In this paper, a registration method for outdoorwearable AR systems is described. Our approach is basedon using a high precision gyroscope, which can measure3DOF angle of head direction accurately, but with somedrift error. We solved the drift problem ...

Augmented Reality (AR) both exposes and supplementsthe user's view of the real world. Previous AR work hasfocussed on the close registration of real and virtual objects,which requires very accurate real-time estimates ofhead position and orientation. ...

Optical tracking systems allow three-dimensional inputfor virtual environment applications with high precision andwithout annoying cables. Spontaneous and intuitive interactionis possible through gestures. In this paper, we presenta finger tracker that ...

In this papel, we propose a new approach to buildingaugmented reality (AR) systems using a component-basedsoftware framework.This has advantages for all parties involved with AR systems.A project manager can reuse existing components innew applications; ...

This paper describes an experiment conducted tocompare three technologies in delivering a multi-stepmaintenance procedure to a factory worker. Optical see-through augmented reality, a web browser and atraditional paper-based manual used as control were ...

Correct registration of virtual objects into real scenesrequires robust estimation of camera pose. Since most augmentedreality applications also require real-time performancein potentially restricted environments with no a priorimotion model, we seek ...

This paper presents a summary of a new software architecturewe have developed, known as Tinmith-evo5, which isdesigned as one possible methodology for writing complexAR applications. While software for 2D environments is verymature, in the 3D case there ...

In this paper, we propose a fast method to synthesize a realisticimage under novel lighting directions with three color images.In the method, we use a look-up table procedure to estimatethe surface orientations, instead of complex computations.Moreover, ...

In this paper, a new concept for markerless optical trackingcalled "tracking with reference images" is introduced.This concept provides a flexible and praticable frameworkand is especially relevant for outdoor augmented-reality applications,for which no ...

The Mixed Reality Stage is an Augmented Reality environmentwhich aims to support creative and collaborativestage design processes. In this application scenario theproper simulation of real lighting is crucial for a seamlessintegration of virtual objects ...

In this paper we discuss our work on applying mediatheory to the creation of narrative augmented reality (AR)experiences. We summarize the concepts of remediationand media forms as they relate to our work, argue for theirimportance to the development of ...

We developed a system for augmented realityvisualization of ultrasound images. This system is basedon our earlier "augmented workspace" setup.The user wears a custom video-see-through head-mounteddisplay (HMD). Two color video camerasattached to the HMD ...

We present a system for planar augmented reality basedon a new real-time affine region tracker. Instead of trackingfiducial points, we track planar local image patches, andbring these into complete correspondence, so a virtual texturecan directly be ...

Augmented reality (AR) research has progressed in greatstrides over the past few years. Most currentdemonstrations focus on providing robust trackingsolutions since this is the most critical issue whendemonstrating AR systems. An issue that is ...

Wearable augmented reality (AR) can help the task of auser by adding virtual objects to his view on the realworld. To save power in the mobile unit, rendering can beoffloaded to the backbone as much as possible. However,because of low latency ...

The combination of mobile computing and collaborativeAugmented Reality into a single system makes the powerof computer enhanced interaction and communication inthe real world accessible anytime and everywhere. Thispaper describes our work to build a ...
