A fiducial marker system is a system of unique 2D (planar) marker, which is placed in an environment and automatically will be detected with a camera with a help of a corresponding detection algorithm. Application areas of these markers include industrial systems, augmented reality, robots navigation, human-robot interaction and others. Marker system designed for such different applications must be...
Parking could become a nightmare on a busy day, in a city like Delhi (India), which has about 7.35 million cars, as per MORTH Barclays Research (2012). An average of seventeen minutes and considerable amount of fuel is wasted in an effort to find a parking spot every time. Additional stress is induced due to parking hassles starting from finding an empty parking spot to relocating the car later. We...
This paper presents an Augmented Reality (AR) comprehensive assembly system for the multi-interactive creation of assembly processes. The special multimodal interface allows the presentation of not only new types of visual display but also interestingly designed voice instructions and material flow management. The system simulates many-sided and complicated assembly tasks in various areas of manufacturing...
As it can be seen in a developed society, the cities grow day to day, it gives the idea that in the future the major part of the people around the world will live in a city. The term digital city was given to know how the cities will be able to receive these people. Hence, it is important to study how new technologies can improve life quality in several aspects, including the tourism. About tourism,...
The article describes an application of VLC (Visible Light Communication) for IoT (Internet of Things) nodes authentication and metadata exchange in the field of augmented reality. A practical use-case of presented communication system is provided and benefits of using such technique are explained. A smartphone camera based platform and advanced image processing is used for data reception and as a...
This paper documents a pilot study evaluating a simple approach allowing users to eat real food while exploring a virtual environment (VE) through a head-mounted display (HMD). Two cameras mounted on the HMD allowed for video-based stereoscopic see-through when the user’s head orientation pointed toward the food, and the VE would appear when the user turned elsewhere. The pilot study revealed that...
Peripheral vision loss (also called tunnel vision) is one of the main visual field disorders that can be very frustrating, and affect confidence and main activities of the patient. In this paper, two promising solutions for the peripheral vision loss are presented and discussed. The first one uses optical see-through glasses that are augmented by computer-generated images to notify the user about...
We propose a realtime plane detection method for projection-based Augmented Reality (AR) system in an unknown environment. While previous works usually designate space, the plane detection method automatically detects multiple planes based on the proposed constrained sampling strategy in RAndom SAmpleing Concensus (RANSAC). For each plane, an area for projection is selected for contents while considering...
Augmented Reality (AR) introduces vast opportunities to the industry in terms of time and therefore cost reduction when utilized in various tasks. The biggest obstacle for a comprehensive deployment of mobile AR is that current devices still leave much to be desired concerning computational and graphical performance. To improve this situation in this paper we introduce an AR Edge Computing architecture...
Geometry is an interesting area of mathematics. It opens to many different approaches and closely relates to our everyday lives. However, when students recall their experiences of learning geometry, many of them regards it as not only unpleasant experiences but often also difficult experiences. The traditional materials and tools such as pens, papers, blackboards, textbooks and/or classical methodologies...
Augmented Reality (AR) merges real and virtual objects in order to make a richer environment with additional useful virtual information. Producing AR maintenance training depends on two major points that will be Interactivity and Reusability. Recently Augmented Reality becomes the new technology revolution in software applications such as (entertainment, training, military, E-shops and games), and...
This work seeks to apply the emerging virtual and mixed reality techniques to visual exploration and visualization of earth science data. A novel system is developed to facilitate a collaborative mixed reality visualization, enabling both in-situ and off-site users to simultaneously interact with and visualize science data within mixed reality realm. We implement the prototype system in the context...
An effective and simple method is proposed for multi-camera collaborative tracking, based on the prioritization of all tracking units, and then modeling the discrepancy between different tracking units as a locally static transformation error. Static error compensation is applied to the lower-priority tracking systems when high-priority trackers are not available. The method does not require high-end...
For live television broadcast such as the educational program for children conducted through viewer participation, the smooth integration of virtual contents and the interaction between the casts and them are quite important issues. Recently there have been many attempts to make aggressive use of interactive virtual contents in live broadcast due to the advancement of AR/VR technology and virtual...
The objective of this research is to compare the effectiveness of different tracking devices underwater. There have been few works in aquatic virtual reality (VR) — i.e., VR systems that can be used in a real underwater environment. Moreover, the works that have been done have noted limitations on tracking accuracy. Our initial test results suggest that inertial measurement units work well underwater...
View management techniques are commonly used for labelling of objects in augmented reality environments. Combining with image analysis, search space and adaptive representations, they can be utilized to achieve desired labelling tasks. However, the evaluation of different search space methods on labelling are still an open problem. In this paper, we propose an image analysis based view management...
The concept of Augmented Reality is a technology in which the interaction between the human-computer that can generate two-dimensional or three dimensional object in real time. Augmented reality can provide the necessary functions and information in its application. In this case the augmented reality (AR) just need a tool like a camera that can capture images by detecting the object without the marker...
Augmented Reality (AR) is an active and exciting topic aiming to create intuitive computer interface by blending reality and virtual reality. One challenge of AR is to align virtual data with the environment. Typically, one uses a marker-based approach such as a thick-bordered black and white 2D marker which allows one to recover the relative pose (location and orientation) of a camera in real time...
We grew up interacting with the physical objects around us. And there are large number of them that we use everyday. These objects are more fun to use than our computing devices. Taking about objects, another thing that get's attached with objects is gestures; how we manipulate these objects & how we use them in everyday life. These gesture are used to interact with objects as well as to interact...
