Augmented reality is popular and rapidly growing direction. It is successfully used in medicine, education, engineering and entertainment. In the paper, basic principles of typical augmented reality system are described. An efficient hybrid visual tracking algorithm is proposed. The approach is based on combining of the optical flow technique with direct tracking methods. It is demonstrated that developed...
Antiphonal singing is a common and important form of expression in Chinese drama. Antiphonal singing requires two actors performs in turns, and their action, expression, gesture need to correspond to the other one. In this paper the authors present a Chinese drama rehearsal system based on phonetic matching and augmented reality to help Chinese traditional drama actor and enthusiasts to rehearse and...
The state of the art VR/AR devices provide access to completely virtual environments or augment information on the existing world seen by the user. Wearable devices encumber the users, and sometimes even cut them off completely from the real world. Users interact with digital avatars instead of the real people themselves. Spatially augmented reality (SAR) instead focuses on illuminating physical spaces...
Augmented Reality (AR) is an emerging field, which is evolving exponentially. Its concept is to coalesce the virtual world into the real world. The augmented reality intent to enhance our perception of the real world by integrating virtual objects. The existing Augmented Reality Hand gesture control systems detect hand gesture and embed the virtual object in augmented reality using markers and motion...
Urban environment constitutes a challenging area for pedestrian navigation. However, with the recent increase of pedestrians owning devices (e.g. smartphones), complementary data provided by integrated low cost sensors (camera, Inertial and Magnetic Measurement Unit and GNSS receiver) may be used in a coupling process to accurately estimate the pose (i.e. 3D position and 3D orientation) of a handheld...
In recent time devices like Google Glass and Oculus Rift gained a lot of public attention. So the field of Virtual and Augmented Reality has become a more and more attractive field of study. Optical Stereo See-Through Head Worn Displays (OST-HWD or OST-HMD) can be used for Augmented Reality, but have to be calibrated. This means, that one has to find a configuration, that aligns the image shown on...
Markerless Augmented Reality (AR) registration using the standard Homography matrix is unstable, and for image-based registration it has very low accuracy. In this paper, we present a new method to improve the stability and the accuracy of marker-less registration in AR. Based on the Visual Simultaneous Localization and Mapping (V-SLAM) framework, our method adds a three-dimensional dense cloud processing...
This paper presents an alternative navigation tool that can be used in indoor environment. This is due to restrictions on GPS signals that cannot be detected in indoor locations. The work presented here shows the development of an interactive indoor localization system that uses live input video capture and can identify location markers to indicate its current location. In addition, augmented reality...
We designed an augmented reality interface for dialog that enables the control of multimodal behaviors in telepresence robot applications. This interface, when paired with a telepresence robot, enables a single operator to accurately control and coordinate the robot's verbal and nonverbal behaviors. Depending on the complexity of the desired interaction, however, some applications might benefit from...
In context of Industry 4.0 Augmented Reality (AR) is frequently mentioned as the upcoming interface technology for human-machine communication and collaboration. Many prototypes have already arisen in both the consumer market and in the industrial sector. According to numerous experts it will take only few years until AR will reach the maturity level to be deployed in productive applications. Especially...
New Internet of Things open source technologies, middlewares, and programming languages, make the quick integration of devices, systems and cloud services easier than never before. With their utilization, complex tasks such as object detection, tracking and tracing, can be easily realized, even by embedded devices in a fraction of time. The interplay of highly heterogeneous IoT devices and open source...
Museum visitors need support tools to facilitate their informal learning. In this paper, we present ARCoins, an augmented reality app to support informal learning about numismatics. Our app helps museum visitors to read the deteriorated text of coins and also shows additional information that offers a clear idea of the general meaning of the coinage of the coins. The app recognizes the real coins...
Microbial science is inevitably involved in human daily life because these creatures live around us. They are both useful and punishable. If the people have knowledge about microorganisms, it can control the microbes that cause the wicked things, and it can also be useful to use microorganisms effectively. Currently, the study still use the microscope in the education. There are limitations when exploring...
The combination of augmented reality (AR) and location-based services provides mobile users with an intuitive and easy way to access the real-world aware information via their mobile devices, as connecting the physical and cyber world. However, mobile AR interactions limit target objects that are located within a specific distance of the current location of users. In this paper, we propose a new service...
E-books have an advantage over printed books in that they allow users to read multiple books on a device such as a tablet or a smartphone. However, e-books also have drawbacks, such as the lack of book weight and of paper-like texture. This study proposes a method in which a user can read while experiencing the tactile sensations of book weight and paper feel through the superimposed display of an...
In this paper we describe a new method for determining gaze depth in a head mounted eye-tracker. Eye-trackers are being incorporated into head mounted displays (HMDs), and eye-gaze is being used for interaction in Virtual and Augmented Reality. For some interaction methods, it is important to accurately measure the x-and y-direction of the eye-gaze and especially the focal depth information. Generally,...
Reliably localizing and tracking displays moving relative to content in the physical world is one of the primary technical challenges facing all augmented reality systems. While significant progress has been made in recent years, all approaches remain limited to functioning only in certain environments and situations. Attempts to improve solution generality via additional sensors (e.g., depth sensors,...
Augmented reality has seen a fast-growing gain of interest in the last few decades. Due to technological advances, smartphones are now devices that allow to experience augmented reality systems, anytime and anywhere. Although its emerging success among users, some problems AR have been reported inhibiting its full acceptance in our digital society. The aim of this paper is to present a study about...
The commonly used 2D Display is limited in aiding operators to control unmanned aerial vehicles (UAVs) within complex environments, due to its weak immersion. This paper proposes a data-driven 3D augmented reality approach. Pre-known data and experience can be integrated into to constructing a 3D virtual scenario. Furthermore, the on-board sensor data is continuously updated to this scenario during...
This paper presents an augmented-reality based interaction gear game which is designed to be used as a learning material of Science and Technology course for elementary school students. With this game, the authors hope to increase concentration, interest, and efficiency of learning in class. Basically, through obtaining the coordinates of human skeleton with Kinect sensor, we are able to identify...
