprocess operating system can prevent latency spikes and how this behavior would apply to different programming languages and ITC techniques. We confirmed that scheduler and prioritization of the VR application both play an important role and identified the impact they have on the implementation strategies. Also, Linux RT can limit the latency jitter at the cost of throughput for certain implementations. As expected, the choice of a GC method also is critical and will change the latency patterns drastically. As a result, we suggest that coarse grained concurrency should be employed to avoid adding up of scheduler latencies and unwanted latency jitter for the native ITC case, while actor systems are found to support a higher degree of concurrency granularity and a higher level of abstraction.","PeriodicalId":131714,"journal":{"name":"2016 IEEE 9th Workshop on Software Engineering and Architectures for Realtime Interactive Systems (SEARIS)","volume":"29 13","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133008660","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}
