With the ongoing introduction of wide-FOV VR head-worn displays into the consumer market, the application of VR 3D UIs to professional work environments is attracting increasing attention. One of the most conspicuous concepts is immersive 3D modeling and content creation. In spite of the long research history, there have been very few analyses of the effect of 3D UIs on productivity in 3D design....
A recurring challenge when setting up any Augmented Reality system is integration as well as the correct calibration and registration of the involved devices. To gather, the input data the user has to interact with the system which requires certain knowledge on how to perform the task. It is possible the user performs the current task to the best of his knowledge and still produces suboptimal results...
In this paper, we propose a markerless augmented reality (AR) system that works on multiple mobile devices. The relative positions and orientations of the devices and their individual motions are estimated from 3D information in real space obtained by depth cameras attached to the devices. The system allows multiple users to share the AR space and to interact with the same virtual object. To estimate...
Augmented reality (AR) designers have great potential to enrich children's lives through AR experiences in education and entertainment. A significant difficulty in designing for children is that tremendous physical and cognitive development occurs across the first 10 years of life, and the changes in children's capabilities and limitations impact how these users respond to AR designs. Currently, little...
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...
Collaborative Augmented Reality (CAR) systems allow multiple users to share a real world environment including computer generated images in real time. Currently, the hardware features of most mobile phones not only provide excellent multimedia services, but it also includes wireless network capabilities that provides a natural platform for CAR systems. However, the wide variety of these hardware features...
In this paper we describe a prototypical system for live musical performance in a virtual studio environment. The performer stands in front of the studio camera and interacts with an infrared-laser-based multi-touch device. The final TV image shows the performer interacting with a virtual screen which is augmented in front of herself. To overcome the problem of the performer not seeing this virtual...
In this work, we present an interactive optical see-through HMD (head-mounted device) which makes use of a user's gaze information for the interaction in the AR (augmented reality) environment. In particular, we propose a method to employ a user's half-blink information for more efficient interaction. As the interaction is achieved by using a user's eye gaze and half-blink information, the proposed...
In this paper, we propose the novel interface system for mobile phone using infrared pointer scheme. Our approach exploits mobile augmented reality technology using IR camera. We implemented the proposed mechanism on smartphone and applied the proposed interface to sketchbook application called U-Sketchbook. Users can draw picture on any space available and the IR camera can detect the movement of...
Augmented Reality allows the user to see the virtual objects superimposed upon or composited with the real world. This paper presented the system design of the Multi-Object Oriented Augmented Reality (MOOAR) system for location-based adaptive mobile learning environment and the scenario study. Moreover, the detailed rationales behind the MOOAR system are also discussed in this paper. The implementation...
This paper describes a framework which uses augmented reality for evaluating the performance of mobile computer vision systems. Computer vision systems use primarily image data to interpret the surrounding world, e.g to detect, classify and track objects. The performance of mobile computer vision systems acting in unknown environments is inherently difficult to evaluate since, often, obtaining ground...
In this paper, we present a new immersive multiplayer game system developed for two different environments, namely, virtual reality (VR) and augmented reality (AR). To evaluate our system, we developed three game applications-a first-person-shooter game (for VR and AR environments, respectively) and a sword game (for the AR environment). Our immersive system provides an intuitive way for users to...
The introduction of low power general purpose processors (like the Intelreg Atomtrade processor) expands the capability of handheld and mobile Internet devices (MIDs) to include compelling visual computing applications. One rapidly emerging visual computing usage model is known as mobile augmented reality (MAR). In the MAR usage model, the user is able to point the handheld camera to an object (like...
This paper presents an architecture to support fast prototyping of augmented reality systems, based on virtual reality. The architecture defines simulation services separated from other aspects of the system. These services support incremental evolution of simulated prototypes into nonsimulated systems. Focus is also placed on user interaction,through the definition of an interaction architecture...
Rapid prototyping allows for evaluation of design product in a short period of time. Designers or CEOs may perceive the size and appearance of the product by touching the automatically constructed physical objects produced through rapid prototyping. However, it is usually impossible to change its color, texture, and user interface. In this paper, we introduce 'Augmented Reality based Re-formable Mock-up',...
