Spatial Interaction in Augmented Reality

A method for spatial interaction in Augmented Reality (AR) includes displaying an AR scene that includes an image of a real-world scene, a virtual target object, and a virtual cursor. A position of the virtual cursor is provided according to a first …

Face tracking for additional modalities in spatial interaction

A user device receives an image stream from the user side of the user device and an image stream from a target side of the user device. The user device acquires a coordinate system for the user, acquires its own coordinate system, and relates the two …

Exploring real world points of interest: Design and evaluation of object-centric exploration techniques for augmented reality

Augmented reality (AR) enables users to retrieve additional information about real world objects and locations. Exploring such location-based information in AR requires physical movement to different viewpoints, which may be tiring and even …

The utility of Magic Lens interfaces on handheld devices for touristic map navigation

This paper investigates the utility of the Magic Lens metaphor on small screen handheld devices for map navigation given state of the art computer vision tracking. We investi- gate both performance and user experience aspects. In contrast to previous …

Augmented Reality (AR) Capture and Play

Methods, systems, computer-readable media, and apparatuses for generating an Augmented Reality (AR) object are presented. The method may include capturing an image of one or more target objects, wherein the one or more target objects are positioned …

Towards user perspective augmented reality for public displays

We work towards ad-hoc augmentation of public displays on handheld devices, supporting user perspective rendering of display content. Our prototype system only requires access to a screencast of the public display, which can be easily provided …

Designing Mobile Augmented Reality

The development of mobile Augmented Reality application became increasingly popular over the last few years. However, many of the existing solutions build on the reuse of available standard metaphors for visualization and interaction without …

Exploring Distant Objects with Augmented Reality

Augmented reality (AR) enables users to retrieve additional information about the real world objects and locations. Exploring such location-based information in AR requires physical movement to different viewpoints, which may be tiring and even …

Experiences with the Impact of Tracking Technology in Mobile Augmented Reality Evaluations

In this paper, we discuss the impact of tracking technology on user studies of mobile augmented reality applications. We present findings from several of our previous publications in the field, discussing how tracking technology can impact, influence …

360 degree panoramic overviews for location-based services

We investigate 360 degree panoramas as overviews to support users in the task of locating objects in the surrounding environment. Panoramas are typically visualized as rectangular photographs, but this does not provide clear cues for physical …
