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...
With the rapid development of Virtual and Augmented Reality systems, it becomes more and more important to develop an efficient calibration method for optical see-through head-mounted displays (OST-HMDs). In this paper, a modular calibration framework with two calibration phases is proposed. In the first phase, an eye-involved equivalent camera model is proposed in order to compute the spatial position...
This paper introduces a unique type of mixed reality system based on passive-haptic feedback, which enables its user to manipulate real objects with bare hands while seeing its counterpart in the HMD with more information attached. The system provides users in MR systems with a more realistic sense of touch and costs less money comparing to the active force feedback devices. In this paper, accuracy...
Yuanmingyuan is a relic park and only few cultural relics are left due to the looting and burning down in history, which makes that most of the scenic spots of the park look boring. To address such issue, a game-based guidance system for Yuanmingyuan and a time travel game called MAGIC-EYES has been proposed with Augmented Reality technology. Six interactive modes are designed in the proposed system...
This paper introduces a novel augmented reality shooting game named “Soul Hunter”, which has been successfully operating in a theme park in China. Soul Hunter adopts an innovative infrared marker scheme to build a mobile augmented reality application in a wide area. It is an extension of the traditional first person game, in which a player is able to fight with virtual ghost through a gunlike device...

With the modern welding equipment progressing continually and the human-centered concept being accepted widely, the technology degree and safety standards of welder are demanded to farther reinforce. These needs the design of manual arc welding shield should consider both protective capability and assistant performance. But the conventional protection shield which based on the design of machine-centered...
This paper presents an augmented reality gun application named AR-Ghost Hunter. AR-Ghost Hunter is an extension of the traditional first person game which adopts an innovative infrared marker system and portable computer to form a complete mobile AR system. In this system, players are able to fight with virtual ghost through special gun like devices in real environment. The basic issue of the system...
This paper describes an augmented reality application system which can achieve 3-Dimensional perspective effect based on computer vision. In such a system a display screen is installed on a wall beside a window, its user can see the outside scene at any viewpoint with the help of the display screen. In addition, the scene displayed on the screen is matched with the scene through the neighbor window,...
Yuanmingyuan was a vast and magnificent royal garden built continuously by several emperors of the Qing Dynasty. Unfortunately, it was looted and burnt down by the Anglo-French forces in 1860 and suffered from continual damages later on. Because of its special significance in the Chinese history, the reconstruction of Yuanmingyuan has been argued for a long time and visitors could only imagine its...
Flight cockpit head tracking system is an important impetus for head pose tracking in fields of virtual or augmented reality. This paper presents a novel approach to dynamically track pilot's head pose using sensor fusion. The proposed approach utilizes a sensor fusion framework, composed of extended Kalman filters (EKF) and fusion filters (FF), to fuse poses from an inside-out tracking (IOT) and...
Augmented reality (AR) Adventure Game is a wide-area indoor AR application for multiple users in Guangdong science center. Tracking the pose of users' head in wide area is crucial for alignment between virtual and real scene. This paper studies the key issues of wide-area indoor tracking system. Different from previous inside-looking-out vision-based tracking, coded infrared (IR) markers are installed...
Accurate head pose tracking is a key issue for indoor augmented reality systems. This paper proposes a novel approach to track head pose of indoor users using sensor fusion. The proposed approach utilizes a track-to-track fusion framework composed of extended Kalman filters and fusion filter to fuse the poses from the two complementary tracking modes of inside-out tracking (IOT) and outside-in tracking...
In this paper, we propose augmented reality (AR) applications for equipment maintenance. The system is based on the projection and detection of infrared markers. We use an infrared projector to project markers onto the surface of the equipment to be maintained. These markers are invisible to the human-eye, but they could be clearly identified by the infrared camera. As a proof of concept, we have...
An indoor tracking system based on primary and assistant infrared markers is presented in this paper. The system can track the user's head in a large area with high stability and accuracy. And the price of the system is very low. The novel assistant infrared markers with particular spatial characteristic and the primary infrared markers with particular spatio-temporal characteristic are proposed,...
