Common spatial augmented reality techniques use video projection to superimpose virtual information over a physical scene. As the augmentation happens directly in the real world, multiple users can see the augmented scene, however, the augmentation is the same for all users. We introduce EgoSAR, a new approach that makes it possible to have a personalized, view-dependent augmentation, in multi-user...
Augmented Reality furniture arrangement systems are useful for viewing room or building layouts without having to buy or move real furniture. However, such systems often require users to physically and frequently change their viewpoint of the physical space, which requires manual manipulation of the scene, and are often limited to 2D tablet or phone interfaces. To help address this problem, we have...
Operating forklifts in warehouses is becoming an increasingly difficult task due to higher shelves and narrower aisles. We investigate how Augmented Reality (AR) could aid forklift operators in performing their pallet racking and pick up tasks by superimposing virtual guidelines over a real world camera feed. To test this, we designed and developed a prototype system based on a toy forklift and conducted...
Localizing the user from a feature database of a scene is a basic and necessary step for presentation of localized augmented reality (AR) content. Commonly such database depicts a single appearance of the scene, due to time and effort required to prepare it. To account for appearance changes under different lighting we propose to generate the feature database from a simulated appearance of the scene...
We propose to visualize pre-recorded activity of a person on a movable transparent screen for in-situ reviewing of his/her activity in augmented reality fashion. Activity of the target person was taken as a video by a surveillance camera. Viewers can watch the activity in the scene as if it happened there because segmented image of the target person was projected onto a human-size transparent screen...
Understanding the anatomy of the human body is vital for everyone working in the medical domain. Augmented reality (AR) systems for anatomy teaching, which display virtual information directly on top of a users' body, have proven to facilitate mental mapping compared to traditional teaching paradigms. In this paper, we explore the potential of diminished reality (DR) in the context of anatomy education...
Augmented reality combines real footage taken of a scene with virtual elements. However, most current methods rely on camera localisation and 3D reconstruction or point cloud generation in order to integrate augmented reality to the footage. In contrast, in this work we present a novel method to augment virtual reality to the scene based on the recognition of dominant planes in interior scenes. Our...
3D visualization of breast tumors are shown to be effective by previous studies. In this paper, we introduce a new augmented reality application that can help doctors and surgeons to have a more accurate visualization of breast tumors; this system uses a marker-based image-processing technique to render a 3D model of the tumors on the body. The model can be created using a combination of breast 3D...
This paper discusses a system based on Augmented Reality for Home Exhibition, which supports real-time tracking without Identification Markers, the system uses FAST corner detection and local window matching algorithm to establish the initial 3D maps. It then uses OpenGL ES Graphics Rendering Tools to make the virtual furniture models which established by MAYA on the mobile phone based on the real-time...
Augmented Reality or AR is a technology characterized by virtual content adding on the perception of reality using the existing environment and overlaying additional information, this digital information is shown in a device display in real time. The aim of this study is to implement some tests for a mobile augmented reality system (MAR) and test the potential of AR development tools in a mobile application...
The education system has evolved from mere chalk and slate teaching methodology to presentations and smart board used in classrooms nowadays. In order to make teaching more interactive and interesting, applications involving slice of augmented reality are also developed. In this paper PrEduSense: Smart Education Kit for Pre-Primary Classes using Intel® Real Sense is introduced which consists of all...
Virtual reality replaces the existing world with a simulated one. Augmented reality is, however, in real time. The emerging field of Augmented Reality opens up avenues in numerous fields with education being no exception. Our paper proposes an e-learning system for three-dimensional geometry, which makes use of Augmented Reality to enable the user to comprehend the three-dimensional geometry concepts...
This paper discusses an approach for in-situ creation of augmented reality experiences using friendly markers. We introduce the notion of friendly markers and how we have empirically defined it. A mobile application is built for users to turn the physical markers into augmented reality experiences. The application enables users to recognize and interact with friendly markers. The bottleneck of marker...
Current Mobile Augmented Reality (AR) browsers do not reflect users' immediate contexts and lack support for contextual interaction. Such limitations turn users away from the experience, even those who are genuinely interested in the technology. Mobile AR needs a serious move towards a better experience driven by user generated content. This paper discusses InterAKT, a mobile augmented reality browser...
In this paper we present a large-area interactive mixed reality system where multiple users can experience an event simultaneously. Through the combination of a number of innovative methods, the system can tackle common problems that are inherent in most existing mixed reality solutions, such as robustness against lighting conditions, static occlusion, illumination correction, registration and tracking...
In augmented reality (AR) systems, virtual objects, graphics or texts are added to the real scene to improve the person's perception. Virtual and real information must be aligned strictly in the combination of scenes. The key of augmented reality is 3D registration technology which is based on tracking the artificial marker in the scene effectively. Using linear programming theory, this paper presents...
Wearable augmented reality (AR) is a promising technology for surgical navigation and also for non-medical tasks. Optical see-through displays allow a direct view of the real world augmented with patient related virtual information, which is usually projected on semi-transparent displays placed in front of the eyes. A user-dependent display calibration is required to guarantee a coherent alignment...
With rapidly increasing smartphone user base in the country, many opportunities revolving the same can be explored. India being a multilingual nation, domestic/international tourist needs several language solutions on their fingertips. Applications such as instant language translation, maps, travel assistance, routes, restaurants, banks etc. have become a necessity on smartphones in the current scenario...
The visual tracking of an object is a well-known problem, and it involves many fields of applications. Often a single sensor, the camera, could not provide enough information in order to track the whole object trajectory due to a low updating rate; therefore a multi-sensor system, based also on inertial measurements, could be necessary to improve the tracking accuracy. This leads to the fundamental...
This article explores a way of describing and comparing the local features of the image. Proposed algorithm for construction descriptor of image features, allows to carry out cross-correlation analysis. Proposed algorithm for evaluating similarity between two neighborhoods of features of the image.
