This paper presents a novel system for personalized design of footwear using commercial depth-sensing technologies. The system allows users to virtually try on 3D shoe models in a live video stream. A two-stage object tracking algorithm was developed to correctly align shoe models to moving feet during the try-on process. Tracking was driven by an iterative closest point (ICP) algorithm that superimposed...
In virtual and augmented reality (VR/AR), the interaction is used to designate a set of rules and techniques that allows the user to perform interaction tasks in a virtual/augmented environment. The use of hand gestures is the most natural way to perform an interaction, for this reason gestures recognition has a part in the word of interaction. In this context, the aim is to study the different interaction...
The scientific objective of this paper is to describe an innovative architecture of modular form in sensing and supervision system. In our study, a maintenance work at ATLAS detector in Large Hadron Collider at European Organization for Nuclear Research (CERN), Geneva, Switzerland has been considered. The research challenges lie in the development of real-time data-transmission, instantaneous analysis...
This work presents an implementation of an augmented reality system that does not use fiducial markers for neither estimating the camera pose nor inserting a virtual object but natural marks such as corners of objects that are present in the scene. The system uses a RGB-D dataset for positioning the camera which moves with 6 DOF, for defining a work plane and for superimposing the object on the video...
We present a proof-of-concept study for tracking-based gesture interaction in an augmented reality setting using tablets. By tracking a pen in front of a tablet using it's integrated camera, we are able to map certain motions to gestures, which in turn are used to interact with the application. A comparative user study investigates the feasibility and usefulness of our approach with a simple augmented...
Augmented reality games have the power to extend virtual gaming into real world scenarios with real people, while enhancing the senses of the user. This paper describes the AR-Zombie game developed with the aim of studying and developing mobile augmented reality applications, specifically for tablets, using face recognition interaction techniques. The goal of the ARZombie player is to kill zombies...
Augmented Reality (AR) applications are nowadays largely diffused in many fields of use, especially for entertainment, and the market of AR applications for mobile devices grows faster and faster. Moreover, new and innovative hardware for human-computer interaction has been deployed, such as the Leap Motion Controller. This paper presents some preliminary results in the design and development of a...
Digital projection technology allows for effective and entertaining spatial augmented reality applications. Leveraging the capabilities of reasonably accurate object tracking using commodity cameras and/or depth sensors to determine the 3D position and pose of objects in real time, it is possible to project dynamic graphical content on arbitrary surfaces, such as a person's face. Coupling these capabilities...
We present Robot Devastation, a multiplayer augmented reality game using low-cost robots. Players can assemble their low-cost robotic platforms and connect them to the central server, commanding them through their home PCs. Several low-cost platforms were developed and tested inside the game.
Providing relevant information at the right time in the right place is the major challenge in augmented reality, especially when it is applied in industry related applications. Indeed, by superimposing virtual elements on images which capture the real scene, augmented reality has proved its potential and maturity for facilitating maintenance activities, especially in training, repairing or inspections...
Research of manufacturing support using augmented reality has been advanced. It is a technology to present the appropriate work instructions to a worker through a display device. By using the technology, the worker can perform a task that requires skill, even if a worker is not an expert. Previously, in this technology, static work instructions, such as the component mounting position and assembly...
Wearable devices have emerging in last years with diverse applications for provide user convenience. Health care, sports, safety are some examples of areas in which wearable devices have been applied. This paper describes an overview about wearable architectures found in the literature and presents a novel wearable for monitoring ecological environments. The wearable is composed of a Head-UP Display...
This paper presents a new method for 3D face pose tracking in arbitrary illumination change conditions using color image and depth data acquired by RGB-D cameras (e.g., Microsoft Kinect, Asus Xtion Pro Live, etc.). The method is based on an optimization process of an objective function combining photometric and geometric energy. The geometric energy is computed from depth data while the photometric...
Usage areas of mobile phones have increased in the last 10 years. Although there have been improvements in many areas, most of the developments are in the field of positioning systems. Although the people's lives continue in indoor environments, location-based information system receives data from the satellites, which can detect a person's location in outdoor areas. In indoor areas, satellite signals...
This paper builds on the authors' previous work with Augmented Reality (AR) technology, where interactive three-dimensional (3D) content was developed and combined with traditional printed materials to enhance the visualization and understanding of technical information. In this study, we describe a method to rapidly create custom marker-based AR content using 3D data from real objects and an authoring...
In this paper, we present an information registration method for an Augmented Reality Head-Up Display (AR-HUD) system. The AR-HUD system superimposes driving assistance warnings and instructions that correctly match the real world according to the driver's view. AR information registration is a necessary procedure prior to the presentation of these warnings and instructions. This need is important...
Vision-based Augmented Reality (AR) techniques rely heavily on Computer Vision algorithms for most of their tasks. It is understood that these algorithms require numerous parameters to function and their values can affect their outputs. Oftentimes the results vary greatly when different parameters were used and as a result, the performance of the AR technique that utilises them varies accordingly...
In this paper, we implement a new interaction method for the application of augmented reality using ARToolKit and OpenCV SDK. First, on the basis of the exiting marker-based tracking system, this paper achieved the multi-marker tracking that solved the tracking failure problem when the single marker is partially occluded, which greatly improves the robustness of the registration algorithm. In addition,...
Augmented reality for natural images on mobile devices is currently a research focus. Traditional methods augment natural images mainly by projecting virtual models, putting texts, audio and videos on the images. In this paper, we introduce image composition and image special effects into applications of augmented reality, and proposed an augmented reality method with image composition and image special...
Augmented Reality is one of the most fundamental enabling technologies of this era which modifies our perception to such an extent that we are able to see, hear and feel the ordinary everyday objects in a new and enriched way. This technology is an amalgamation of Real and Virtual Worlds which aims to enhance the physical information by exactly super-imposing the computer generated content on it....
