We are developing tools and Environment (OIDE), a graphical tool built on top of the May 2009. methods for multimodal interaction development driven platform. by exploratory test-beds for navigating large information spaces and multi-player mixed-reality OI Kernel games on mobile phones. In this paper, we introduce The OI Kernel [1] is a component-based platform that the OpenInterface framework, the generic and tailored handles distributed heterogeneous components based components that have already been implemented and on different technologies (Java, C++, Matlab, Python, two test-beds we have built using our framework. .NET). The heterogeneity of the platform constitutes a www.oi-project.org great advance from previous approaches. It will allow Related work the integration of existing interaction techniques To date, most tools are designed for specific interaction written in different languages. The platform includes a paradigms, such as camera-based interaction [9] or tool for creating new components from existing code tangible interfaces [7]. Concerning component-based without modifying the original code. The OI kernel toolkits for multimodal interaction, two main references manages the creation and the connection between have guided our study. The first is the Input components by dynamically loading and interpreting Configurator [5] (ICON), which is a tool for building the OI application descriptions or “pipelines”. Pipelines input reconfigurable interfaces. The main limitation of can be created graphically using the OIDE, built on top ICON is that the level of abstraction of its components of the OI kernel. is too low and assemblies of components become too complex. The second is our ICARE tool [2], which is our OIDE previous attempt to create a high level component- The OIDE is a graphical environment that allows direct based approach for building multimodal interaction. manipulation and assembling of components in order to ICARE defines a set of generic components.

As seen in figure 1, each component has a Our model includes three main levels for components: button that allow a designer to start the component. devices, transformation chain and tasks, as shown in Figure 2. Both task and device components can be generic or tailored. For example generic task components are based on Foley’s interactive tasks [6] while generic device components are based on device taxonomies [3]. The transformation chain level defines two types of components: transformation components and composition components. Figure 1.

  • Augmented Reality for Unity: the Artoolkit Package JM Vezien Jan
    Augmented reality for Unity: the ARToolkit package JM Vezien Jan 2016 ARToolkit provides an easy way to develop AR applications in Unity via the ARTookit package for Unity, available for download at: http://artoolkit.org/documentation/doku.php?id=6_Unity:unity_about The installation is covered in: http://artoolkit.org/documentation/doku.php?id=6_Unity:unity_getting_started Basically, you import the package via Assets--> Import Package--> custom Package Current version is 5.3.1 Once imported, the package provides assets in the ARToolkit5-Unity hierarchy. There is also an additional ARToolkit entry in the general menu of unity. A bunch of example scenes are available for trials in ARToolkit5-Unity-->Example scenes. The simplest is SimpleScene.unity, where a red cube is attached to a "Hiro" pattern, like the simpleTest example in the original ARToolkit tutorials. The way ARToolkit for Unity organises information is simple: • The mandatory component for ARToolkit is called a ARController. Aside from managing the camera parameters (for example, selecting the video input), it also records the complete list of markers your application will use, via ARMarker scripts (one per marker). • A "Scene Root" will contain everything you need to AR display. It is a standard (usually empty) object with a AR Origin script. the rest of the scene will be children of it. • The standard camera remains basically the same, but is now driven by a specific ARCamera script. By default, the camera is a video see-through (like a webcam). • Objects to be tracked are usually "empty" geomeries (GameObject--> Create empty) to which one attaches a special AR Tracked Object script.

  • Application of Augmented Reality and Robotic Technology in Broadcasting: a Survey
    Review Application of Augmented Reality and Robotic Technology in Broadcasting: A Survey Dingtian Yan * and Huosheng Hu School of Computer Science and Electronic Engineering, University of Essex, Wivenhoe Park, Colchester CO4 3SQ, UK; [email protected] * Correspondence: [email protected]; Tel.: +44-1206-874092 Received: 26 May 2017; Accepted: 7 August 2017; Published: 17 August 2017 Abstract: As an innovation technique, Augmented Reality (AR) has been gradually deployed in the broadcast, videography and cinematography industries. Virtual graphics generated by AR are dynamic and overlap on the surface of the environment so that the original appearance can be greatly enhanced in comparison with traditional broadcasting. In addition, AR enables broadcasters to interact with augmented virtual 3D models on a broadcasting scene in order to enhance the performance of broadcasting. Recently, advanced robotic technologies have been deployed in a camera shooting system to create a robotic cameraman so that the performance of AR broadcasting could be further improved, which is highlighted in the paper. Keyword: Augmented Reality (AR); AR broadcasting; AR display; AR tracking; Robotic Cameraman 1. Introduction Recently, there is an optimistic prospect on installing Augmented Reality (AR) contents in broadcasting, which is customizable, dynamic and interactive. AR aims at changing the appearance of a real environment by merging virtual contents with real-world objects. Through attaching virtual content on a real-world environment, broadcasting industries avoid physically changing the appearance of a broadcasting studio. In addition, broadcasters can tell a much more detailed and compelling story through interacting with 3D virtual models rather than with verbal descriptions only.

DE GUZMAN, University of New South Wales and Data 61, CSIRO KANCHANA THILAKARATHNA, University of Sydney and Data 61, CSIRO ARUNA SENEVIRATNE, University of New South Wales and Data 61, CSIRO Mixed reality (MR) technology development is now gaining momentum due to advances in computer vision, sensor fusion, and realistic display technologies. With most of the research and development focused on delivering the promise of MR, there is only barely a few working on the privacy and security implications of this technology. is survey paper aims to put in to light these risks, and to look into the latest security and privacy work on MR. Specically, we list and review the dierent protection approaches that have been proposed to ensure user and data security and privacy in MR. We extend the scope to include work on related technologies such as augmented reality (AR), virtual reality (VR), and human-computer interaction (HCI) as crucial components, if not the origins, of MR, as well as numerous related work from the larger area of mobile devices, wearables, and Internet-of-ings (IoT). We highlight the lack of investigation, implementation, and evaluation of data protection approaches in MR. Further challenges and directions on MR security and privacy are also discussed.
