“…Milgram and Colquhoun [19] introduced a continuum to represent different types of viewpoint centricity. Tönnis et al gave the definitions of three key classes on the continuum: egocentric, egomotion and exocentric in their survey paper [31]. AR interfaces presenting the physical world and/or the virtual contents from multiple exocentric viewpoints have been explored in [28] and [30].…”

The availability of powerful consumer-level smart devices and off-the-shelf software frameworks has tremendously popularized augmented reality (AR) applications. However, since the built-in cameras typically have rather limited field of view, it is usually preferable to position AR tools built upon these devices at a distance when large objects need to be tracked for augmentation. This arrangement makes it difficult or even impossible to physically interact with the augmented object. One solution is to adopt third person perspective (TPP) with which the smart device shows in real time the object to be interacted with, the AR information and the user herself, all captured by a remote camera. Through mental transformation between the user-centric coordinate space and the coordinate system of the remote camera, the user can directly interact with objects in the real world. To evaluate user performance under this cognitively demanding situation, we developed such an experimental TPP AR system and conducted experiments which required subjects to make markings on a whiteboard according to virtual marks displayed by the AR system. The same markings were also made manually with a ruler. We measured the precision of the markings as well as the time to accomplish the task. Our results show that although the AR approach was on average around half a centimeter less precise than the manual measurement, it was approximately three times as fast as the manual counterpart. Additionally, we also found that subjects could quickly adapt to the mental transformation between the two coordinate systems.

“…In the case that augmented content is mounted to the user, the placement can be at a static position, i.e., the users palm, or it can be floating nearby the user, we then call this a usercentered augmentation [24]. The picture sphere by Georgel et al [9], a virtual, augmented sphere surrounding the user with the head as center shows automatically layouted pictures floating on the sphere.…”

Gaze tracking in Augmented Reality is mainly used to trigger buttons and access information. Such selectable objects are usually placed in the world or in screen coordinates of a head-or hand-mounted display. Yet, no work has investigated options to place information with respect to the line of sight.This work presents our first steps towards gaze-mounted information visualization and interaction, determining boundary conditions for such an approach. We propose a general concept for information presentation at an angular offset to the line of sight. A user can look around freely, yet having information attached nearby the line of sight. Whenever the user wants to look at the information and does so, the information is placed directly at the axis of sight for a short time.Based on this concept we investigate how users understand frames of reference, specifically, if users relate directions and alignments in head or world coordinates. We further investigate if information may have a preferred motion behavior. Prototypical implementations of three variants are presented to users in guided interviews. The three variants resemble a rigid offset and two different floating motion behaviors of the information. Floating algorithms implement an inertia based model and either allow the user's gaze to surpass the information or to push information with the gaze. Testing our prototypes yielded findings that users strongly prefer information maintaining world-relation and that less extra motion is preferred.
