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...
In this survey of academic contributions driving augmented reality’s commercial potential and of the industry trends advancing software and hardware developments and emerging applications, the author offers advice on how startups hoping to leverage these advances can compete against senior tech tycoons.
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...
This research comprehensively illustrates the design, implementation and evaluation of a novel marker less environment tracking technology for an augmented reality based indoor navigation application, adapted to efficiently operate on a proprietary head-mounted display. Although the display device used, Google Glass, had certain pitfalls such as short battery life, slow processing speed, and lower...
We present an HMD based AR system comprising visual and inertial sensors. The visual sensor is a camera pair and the inertial sensors consist of an accelerometer and a gyroscope. We discuss the temporal and spatial calibration issues that relate to such a system. We introduce simple yet effective methods for estimating the time lag between the camera and the inertial sensors and for estimating the...
The PhD work on Computer Aided Engineering Education (CAEE) scheme is concerned with the use of computer aids for the enhanced, interactive delivery of educational materials in the field of engineering while maintaining existing pedagogical contents and standards. The work considers two separate components, one for classroom and another for practical hands-on laboratory work in engineering. The CAEE...
Over the last years, indoor localization and navigation is becoming a hot topic. With the increasing number of buildings, indoor positioning and navigation has turned out to be more important than outdoors. In the literature, many papers discuss wireless based indoor positioning systems. Essentially based on Wireless Fidelity (Wi-Fi), Bluetooth, Radio Frequency Identification (RFID) or existing solutions...
In this paper we present a user study evaluating the benefits of geometrically correct user-perspective rendering using an Augmented Reality (AR) magic lens. In simulation we compared a user-perspective magic lens against the common device-perspective magic lens on both phone-sized and tablet-sized displays. Our results indicate that a tablet-sized display allows for significantly faster performance...
Recent advances have made augmented reality on smartphones possible but these applications are still constrained by the limited computational power available. This paper presents a system which combines smartphones with networked infrastructure and fixed sensors and shows how these elements can be combined to deliver real-time augmented reality. A key feature of this framework is the asymmetric nature...
This paper describes a mobile-based system to interact with objects in smart spaces, where the offer of resources may be extensive. The underlying idea is to use the augmentation capabilities of the mobile device to enable it as user-object mediator. In particular, the paper details how to build an attitude-based reasoning strategy that facilitates user-object interaction and resource filtering. The...
An investigation of the technology and human factors that drive augmented reality research describes recent developments in handheld AR, concentrating on localization, tracking, interaction, and visualization, and offers several examples illustrating the vast potential and important applications of AR. A related video can be seen here: http://youtu.be/ol371rIyUFY. It shows several real-world examples...
Augmented reality (AR) is a technique that combines a live view in real-time with virtual computer-generated images, creating a real-time augmented experience of reality. In this paper we show some examples for augmented reality applications and review them from cognitive aspects.
Repetitive practices can facilitate the rehabilitation of the motor functions of the upper extremity for stroke survivors whose motor functions have been impaired. An affordable rehabilitation system for hand motion would be useful to provide intensive training to the patients. Augmented Reality (AR) can provide an intuitive interface to the users with programmable environment and realism feelings...
This paper proposes a method to simultaneously and coherently present visual and laser sensors information through an augmented reality visualization interface further enhanced by stereoscopic viewing. The use of graphical objects is proposed to represent proximity measurements which are superimposed and suitably aligned to video information through image processing. This new methodology enables an...
In this paper we present a system for mobile augmented reality (AR) based on visual recognition. We split the tasks of recognizing an object and tracking it on the user's screen into a server-side and a client-side task, respectively. The capabilities of this hybrid client-server approach are demonstrated with a prototype application on the Android platform, which is able to augment both stationary...
It is extremely challenging to run controlled studies comparing multiple Augmented Reality (AR) systems. We use an AR simulation approach, in which a Virtual Reality (VR) system is used to simulate multiple AR systems. To investigate the validity of this approach, in our first experiment we carefully replicated a well-known study by Ellis et al. using our simulator, obtaining comparable results. We...
Outdoor Augmented Reality typically requires tracking in unprepared environments. For global registration, Global Positioning System (GPS) is currently the best sensing technology, but its precision and update rate are not sufficient for high quality tracking. We present a system that uses Kalman filtering for fusion of Differential GPS (DGPS) or Real-Time Kinematic (RTK) based GPS with barometric...
This paper proposes an approach to mixed environment training of manual tasks requiring concurrent use of psychomotor and cognitive skills. To train concurrent use of both skill sets, the learner is provided real-time generated, in-situ presented visual feedback of her performance. This feedback provides reinforcement and correction of psychomotor skills concurrently with guidance in developing cognitive...
Smart phones are becoming visual computing powerhouses. Using sensors such as camera, GPS, and others, the device can provide a new user interface to the real world, augmenting user's view of the world with additional information and controls. Combining computation with image capture allows new kind of photography that can be more expressive than is possible to obtain with a traditional camera. New...
This paper proposes a new way of providing virtual smart home services using tangible mixed reality (MR), which provides more cost-effective and reliable visualization and simulation of the existing pervasive environment. One of the main characteristics of the proposed approach is capable of embedding virtual objects into the real environment such that it is easy to test the feasibility of the existing...
