  • IoT learning model based on virtual object cognition

    Intelligent service provisioning in the Internet of Things infrastructure can be achieved by discovering and composing most relevant virtual objects and autonomic modification of context information that require learning the system behavior through steady association between the virtual object and the real world object. To meet these challenges, Web-of-Objects enables the objects to be deployed, maintained and operated in the Internet of Things through virtualizing the real world objects with the use of semantic ontology. Learning model can be represented in terms of composite virtual object that is formed by combining multiple functionalities of virtual objects. Different functionalities at the virtual object level and their iteration enable the cognition in virtual object. The creation and functional architecture of virtual object in Web-of-Objects have been discussed. For the efficient discovery and composition of virtual object, a Web-of-Objects based learning model has been proposed in this paper. Finally, to realize the service composition, a use-case scenario has been studied.

  • An enhanced virtual object management scheme for personalized ubiquitous computing services at peer-to-peer

    This paper presents an enhanced virtual object management scheme for a personalized ubiquitous computing service, Virtual Personal World (VPW), at peer-to-peer. In the proposed scheme, more detailed descriptions for virtual objects are added in addition to the existing definitions on communications and data of them, and then two phases of virtual object discovery scheme are applied. Therefore, the management scheme can be individualized more effectively according to users' preferences and behaviors and provide a fast way of finding virtual objects. For performance verification, we have implemented a prototype of the proposed scheme as a part of VPW and compare the speed of finding virtual objects in the proposed scheme with those in other DHT P2P networks. Simulation results shows that the proposed scheme can achieve performance improvements compared with other P2P networks.

During the whole process, data acquiring and virtual object generation are completed automatically, including image smoothing, image edge detection, target silhouette tracking, vector curve compression and real-time rendering. This method improved the degree of automation of virtual object generation in AR applications rather than using pre-built models with digital content creation software. The key steps of the approach are described in detail and a practical application is also given.

  • Replacing a Human Hand by a Virtual Hand and Adjusting Its Posture to a Virtual Object for Its Manipulation in an AR Environment

    This paper discusses virtual object manipulation using a human hand in an AR environment. For this purpose, we need to measure the configuration, which includes the position, pose and posture, of the human hand. However, if we employ a data glove for the measurement, the glove appears in the video images synthesized by AR. If we otherwise employ a vision-based approach, the obtained configuration often includes larger errors due to occlusions among fingers. Moreover, the configuration of the human hand in anyway often includes some cognitive errors in manipulating the virtual object, which is only visible in the synthesized videos. To cope with these problems, we propose to replace the human hand with a data glove with a virtual hand in the video and adjust its configuration so that it properly grasps the virtual objects without errors.

  • Virtual object for evaluating Adaptable K-Nearest Neighbor method solving various conditions of object recognition

    In order for robots to be able to manipulate the proper objects, robots firstly need visual ability to precisely recognize and identify objects. One of the most basic problems with robot vision is that environments can change under various weather conditions (various illuminations). Furthermore, each object's category consists of many objects with various poses. In order to obtain the best performance in term of accuracy and efficiency, we compared three feature extraction approaches that have been widely used to solve this problem: principal components analysis (PCA), linear discriminant analysis (LDA), and contour matching with log polar histogram (LPH). We also introduced an improved algorithm called adaptable k-nearest neighbor (AK-NN) that allows the object recognition system to use an automatic adaptable K value to improve the accuracy of classification. To evaluate the object recognition system, we generated virtual objects with various conditions for realistic testing.

  • Duplication Based Distance-Free Freehand Virtual Object Manipulation

    In this paper, we propose duplication based distance-free freehand virtual object manipulation system for AR. Importance of freehand interaction with virtual objects is getting more attention as research on AR environment is extending its technological basis and AR applications are rising fast. However, a proper freehand virtual object manipulation system with overwhelming performances has not been established yet. In order to achieve both accurate selection and intuitive manipulation, we implement simple idea that user can always manipulate the object by simple grabbing whether the object is within reach or not. Our system utilizes ray-casting based selection of remote object followed by duplication of selected remote object which is located in front of user. Duplicate object can be directly manipulated using user's own hand. Our method suggests delicate manipulation of remote object regardless of distance from the user as well as consistent and flexible operations of both selection and manipulation mode.

  • Single Image Based Illumination Estimation for Lighting Virtual Object in Real Scene

    Rendering virtual objects into real scenes with real illumination can greatly increase the realism of virtual objects and the consistency between the virtual and the real. The main challenge lies in illumination estimation from a single image. This article proposes a novel method of single image based illumination estimation for lighting virtual object in real scene. Only a single image, without any knowledge of the 3D geometry or reflectance, is needed, which greatly increases the applicability of the method. We first estimate coarse scene geometry and intrinsic components including shading image and reflectance image. Then the sparse radiance map of the scene is inferred based on the scene geometry and intrinsic components. Finally, the virtual objects are illuminated by the estimated sparse radiance map. Some experimental results show that this method can convincingly light virtual objects into a single real image, without any pre-recorded 3D geometry and reflectance, illumination acquisition equipments or imaging information of the image.

  • Networked haptic cooperation among multiple users via virtual object coordination to averaged position of peer copies

    This paper proposes a distributed haptic control architecture whose coordination gain at each user site is independent of the number of cooperating peers. In the proposed architecture, users interact through manipulating a shared virtual object (SVO) together. The distributed copies of the SVO are controlled through virtual couplers. At each peer, the gain of the force feedback loop is maintained constant regardless of the number of interacting users by coordinating the local SVO copy to the averaged motion of the other SVO copies. The motion of the SVO representative is computed by averaging the motion of all other SVO copies. A preliminary investigation contrasts the proposed controller to traditional distributed virtual coupling control. The comparison is performed via MATLAB simulations of an exemplary cooperative manipulation performed by three users. The results illustrate that the proposed controller: (1) can render a lighter SVO with decreased position coherence among the distributed SVO copies for the same stiffness of coordination; (2) achieves similar position coherence among the distributed SVO copies for the same SVO mass.

  • New Technique for Prediction of Visually Perceived Location of Virtual Object in Mixed/Augmented Reality Using Observer's Action

    In order to treat the virtual object in the same way as the real object, the authors propose the new technique for the prediction of the visually perceived location. In mixed/augmented reality, the real and virtual objects coexist. Because the real object is directly treated with the observer's body, if the virtual object is not, the observer is confused. Although the best way for direct treatment of the virtual object is that a system of mixed/augmented reality detects the visually perceived location, it is impossible. In the authors' proposal, the visually perceived location is predicted using the observer's action. Such proposal is evaluated by examination of the prediction of visually perceived depth using action that the observer reaches out for the virtual object. The results suggest that the visually perceived depth is predicted by fitting the depth of the hand as a function of action time into the logistic function.
